Document Summary

A form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. Muscle changes length during the contraction, and contractions produce movements of a constant speed. To measure this contraction a isokinetic dynamometer is required. Concentric contraction: the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. Eccentric: the muscle lengthens due to the resistance being greater than the force the muscle is producing. Involves muscle shortening as it goes through a range of motion; usually termed flexion. Involves muscle lengthening during movement; usually termed extension. Training status: joint angle, muscle cross-sectional area, speed of movement, muscle fiber type, age, gender. The ability to perform maximal voluntary muscular contraction in order to overcome powerful external resistances. The ability to overcome external resistance by developing high rate of muscular contraction; also known as speed strength. The ability to resist fatigue in strength performance of longer duration.
