Spot Reduction

You cannot spot-reduce fat from your body. I cringe when I see an informercial for one of the many ab busters claiming that you can lose five inches off your waist and drop three dress sizes in a month simply by using their product for five minutes a day. These claims are flagrant misrepresentations that border on consumer fraud. Weight training helps develop shape and hardness in your physique. It cannot make an area of your body smaller, no matter how often or intensely you exercise a given muscle. In the case of the abdominals, training your stomach with crunches, sit-ups, leg raises, or any other abdominal exercise will serve only to increase muscle tone in that area. These exercise will do nothing to flatten your stomach, no matter how hard you try.    

       
    Initially, the thought of training your entire body every workout is intimidating. This workout is not a cakewalk, but its difficulty is somewhat mitigated by a reduction in the total volume and intensity of the routine. As you will see, the system is configured in a way that optimizes your body's recuperative abilities and builds a foundation of muscle without completely draining your resources. The following is the protocol for the weight-training component of the body-conditioning routine:    
       
    Exercises: For each muscle group, you will use only one exercise per training session. Each week you will work your entire body three times. Although training your muscles this frequently can sometimes be overwhelming, the sparseness of the workload will alleviate the risk of overtraining. By performing only one exercise per muscle group, you limit the amount of stress applied to each muscle. This allows you to recuperate quickly from a workout and enables you to train each muscle on a regular basis.    
       
    Sets: You should perform three sets of each exercise. This provides ample muscular stimulation without overtaxing the muscles. Do not move from one exercise to the next, as in a circuit routine. Rather, perform one set of an exercise, rest, perform your second set, rest, and then do your third set. This will keep the blood circulating through a muscle group, which increases your muscular pump and thereby augments definition. After finishing three sets of an exercise, move on to the next muscle group and perform your subsequent sets in a similar fashion.    
       
    Rest: You should rest no more than 30 seconds between sets. This will heighten exercise intensity and increase the aerobic benefit of the workout. In most cases, your routine will take slightly longer in the initial stages of training. As a novice, you will be unfamiliar with the intricacies of training and excessively concerned with matters such as your form, breathing patterns, and so forth. These factors will tend to slow the pace of your training. Still, it is best to keep your rest intervals close to the suggested limits. Rest longer only if you are feeling dizzy or overworked. Your body will quickly adjust to a fast-paced tempo, and you will soon be able to move from one set to the next without incident.    
       
    Repetitions: The repetition target will be 15 per set. It is essential to train with good form and to apply continuous tension to your muscles during each repetition. Make an effort to develop your mind-to-muscle link early, making each rep count. From the outset, do not fall into the habit of trying to determine where you are feeling muscular stress. This passive attitude indicates that you are not properly visualizing the target muscle. Rather, think about where you are supposed to feel an exercise. Your task is to isolate a muscle or group of muscles, purging all other thoughts. Do not be concerned with your surroundingswhatever might be going on around you is irrelevant. Forget your troubles, your business dealings, your family obligations. Concentrate only on performing each repetition with total focus on your target muscle.    
       
    Intensity: You should perform all sets with a weight that is approximately 75 percent of your maximum poundage. Your maximum poundage is defined as a weight that causes you to reach muscular failure on the 15th repetition. A weight of 75 percent of maximum poundage would normally induce momentary muscular failure at 20 repetitions. For example, let's assume that performing leg extensions with 40 pounds causes you to reach failure on the 15th repetition. In this scenario, your working weight for this exercise would be 30 pounds (40 ´ .75). By your 15th repetition, this weight should begin to feel heavy without causing you to struggle or compromise form to complete the set. As you gain strength, increase the amount of weight to maintain your target of 75 percent of maximum. Moreover, as you gain experience, you can gradually increase the percentage of maximum weight to a point where you begin to approach failure (going as high      as 90 percent of maximum poundage). This can help prepare your body for the intensity required in the next level of training. It is not advisable, though, to attempt to train to absolute failure. Your body is not yet geared for such intense exercise, and you will invariably become overtrained.    
Conditioning Protocols

Number of exercises:1 per muscle group
Number of sets:  3 per exercise
Rest between sets: No more than 30 seconds    
Repetitions per set: 15
 % of maximum weight: 75%
       
    The element in the left margin summarizes the specific protocols of the body-conditioning phase of this system. Follow these protocols rigidly, with little modification. As you become familiar with the training process and progress to the more advanced phases of this system, you will have flexibility to alter the structure of the routine. At this level, however, it is best to keep things simple.    
       
    Using a training diary can help you move smoothly through your routine. A good strategy is to write down in advance the exercises that you will perform. You can then do your workout routine knowing exactly what you are supposed to accomplish in the session. In this way, you won't aimlessly wander around thinking about which exercises to perform. The diary should include the exercises you used in each session, the amount of weight that you used in each set, and any notes that might help you in the future.    
       
    If you have never trained before, or have not trained for some time, consider your first few workouts an acclimation period. The goal should be to adapt your body to the routine and allow it to adjust to the stresses of weight training. Although you are probably already eager to see results, you should approach this phase as if you were about to swim in a cold pool. Obviously, it would be ill advised to dive headfirst into the pool without first testing the water! Your body could go into shock from the extreme difference between body temperature and the temperature of the water. Similarly, your muscles, connective tissue, and nervous system will experience shock from the demands of training, making it easy to overtax your body during this fragile period. If you are not careful, you can experience severe soreness, headaches, or injuries from overzealous efforts. These ailments can set back or stop your ability to work outand limit your potential to achieve results. Nothing can derail your workout regimen more than an injury, so use discretion.    
       
