近红外光谱学 (NIRS) 在运动诱导的肌肉损伤 (EIMD) 后显示肌肉氧化的微妙变化. 休息组织和指数 (TSI) 和冲刺氧化动力学可能有助于非侵入性地监测肌肉恢复.
科学领域:
- 运动医学 运动医学
- 运动生理学 运动生理学
- 生物医学工程 生物医学工程
背景情况:
- 运动诱导的肌肉损伤 (EIMD) 损害了肌肉功能和恢复.
- 近红外光谱 (NIRS) 是一种评估肌肉氧化的非侵入性工具.
- 在实际条件下,NIRS对EIMD的敏感性需要进一步调查.
研究的目的:
- 为了研究EIMD之后的静止组织和指数 (TSI) 和冲刺阶段氧化动力学的变化.
- 确定NIRS在特征肌肉状态后EIMD的潜力.
主要方法:
- 17名娱乐活跃的男性进行了10×10次古怪的坐 (80%是1RM),以诱导EIMD.
- 测量包括休息的TSI,冲刺氧化动力学,反运动跳跃 (CMJ),健康和肌酸酶 (CK).
- 数据是在基线和运动后1,24,48,72,96小时收集的.
主要成果:
- 对于CK,性能或NIRS变量,随着时间的推移或在组之间没有观察到统计学上显著的差异.
- 效果大小分析揭示了CMJ,健康,CK和NIRS指标的小到极大的影响.
- 冲刺1期间的脱度幅度和速率在EIMD后1小时显示出很大的影响;休息的TSI在24小时稍微增加.
结论:
- 休息的 TSI 和冲刺阶段的 NIRS 索引显示了与 EIMD 相关的小而系统的变化.
- 在运动引起的肌肉损伤后,NIRS具有非侵入性肌肉状态特征的潜力.
