Blood flow restriction (BFR) training is a method partially restricting arterial inflow and fully restricting venous outflow in working musculature during exercise.1 The method uses a pneumatic tourniquet system and involves applying an external pressure, typically using a tourniquet cuff, to the most proximal region of the upper and/or lower limbs. When the cuff is inflated, there is gradual mechanical compression of the vasculature underneath the cuff, resulting in partial restriction of arterial blood flow to structures distal to the cuff, while more profoundly affecting venous outflow from under the cuff. The reduction in blood flow and subsequent localised hypoxia within exercising skeletal muscles during BFR training stimulates anaerobic metabolism and metabolite accumulation, upregulates muscle protein synthesis, induces systemic anabolic hormone release and possibly angiogenesis.2 BFR strength training has become an increasingly popular, accessible and useful adjunct method to increase skeletal muscle strength and induce hypertrophy …

血流限制力量训练在慢性阻塞性肺疾病中的作用

血流限制 (BFR) 训练是一种在运动过程中部分限制动脉流入并完全限制静脉流出工作肌肉组织的方法。1 该方法使用气动止血带系统，并涉及向最近端施加外部压力（通常使用止血带袖带）上肢和/或下肢区域。当袖带充气时，袖带下方的脉管系统逐渐受到机械压缩，导致流向袖带远端结构的动脉血流受到部分限制，同时更深刻地影响袖带下方的静脉流出。在 BFR 训练期间，运动骨骼肌内的血流量减少和随后的局部缺氧会刺激无氧代谢和代谢物积累，上调肌肉蛋白质合成，诱导全身合成代谢激素释放和可能的血管生成。2 BFR 力量训练已变得越来越流行、易于使用和有用。增加骨骼肌力量并诱导肥大的辅助方法......