    Moreover, conditions related to age can further inhibit initial training efforts. After the age of 35, a woman loses roughly 1 percent of her muscle mass and bone density each year. By age 45, a woman will have lost about 10 percent of her fundamental body mass, by 55, 20 percent, and so on. Because this progression compromises strength and endurance, your capacity to train at an intense level will, at first, be hampered. Consequently, the older you are, the more careful you should be to acclimate your body during the initial stages of training. Although you can reverse the effects of aging, it will take time and a dose of patience.    
       
    To acclimate your body, you should use only 50 percent of your maximum weight during your first training session. In each successive workout, you can gradually increase the poundage until you reach your target weight. Determining your starting weight requires you to estimate your initial strength level, but without physically training to failure, you can only make an educated guess of your lifting abilities. To prevent injury, err on the side of caution and choose a      weight that is too light rather than too heavy. Remember, this is only an acclimation period, and you need not push hard. You will soon be able to gauge your strength and know beforehand the weight required for a particular exercise.    
       
    Even with proper acclimation, you should expect to feel a degree of muscular soreness. This is especially prevalent in the first few weeks of training, but you will experience this malady even after becoming an accomplished trainee. Although the pain should not be severe, you should feel tenderness and sensitivity in the muscles that you trained. Unfortunately, soreness is a necessary by-product of the training process. It arises from microscopic tears that occur from the stress of weight training, which subsequently cause internal swelling in your muscles and connective tissue. Usually, the soreness will last several days and slowly subside as your body initiates the healing process. This is an indication that your body is adapting to the demands of exercise and preparing itself for the next training session.    
       
    It is important that you not let muscular soreness inhibit or deter your training efforts. Working out during periods of mild soreness can help assuage the associated pain and discomfort. Training aids the circulation of blood flow through your muscles and connective tissue, which can accelerate recuperation. If you are extremely uncomfortable and simply cannot train, take a few days off and use soothing remedies such as whirlpool baths to alleviate the soreness. Try not to stay completely sedentary, though; even mild activity can increase circulation to body tissue and accelerate the healing process. Of course, if you experience any sharp pain, stop training immediately and seek the advice of a physician.    
       
    During the initial four- to six-week training period, you should employ compound movements whenever possible. As previously discussed, compound movements will stimulate the greatest amount of muscle fibers, as well as strengthen your connective tissue and orient your nervous system to the demands of weight training. This will help you achieve balanced development from the outset and negate the possibility of developing muscular deficiencies as you progress in your endeavors. The many variations of compound exercises permit you to add variety to your training and still meet this directive.    
       
    Table 3.1 details a three-day sample routine that you might use in the first four to six weeks of your routine. These routines, like all the sample routines in this book, are only a guide to the possibilities of creating a diversified workout. A multitude of combinations is available for you to explore. Varying your routine will optimize results and help prevent boredom.    

Table 3.1 Conditioning Program Three-Day Sample Routine
Muscle group   
      Day 1             Day 2        Day 3       

Chest     Incline dumbbell    presses    Machine chest presses    Push-ups
Back    Front lat pulldowns    Seated rows    One-arm dumbbell rows
Shoulders    Military presses    Arnold presses    Upright rows
Biceps    Seated dumbbell cruls    Cable curls    EZ curls
Triceps    Nosebreakers    Pushdowns    Close-grip bench presses
Quadriceps    Leg presses    Squats    Lunges
Hamstrings and glutes    Good mornings    Stiff-legged deadlifs    Hyperextensions
Calves    Seated calf raises    Donkey calf raises    Standing calf raises
Abdominals    Crunches    Bench leg raises    Knee-ins

       
       
    It is important to note the order of the exercises and how they relate to each muscle group. In the beginning stages of training, it is best to train large muscle groups first in your routine. Although it does not really matter whether you train your upper or lower body first, you should train the muscles of the torso (chest, back, and shoulders) before the arms (biceps and triceps) and the muscles of the quadriceps before the hamstrings. If you train smaller muscles first, they will be less able to serve as secondary muscle movers in exercises for the larger muscle groups. Ultimately, your secondary muscles will fatigue before your primary muscles, and you will not achieve maximal stimulation of the target muscle. For instance, performing a barbell curl will exhaust your biceps. If you then perform a seated row, your biceps will tend to give out before you fully stimulate the muscles of your back, thereby decreasing the effectiveness of the exercise.    
       
    Moreover, when training the upper body, it is best to alternate between pushing and pulling movements. The chest, shoulders, and triceps are used to push a weight, while the back and biceps are pulling mechanisms. Alternating these movements allows several minutes for the antagonist muscle to rest, thereby improving energy resources for exercise performance. Notice in the sample routine that you train first the chest (which uses the shoulders and triceps as secondary muscle movers), next the back (which uses the biceps), then the shoulders (which use the triceps), and finally the biceps and triceps. In this way, you maximize muscular recovery between each exercise.    
       
    After the initial four- to six-week acclimation phase, you should begin to incorporate isolation movements into your routine. Experiment with different exercises, paying close attention to the unique qualities of each movement. Make sure, though, that you do not neglect to include compound movements in your workout. These staple exercises, because of their all-encompassing effect, have great utility for beginners. Mixing a variety of compound and isolation movements into your workout will serve as a precursor to the next level of training, in which you will use a split routine.    
       
    Table 3.2 shows a three-day sample routine that expands on the initial routine by combining a variety of compound and isolation movements. You should now be comfortable with the structure of this routine and should work on perfecting what you have learned. Again, be creative and do not be afraid to try new exercises. This will not only provide stress to a maximum number of muscle fibers but also hone your performance skills for future gain.    


