We studied the effects of self-administered neuromuscular electrical stimulation (NMES) on changes in strength, endurance, selected anthropometric measures, and subject's perceived shape and satisfaction of the abdominal wall. Twenty-four adults (experimental group) stimulated their abdominals 5 days per week (20-40 minutes per session) for 8 weeks and refrained from engaging in any additional exercise during the study. A control group (N=16) refrained from exercising the abdominals or engaging in any other exercise training during the study. Subjects were tested at the beginning, mid-point, and end of the study. Isometric strength of the abdominal muscles was tested using a isokinetic dynamometer, endurance was measured using the ACSM curl-up test, abdominal circumference was measured using a steel tape measure, and body shape and satisfaction were assessed via questionnaire. The stimulation group had a 58% increase in abdominal strength, whereas the control group did not change. The stimulation group also had a 100% increase in abdominal endurance versus a 28% increase in the control group. Waist circumference decreased by of 3.5 cm in the stimulation group compared to no significant change in the control group. All 24 subjects in the stimulation group felt that their midsections were more "toned" and "firmed" and 13/24 (54%) felt that their posture had improved as a result of the stimulation. None of the control group subjects reported changes in these parameters. There were no significant differences in body weight, BMI, or skinfold thickness over the course of the study in either group. NMES, as used in the current study, resulted in significant improvements in the muscular strength and endurance of the abdominal region, as well as subject's perceived shape and satisfaction of the mid-section. Key PointsElectrical muscle stimulation (EMS) was effective in increasing muscle strength and enduranceAll subjects perceived their abdominal muscles to be firmer and more toned as a result of EMSAbdominal and waist girth was also significantly reduced, despite no changes in body weight or subcutaneous fat.
我们研究了自我管理的神经肌肉电刺激（NMES）对力量、耐力、人体测量指标以及腹部形态和满意度的影响。24 名成年人（实验组）每周进行 5 天的腹部刺激（每次 20-40 分钟），并在研究期间避免进行任何其他运动。对照组（N=16）在研究期间避免锻炼腹部或进行任何其他运动训练。受试者在研究开始、中点和结束时进行测试。使用等速测力仪测试腹部肌肉等长力量，使用 ACSM 仰卧起坐测试测量耐力，使用钢卷尺测量腰围，通过问卷评估身体形态和满意度。刺激组的腹部力量增加了 58%，而对照组没有变化。刺激组的腹部耐力也增加了 100%，而对照组增加了 28%。刺激组的腰围减少了 3.5 厘米，而对照组没有明显变化。刺激组的 24 名受试者都觉得他们的腹部更“紧实”、“结实”，13/24（54%）的人觉得他们的姿势因刺激而有所改善。对照组的受试者均未报告这些参数发生变化。在研究过程中，两组的体重、BMI 或皮褶厚度均无显著差异。在当前研究中，使用 NMES 可显著提高腹部区域的肌肉力量和耐力，以及受试者对腹部形态和满意度的感知。关键点电刺激（EMS）有效增加肌肉力量和耐力所有受试者都认为他们的腹部肌肉因 EMS 而更加紧实和有弹性腹部和腰围也明显减少，尽管体重或皮下脂肪没有变化。
