Effect of CST versus RST on Physical Parameters in College Level Football Players

The primary purpose of the this study was to explore the effects of a solely repeat sprint training (RST) regime compared to combined training (COM) consisting of RST, aerobic interval- , continuous aerobic- & explosive leg power-training on various physical parameters of football conditioning. Forty-six male college level football players (22 ± 2 years; 66 ± 8 kg; 52 ± 6 ml/min/kg) participated in the study. Players were allocated to either a RST, COM or control (CON) group. Players trained for six-weeks during the pre-season phase. Outcome variables assessed included aerobic capacity, yo-yo intermittent recovery test 2 (YYIRT2), 30-meter sprint, agility and explosive power. Both the RST and COM training groups significantly improved distance ran on the YYIRT2 and the maximum velocity on the VO2 max test compared to CON after six weeks of training (p<0.01). Only the RST group improved VO2 max compared to CON (p