Table 3.2 Three-Day Routine With Compound and Isolation
Movements
Muscle group           Day 1          Day 2                  Day 3
Chest                    Pec decks    Flat dummbell      Flat bench flys
                                                   presses   
Back         Reverse lat pulldowns    One-arm seated rows Straight-arm pulldowns
Shoulders         Shoulder presses    Lateral raises    Bent lateral raises
Biceps              Preacher curls    Incline curls    Concentration curls
Triceps            Triceps kickbacks    Triceps dips    Overhead extensions
Quardriceps      Leg extensions    Hack squats    Front squats
Hamstrings and glutes    Lying leg curls    Abductor pulls    Seated leg curls
Calves                 Seated calf raises    Toe presses    Donkey calf raises
Abdominals         Rope crunches    Hanging leg raises    Twisting crunches



     When executing unilateral movements (in which you train one arm or leg at a time), it is best to avoid resting between sets. In the one-arm dumbbell row, for      instance, you should start with one arm, perform 15 repetitions, go to the other arm, perform 15 repetitions, and repeat this process without rest. Thus, one side will be able to recuperate while you use the other for performance of the movement. By the time that you have completed 15 repetitions on one side, your alternate side should be fully recovered and ready to continue with the set. Because your body is never totally at rest, you will be able to maintain an accelerated heart rate, increasing your body's ability to burn fat.    
       
    As you try different exercises, you will probably find some movements uncomfortable or awkward to perform. There may be several causes for this. Sometimes, even after repeated attempts, an exercise will just not feel right to you. If this is the case, simply drop it from your routine and move on to a complementary movement. There is no reason to keep the exercise in your training arsenal. You may decide, however, to try the exercise again after you have further developed your strength and motor skills. Often, you ultimately will find the movement to be natural and realize additional benefits from added variety.    
       
    You might wonder what to do if you are not able to perform a complete set of 15 repetitions of a particular exercise. In most cases, you should be able to decrease the weight enough so that you can achieve your target rep number. But you will probably come upon an exercise that, no matter how hard you try, will defeat your effort to finish an entire set. This may especially be true in abdominal exercises and other body-weight-influenced movements, in which your own weight will affect your strength capabilities. If you just cannot attain 15 reps for a given set, perform as many repetitions as you can until your body gives out. Fortunately, strength and endurance tend to build up quickly, and you will see rapid improvement in these areas. With continued effort, you should be able to achieve your target repetition number on virtually any exercise.

Once you have used the body-conditioning routine for a while, you will probably reach a point where you feel that you are ready to advance to a higher level. Understand, though, that taking the next step involves a significant increase in discipline and intensity. Each subsequent level of training requires a greater amount of effort. You therefore must use discretion in going forward. You may then wonder How do I know when I am ready to take the next step? In truth, there is no certain answer. Before you continue, however, you should consider these points:    
       
    Make sure that you are knowledgeable about the basic principles of exercise. The mental aspects of training become increasingly important as you climb the ladder in your fitness endeavors. Understanding these principles will be crucial in maximizing results at the next level of training. Make sure that you are clear on each principle and understand how they apply to the training process.    
       
    Make sure that you are comfortable with a variety of compound and isolation exercises. You should be able to perform dozens of exercises and be able to move easily from one to the next. Moreover, you should have a good grasp of exercise form and function and know the muscles that each exercise will target. In the next level of training, this knowledge will allow you to combine these movements to mesh synergistically with one another.    
       
    Make sure that you are willing and able to increase your exercise intensity. It is one thing to want to train on a more advanced basis; it is another to endure the intensity required for this progression. Many women do not realize the increased effort required to train at the next level. The body-conditioning routine is preparation for developing overall intensity. You should gauge your ability to progress based on the difficulty you have with this routine.    
       
    If you are still not proficient or capable in any of these areas, take more time to develop your skills and mental acuity. Work on the basics, preparing your mind and body for more intense training. Do not pressure yourself to advance to the next phase. In fact, if you are happy with the way that you look at this point, you can continue with the body-conditioning phase indefinitely. Many women do not aspire, or are not willing, to train at a higher pace and are content with maintaining the status quo. This routine, however, will not advance you to your genetic potential. Therefore, if you want to take the next step and begin the process of bodysculpting, advance to chapter 4 and read on.

What do you think about Physiotherapists ??????


Physiotherapists work to prevent, rehabilitate and treat movement disorders. In order to do this they work with those parts of the body that are involved in movement: muscles, tendons, joints, the nervous system, the circulatory system, and respiration.
The mentally ill can also benefit from physiotherapy. One of the cornerstones of physiotherapy is the integrated nature of body and mind. Working with physical aspects will thus influence perceptual, intellectual and emotional aspects.

Physiotherapy is practised at all hospitals  both in physiotherapy departments and in other wards

On a local level physiotherapy treatment is offered at institutions for children, for the elderly, and for the handicapped. In the case of special needs, treatment can be offered at home.

Physiotherapy clinics offer treatment, prophylactic training and rehabilitation on an outpatient basis following referral from a doctor.

Some examples of the methods a physiotherapist can use: coordination training, fitness and endurance training, stretching, muscle strengthening, massage, joint mobilisation, treatment with various electrical devices, instruction in ergonomics, body-awareness training, breathing exercises, instruction concerning the need for and use of aids, and general as well as specific consultation

Nobel prize for medicine - for father of in-vitro fertilisation (IVF)

Nobel Prize in Physiology or Medicine 2010 Was Awarded to Robert G. Edwards for IVF Fertilization

ScienceDaily (Oct. 4, 2010)

Robert Edwards has been awarded the 2010 Nobel Prize for the development of human in vitro fertilization (IVF) therapy. His achievements have made it possible to treat infertility, a medical condition afflicting a large proportion of humanity including more than 10% of all couples worldwide.

