摘要

背景:肌肉疲劳在阻力练习中不可避免,因此对其进行监测对于保持运动成绩和降低受伤风险至关重要。据报道,感知用力评分(RPE)和速度损失是抗阻力爆发练习中肌肉疲劳的可靠指标。然而,这些指标的有效性只得到了间接评估。本研究旨在直接检验 RPE 和速度损失作为爆发性深蹲 (BS) 运动中肌肉疲劳指标的有效性。方法:17 名训练有素的男子以一次重复最大动作的 65% 完成了不同运动量(低、中、高)的三种 BS 任务。在整个任务过程中测量 RPE、频谱疲劳指数 (SFI) 和速度损失。结果显示在不同条件下,总体 RPE(p < 0.001)和速度损失(p < 0.001)均有显著影响,而 SFI 则无显著影响。随着任务的进行,RPE 和 SFI 明显增加(p < 0.001),而速度没有明显下降。在 RPE 和 SFI 之间(r = 0.325,p < 0.001)以及速度损失和 SFI 之间(r = 0.224,p < 0.001)发现了明显但微弱的相关性。结论这些研究结果表明,RPE 和肌肉疲劳水平会相应增加,表明 RPE 可作为爆发性 BS 运动的实用、间接疲劳标记。然而,速度损失可能无法完全反映下半身爆发力训练中的肌肉疲劳,因此不应作为唯一指标。此外,在将速度相关参数作为阻力训练的间接生理指标时应谨慎。RPE、速度损失和 SFI 之间存在明显但微弱的相关性,这表明评估下半身运动中的肌肉疲劳仍具有挑战性。

Can Perceived Exertion and Velocity Loss Serve as Indirect Indicators of Muscle Fatigue During Explosive Back Squat Exercise?

Background: Muscle fatigue is inevitable during resistance exercises, making its monitoring essential for maintaining athletic performance and reducing the risk of injury. Ratings of perceived exertion (RPE) and velocity loss have been reported as reliable indicators of muscle fatigue during explosive resistance exercises. However, their validity has been assessed only indirectly. This study aimed to directly examine the validity of RPE and velocity loss as markers of muscle fatigue during explosive back squat (BS) exercises. Methods: Seventeen trained men performed three BS tasks with varying volumes (low, medium, high) at 65% of their one-repetition maximum. RPE, spectral fatigue index (SFI), and velocity loss were measured throughout the tasks. Results: Significant effects were observed across conditions for overall RPE (p < 0.001) and velocity loss (p < 0.001), while no significant effect was found for SFI. RPE and SFI increased significantly as the tasks progressed (p < 0.001), while velocity did not significantly decrease. Significant but weak correlations were found between RPE and SFI (r = 0.325, p < 0.001) and between velocity loss and SFI (r = 0.224, p < 0.001). Conclusions: These findings suggest that RPE and muscle fatigue levels increase correspondingly, indicating that RPE could serve as a practical, indirect fatigue marker for explosive BS exercises. However, velocity loss may not fully reflect muscle fatigue during lower-body explosive training and should not be used as the sole indicator. Additionally, caution is warranted when applying velocity-related parameters as indirect physiological markers for resistance exercises. The significant but weak correlations between RPE, velocity loss, and SFI suggest that assessing muscle fatigue in lower-body exercises remains challenging.
