Physical fitness refers to a set of attributes that people have or achieve that relate to the ability to perform physical activity (Caspersen, Powell, & Christenson, 1985). These attributes include components of fitness that may or may not relate to health-related physical fitness. Health-related fitness relates to those components of fitness that are affected by habitual physical activity and relate to health status. As mentioned above, they include aerobic functioning, body composition, and musculoskeletal functioning. The BPFT includes test items that measure the extent to which these attributes are achieved. Physical activity consists of bodily movement produced by skeletal muscle. The primary role of physical activity is the conditioning benefit it provides in developing health-related physical fitness. Types of activities include exercise, sport, training, dance, and play.