As early as the 1950s, Edwards had the vision that IVF could be useful as a treatment for infertility. He worked systematically to realize his goal, discovered important principles for human fertilization, and succeeded in accomplishing fertilization of human egg cells in test tubes (or more precisely, cell culture dishes). His efforts were finally crowned by success on 25 July, 1978, when the world's first "test tube baby" was born. During the following years, Edwards and his co-workers refined IVF technology and shared it with colleagues around the world.
Approximately four million individuals have so far been born following IVF. Many of them are now adult and some have already become parents. A new field of medicine has emerged, with Robert Edwards leading the process all the way from the fundamental discoveries to the current, successful IVF therapy. His contributions represent a milestone in the development of modern medicine.
Infertility -- a medical and psychological problem
More than 10% of all couples worldwide are infertile. For many of them, this is a great disappointment and for some causes lifelong psychological trauma. Medicine has had limited opportunities to help these individuals in the past. Today, the situation is entirely different. In vitro fertilization (IVF) is an established therapy when sperm and egg cannot meet inside the body.
Basic research bears fruit
The British scientist Robert Edwards began his fundamental research on the biology of fertilization in the 1950s. He soon realized that fertilization outside the body could represent a possible treatment of infertility. Other scientists had shown that egg cells from rabbits could be fertilized in test tubes when sperm was added, giving rise to offspring. Edwards decided to investigate if similar methods could be used to fertilize human egg cells.
It turned out that human eggs have an entirely different life cycle than those of rabbits. In a series of experimental studies conducted together with several different co-workers, Edwards made a number of fundamental discoveries. He clarified how human eggs mature, how different hormones regulate their maturation, and at which time point the eggs are susceptible to the fertilizing sperm. He also determined the conditions under which sperm is activated and has the capacity to fertilize the egg. In 1969, his efforts met with success when, for the first time, a human egg was fertilized in a test tube.
In spite of this success, a major problem remained. The fertilized egg did not develop beyond a single cell division. Edwards suspected that eggs that had matured in the ovaries before they were removed for IVF would function better, and looked for possible ways to obtain such eggs in a safe way.
From experiment to clinical medicine
Edwards contacted the gynecologist Patrick Steptoe. He became the clinician who, together with Edwards, developed IVF from experiment to practical medicine. Steptoe was one of the pioneers in laparoscopy, a technique that was new and controversial at the time. It allows inspection of the ovaries through an optical instrument. Steptoe used the laparoscope to remove eggs from the ovaries and Edwards put the eggs in cell culture and added sperm. The fertilized egg cells now divided several times and formed early embryos, 8 cells in size.
These early studies were promising but the Medical Research Council decided not to fund a continuation of the project. However, a private donation allowed the work to continue. The research also became the topic of a lively ethical debate that was initiated by Edwards himself. Several religious leaders, ethicists, and scientists demanded that the project be stopped, while others gave it their support.
The birth of Louise Brown -- an historic event
Edwards and Steptoe could continue their research thanks to the new donation. By analyzing the patients' hormone levels, they could determine the best time point for fertilization and maximize the chances for success. In 1978, Lesley and John Brown came to the clinic after nine years of failed attempts to have a child. IVF treatment was carried out, and when the fertilized egg had developed into an embryo with 8 cells, it was returned to Mrs. Brown. A healthy baby, Louise Brown, was born through Caesarian section after a full-term pregnancy, on 25 July, 1978. IVF had moved from vision to reality and a new era in medicine had begun.
IVF is refined and spreads around the world
Edwards and Steptoe established the Bourn Hall Clinic in Cambridge, the world's first centre for IVF therapy. Steptoe was its medical director until his death in 1988, and Edwards was its head of research until his retirement. Gynecologists and cell biologists from all around the world trained at Bourn Hall, where the methods of IVF were continuously refined. By 1986, 1,000 children had already been born following IVF at Bourn Hall, representing approximately half of all children born after IVF in the world at that time.
Today, IVF is an established therapy throughout the world. It has undergone several important improvements. For example, single sperm can be microinjected directly into the egg cell in the culture dish. This method has improved the treatment of male infertility by IVF. Furthermore, mature eggs suitable for IVF can be identified by ultrasound and removed with a fine syringe rather than through the laparoscope.
IVF is a safe and effective therapy. 20-30% of fertilized eggs lead to the birth of a child. Complications include premature births but are very rare, particularly when one egg only is inserted into the mother. Long-term follow-up studies have shown that IVF children are as healthy as other children.
Approximately four million individuals have been born thanks to IVF. Louise Brown and several other IVF children have given birth to children themselves; this is probably the best evidence for the safety and success of IVF therapy. Today, Robert Edwards' vision is a reality and brings joy to infertile people all over the world.

Sweden's Karolinska Institute lauded Edwards, 85, for bringing joy to infertile people all over the world.
Known as the father of in-vitro fertilisation (IVF), Edwards picked up the prize of 10 million Swedish crowns ($1.5 million) for a "milestone in the development of modern medicine", the institute said.

Physical activity

Physical activity



Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure.
Physical inactivity (lack of physical activity) has been identified as the fourth leading risk factor for global mortality (6% of deaths globally). Moreover, physical inactivity is estimated to be the main cause for approximately 21–25% of breast and colon cancers, 27% of diabetes and approximately 30% of ischaemic heart disease burden.
Regular and adequate levels of physical activity in adults:
  • reduce the risk of hypertension, coronary heart disease, stroke, diabetes, breast and colon cancer, depression and the risk of falls;
  • improve bone and functional health; and
  • are a key determinant of energy expenditure, and thus fundamental to energy balance and weight control.
The recommended levels of physical activity for health benefits and prevention of noncommunicable diseases are available for download here.http://whqlibdoc.who.int/publications/2010/9789241599979_eng.pdf
The term "physical activity" should not be mistaken with "exercise". Exercise, is a subcategory of physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components of physical fitness is the objective. Physical activity includes exercise as well as other activities which involve bodily movement and are done as part of playing, working, active transportation, house chores and recreational activities.
Increasing physical activity is a societal, not just an individual problem. Therefore it demands a population-based, multi-sectoral, multi-disciplinary, and culturally relevant approach.

