This study examined the neural adaptations associated with a low-volume Wingate-based High Intensity Interval Training (HIIT).
Fourteen recreationally trained males were divided into an experimental (HIIT) and a control group to determine whether a short-term (4 weeks) Wingate-based HIIT program could alter the Hoffmann (H-) reflex, volitional (V-) wave and maximum voluntary contraction (MVC) of the plantar-flexor muscles, and the peak power achieved during a Wingate test.
Absolute and relative peak power increased in the HIIT group (ABS_P: +14.7%, P=0.001; and REL_P: +15.0%, P=0.001), but not in the control group (ABS_P: P=0.466; and REL_P: P=0.493). However, no significant changes were found in the MVC (P>0.05 for both groups). There was a significant increase in H-reflex size after HIIT (+24.5%, P=0.004), while it remained unchanged in the control group (P=0.134). No significant changes were observed either in the V-wave or in the V/M ratio (P>0.05 for both groups).
The Wingate-based training led to an increased peak power together with a higher spinal excitability. However, no changes were found either in the volitional wave or in the MVC, indicating a lack of adaptation in the central motor drive.
本研究探讨与小运动量基于温盖特测试的高强度间歇训练(HIIT)相关的神经适应性变化。
将14名有运动习惯的男性分为实验组(HIIT组)和对照组,以确定短期(4周)基于温盖特测试的HIIT方案是否会改变霍夫曼(H-)反射、随意(V-)波、跖屈肌最大自主收缩(MVC)以及温盖特测试中的峰值功率。
HIIT组的绝对和相对峰值功率均增加(绝对峰值功率:+14.7%,P = 0.001;相对峰值功率:+15.0%,P = 0.001),而对照组未增加(绝对峰值功率:P = 0.466;相对峰值功率:P = 0.493)。然而,两组的MVC均无显著变化(P>0.05)。HIIT后H反射大小显著增加(+24.5%,P = 0.004),而对照组保持不变(P = 0.134)。V波或V/M比值均无显著变化(两组P>0.05)。
基于温盖特测试的训练导致峰值功率增加以及脊髓兴奋性提高。然而,随意波和MVC均未发生变化,表明中枢运动驱动缺乏适应性改变。
