Abstract

The purpose of this investigation was to examine muscle excitation at maximal running capacity without blood flow restriction (BFR) relative to submaximal running bouts with BFR. Fourteen college-aged males randomly completed four, three-minute running bouts at 70, 80, and 90% of peak speed with BFR (70%BFR, 80%BFR, and 90%BFR) and without BFR at 100% of their peak speed (100%NOBFR). The surface electromyographic amplitudes of the vastus lateralis, rectus femoris, and vastus medialis muscles were assessed. Muscle excitation of the vastus lateralis was similar across most bouts; however, it was lower during the 70%BFR compared to 90%BFR (Meandiff =-4.67±- 0.22%; Bayesian 95% high-density interval [HDI]: - 7.07 to - 2.2) and 100%NOBFR (Meandiff =-2.94±- 0.27%; 95% HDI:-5.33 to-0.50) bouts. For the rectus femoris, muscle excitation largely increased across running speeds (70%BFR<80%BFR < 90%BFR; 90%BFR < 100%NOBFR). For the vastus medialis, muscle excitation was lower during the 70%BFR compared to 90%BFR (Meandiff =-8.15±- 0.28%; 95% HDI:-15.3 to-0.89). Submaximal running with BFR increased muscle excitation responses for the vastus lateralis and vastus medialis, such that muscle excitation was similar to 100%BFR, despite 10-20% reductions in running speed. The rectus femoris muscle, however, was not affected by BFR during the submaximal running bouts.

在血流受限的情况下跑步时肌肉特异性神经肌肉反应。
本研究的目的是检查无血流量限制(BFR)的最大跑步量与有BFR的次最大跑步量时的肌肉兴奋情况。14名大学年龄男性随机完成4组跑步,每组3分钟,分别以峰值速度的70,80和90% (70%BFR, 80%BFR和90%BFR)和不以峰值速度的100%(100%无BFR)跑步。评估股外侧肌、股直肌和股内侧肌的表面肌电图振幅。股外侧肌的兴奋在大多数回合中是相似的;然而,与90%BFR相比,70%BFR时它较低(Meandiff =-4.67±- 0.22%;贝叶斯95%高密度区间[HDI]: - 7.07 ~ - 2.2)和100%NOBFR (Meandiff =-2.94±- 0.27%;95% HDI:-5.33 -0.50)回合。对于股直肌,随着跑步速度的增加,肌肉兴奋程度大大增加(70%BFRBFR;90% bfr NOBFR)。对于股内侧肌,与90%BFR相比,70%BFR时肌肉兴奋度较低(Meandiff =-8.15±- 0.28%;95% HDI:-15.3 ~ 0.89)。伴随BFR的亚极限跑步增加了股外侧肌和股内侧肌的肌肉兴奋反应,尽管跑步速度降低了10-20%,但肌肉兴奋程度与100%BFR相似。然而,在次极限跑步时,BFR对股直肌没有影响。
