The purpose of this study was to examine the acute skeletal muscle and perceptual responses to blood flow restriction (BFR) exercise to failure between narrow nylon and elastic inflatable cuffs at rest and during exercise. Torque and muscle thickness was measured pre, post, and 5, 20, 40, and 60 min post-exercise with muscle activation being measured throughout exercise. Resting arterial occlusion pressure was different between the nylon [139 (14) mmHg] and elastic [246 (71) mmHg, p < 0.001] cuffs. However, when exercising at 40 % of each cuff's respective arterial occlusion pressure [nylon: 57 (7) vs. elastic: 106 (38) mmHg, p < 0.001], there were no differences in repetitions to failure, torque, muscle thickness, or muscle activation between the cuffs. Exercising with cuffs of different material but similar width resulted in the same acute muscular response when the cuffs were inflated to a pressure relative to each individual cuff.
本研究的目的是在静息和运动期间，检查窄尼龙袖带和弹性充气袖带在血流限制（BFR）运动至疲劳时对急性骨骼肌和感知的反应。在运动前、运动后以及运动后5、20、40和60分钟测量扭矩和肌肉厚度，并在整个运动过程中测量肌肉激活情况。尼龙袖带[139（14）mmHg]和弹性袖带[246（71）mmHg，p<0.001]的静息动脉闭塞压力不同。然而，当以每个袖带各自动脉闭塞压力的40%进行运动时[尼龙袖带：57（7）mmHg对弹性袖带：106（38）mmHg，p<0.001]，袖带之间在运动至疲劳的重复次数、扭矩、肌肉厚度或肌肉激活方面没有差异。当将不同材料但宽度相似的袖带充气至相对于每个袖带的压力时，会产生相同的急性肌肉反应。
