In the present study, the rating of perceived exertion after the 5-min shuttle run increased over time in both groups, suggesting that there was a residual fatigue effect as the 4-day tournament progressed. The increased rating of perceived exertion after this standardized shuttle run might could have been due to the increasing amount of exerciseinduced muscle damage over the tournament, as evidenced by the increased concentration of muscle damage markers (lactate dehydrogenase and creatine kinase) in both the cold-water immersion and thermoneutral immersion groups.
