在这项荟萃分析中，力竭阻力训练与非力竭阻力训练在力量和肥大方面没有显着差异。根据身体部位、运动选择或研究设计对研究进行分层的亚组分析中，训练条件之间没有显着差异。当考虑到各组之间训练量不相等的研究时，分析表明非失败训练对力量增益有显着的支持。此外，在针对接受过阻力训练的个体的亚组分析中，分析显示训练对力竭对肌肉肥大有显着影响。我们的目的是对肌肉衰竭或非衰竭训练对肌肉力量和肥大的影响进行系统回顾和荟萃分析。效应量 (ES) 的荟萃分析探讨了力竭训练与非力竭训练对力量和肥大的影响。亚组荟萃分析探讨了各种变量的潜在调节作用，例如训练状态（训练与未训练）、训练量（相等训练量与非相等训练量）、身体区域（上部与下部）、运动选择（多关节运动与单关节运动（仅针对力量））和研究设计（独立组与非独立组）。该评价纳入了十五项研究。所有研究都包括年轻人作为参与者。荟萃分析表明，肌肉力量训练条件（ES=–0.09，95%置信区间（95%CI）：–0.22至0.05）和肌肥大训练条件（ES=0.22，95%CI：–0.11至0.55）之间没有显着差异。根据身体部位、运动选择或研究设计对研究进行分层的亚组分析显示，训练条件之间没有显着差异。在各组之间训练量不相等的研究中，分析显示，无失败训练对力量增益有显着优势（ES=–0.32，95%CI：–0.57 至 –0.07）。在针对阻力训练个体的亚组分析中，分析显示训练至力竭对肌肉肥大有显着影响（ES=0.15，95%CI：0.03-0.26）。肌肉力竭训练似乎并不需要增加力量和肌肉大小。然而，以这种方式进行的训练似乎也不会对这些适应产生不利影响。应该在老年人和训练有素的个人中进行更多的研究，以提高这些研究结果的普遍性。
In this meta-analysis, there was no significant difference between resistance training to failure vs. non-failure on strength and hypertrophy. There was no significant difference between training conditions in subgroup analyses that stratified the studies according to body-region, exercise selection, or study design. When considering studies that did not equate training volume between the groups, the analysis showed significant favoring of non-failure training on strength gains. Additionally, in the subgroup analysis for resistance-trained individuals, the analysis showed a significant effect of training to failure for muscle hypertrophy. We aimed to perform a systematic review and meta-analysis of the effects of training to muscle failure or non-failure on muscular strength and hypertrophy. Meta-analyses of effect sizes (ESs) explored the effects of training to failure vs. non-failure on strength and hypertrophy. Subgroup meta-analyses explored potential moderating effects of variables such as training status (trained vs. untrained), training volume (volume equated vs. volume non-equated), body region (upper vs. lower), exercise selection (multi- vs. single-joint exercises (only for strength)), and study design (independent vs. dependent groups). Fifteen studies were included in the review. All studies included young adults as participants. Meta-analysis indicated no significant difference between the training conditions for muscular strength (ES = –0.09, 95% confidence interval (95%CI): –0.22 to 0.05) and for hypertrophy (ES = 0.22, 95%CI: –0.11 to 0.55). Subgroup analyses that stratified the studies according to body region, exercise selection, or study design showed no significant differences between training conditions. In studies that did not equate training volume between the groups, the analysis showed significant favoring of non-failure training on strength gains (ES = –0.32, 95%CI: –0.57 to –0.07). In the subgroup analysis for resistance-trained individuals, the analysis showed a significant effect of training to failure for muscle hypertrophy (ES = 0.15, 95%CI: 0.03–0.26). Training to muscle failure does not seem to be required for gains in strength and muscle size. However, training in this manner does not seem to have detrimental effects on these adaptations, either. More studies should be conducted among older adults and highly trained individuals to improve the generalizability of these findings.
