Abstract

The purpose of this study was to compare two lower body, unilateral and bilateral, training styles on the development of athletic performance variables. Twenty-one division two collegiate swimmers (age 20.38 ± S.D.1.3), who were split into two groups, completed the training program. An eight week training program that utilized a modified single leg squat (MSLS) and unilateral plyometrics (n=11) or a bilateral back squat (BBS) and bilateral plyometrics (n=10) was used to train the athletes. The volume of training was equal across groups. Pre-post test assessments included a 5RM squat test, bilateral and unilateral jump height, a T-test, and goniometry, as differences were assessed. Significance was found after comparing the 5RM squat posttest (p=.043) and hip extension as measured by goniometry (p=.036) with the BBS group performing better when evaluated relative to the MSLS group. No significant differences were found in any of the other variables.
