A large number of scientific studies and controlled, experimental investigations have demonstrated that adults engaged in physical activity or exercise, as contrasted with their sedentary counterparts, tend to develop and maintain higher levels of physical fitness. Not only has being involved with exercise demonstrated benefits, lack of exercise has shown actual determents! Studies have shown that low levels of habitual physical activity and low levels of physical fitness are associated with markedly increased mortality (death) rates. Even if one was to start an exercise program at mid-life; they have a decreased mortality. It has been estimated that as many as 250,000 deaths per year in the United States, approximately 12% of the total, are attributable to a lack of regular physical activity.
Heart disease is one of the leading killers in our society. Exercise can prevent the occurrence of heart disease and modify its course once it is present. Studies show that exercise training improves all aspects of cardiovascular risk factors including blood lipid profile (cholesterol level), resting blood pressure, body composition, glucose tolerance and insulin sensitivity having to do with the onset and control of diabetes (another major risk factor in heart disease).
High Blood Pressure
High blood pressure or hypertension is a leading risk factor in heart disease, strokes, kidney disease, eye problems, etc. Exercise prevents the onset of hypertension and modifies the treatment of it.
Type II Diabetes Mellitus/Insulin Resistance
Diabetes is a serious cause of health problems ranging from increased heart disease, kidney disease, blindness, vascular complications, neuropathy or loss of sensation and/or increased pain in extremities. Exercise has been shown to prevent this form of diabetes and help control it when present thereby increasing life vitality and expectancy.
Osteoporosis is a degenerative disease of bones. It causes increased risk for fracture, disability and chronic pain syndromes. It affects activities of daily living and is related to increased mortality due to fractures and related complications. Exercise can prevent its occurrence, increase the density of bone, and reduce the risk of fractures.
Even cancer is affected by exercise.
Exercise decreases the risk of colon cancer.
Psychological function and exercise have shown an emphatic relationship. Exercise not only makes you feel good in the short run, but also has been shown to positively affect anxiety and depression.
