In the BPFT, health-related fitness refers to those components of fitness affected by habitual physical activity and related to health status. It is defined as a state characterized by (a) an ability to perform and sustain daily activities and (b) demonstration of traits or capacities associated with a low risk of premature development of diseases and conditions related to movement. Health-related components of fitness adopted for this test include aerobic functioning, body composition, and musculoskeletal functioning. In the BPFT, test items are selected to measure these components of fitness and standards related to health are developed for each of the tests items to evaluate fitness. The premise in regard to assessment is that if children and youth reach the standards associated with the test items representing these components of physical fitness, they will have attained levels of physical fitness that are appropriate for health and which will enable them to enter adulthood with the protection that physical fitness affords as a buffer to the natural degeneration that comes with middle age and beyond.
