概括
在高强度间歇运动 (HIIE) 后,在10°C下10分钟的冷水浸泡 (CWI) 并没有改善神经肌肉恢复或第二天的表现. 这项研究发现,CWI对运动员来说没有比室温休息的优势.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 恢复战略 恢复策略
背景情况:
- 冷水浸泡 (CWI) 是运动后恢复的流行方法.
- 它对神经肌肉功能恢复的影响尚未完全理解.
- 高强度间歇运动 (HIIE) 显著影响神经肌肉功能.
研究的目的:
- 调查CWI对HIIE后神经肌肉恢复的影响.
- 为了比较CWI与室温休息 (RT) 恢复.
- 在HIIE和恢复干预后评估第二天的运动表现.
主要方法:
- 随机交叉研究与12名参与者.
- 涉及脚足底 flexor 和 dorsiflexor 收缩的HIIE 协议.
- 干预:10分钟的CWI (10°C) 或RT.
- 在24小时内测量的神经肌肉功能和肌内温度.
主要成果:
- 在这两种条件下,最大自发收缩扭矩在运动后3小时内都保持不变.
- 电气刺激的10 Hz扭矩恢复在CWI和RT之间是相似的.
- 使用RT比CWI更快地恢复50Hz的扭矩,但10:50Hz的比率显示CWI立即恢复.
- 无论采用何种恢复方法,第二天的HIIE表现都是可比的.
结论:
- 在10°C的10分钟CWI不会增强HIIE后的神经肌肉恢复.
- 与RT相比,CWI并没有改善随后的运动表现.
- 目前的证据表明,CWI对于这种类型的运动可能不优于被动恢复.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