Age group: 5-17 Years old

For children and young people, physical activity includes play,games, sports, transportation, chores, recreation, physical education, or planned exercise, in the context of family, school, and community activities. In order to improve cardiorespiratory and muscular fitness, bone health, and cardiovascular and metabolic health biomarkers:
  • Children and youth aged 5–17 should accumulate at least 60 minutes of moderate- to vigorous-intensity physical activity daily.
  • Amounts of physical activity greater than 60 minutes provide additional health benefits.
  • Most of the daily physical activity should be aerobic. Vigorous-intensity activities should be incorporated, including those that strengthen muscle and bone, at least 3 times per week.
More information about Physical Activity in Young People

Age group: 18-64 years old

 

In adults aged 18–64, physical activity includes leisure time physical activity, transportation (e.g. walking or cycling), occupational (i.e. work), household chores, play, games, sports or planned exercise, in the context of daily, family, and community activities. In order to improve cardiorespiratory and muscular fitness, bone health, reduce the risk of NCDs and depression:
  • Adults aged 18–64 should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
  • Aerobic activity should be performed in bouts of at least 10 minutes duration.
  • For additional health benefits, adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity activity.
  • Muscle-strengthening activities should be done involving major muscle groups on 2 or more days a week.
More information about Physical Activity in Adults


Age group: 65 years old and above

In older adults aged 65 years and above, physical activity includes leisure time physical activity, transportation (e.g. walking or cycling), occupational (if the individual is still engaged in work), household chores, play, games, sports or planned exercise, in the context of daily, family, and community activities. In order to improve cardiorespiratory and muscular fitness, bone and functional health, reduce the risk of NCDs, depression and cognitive decline:
  • Older adults should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
  • Aerobic activity should be performed in bouts of at least 10 minutes duration.
  • For additional health benefits, older adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate-and vigorous-intensity activity.
  • Older adults, with poor mobility, should perform physical activity to enhance balance and prevent falls on 3 or more days per week.
  • Muscle-strengthening activities, involving major muscle groups, should be done on 2 or more days a week.
  • When older adults cannot do the recommended amounts of physical activity due to health conditions, they should be as physically active as their abilities and conditions allow.

Facts on physical activity

The concept of physical activity covers all forms of muscular work which boosts energy conversion. Exercise covers both unstructured activity and more conscious, targeted and regular training. Here, the concepts physical activity and exercise are used synonymously. Training is planned, structured physical activity which is performed regularly to maintain and/or improve your physical condition and sense of well-being. In contrast, inactivity describes a life without any movement. Inactive people are not physically active in any way and engage in neither structured nor structured physical activities.

Effect of physical activity Current research into the effects of physical activity on the body shows that:
  • People who are normally inactive can improve their health and physical well-being by engaging in regular exercise. 
  • People of all ages – children, adults, older people, women and men – all benefit physiologically from physical activity. 
  • Physical activity does not have to be exhausting for it to benefit your health. 
  • Physical activity has many positive effects on the bodily functions. Its effect on the heart, circulation and muscles has been recognised for many years. However, it is also worth noting the positive effect of exercise on your metabolism and on the hormone and immune systems. 
  • Many of the positive effects of physical activity – both from endurance training and from muscle-strengthening exercise – diminish after a few weeks. If you stop being active altogether, the effect disappears completely within 2-8 months. 
  • Physical activity leads to socio-psychological benefits in the form of feeling happy about life, higher energy levels, social well-being, self-confidence and decisiveness. Moreover, it has been demonstrated that there is a positive connection between physical activity and cognitive processes which are necessary for children's learning.

Why 30/60 minutes?

Regular physical activity can help to keep your body fit and healthy and prevent a number of illnesses and ailments.
Physical activity prevents the following lifestyle and widespread chronic diseases:
  • Circulatory diseases (cardiovascular diseases, raised cholesterol, triglyceride and blood pressure levels, overweight, obesity, insulin resistance and type II diabetes) 
  • Stress 
  • Muscular and skeletal illnesses 
  • Certain cancers (colon cancer and breast cancer) 
  • Mental illnesses (depression, anxiety and dementia) 
  • Osteoporosis

Physical activity improves your health:
  • Helps to reduce blood pressure for people who already have high blood pressure
  • Helps control weight
  • Helps older people become stronger and better able to move about without falling over
  • Improves mental and social well-being, including feeling happy about life, energy levels, social well-being, self-confidence and decisiveness
  • Regular physical activity can prevent the above diseases while promoting the beneficial conditions

If you already suffer from one of the above illnesses, physical activity can help reduce the risk of the illness developing or your condition deteriorating.

Recommendations for the overweight

  • All overweight and obese people must engage in moderate-intensity physical activity for at least 30 minutes, ideally seven days a week. The 30 minutes can be split into shorter periods, for example 15 minutes in the morning and 15 minutes later, or three 10-minute periods in the course of the day.

  • If you want to lose weight, the Danish National Board of Health recommends a combination of regular physical activity and reducing the number of calories you consume.

