摘要

背景:骨骼肌约占我们身体质量的40%,在活动、新陈代谢和产热中起着至关重要的作用。这项研究深入研究了全身肌肉电刺激(WB-EMS)训练对超重个体肌肉生长和合成代谢因子的影响。30名参与者被随机分配到EMS组和对照组。方法:EMS组坚持一个训练方案,包括一个全身EMS装置,设计成同时和独立刺激不同的身体区域。这种创新的装置管理双极电流,脉冲频率为85 Hz,脉冲宽度跨越350µs,矩形波形具有0.4秒的斜坡。刺激模式在6秒的激活和4秒的休息之间振荡。该设备精确定位了腿部、大腿前后、手臂、臀部、腹部、胸部和上下背部,覆盖面积达2600 cm2。培训计划包括为期8周的24次WB-EMS课程。每周训练3次,每次20分钟。会议之间安排了一个专门的休息日,以促进恢复和适应。结果:结果表明,运动训练显著降低身体质量指数(BMI) (pp结论:因此,EMS训练成为传统运动常规的一种高效、有效的替代方法,可以增强骨骼肌功能。

Training with electrical muscle stimulation: a novel method to improve Body Mass Index, lipid profile, growth hormone, and cortisol in overweight subjects.

Background: Skeletal muscles constitute approximately 40% of our body mass, performing crucial roles in mobility, metabolism, and heat generation. This study delves into the impact of whole body-electrical muscle stimulation (WB-EMS) training on muscle growth and anabolic factors in individuals grappling with excess weight. A cohort of 30 participants was randomly assigned to an EMS group and a control group.

Methods: The EMS group adhered to a training regimen involving a whole-body EMS device engineered to concurrently and independently stimulate various body regions. This innovative apparatus administered a bipolar electric current with a pulse frequency of 85 Hz, a pulse width spanning 350 µs, and a rectangular waveform featuring a 0.4-second ramp. Stimulation patterns oscillated between 6 seconds of activation and 4 seconds of rest. The device precisely targeted the legs, anterior and posterior thighs, arms, buttocks, abdomen, chest, and lower and upper back while covering a substantial area of 2600 cm2. The training program included 24 WB-EMS sessions conducted over 8 weeks. There were 3 training sessions per week, each lasting 20 minutes. A dedicated rest day was scheduled between sessions to facilitate recovery and adaptation.

Results: The results showed that exercise training significantly reduced Body Mass Index (BMI) (P<0.0001) and significantly improved cholesterol levels (P<0.0016), including reductions in low-density lipoprotein (LDL) (P<0.0146) and very low-density lipoprotein (VLDL) (P<0.0003). Along with an increase in high-density lipoprotein (HDL) (P<0.0238). In addition, the study showed an increase in growth hormone levels (P<0.0001) along with a decrease in cortisol levels (P<0.0008) and transforming growth factor-β (TGF-β) (P<0.0187).

Conclusions: Consequently, EMS training emerges as a time-efficient and effective alternative to conventional exercise routines, enhancing skeletal muscle function.
