The aim of this study was to verify and compare the effects of electromyostimulation training (EMS), strength training (ST), and both combined (STEMS), through the analysis of the elbow flexors muscle thickness. Forty subjects (24.45 ± 3.53 years), were randomly divided equally in 4 groups: 3 experimental groups and 1 control group. Each experimental group was submitted to one of three interventions, either an ST protocol, an EMS protocol, or a STEMS protocol. The control group (CG) did not perform any type of physical activity. Ultrasonography (US) was used to measure muscle thickness (MT) at 50 and 60% of the distance between the acromion and the olecranon. The results showed a significant difference in the elbow flexors muscle thickness after 8 weeks, both in the STG, EMSG, and STEMSG, but not in the CG. However, no significant differences were observed between the intervention protocols. It seems that an increase in MT can be obtained using either with ST, EMS, or both combined, however, the results doesn't support the overlap of one method in relation to the others. EMS can be another interesting tool to induce muscle hypertrophy, but not necessarily better.
本研究旨在通过分析肘屈肌肌肉厚度来验证和比较肌电刺激训练（EMS）、力量训练（ST）和两者联合（STEMS）的效果。共有 40 名受试者（24.45±3.53 岁），随机平均分为 4 组：3 个实验组和 1 个对照组。每个实验组接受以下三种干预措施之一：ST 方案、EMS 方案或 STEMS 方案。对照组（CG）不进行任何形式的体育活动。超声（US）用于测量肩峰和鹰嘴之间距离的 50%和 60%处的肌肉厚度（MT）。结果显示，8 周后，STG、EMSG 和 STEMSG 组的肘屈肌肌肉厚度均有显著差异，但 CG 组无显著差异。然而，各干预方案之间未观察到显著差异。似乎可以通过 ST、EMS 或两者联合使用来增加 MT，但结果不支持一种方法相对于其他方法的重叠。EMS 可以是另一种诱导肌肉肥大的有趣工具，但不一定更好。
