The primary aim of this investigation was to determine the ergogenic effect of neuromuscular electrical stimulation (NMES) amongst twenty apparently healthy males during submaximal exercise. In Session 1, 20 participants (Age = 35.0 ± 15.0 yrs; Height = 179.9 ± 8.5 cm; Body Mass = 85.4 ± 12.0 kg) were familiarized with all equipment. Sessions 2-4 included the following randomized 5-min trials a) Rest and Rest+NMES, b) Rest, Arms-Only, Arms+NMES, and c) Rest, Arms+Legs, Arms+Legs+NMES. Physiological variables collected during rest and submaximal exercise were volume of oxygen (VO), heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), respiratory exchange ratio (RER), and rate pressure product (RPP). Paired sample t-test was used to determine significant mean differences between the NMES and non-NMES trials. Bonferroni post-hoc analysis established alpha at 0.008. From the 18 paired -tests, the only observed significant mean difference (t(19) = -6.4, < 0.001) was RER values between the Arms-Only trial compared to the Arms+NMES trial (0.94 and 1.00, respectively). While RER displayed a significant difference, from a practical perspective, however, these differences were deemed non-physiologically significant. Viewed in concert, findings from this study suggests that NMES utilization does not evoke an acute ergogenic effect amongst an apparently healthy male population.
本研究的主要目的是确定在次最大运动期间，神经肌肉电刺激（NMES）对20名表面健康男性的促力效应。在第1阶段，20名参与者（年龄 = 35.0 ± 15.0岁；身高 = 179.9 ± 8.5厘米；体重 = 85.4 ± 12.0千克）熟悉了所有设备。第2 - 4阶段包括以下随机的5分钟试验：a）休息和休息 + NMES，b）休息、仅上肢、上肢 + NMES，以及c）休息、上肢 + 下肢、上肢 + 下肢 + NMES。在休息和次最大运动期间收集的生理变量包括氧含量（VO）、心率（HR）、收缩压和舒张压（SBP和DBP）、呼吸交换率（RER）以及率压积（RPP）。采用配对样本t检验来确定NMES试验和非NMES试验之间的显著平均差异。Bonferroni事后分析将α设定为0.008。在18次配对检验中，唯一观察到的显著平均差异（t(19) = -6.4，< 0.001）是仅上肢试验与上肢 + NMES试验之间的RER值（分别为0.94和1.00）。虽然RER显示出显著差异，但从实际角度来看，这些差异被认为在生理上不显著。综合来看，本研究结果表明，在表面健康的男性群体中，使用NMES不会引发急性促力效应。
