EFFECT OF ADDITIONAL CONCURRENT STRENGTH AND REPEATED SPRINT TRAINING ON PHYSICAL PERFORMANCE IN COLLEGIATE BASKETBALL PLAYERS

Abstract

This study aims to investigate the effects of additional concurrent strength and repeated sprint training on the physical performance of collegiate basketball players. A matched-group design was conducted with 24 male collegiate basketball players (19.75 ± 0.18 years, 181.92 ± 5.11 cm, 79.83 ± 1.30 kg). Participants were assigned to a 6-week training group matched for their 1 repetition maximum (1RM) score: (1) a concurrent strength and repeated sprint training group (CTG, n = 12), or (2) a control group (NTG, n = 12) which underwent their normal basketball training. In the CTG, participants performed the concurrent strength and repeated sprint training twice a week, consisting of 3 sets of 8 repetitions of barbell squats, deadlifts, and power cleans at 80% 1RM. The repeated sprint training program consisted of 3 sets of 6 repetitions of 30-m shuttle run (turn at 15-m) performed at maximum speed, with a 20-second rest between repetitions, and a 5-minute rest between sets. Both groups performed a muscle strength test, countermovement jumps (CMJ), repeated sprint ability (RSA) test (RSAbest, RSA worst, RSAtotal time, RSAmean, RSAdecrement), Agility T-Test, 20 m sprint test, and Yo-Yo intermittent recovery test level 1 (Yo-Yo IR1). Both groups showed improvements in muscle strength, agility and CMJ height after training (P < 0.001), but there were no significant differences between groups (P>0.05). The CTG demonstrated significant improvement in RSAmean, RSAbest, 20 m sprint time, Yo-Yo IR1 and VO2 max compared to the NTG group (P