Preventing overweight and obesity
Physical inactivity increases the risk of becoming overweight and obese, which has further implications for your health. You can prevent a number of lifestyle diseases related to overweight and obesity by following the Board's recommendations regarding physical activity. The effect is greatest if you combine physical activity with lower calorie consumption. Physical activity prevents the following conditions which can be triggered by overweight and obesity:
  • Type 2 diabetes (improving the insulin effect)
  • Dyslipidemia (elevated concentration of triglyceride and cholesterol in the blood)
  • Raised blood pressure

Physical activity for pregnancy

Physical exercise during pregnancy is beneficial for both mother and child, and there are only a few important precautions. Several studies have shown that women who are physically active before they become pregnant can certainly continue being active while pregnant, as long as they feel comfortable. Pregnant women who have not previously been physically active can benefit from being physically active and taking exercise while pregnant.
Physical activity covers all forms of movement which boosts energy conversion. Examples include moving at work and around your home, active transport (e.g. cycling and walking) or athletics and sport in your leisure time etc.

Physical activity when pregnantThe Danish National Board of Health recommends that pregnant women engage in moderate-intensity exercise for at least 30 minutes a day. The 30 minutes can be split into shorter periods, for example 15 minutes in the morning and 15 minutes later, or three 10-minute periods in the course of the day.
What is moderate-intensity exercise tip

Physical activity which is not recommended when pregnant
Contact sports and team sports which involve a risk of collision with fellow players and/or opponents are not recommended for pregnant women as there is considerable risk of unexpected jolts. Likewise, skiing and riding should be avoided as falls can lead to serious injury. Suitable forms of physical exercise include walking and hiking, swimming, running, muscle-strengthening exercises (in a seated position and not heavy weight training), cycling, spinning, aerobics etc.
Pregnant women are advised not to engage in high-intensity physical activity where their blood circulation is pushed to the limit if they have not engaged in high-intensity exercise prior to becoming pregnant. Pregnant women who are used to high-intensity exercise are advised not to do long-distance running and other fatiguing activities, and to refrain from intensifying their training while pregnant. Moreover, pregnant women are advised to listen carefully to their bodies if they engage in high-intensity physical exercise. Respect pain.

Older people and physical activity

Recommendations for older people

  • The Danish National Board of Health recommends that older people, like younger adults, spend at least 30 minutes a day engaged in moderate-intensity physical activity.

What is moderate-intensity physical activity? Moderate-intensity physical activity involves all types of activity/exercise which increase the pulse rate, and where you can continue talking at the same time. Examples of moderate-intensity physical exercise: cycling and walking to and from the supermarket, gardening, walking up and down stairs, going jogging and other types of exercise. The bottom limit for moderate-intensity physical exercise corresponds to walking at an average speed of 4 km/h.
Many of the problems faced by older people in their daily lives can be prevented through physical activity.

The benefits of being physically active are:
  • less risk of falling ill
  • improved quality of life
  • less risk of falling over
  • longer life-span

Older people can benefit further by:
  • performing activities at least twice a week which maintain or increase their muscle strength and fitness
  • being physically active in ways that exercise their sense of balance
  • maintaining their mobility by performing stretching exercises

    Physical activity and energy consumption

    Increased physical activity in connection with daily activities can lead to increased energy consumption. The table shows how much energy you normally burn when performing various activities.
    It is important to emphasize that increased energy consumption does not necessarily lead to weight loss. Being active can reduce the amount of fat on your body, but it can also result in more muscle mass – in which case the scales show the same weight. An important aspect of exercising is, also in relation to weight regulation that it helps to restore and maintain balance within the body, benefiting your appetite and metabolism. From a health point of view, it is better to be physically active and weigh a couple of kilogrammes too much than being slim and physically inactive.

    Exercise your Shoulder Pain Free

    What Causes Shoulder Pain?
    Many of us will experience shoulder pain at some point in our lives, and it is a
    very common problem. It is vital to accurately diagnose the pain so the shoulder
    can be rehabilitated and treated as soon as possible. Here are some of the more
    common causes of shoulder pain, with a brief explanation of each cause.
    The following conditions are treatable using my book:
    Shoulder impingement syndrome – this is where the supraspinatus tendon
    (one of the rotator cuff muscles) gets trapped underneath the acromioclavicular
    joint (ACJ). Other names for shoulder impingement syndrome are clinical
    impingement syndrome and painful arc syndrome.
    Bursitis – inflammation of the bursa (fluid filled sac) that sits underneath one of
    the shoulder joints, known as the acromioclavicular joint.
    Supraspinatus tendonitis – this is tendonitis of the supraspinatus muscle, one
    of the rotator cuff muscles. Most often caused by abrasion underneath the ACJ.
    Rotator Cuff Tear – this is where one of the rotator cuff muscles tears. You may
    suffer a full thickness tear, or a partial thickness tear. The rotator cuff attach all
    around the shoulder and help to stabilise it.
    Calcific tendonitis – this is where the rotator cuff tendon becomes calcified due
    to a prolonged period of abrasion.
    Shoulder Arthritis (of the acromioclavicular joint) – wear and tear changes
    under the acromion of the shoulder leading to shoulder impingement syndrome.
    This includes bone spurs.
    Frozen shoulder – also known as adhesive capsulitis, this is where the shoulder
    joint capsule hardens usually in response to trauma or surgery. This results in a
    widespread stiffening of the shoulder. Commonly over-diagnosed.
    Shoulder Dislocation – the arm bone (humerus) is forced out of the shoulder
    joint, usually by trauma.
    Shoulder instability – a loose shoulder joint which usually results after dislocation.
    Acromioclavicular (AC) Dislocation – the clavicle (collar bone) is forced out of
    joint. Usually results from a fall on an outstretched hand.
    Labral tear – the rim of the shoulder joint is torn during trauma. Most common in
    contact sports such as rugby.
    Shoulder Arthritis (of the glenohumeral joint) – degeneration of the head of the
    humerus.
    Biceps Tendon rupture – the biceps (upper arm muscle with two heads) tendon
    pulls off the bone as a result of trauma.

