Document Summary

Greatest amount of force that a body or its segments can produce in a single maximal effort. A combination of: combined contractile force of muscles causing movement, ability to coordinate agonists, antagonists, neutralizers, stabilizers, mechanical ratios of lever: Body wt. & strength (eg. football, shot put) Isotonics: dynamic constant, external resistance, dcer, constant resistance, varying tension: 120 30 , delorme. Berger: 3 sets, 6-8 reps, 2-3 days per week, min stimulus 60-65% rm. Resistance heavier than 1 rm (110-120% optimal) Combination of concentric eccentric cause greatest increases, especially legs. Muscular action performed at constant angular limb velocity. Ability to exert maximal force throughout the range of motion. Any force applied against the equipment results in equal reaction. 1953: hettinger and muller-germany: 2/3 max 6secs, once per day. Strength/power: small: 6 weeks-little, 1 year: 50% of gain lost. Muscle enurance: affected more 2 week sdh declines 60% Mvo2: 6% in 2-4 weeks, 15% decrease in 3 months.
