OBJECTIVES: The main objective of this study was to compare two cold water immersion protocols, continuous or intermittent, on recovery in basketball players. METHODS: Ten male basketball players (age 14 +/- 0.4 years, body mass 65.4 +/- 9.1 kg, height 175 +/- 7.3 cm, body fat % 10.3 +/- 4) were included in the study. After three 90-minute training sessions (avg heart rate 158 +/- 11.92, 156 +/- 7.06 and 151 +/- 10.44 bpm), participants were grouped into a continuous immersion (12 min at 12 +/- 0.4 degrees C) group, intermittent immersion (4 x 2 min immersion at 12 +/- 0.4 degrees C plus 1 min out of water) group and a control group (CG). Countermovement jump (CMJ), muscle pain and thigh volume were measured. RESULTS: Both cold water immersion protocols were effective in reducing the pain 24 and 48 hours after training compared with the CG (F[3,54] = 2.91, p = 0.016, eta-p2 = 0.24). Concerning CMJ change, % differences occurred at 24 (z = 11.04, p = 0.004) and 48 hours (z = 14.01, p < 0.001) in comparison with the CG. Regarding the muscle volume, the statistical analysis did not report a significant interaction (F[3,54] = 2.42, p = 0.058). CONCLUSION: Both cold water immersion CWI protocols are effective in improving recovery in basketball players.