    Exercises
    I have categorised these exercises in levels 1 – 4. You should perform the levels
    in order, and only progress to the next level when you have achieved the
    previous level.
    In the photographs, Jon has a painful RIGHT shoulder.
    You may use the periodisation table in the appendix as a guide to likely time frames
    of shoulder exercise progression, but don’t be tempted to rush ahead. Go
    at your own pace, and perform the exercises gently and as described.

    Level 1 Exercises – Passive Mobilisation:
    Level 1 is designed to improve the range of mobility in your stiff shoulder.
    Perhaps you want to read that again! Yes, these exercises will finally allow you to
    move your arm in a comfortable range of mobility. Great for any stiff shoulder.
    The exercises start assisted, so the muscles of the painful shoulder can remain
    relaxed while the shoulder is mobilised. We call these passive range of mobility
    exercises. Alternatively at this point, if you have a good osteopath or
    physiotherapist, they can assist by lifting your arm for you.
    When you do these exercises, move the joint slowly, and gently. Avoid the ranges
    of movement that give you sharp pain, although feeling minor discomfort should
    be expected in certain ranges.
    Take the shoulder to the point of mobility which feels comfortable, and then take
    it just a fraction further to increase the range of motion. At this point, return the
    arm to its resting position.
    You will find that every couple of days you will notice some improvement in the
    range of mobility of that shoulder and arm. You can compare the movement to
    that of the good shoulder to give you an indication of how far you have to go with
    the mobility.


    1. The Pendulum
    • Keep the shoulder completely relaxed
    • Let momentum and gravity move it in circles
    • Go anti-clockwise and clockwise
    • Keep the circles within your comfort zone
    • Perform for 2 minutes, 3x per day

    2. Rock the baby
    • Keep the bad arm relaxed…
    • The good arm holds the bad arm
    • Keep the movement within your comfort zone
    • Rock 15x each side, 3x per day

    3. Passive flexion
    • The affected shoulder should be relaxed during the movement
    • The left arm lifts the right arm
    • Keep the movement within your comfort zone
    • Perform 15 repetitions, 3x per day.

    4. Passive extension
    • The right arm stays relaxed during the movement
    • The left arm pushes the right arm backwards
    • Keep the movement within your comfort zone
    • Perform 15 repetitions, 3x per day.

    5. Passive abduction 30°
    • The right arm stays relaxed during the movement
    • The left arm lifts the right arm
    • Make sure the arm is lifted at 30°
    • Perform 15 repetitions, 3x per day

    6. Towel exercise for internal rotation
    • The active arm is the left arm, the right arm stays completely
    relaxed except to hold the towel
    • Straighten the left arm, thus allowing the right arm to come up
    the back
    • Move up and down within your comfort zone
    • Perform 15 repetitions, 3x per day

    Level 2 Exercises – Stabilisation:

    1. Sitting stabilisation
    • Sit on a bench or chair
    • Rest your hands by your side
    • Gently lean from one hand to the other hand, putting gentle but
    increasing weight through the shoulder
    • Do not put all your weight through the right shoulder, just lean
    into it
    • Rock 15x onto the right shoulder, 3x per day.

    2. Standing stabilisation
    • Start around 1½ feet from a wall
    • Lean forwards onto the wall, resting the palms flat against the
    wall with the elbows bent (in a standing press-up position)
    • Rock gently from side to side, applying pressure to one shoulder
    and then the other.
    • You can make the exercise more challenging by moving the feet
    further away from the wall.
    • Hold for 30 seconds, 3x per day

    3. Stabilisation in 4 point kneeling
    • Start in a 4 point kneeling position
    • Rock gently from side to side, applying pressure to one shoulder
    and then the other.
    • Hold for 30 seconds, 3x per day


    Level 3 Exercises: Active Mobilisation:

    Level 2 exercises are a natural progression from level 1, because they now rely
    on your shoulder muscles to move the joint.
    Again, work within your comfort zone… don’t push the shoulder through the pain
    barrier. Take it to its comfortable end of range, and then just a fraction further to
    get the required mobility.

    1. Side-Arm pendulum
    • Swing the arm in a pendulum as shown
    • Go clockwise and counter-clockwise
    • Perform for 30 seconds, 3x per day

    2. Shoulder shrugs
    • Upwards: lift the shoulders towards the ceiling, and hold for a
    couple of seconds, before relaxing.
    • Backwards: pull the shoulders backwards by squeezing the
    shoulder blades, and hold for a couple of seconds before
    relaxing.
    • Perform 10 repetitions, 3x per day.

    3. Chicken wings
    • Resting the hands on the hips, pull the shoulders backwards
    and forwards
    • Perform 10 repetitions, 3x per day

    4. Flexion
    • Raise your bad arm as far as is comfortable, then try and take it
    just a fraction further
    • Hold for a couple of seconds, then lower.
    • Perform 10 repetitions, 3x per day

    5. Internal rotation “The Brastrap Exercise”
    • Reach behind your back, and take the hand as high up the back
    as comfortable, then just a fraction further.
    • You should feel a gentle pulling feeling at the front of the
    shoulder. Hold this position for a couple of seconds
    • At first you may find this exercise difficult and uncomfortable,
    but persevere, and over a few days you will achieve greater
    mobility
    • Perform 10 repetitions, 3x per day

