Fitness Components

Physical fitness is made up of three major components:
(1) health-related,
(2) skill-related, and
(3) physiological fitness.

Health-related physical fitness (HRPF) consists of those specific components that have a relationship with good health, or a lower risk of illness, particularly hypokinetic diseases and conditions.

Skill-related physical fitness (SRPF) consists of components that have a relationship with learning motor skills quickly and the ability to achieve a high level of performance in sports. I know of others who were able to improve their motor skills with practice so they are able shoot a basketball or kick a football well. Since they are fit (or possess SRF), they aremore likely to engage in regular physical activities; and because of this, they too will have enhanced HRF.

Physiological fitness relates to biological systems that are influenced by one‟s level of habitual physical activity (Bouchard et al., 1990). Unlike HRF and SRF which can be measured through performance tests using hand-held or portable devices (like the sit-and-reach box and the weighing scale) that can be conducted in the field or classrooms, physiological fitness is different because its components can be measured using more expensive equipment and in a laboratory or medically-supervised facility. Its components include metabolic fitness (MetF), morphological fitness (MorF) and bone integrity (BI).
