BACKGROUND: To examine the relationship between repeated sprint ability (RSA, 6 x 40 m (20 m + 20 m) with 20-s recovery) and neuromuscular and aerobic fitness variables in male collegiate soccer players.
METHODS: Twenty-six players (age 22.5 ± 3.6 yr) were tested on separate days for countermovement jump (CMJ), squat jump (SJ), and standing long jump (LJ), and for maximal oxygen consumption ( O2max), velocity at onset of blood lactate accumulation (vOBLA), maximal aerobic speed (v O2max), and peak blood lactate concentration (peak [La]). They were also tested for best and mean times on a repeated shuttle sprint ability test.
RESULTS: RSA best time (r = -0.73 and r = -0.54) and RSA mean sprint time (r = - 0.69 and r = -0.62) were significantly (p < 0.01) correlated with LJ and CMJ, respectively. Significant correlations (p < 0.05) were also found between RSA mean sprint time and sprint decrement with vOBLA (r = -0.44) and peak [La] (r = 0.47), respectively.
CONCLUSION: This study showed that RSA performance had a large to very large association with the individual level of jump performance and to a smaller extent to aerobic fitness variables in male collegiate soccer players. Given this finding, lower limbs’ explosive-strength performance should be regarded as a relevant factor for male soccer.
