We investigated the acute myogenic response to resistance exercise with and without blood-flow restriction (BFR). Six men and women (age, 22 ± 1 years) performed unilateral knee extensions at 40% of 1-repetition maximum with or without (CNTRL) BFR applied via pressure cuff inflated to 220 mm Hg. Muscle biopsies were collected at 4 h and 24 h postexercise. Addition of BFR increased myoD and c-Met messenger RNA expression relative to CNTRL. Expression of hepatocyte growth factor protein was significantly higher following CNTRL.
我们研究了有无血流限制(BFR)情况下抗阻运动的急性肌源性反应。六名男性和女性(年龄22±1岁)在1次重复最大值的40%下进行单侧膝关节伸展,施加或不施加(对照组)通过充气至220毫米汞柱的压力袖带进行的BFR。在运动后4小时和24小时采集肌肉活检样本。与对照组相比,添加BFR增加了肌分化抗原(myoD)和肝细胞生长因子受体(c-Met)信使核糖核酸(mRNA)的表达。对照组后肝细胞生长因子蛋白的表达显著更高。
