Effects of Systematic, Heavy Resistive Exercise on Range of Joint Movement in Young Male Adults

A study was conducted on the effects of continual heavy, resistive exercise on the range of movement in certain selected joints of young male adults. An experimental group (n = 13) trained with weights for approximately six months during which time a control group (n = 13) participated in general physical education activities. Weight training did not have an appreciable effect upon range of joint movement throughout the body. A significant decrease did take place in the ability of the experimental group to move the extended arms, from a position at the side of the body, backward in the anteroposterior plane.
