Hermes, MJ and Fry, AC. Intentionally slow concentric velocity resistance exercise and strength adaptations: a meta-analysis. J Strength Cond Res 37(8): e470-e484, 2023-Intentionally slow-velocity resistance exercise (ISVRE) is suggested by some to be equally or more effective than fast or traditional velocities for increasing muscular strength. The purpose of this meta-analysis was to assess the effect ISVRE has on strength adaptations compared with faster or traditional velocities, with subgroup analyses exploring age, sex, and training status as confounding factors on the influence of velocity on strength adaptation. Eligible studies (n = 24) were required to be chronic (multiple weeks) randomized or nonrandomized comparative studies using dynamic constant external resistance for training and testing, and pre-post strength assessments. All studies examined healthy individuals (n = 625; fast or traditional n = 306, intentionally slow n = 319). A random-effects meta-analysis indicated a significant (p ≤ 0.05) effect in favor of fast training (effect size [ES] = 0.21, 95% confidence interval [CI] = 0.02-0.41, p = 0.03). Publication bias was noted through trim and fill analysis, with an adjusted effect size estimate of 0.32 (p < 0.001). Subgroup analyses indicated no difference between trained and untrained subjects (QM = 0.01, p = 0.93), and no difference between older and younger subgroups (QM = 0.09, p = 0.77), despite younger favoring faster (ES = 0.23, p = 0.049) and older not favoring either velocity (ES = 0.16, p = 0.46). Subgroup analysis also indicated women favored faster training (ES = 0.95, p < 0.001) in comparison to men (ES = 0.08, p = 0.58). Contrary to some previous reviews, these results indicate that chronic fast or traditional velocity resistance exercise increases muscular strength to a greater degree than ISVRE training. Resistance training velocity must be considered if strength is a desired outcome.
赫尔墨斯、MJ 和弗莱，AC。有意慢向心速度阻力训练与力量适应性：荟萃分析。J 力量与调节研究 37(8):e470-e484,2023-一些人认为，有意慢速度阻力训练（ISVRE）与快速度或传统速度一样有效或更有效，可增加肌肉力量。本荟萃分析的目的是评估与快速度或传统速度相比，ISVRE 对力量适应性的影响，并进行亚组分析，以探索年龄、性别和训练状态作为速度对力量适应性影响的混杂因素。符合条件的研究（n=24）必须是慢性（多周）随机或非随机比较研究，使用动态恒外阻力进行训练和测试，以及前后力量评估。所有研究均检查健康个体（n=625；快速度或传统速度 n=306，有意慢速度 n=319）。随机效应荟萃分析表明，快速度训练具有显著（p≤0.05）效果（效应大小[ES] = 0.21，95%置信区间[CI] = 0.02-0.41，p=0.03）。通过修剪和填充分析注意到存在发表偏倚，调整后的效应大小估计值为 0.32（p<0.001）。亚组分析表明，训练和未训练受试者之间无差异（QM=0.01，p=0.93），年龄较小和较大亚组之间无差异（QM=0.09，p=0.77），尽管年轻组更喜欢快速度（ES=0.23，p=0.049），而年龄较大组不倾向于任何速度（ES=0.16，p=0.46）。亚组分析还表明，与男性相比，女性更喜欢快速度训练（ES=0.95，p<0.001）（ES=0.08，p=0.58）。与之前的一些综述相反，这些结果表明，慢性快速度或传统速度阻力训练比 ISVRE 训练更能增加肌肉力量。如果力量是预期的结果，则必须考虑阻力训练速度。
