Strength training elicits benefits both in performance and on a psychological level in women, such as increased muscle strength and improved self-esteem. Whole-body electromyostimulation (WB-EMS) could be a training strategy for enhancing muscular strength. The aim of this study was to assess the acute effects of a single session of WB-EMS superimposed over classic resistance training on isometric strength, endurance strength and flexibility. Furthermore, the safety of the protocol was assessed by monitoring the levels of creatine kinase (CK) 48 h after the training protocol was completed. Sixteen active women (aged 22.06 ± 1.88) were randomly assigned to an experimental group (EG) ( = 8) and a control group (CG) ( = 8). The EG performed four sets of 12 repetitions of three strength exercises with superimposed WB-EMS, while the CG performed the same protocol without WB-EMS. RM-ANOVA showed a significant timegroup interaction on posterior kinetic chain extensors' mean and peak strength in the EG (F = 10.036; = 0.007; and F = 20.719; < 0.001; respectively). A significant timegroup interaction was found in the sit and reach test for the EG (F = 10.362; = 0.006). Finally, ANOVA performed on the CK levels showed no significant difference between the groups (F = 0.715; = 0.412). WB-EMS training led to an immediate improvement in strength performance and flexibility, and this protocol was shown to be safe in terms of CK levels, 48 h after completing the training protocol.
力量训练对女性的身体机能和心理层面都有益处，比如增强肌肉力量和提升自尊。全身肌电刺激（WB-EMS）可能是一种增强肌肉力量的训练策略。本研究旨在评估单次WB-EMS叠加于传统阻力训练对静力性力量、耐力力量和柔韧性的急性影响。此外，通过在训练方案完成后48小时监测肌酸激酶（CK）水平来评估该方案的安全性。16名活跃女性（年龄22.06±1.88岁）被随机分为实验组（EG）（n = 8）和对照组（CG）（n = 8）。实验组进行三组力量练习，每组12次重复，并叠加WB-EMS，而对照组进行相同方案但不使用WB-EMS。重复测量方差分析显示，实验组后动力链伸肌的平均力量和峰值力量存在显著的时间组交互作用（F = 10.036；p = 0.007；F = 20.719；p < 0.001）。在实验组的坐位体前屈测试中发现了显著的时间组交互作用（F = 10.362；p = 0.006）。最后，对CK水平进行的方差分析显示两组之间无显著差异（F = 0.715；p = 0.412）。WB-EMS训练导致力量表现和柔韧性立即得到改善，并且在完成训练方案48小时后，就CK水平而言，该方案被证明是安全的。
