Document Summary

Muscular strength: greatest amount of force muscles can produce in a single maximal effort. Muscular endurance: ability to make repeated contractions against a defined resistance, or to sustain a defined muscular contraction. Physical fitness: ability to carry out daily tasks with vigor and alertness, without fatigue, and with ample energy to enjoy leisure time and meet unforeseen emergencies. Muscular power: ability to produce a maximal force in the shortest possible time. High power is a prime factor for athletic success. Power = work = f x d = m x a x d. Power (p) = work time: types of muscular contraction, dynamic (isotonic) contraction: bony levers move through a range of motion when muscles perform work; same force. Dynamic constant external resistance (dcer): external resistance does not change; (free weights) joint flexion and extension occur with each repetition. Constant length under load; same distance (velocity =
