Recently, whole body-electromyostimulation (WB-EMS) has upgraded its functions and capabilities and has overcome limitations and inconveniences from past systems. Although the efficacy and safety of EMS have been examined in some studies, specific guidelines for applying WB-EMS are lacking. To determine the efficacy and safety of applying it in healthy men to improve cardiopulmonary and psychophysiological variables when applying WB-EMS. Sixty-four participants were randomly grouped into control group (without electrical stimuli) or WB-EMS group after a 6-week baseline period. The control group (n=33; female. 15; male, 18) wore the WB-EMS suit as much as the WB-EMS group (n=31; female, 15; male, 16). There were no abnormal changes in the cardiopulmonary variables (heart rate, systolic blood pressure [SBP], diastolic blood pressure, and oxygen uptake) during or after the graded exercise test (GXT) in both groups. There was a significant decrease in SBP and an increase of oxygen uptake from stages 3 to 5 of the GXT in the WB-EMS group. The psychophysiological factors for a WB-EMS group, which consisted of soreness, anxiety, fatigability, and sleeplessness were significantly decreased after the experiment. The application of WB-EMS in healthy young men did not negatively affect the cardiopulmonary and psychophysiological factors. Rather, the application of WB-EMS improved SBP and oxygen uptake in submaximal and maximal stages of GXT. This study also confirmed that 6 weeks of WB-EMS training can improve psychophysiological factors.
最近，全身肌电刺激（WB-EMS）已经升级了其功能和能力，克服了以往系统的局限性和不便之处。尽管在一些研究中已经对EMS的疗效和安全性进行了检验，但缺乏应用WB-EMS的具体指南。目的是确定在健康男性中应用WB-EMS以改善心肺和心理生理变量时的疗效和安全性。64名参与者在经过6周的基线期后被随机分为对照组（无电刺激）或WB-EMS组。对照组（n = 33；女性15名；男性18名）穿着WB-EMS套装的时间与WB-EMS组（n = 31；女性15名；男性16名）相同。两组在分级运动试验（GXT）期间或之后，心肺变量（心率、收缩压[SBP]、舒张压和摄氧量）均未出现异常变化。WB-EMS组在GXT的第3至5阶段SBP显著降低，摄氧量增加。由酸痛、焦虑、易疲劳和失眠组成的WB-EMS组的心理生理因素在实验后显著降低。在健康年轻男性中应用WB-EMS对心肺和心理生理因素没有负面影响。相反，WB-EMS的应用改善了GXT次最大和最大阶段的SBP和摄氧量。本研究还证实，6周的WB-EMS训练可以改善心理生理因素。
