In support of this, all players in the cold-water immersion group reported that they believed that the treatment was beneficial for recovery and would improve their subsequent performance, whereas only one player in the thermoneutral immersion group believed it would assist recovery. Halson et al. (2008) also reported that, compared with a passive restcondition, cold-water immersion enhanced the perception of recovery after a simulated 20-min cycling time-trial. Although these results suggest that cold-water immersion enhances the perception of recovery after exercise, the potential mechanism responsible for this effect remains to be identified.
