Acute peripheral fatigue may occur due to muscle damage during volleyball, resulting in a temporary decrease in
jump performance. This study aimed to investigate the effect of cold water immersion (CWI) of the lower limbs between volleyball games on jump performance. Twelve university volleyball players participated in this randomized crossover study. The participants played two games, each of three sets, in a gymnasium. There was a 30-minute rest in between the games. During rest time, the participants were assigned to the CON group (30 minutes of seated rest) or the COOL group (15 minutes of CWI (15°) up to the level of the iliac crest and 15 minutes of seated rest). The counter-movement jump (CMJ) after the second game and 24 hours later, and the spike decision rate in the second game were significantly higher in the COOL group (p<0.05). The perceived recovery status before the second game and the session rating of perceived exertion (s-RPE) after the second game were also significantly improved in the COOL group (p<0.05). CWI of the lower extremities between volleyball games suppressed the decline of the CMJ height at the end of exercise and the spike decision rate. The decrease in tissue temperature caused by CWI of the lower extremities may have improved s-RPE and the perceived recovery status, which in turn, affected the jump performance.
