This study examined the effects of different types of neuromuscular electrical stimulation (NMES) programs on vertical jump performance. Twenty seven healthy trained male students in sports-sciences were recruited and randomized into three groups. The control group (C group, n = 8) did not perform NMES training. Two other groups underwent 3 training sessions a week over 5 weeks on the quadriceps femoris muscle [F group (n = 9): stimulation with an 80 Hz current for 15 min for improving muscle strength; E group (n = 10): stimulation with a 25 Hz current for 60 min for improving muscle endurance]. The height of the vertical jump was measured before NMES training (test 1), one week (test 2) and five weeks (test 3) after the end of the programs. The results showed that the height of the vertical jump significantly increased in both the F and E groups between tests 1 and 2 (5 cm and 3 cm respectively). Results of test 3 showed that both groups preserved their gains. A NMES training program destined to improve muscle endurance does not interfere on vertical jump performance. It can even durably enhance it in the same way as a NMES training program destined to improve muscle strength. Thus, to improve muscle endurance without deteriorating muscle power, sportsmen can use electrical stimulation.
本研究考察了不同类型的神经肌肉电刺激（NMES）方案对垂直跳跃成绩的影响。招募了27名运动科学专业健康且受过训练的男性学生，并将他们随机分为三组。对照组（C组，n = 8）不进行NMES训练。另外两组在股四头肌上进行为期5周、每周3次的训练[F组（n = 9）：用80Hz电流刺激15分钟以增强肌肉力量；E组（n = 10）：用25Hz电流刺激60分钟以提高肌肉耐力]。在NMES训练前（测试1）、训练结束后1周（测试2）和5周（测试3）测量垂直跳跃高度。结果显示，F组和E组在测试1和测试2之间垂直跳跃高度均显著增加（分别增加5厘米和3厘米）。测试3结果表明两组均保持了所取得的进步。旨在提高肌肉耐力的NMES训练方案不会干扰垂直跳跃成绩。它甚至可以像旨在增强肌肉力量的NMES训练方案一样持久地提高垂直跳跃成绩。因此，为了在不降低肌肉力量的情况下提高肌肉耐力，运动员可以使用电刺激。
