The purpose of this study was to evaluate the ability of electrical stimulation (2,500-Hz sine waves, interrupted for 50 pulsed bursts per second) to improve muscle torque using low-dosage training characteristics. Fifteen healthy subjects (9 men, 6 women), 20 to 32 years of age, participated in the experiment. All subjects received electrical stimulation of the right anterior thigh musculature while their left leg served as the control. Electrical stimulation was repeated eight times per session, each stimulation producing isometric torque equal to 50% of the subject's maximum voluntary isometric contraction. The sessions were repeated twice a week over a period of five weeks. Results showed that electrical stimulation, when used with the specified low-dosage training characteristics of this study, will augment quadriceps femoris muscle torque of men.
本研究的目的是利用低剂量训练特性评估电刺激（2500赫兹正弦波，每秒中断50个脉冲群）改善肌肉扭矩的能力。15名年龄在20至32岁之间的健康受试者（9名男性，6名女性）参与了该实验。所有受试者右大腿前侧肌肉接受电刺激，而左腿作为对照。每次训练电刺激重复8次，每次刺激产生的等长扭矩等于受试者最大自主等长收缩的50%。训练每周重复两次，持续五周。结果表明，当按照本研究规定的低剂量训练特性使用电刺激时，可增强男性股四头肌的扭矩。
