Purpose: The purpose of this study was to examine the changes in reflex-electromechanical delay (EMD) as a result of 2- and 4-wks of variable resistance training (VRT) or dynamic constant external resistance (DCER) leg press training. Material and Methods: Thirty-six men were randomised into either the Control, DCER, or VRT groups. The DCER and VRT groups performed 3 sets of 10 leg press repetitions 3-d·wk-1 for 4-wks. Reflex-EMD was measured at Baseline, Week-2, and Week-4. Results: The reflex-EMD durations decreased from Baseline at Week-2 and Week-4 for the VRT group, but not the DCER or Control groups. The reflex response < electrochemical process < mechanical process < total reflex-EMD for all groups. Conclusions: VRT elicited greater reflex adaptations compared to DCER training which indicated that VRT may be beneficial to incorporate into training or physical therapy programmes for pilots, soldiers, elderly, athletes, or professions that require quick reflexes and response times.

四周的腿部推举训练后，在反射途径上进行可变阻力训练与传统的重量训练。

目的：本研究的目的是研究由于2周和4周可变电阻训练（VRT）或动态恒定外电阻（DCER）腿部推举训练引起的反射机电延迟（EMD）的变化。材料和方法：36名男性被随机分为对照组，DCER或VRT组。DCER和VRT组进行了3组每10腿一次的压腿重复训练，每次3-d·wk-1重复4-wks。在基线，第2周和第4周测量Reflex-EMD。结果：VRT组的反射EMD持续时间从第2周和第4周的基线开始降低，但DCER或对照组没有降低。所有组的反射反应<电化学过程<机械过程<总反射EMD。结论：
