Abstract

BACKGROUND

Neuromuscular electrical stimulation (NMES) devices for abdominal muscles are being marketed to the general public to improve physical appearance. Abdominal muscles play an important role in lumbopelvic stability for optimizing performance. We investigated the effects of NMES training of abdominal muscles on muscle size, muscle strength, endurance, and lumbopelvic stability.

METHODS

Twenty-three subjects (12 females, 11 males) performed abdominal muscle NMES training for 8 weeks. Before and after NMES training, we measured muscle size (cross-sectional area [CSA] of the rectus abdominals [RA] and lateral abdominal wall [LAW]) by magnetic resonance imaging, muscle strength (trunk flexor and side bridge strength), endurance (trunk flexor and side bridge endurance time), and lumbopelvic stability (one-leg loading test).

RESULTS

There were significant increases between pre- and post-NMES training differences in the size (CSA of RA 21.7-25.4%, P<0.001; CSA of LAW 9.00-9.71%, P<0.001), strength (trunk flexor 14.9%, P<0.05; side bridge 33.7-53.6%, P<0.05), and endurance (trunk flexor 29.1%, P<0.05; side bridge 24.6-28.9%, P<0.05) of abdominal muscles and lumbopelvic stability (37.2-37.4%, P<0.05).

CONCLUSIONS

NMES training could be applied to increase muscle size and muscle performances of abdominal muscles in sports and fitness fields.

摘要

背景

用于腹部肌肉的神经肌肉电刺激（NMES）设备正面向大众市场销售，以改善身体外观。腹部肌肉在优化腰骨盆稳定性以提高运动表现方面发挥着重要作用。我们研究了腹部肌肉的NMES训练对肌肉大小、肌肉力量、耐力和腰骨盆稳定性的影响。

方法

23名受试者（12名女性，11名男性）进行了为期8周的腹部肌肉NMES训练。在NMES训练前后，我们通过磁共振成像测量肌肉大小（腹直肌[RA]和腹外侧壁[LAW]的横截面积[CSA]）、肌肉力量（躯干屈肌和侧桥力量）、耐力（躯干屈肌和侧桥耐力时间）以及腰骨盆稳定性（单腿负重试验）。

结果

NMES训练前后，腹部肌肉的大小（RA的CSA增加21.7 - 25.4%，P < 0.001；LAW的CSA增加9.00 - 9.71%，P < 0.001）、力量（躯干屈肌增加14.9%，P < 0.05；侧桥增加33.7 - 53.6%，P < 0.05）、耐力（躯干屈肌增加29.1%，P < 0.05；侧桥增加24.6 - 28.9%，P < 0.05）以及腰骨盆稳定性（增加37.2 - 37.4%，P < 0.05）均有显著提高。
