Introduction:
According to WHO physical activity is defined as moment produced by skeletal muscle that requires energy expenditure. It regulates moderate intensity, physical activity such as walking , cycling or participating in sports has significant benefits for health. It reduces the risk of CVD’s, diabetes, colon and breast cancer.
According to Krause “physical activity involves bodily movement produced by the contraction of skeletal muscle that requires energy expenditure in excess of resting energy expenditure”.
Movement produced by skleletal muscle requires energy expenditure, physical activity that is planned, structured and repetitive and has a final or intermediate objective for …show more content…
The initiation and maintenance of regular physical activity in adults depend on biological and sociocultural variables that demand across a life span. (Seefeldt,Malina, Clark 2002)
Benefits of physical activity:
Regular aerobic physical activity plays a role in primary and secondary prevention of cardiovascular diseases.
Cardiovascular functional capacity is increased by exercise training and decreases myocardial oxygen demand at any level of physical activity in apparently healthy persons as well as in most people with cardiovascular disease.
Physical activity helps to control:
Obesity
Blood lipid abnormalities
Diabetes
An independent blood-pressure lowering effect is added by aerobic physical activity in certain hypertensive groups with a decrease of 8-10 mm Hg in both systolic and diastolic pressure measurements.
Physical inactivity is an independent risk factor for developing coronary artery disease.

According to research that had a purpose that physical activity greatly reduces the risk of chronic diseases (CVD’s, Diabetes, Cancer, Obesity and Osteoporosis). Results were shared after the completion of report. The magnitude of the risk reduction reported were: 75% for breast cancer, 49% for cardiovascular and heart diseases, 35% for diabetes, 22% for colorectal cancer. Increased physical activity also prevented the weight gain associated with aging at least 2-times greater in individuals who were more active compared with those who were inactive. Limited new findings have been reported for the beneficial role of physical activity in fall-related injuries, depression and emotional distress.
