This study compares the acute and chronic response of high-load resistance training (HL) to low-load resistance training with low blood flow restriction (LL-BFR) pressure.
Participants completed elbow flexion with either HL or LL-BFR or nonexercise. In the chronic study, participants in the HL and LL-BFR groups were trained for 8 weeks to determine differences in muscle size and strength. The acute study examined the changes in pretesting/posttesting (Pre/Post) torque, muscle swelling, and blood lactate.
In the chronic study, similar changes in muscle size and strength were observed for both HL and LL-BFR. In the acute study, Pre/Post changes in the torque, muscle swelling, and blood lactate were similar between HL and LL-BFR.
Our findings indicate that pressure as low as 50% arterial occlusion can produce similar changes in muscle mass and strength compared with traditional HL. Muscle Nerve 56: E126-E133, 2017.
本研究比较了高负荷抗阻训练（HL）与低负荷抗阻训练加低血流限制（LL-BFR）压力的急性和慢性反应。
参与者分别进行HL、LL-BFR训练或不进行训练的屈肘动作。在慢性研究中，HL组和LL-BFR组的参与者接受为期8周的训练，以确定肌肉大小和力量的差异。急性研究则检测了测试前/测试后（Pre/Post）扭矩、肌肉肿胀和血乳酸的变化。
在慢性研究中，HL组和LL-BFR组的肌肉大小和力量变化相似。在急性研究中，HL组和LL-BFR组在扭矩、肌肉肿胀和血乳酸的Pre/Post变化相似。
我们的研究结果表明，与传统的HL相比，低至50%动脉闭塞压力可使肌肉质量和力量产生相似的变化。《肌肉与神经》56：E126-E133，2017年。
