Abstract：
To date, most studies examined the effects of cold water immersion (CWI) on neuromuscular control following exercise solely on measuring proprioception, no study explores changes in the brain and muscles. The aim of this study was to investigate the effects of CWI following exercise on knee neuromuscular control capacity, and physiological and perceptual responses. In a crossover control design, fifteen participants performed an exhaustion exercise. Subsequently, they underwent a 10 min recovery intervention, either in the form of passively seated rest (CON) or CWI at 15 °C. The knee proprioception, oxygenated cerebral hemoglobin concentrations (Δ[HbO]), and muscle activation during the proprioception test, physiological and perceptual responses were measured. CWI did not have a significant effect on proprioception at the post-intervention but attenuated the reductions in Δ[HbO] in the primary sensory cortex and posterior parietal cortex (p < 0.05). The root mean square of vastus medialis was higher in the CWI compared to the CON. CWI effectively reduced core temperature and mean skin temperature and improved the rating of perceived exertion and thermal sensation. These results indicated that 10 min of CWI at 15 °C post-exercise had no negative effect on the neuromuscular control of the knee joint but could improve subjective perception and decrease body temperature.
摘要：
迄今为止,大多数研究检查了冷水浸泡（CWI）对运动后神经肌肉控制的影响，仅在测量本体感受时，没有研究探索大脑和肌肉的变化。这项研究的目的是研究运动后CWI对膝关节神经肌肉控制能力的影响，以及生理和知觉反应。在交叉控制设计中，15名参与者进行了精疲力竭运动。随后，他们接受了10分钟的康复干预，在15°C下以被动坐式休息(CON)或CWI的形式。膝盖本体感觉,氧合大脑血红蛋白浓度（Δ[HbO]），和本体感觉测试中的肌肉激活，测量生理和知觉反应。CWI在干预后对本体感觉没有显着影响，但减弱了初级感觉皮层和后顶叶皮层中Δ[HbO]的降低（p<0.05）。与CON相比，CWI中股内侧肌的均方根较高。CWI有效地降低了核心温度和平均皮肤温度，并提高了感知的劳累和热感觉的等级。这些结果表明，运动后15°C的CWI10分钟对膝关节的神经肌肉控制没有负面影响，但可以改善主观感知并降低体温。
