Is exercise bad for you?

Extracts from this document...


Louise Keeley Is exercise bad for you? This piece of coursework is to discuss the possible bad effects of exercise besides the well advertised positive effects. I found that it was extremely difficult to find adverse effects of exercises to be widely published. It is always stated that exercise is a necessity for a healthy and long life in one form or another due to its unlimited benefits. '(1) keeping active helps maintain the capacity to perform activities of daily living and has effects throughout the body. Within the skeleto-muscular system, exercise preserves (and can improve) muscle and bone strength and helps maintain joint flexibility. The increase in venous return to the heart induced by activity stretches the myocardium and causes the heart to contract more forcefully. With regular exercise the heart adapts by strengthening the myocardium; this means that the heart performs less work for any given activity. The increased requirement for oxygen by active muscle cells results in faster and deeper breathing thereby strengthening the respiratory muscles. Activity also promotes peristaltic movements in the digestive tract thereby preventing constipation. In order to gain health benefits, 20-30 minutes of moderate intensity exercise per day (i.e. sufficient to moderately stimulate aerobic respiration) ...read more.


All the risks mentioned are present for each and every exercise for all purposes to some extent, but a more likely in some cases depending on the type of exercise.' Exercise is also known for its vast results with benefiting the aging process and functional capacity. It can increase muscular strength and stamina, increases/maintains bone mineral density preventing osteoporosis, maintains metabolic resting rate to prevent weight gain, improves joint integrity improves balance ad coordination and is even know to reduce the risk of developing colon or breast cancer. For such effects more lifting and movement orientated exercises are needed such as dancing, body building, swimming, etc. Again there are the risks to go with the exercises which could be more destructive with older members of the population. Contusions can occur which are bruises into the muscle tissue, more likely due to the frailness of the tissue, also making strains more likely. Fatigue is possible if the right energy food isn't eaten or if the use of exercise is too intense. Again, due to the age, arthritis and lower back pains would be more likely to be present and therefore call for a great deal more care when exercising. Besides the obvious physical benefits of exercise, it is also known to have various positive effects on the mental health of those who take up some form of exercise. ...read more.


As a bit of a contradiction, a lot the problems I have mentioned as a cause due to exercise to promote both cardiovascular and aging health can also be aided by further exercises. They are obviously less strenuous and more particular to the injured part of the body but are exercises nether the less. In the case of arthritis it is advises to continue with gentle muscle building exercises to try and relieve the weight put onto the swollen, sore joins by building up the muscles to take some of the weight and to protect. For back problems, and during pregnancy, exercises are also advised to build up the muscles to take some of the extra weight, mainly on the lower back. My conclusion to the research I have done and the information that I have collected is that exercise is well worth it if kept to a healthy and safe limit, regardless of the potential risks. Accidents do occur and the other causes of injury indicate that participation should not be taken. I believe the main causes for injury are the methods used to exercise with. Lack of preparation such as inadequate footwear, unsafe terrain, lack of pre-exercise stretching exercises to loosen muscles, etc. are harmful to the body and in my opinion are the cause of most exercise related injury. ...read more.