    6. Stroke the shoulder blade
    • Reach behind the opposite/good shoulder and try to stroke the
    shoulder blade.
    • This is another movement that is likely to be quite painful, but
    again keep practising; go to your end of comfort zone, and just
    a fraction further.
    • Perform 10 repetitions, 3x per day

    7. 30° wall crawl
    • Make sure the arm is not directly to your side
    • Leave it at a 30° angle, as shown in the picture
    • Crawl up the wall to your end of comfortable range, then just a
    fraction further, and back down the wall.
    • Perform 10 repetitions, 3x per day

    8. The Drawing of the Sword
    • The thumb starts facing downwards, and at the end of the
    movement, faces upwards
    • Imagine you are drawing a sword out of its sheath
    • Perform 10 repetitions, 3x per day

    9. Pec Stretch
    • A lovely shoulder exercise, great for posture; it will improve
    mobility in the anterior capsule of the shoulder
    • Rotate the torso, and lean forward, creating a stretch to the
    shoulder
    • Perform 10 repetitions, 3x per day

    10. The Football Supporter
    • One of my favourites, but the hardest in this level, so don’t do it
    unless you feel comfortable with it
    • Holding a towel above your head (imagine it’s a scarf of your
    favourite football team), gently move the arms from side to side
    • Perform 10 repetitions, 3x per day

    Level 4 Exercises: Advanced Stabilisation

    1. Swiss Ball Stabilisation 2 hands
    • Kneel down, place the hands on a Swiss ball
    • The instability of the ball will help the small stabiliser muscles of
    the shoulder strengthen
    • Progress the exercise by moving the knees further from the ball
    • Hold for 30 seconds, 3x per day
    • Increase the hold for up to 2 minutes as you get stronger

    2. Swiss Ball Stabilisation 1 hand
    • The same exercise as the previous, but one handed
    • Hold for 30 seconds, 3x per day
    • Increase the hold for up to 2 minutes as you get stronger

    3. 2-point Kneeling
    • Adopt a 4-point kneeling position
    • Lift opposite arm and leg 2 inches from the floor, so that your
    weight is put through the bad shoulder
    • Hold for 30 seconds, 3x per day
    • Increase the hold for up to 2 minutes as you get stronger

    4. Prone Cobra
    • This is a great exercise for scapular stability, and back extensor
    strength, helping to keep those shoulders back, thus helping to put the
    shoulder in a mechanically advantageous position
    • Make sure the thumbs are facing upwards, with the arms turning
    outwards (n.b. not inwards). You will notice that turning the arms
    outwards opens the chest and shoulders (=good), inwards closes the
    chest and shoulders (=bad)
    • Hold for 30 seconds, 3x per day
    • Increase the hold for up to 2 minutes as you get stronger

    Self-treatment system has got bad knees taped

    By Derek Mortimer
    March 18, 2004

    A simple and inexpensive self-treating program involving the application of tape can provide pain relief and increase mobility for the thousands of people who suffer from osteoarthritis of the knees, a new Australian study has found.
    The taping, which can be taught by a physiotherapist in one or two visits, is combined with muscle-strengthening exercises.
    The treatment involves taping the patella, or knee cap, which must be held in the correct position as it moves over the knee joint, and taping below the knee cap to take pressure off the fatty tissue. It involves two types of tape: a stretchable under-tape to prevent irritation of the skin, and a rigid sports tape. Both varieties are available from most chemists.
    Osteoarthritis of the knees is one of the most common and debilitating diseases of ageing; more than 1 million Australians suffer from it. This number is increasing by about 8 per cent a year.
    The World Health Organisation reports that 40 per cent of people over the age of 70 suffer osteoarthritis of the knees and that globally, osteoarthritis ranks fourth in women and eighth for men in terms of disease impact.
    Osteoarthritis usually develops from 45 years of age onwards, and all forms of arthritis are increasing, says the Arthritis Foundation of NSW.
    The finding on taping follows a study by physiotherapists from the University of Melbourne and claims to provide the first evidence of the effects of knee-taping in the treatment and management of osteoarthritis.
    The randomised, blind-control trial involved 87 patients divided into three groups. One group received no taping, a second received placebo taping and the third received therapeutic taping.
    The taping covered three weeks, with the the tape being replaced at the ends of the first and second weeks. The patients were then assessed three weeks after the tape was removed. The therapeutic tape group reported a decrease in pain of 38 to 40 per cent.
    Dr Kim Bennell, associate professor and director of the Centre for Health Exercise and Sports Medicine at the University of Melbourne, says taping had previously been associated with younger people suffering patellofemoral (front of the knee) pain, generally caused by sporting activity.
    She stressed that taping was one part of self-management and treatment of osteoarthritis, and was best combined with exercises to strengthen the quadriceps muscles and improve balance.
    The exercises include step-ups, partial squats and similar movements that engage specific muscles of the thigh. They can be performed daily or several times a week, depending on the needs of the patient.
    In 1986, Sydney physiotherapist Jenny McConnell pioneered a taping treatment for the management of patellofemoral pain that now bears her name.
    McConnell, who was a member of the research team, says that when treating patients for patellofemoral injuries, she found that not only did the taping reduce that pain, it also reduced osteoarthritic pain in some people.
    In osteoarthritis the pain comes from the soft tissue below the knee cap, rather than the bone, or cartilage, which has no nerves, says McConnell, although there is an association between lack of joint space - a symptom of osteoarthritis - and pain.
    She says taping unloads pressure from the tissue, enabling inflammation to settle down.
    The Australian Institute of Health and Welfare reports that the economic cost of musculoskeletal diseases such as osteoarthritis is $3 billion a year.
    Editor's note: People shouldn't attempt strapping their knees until assessed by a physiotherapist. This treatment is not appropriate for all arthritis sufferers, and in some cases, can cause more pain.
