Abstract

This project was conducted in order to determine if strengthening the knee extensors of one leg using dynamic contractions would result in an increase in the knee extensors of the opposite (contralateral) leg.

The experiment consisted of a. pretest to determine the maximum amount of weight that could be lifted by each leg for all subjects. The preferred leg of each subject was then subjected to a five-week progressive resistance exercise program conducted on a daily basis. A post-test was then given in a similar manner to the pretest.

The participants were fourteen University of North Dakota Junior Physical Therapy students.

A "t" test was applied to the data to determine if a. significant difference existed between means of the pretest and post-test for the nonexercised leg. This "t" test yielded significance at the .01 level. The nonexercised limb showed a mean increase of 4.64 pounds while the exercised limb showed a. mean increase of 14.28 pounds.
