Physical activity is defined as any bodily movement produced by skeletal muscles that requires an expenditure of energy. Physical inactivity causes an estimated 6 percent of deaths globally, or 3.2 million deaths every year, making it the fourth-leading risk for global mortality, reports the World Health Organization.
Regular physical activity in adults reduces the risk of hypertension, coronary heart disease, stroke, diabetes, breast cancer, colon cancer and depression, WHO states. It also improves health.
On the other hand, not getting at least 150 minutes of physical activity a week is estimated to cause 21 to 25 percent of breast and colon cancer, 27 percent of diabetes, and 30 percent of ischaemic heart disease deaths, according to Medical News Today.
Physical activity includes all movement that takes energy. This includes activities such as chores or walking while at work. Exercise, a type of physical activity, is planned, structured and repetitive and serves the purpose of improving one or more components of physical fitness.
