What is the Meaning of Physical Activity?

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.

What is the Origin of Physical Activity?

The term is a descriptive, common-sense phrase that has been scientifically formalized in public health and exercise physiology since the mid-20th century. Physical derives from the Greek physis (nature), and activity from the Latin activitas (action), denoting the active use of the body.

What is the Mechanism of Physical Activity?

Muscle contraction during physical activity increases glucose uptake independently of insulin, improving insulin sensitivity over time. Acute exercise stimulates the release of key hormones, including growth hormone and testosterone, which promote tissue repair and anabolism. Furthermore, the mechanical stress on bone stimulates osteoblast activity, while the overall energy expenditure aids in maintaining a healthy body composition and reducing visceral adiposity.
