The purpose of this study was to assess athletic performance measures following two different loading conditions in the back squat exercise. Fourteen NCAA Division I tennis players were randomly assigned to either a low-resistance (50-60% of 1 repetition maximum [1RM]) training group or a high-resistance (65-90% 1RM) training group. The eight weeks of training consisted of 3 training sessions per week using a complete strength training program designed for sport performance enhancement. Performance in the 1RM back squat, 10 yard sprint and a countermovement vertical jump (CMJ) was assessed. There were no significant pretest to posttest differences in improving lower-body power production as measured by the 1 RM back squat, 10yd sprint and countermovement vertical jump in either group. The results of this study indicate that low-resistance, high-velocity training and high-resistance, low-velocity training is equally effective for improving lower-body power production. === School of Physical Education, Sport, and Exercise Science
