- Abstract
High‐intensity activities during a soccer game, such as sprints, accelerations, change of direction, jumps, shoot, requires high force through the Stretch – Shortening Cycle (SSC), which is associated with the exercise – induced muscle damage. Consequences of muscle damage are muscle soreness and loss of muscle power. The aim of this study was to investigate the effect of two consecutive soccer games on indices of exercise – induced muscle damage (EIMD) and physical performance (PP). In this study participated 10 soccer players (age: 20.7years, height: 177cm, weight: 73kg, body fat: 6.4%, VO2max 55 ml/kg/min) who joined the first week of experimental design without playing in matches. The second week included two soccer games which had 90 minutes duration and separated 72 hours. Measurements executed daily in the morning during first and second week up to 48 hours after the second soccer game. The EIMD determined through thigh circumferences, knee joint of range motion (KJRM) and delayed onset of muscle damage (DOMS). The PP determined through squat jump (SJ) and countermovement jump (CJ). Data was analyzed with ANOVA repeated measures. Results show that thigh circumferences were significantly different 48 hours after the first and second game, and DOMS was higher 24 and 48 hours after second game. PP deteriorated in both SJ and CJ which is ranged between 10‐20% with the greatest decrement 48 hours after the soccer games. In conclusion, the two soccer games caused noticeable changes in the EIMD and PP indices. Coaches should plan suitable training sessions after games taking account of enough recovery period for the players.
