The neuromuscular adaptations between ergometer-based high-intensity interval training (HIIT-T; n = 15), whole-body high-intensity interval training (HIIT-WB; n = 12) and moderate-intensity continuous training (MICT; n = 14) were compared in forty-one healthy men randomized to 16 weeks of training (3x per week). Two-way repeated measures analysis of variance (ANOVA) showed countermovement (CMJ) and squat (SJ) jump height (HIIT-T: 8.5 ± 13.3%; 3.1 ± 9.7%, HIIT-WB: 6.4 ± 9.8%, 10.4 ± 16.1% and MICT: 2.2 ± 9.5%; 4.4 ± 12.1%, respectively), SJ peak power (HIIT-T: 1.7 ± 3.9%; HIIT-WB : 6.4 ± 7.9%; MICT: 0.5 ± 6.5%) and CMJ rate of force development (HIIT-T: 58.1 ± 50.5%; HIIT-WB: 36.9 ± 54.2%; MICT: 38.4 ± 64.3%) improved similarly in all training groups (all p < 0.05). CMJ peak power increased only after HIIT-T (4.3 ± 5.5%) and HIIT-WB (4.5 ± 5.2%), while no differences were observed in both the rectus femoris and vastus lateralis maximal electromyographic amplitude. Finally, marked improvements were also observed in the number of repetitions in the HIIT-WB protocol at the eighth week, with no further improvement at the sixteenth week. These data suggest that 16 weeks of HIIT-WB is capable to improve neuromuscular function to a similar extent as HIIT-T and MICT.
41 名健康男性被随机分为三组，分别接受基于测力计的高强度间歇训练（HIIT-T；n=15）、全身高强度间歇训练（HIIT-WB；n=12）和中等强度持续训练（MICT；n=14），并进行 16 周的训练（每周 3 次）。双向重复测量方差分析（ANOVA）显示，反跳（CMJ）和深蹲（SJ）跳高技术（HIIT-T：8.5±13.3%；3.1±9.7%，HIIT-WB：6.4±9.8%，10.4±16.1%和 MICT：2.2±9.5%；4.4±12.1%）、SJ 峰值功率（HIIT-T：1.7±3.9%；HIIT-WB：6.4±7.9%；MICT：0.5±6.5%）和 CMJ 力量发展速率（HIIT-T：58.1±50.5%；HIIT-WB：36.9±54.2%；MICT：38.4±64.3%）在所有训练组中均有类似改善（均 P<0.05）。只有在 HIIT-T（4.3±5.5%）和 HIIT-WB（4.5±5.2%）后，CMJ 峰值功率才增加，而股直肌和股外侧肌最大肌电图振幅没有差异。最后，在第八周时，HIIT-WB 方案的重复次数也有明显改善，而在第十六周时则没有进一步改善。这些数据表明，16 周的 HIIT-WB 能够在类似程度上提高神经肌肉功能，与 HIIT-T 和 MICT 相似。
