The influence of muscle strength and aerobic fitness on functional recovery in professional soccer players

摘要

BACKGROUND: Well-developed physical qualities may protect athletes from exercise-induced muscle damage and accelerate recovery follow-ing exercise. This study examined the influence of muscle strength and aerobic fitness on recovery from competitive soccer matches.METHODS: Fourteen players from the English Premier League 2 (age 18 +/- 1 years; height 1.78 +/- 0.54 m; mass 73.8 +/- 6.3 kg) were equally divided (median split) into a higher or lower group for muscle strength and aerobic fitness, according to their isometric mid-thigh pull (IMPT) and maxi-mal aerobic speed test (MAST) scores, respectively. The following markers of recovery were assessed before (48-h prematch), 12 h (M+1), 36 h (M+2) and 60 h (M+3) after-3 matches: countermovement jump height (CMJ), reactive strength index (RSI), muscle soreness (DOMS) and wellbeing.RESULTS: IMTP was positively correlated with the recovery of CMJ, RSI and DOMS following matches (P2.10), CMJ was >4% greater at M+1 to M+3 (all P2.21) and RSI was >3% higher at M+2 and M+3 (all P1.25). Players in the H-MAST group did not recover quicker for any variable (all P>0.05).CONCLUSIONS: This study showed that stronger players recovered quicker after matches and highlights the importance of lower-body strength training for soccer players.
