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°C) group, intermittent immersion (4 x 2 min immersion at 12 ± 0.4 °C + 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, η = .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.
目的
本研究的主要目的是比较两种冷水浸泡方案（持续或间歇）对篮球运动员恢复情况的影响。
方法
本研究纳入了10名男性篮球运动员（年龄：14±0.4岁，体重：65.4±9.1千克，身高：175±7.3厘米，体脂率：10.3±4）。在进行了三次90分钟的训练课程（平均心率分别为158±11.92、156±7.06和151±10.44次/分钟）后，参与者被分为持续浸泡组（在12±0.4°C下浸泡12分钟）、间歇浸泡组（在12±0.4°C下浸泡4次，每次2分钟，中间出水1分钟）和对照组（CG）。测量了纵跳高度（CMJ）、肌肉疼痛和大腿体积。
结果
与对照组相比，两种冷水浸泡方案在训练后24小时和48小时均能有效减轻疼痛（F(3.54)=2.91，p=0.016，η=0.24）。关于CMJ变化，与对照组相比，在24小时（Z=11.04，p=0.004）和48小时（Z=14.01，p<0.001）出现了百分比差异。关于肌肉体积，统计分析未报告显著的交互作用（F(3.54)=2.42，p=0.058）。
结论
两种冷水浸泡方案均能有效改善篮球运动员的恢复情况。
