Physical Activity

Meaning

Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure, ranging from structured exercise to daily tasks like walking or gardening. Regular engagement in physical activity is a powerful modulator of the endocrine system, positively influencing insulin sensitivity, bone density, and the production of anabolic hormones. It is a cornerstone of preventative medicine and a key intervention in managing metabolic and hormonal health.
