The effects of exercise on Mental Health

Exercise may be a matter of choice for the normal weight young person who has never had to diet, but for people who are trying to lose weight for life, those who are aging, have risk Factors for or have osteoporosis, are at high risk for cardiovascular disease or diabetes and those who would just like to continue their years with life in them, It is a necessity.

If people lose weight through dieting alone it means that twenty to fifty percent of the weight they dropped was lean body mass (muscle), this muscle mass loss is life threatening if it continues for long amounts of time. Muscle losses occur proportionately from every muscle in their body including their heart, so the longer they stay on a diet, the greater their need for exercise becomes. Yet exercise does more than just protect their muscles it also fights fat and stabilizes their blood sugar level.

After losing weight by caloric restriction alone dieters complain about muscular weakness and flabbiness. This happens because large amounts of muscle tissue have been lost.

Exercise increases the body's capacity to utilize greater amounts of oxygen, which is very important to their overall health. This is especially beneficial to dieters since greater amounts of oxygen allow for a greater expenditure of stored fat, and fat stored in cells inhibits oxygen uptake to obese people. (Pavlou, Constantine and Zak 142)

Exercise also helps slow down the process of aging. Two of the symptoms of aging are changes of body composition and in the persons ability to exercise. Sometimes the changes occur over a period of years and they may not notice them until the problem becomes very obvious. Their body weight will change a considerable amount. Between the ages of thirty and seventy they will gain, on the average between one-half and one pound per year. If they were typical Americans they can expect to weigh forty pounds more at seventy than they did at thirty and the majority of this weight gain is fat. They are gaining this weight because they are exercising less; they ...
