Power has long been considered to be a skill-related fitness component. However, based on recent evidence, a strong case can be made for the classification of power as a health-related fitness component. Additionally, the evidence indicates that performing physical activities that build power is associated with the healthy development of bones (e.g., enhanced bone mass and architecture, reduced fracture risk) and muscles. Tests of power are good proxy measures for bone health, and the evidence provides support for including measures of power in health-related fitness test batteries for youth. The current research literature also supports the inclusion of physical activities that build power in school physical education and athletic programs, community programs, and programs for adults, including older adults.
