Document Summary

Physical fitness: (cid:271)od(cid:455)"s a(cid:271)ilit(cid:455) to respo(cid:374)d or adapt to the de(cid:373)a(cid:374)ds a(cid:374)d stress of ph(cid:455)si(cid:272)al effort. Health-related fitness: physical capabilities that contribute to health (5 components) Ability of body to perform prolonged, large-muscle, dynamic exercise at moderate to high levels of intensity. Endurance training: exercise intended specifically to improve cardiorespiratory endurance; usually involves prolonged, large-muscle, dynamic exercises. Amount of force a muscle can produce with a single maximum effort. Older people lose muscle cells, some become non-functional (lose attachment to nervous) Strength training benefits this and reduces risk of osteoporosis. Ability of a muscle or group of muscles to remain contracted or to contract repeatedly for a long time. Developed by stressing muscles with greater load than used to (type and amt of stress applied) Ability to move joints through full range of motion stiffness=unnatural body postures stressing joints and muscles (get healthy range of motion) Proportion of fat and fat-free mass (muscle, bone, water) in body.
