The purpose of the study was to explore the effects of selected combinations of rate of movement, resistance, and two variations of the deep knee squat on collateral ligament stretch in the knee joint, quadriceps muscle strength measured at two leg extension angles, and knee joint flexibility. Sixty-nine male, volunteer, Caucasian students provided the data, and the total experiment was 10 weeks in duration — one week each for pre- and post-testing and 8 weeks for experimental exercises. The main hypotheses were tested in null form and involved the nesting of selected treatment cells into planned contrasts. Multivariate analysis of covariance failed to reject the null hypotheses at the .05 level. Selected variations of the deep squat and half-squat exercises did not produce significant differences in their effect on collateral ligament stretch, quadriceps muscle strength, or knee joint flexibility.
