Dr. Ken Cooper, of the Cooper Institute of Aerobic Research, found that exercise was associated with a 40 % reduction in heart attacks in females and a 60 % reduction in heart attacks in males. In another study, he found that people who were in the lower 20 % of cardiovascular fitness had a death rate that was three times higher than the most fit group. The study also showed that men taking up exercise, even after the age of 60, will increase their life expectancy.
Another study of Swedish women demonstrated that mortality was dramatically reduced in women who had physically active jobs or who frequently participated in a leisure-time activity. It was concluded that decreases in physical activity, as well as low initial levels of activity, are strong risk factors for mortality in women, and that their predictive values persist for many years.
Dr. Sherman reported on 1,404 women aged 50 to 74 who were free of cardiovascular disease. The most active group had a 33 % lower death rate than the least active. Therefore, it was concluded that woman who were more active lived longer.
In addition, exercise helps you live longer by reducing your chance of death from causes other than just heart disease. Several studies have shown that colon cancer is reduced 30 % in individuals who exercise regularly. The reason for this reduction is not known. I personally feel it is from improving the function of the immune system. The immune system is greatly affected by stress, and exercise certainly reduces stress. Another advantage of exercise is its positive impact on the treatment of depression. A study published in Sports Medicine found that counseling combined with exercise was more effective than counseling alone.
The Journal of the National Cancer Institute found that the incidence of breast cancer was significantly reduced in females who regularly exercised during the childbearing years.
Osteoporosis can be reduced by working with weights twice a week in post-menopausal women. Exercise increases bone density, and improves strength as well as balance which, in turn can reduce the risk of falls in the elderly. This reduces the mortality rate, since fractured hips are associated with a fairly high death rate.
The JAMA reported that the incidence of gastrointestinal hemorrhage was decreased in elderly people who exercised regularly.
In conclusion, it is apparent that exercise can make you live longer.
Our society has enjoyed a gradually increasing lifespan which I believe
is partially due to the emphasis on exercise in our society over the
past several decades.
