冷冻疗法是治疗软组织急性运动损伤的有效方法，但冷冻疗法对运动引起的肌肉损伤的效果尚不清楚。本研究的目的是评估冷水浸泡对剧烈离心运动后运动引起的肌肉损伤症状的影响。在等速测力计上进行一轮诱发损伤的肘屈肌离心运动（八组，每组五次最大往复收缩，0.58 rad.s(-1)）后，15 名年龄 22.0 +/- 2.0 岁（平均值 +/- s）的女性被分配到对照组（无治疗，n = 7）或冷冻治疗组（n = 8）。冷冻治疗组的受试者在离心运动后立即将其运动手臂浸入冷水（15 摄氏度）中 15 分钟，然后每 12 小时浸入一次，持续 15 分钟，总共 7 个疗程。在离心运动之前和之后 3 天测量肌肉压痛、血浆肌酸激酶活性、放松的肘部角度、等长力量和肿胀（上臂围）。方差分析显示，所有变量的时间主效应均显着（P < 0.05），其中肌肉压痛、肌酸激酶活性和上臂周长增加，等长肌力和放松肘角减小。 x时间组的放松肘角和肌酸激酶活性存在显着的交互作用（P < 0.05）。在离心运动后第 2 天和第 3 天，冷冻治疗组的放松肘部角度大于对照组，肌酸激酶活性较低。我们的结论是，虽然冷水浸泡可能会减少剧烈离心活动后的肌肉僵硬和运动后损伤的程度，但似乎对压痛和力量损失的感觉没有影响，而这是这种形式活动后的特征。
Cryotherapy is an effective treatment for acute sports injury to soft tissue, although the effect of cryotherapy on exercise-induced muscle damage is unclear. The aim of this study was to assess the effects of cold water immersion on the symptoms of exercise-induced muscle damage following strenuous eccentric exercise. After performing a bout of damage-inducing eccentric exercise (eight sets of five maximal reciprocal contractions at 0.58 rad.s(-1)) of the elbow flexors on an isokinetic dynamometer, 15 females aged 22.0 +/- 2.0 years (mean +/- s) were allocated to a control group (no treatment, n = 7) or a cryotherapy group (n = 8). Subjects in the cryotherapy group immersed their exercised arm in cold water (15 degrees C) for 15 min immediately after eccentric exercise and then every 12 h for 15 min for a total of seven sessions. Muscle tenderness, plasma creatine kinase activity, relaxed elbow angle, isometric strength and swelling (upper arm circumference) were measured immediately before and for 3 days after eccentric exercise. Analysis of variance revealed significant (P < 0.05) main effects for time for all variables, with increases in muscle tenderness, creatine kinase activity and upper arm circumference, and deceases in isometric strength and relaxed elbow angle. There were significant interactions (P < 0.05) of group x time for relaxed elbow angle and creatine kinase activity. Relaxed elbow angle was greater and creatine kinase activity lower for the cryotherapy group than the controls on days 2 and 3 following the eccentric exercise. We conclude that although cold water immersion may reduce muscle stiffness and the amount of post-exercise damage after strenuous eccentric activity, there appears to be no effect on the perception of tenderness and strength loss, which is characteristic after this form of activity.
