To investigate the changes in serum growth hormone (GH), testosterone, and insulin-like growth factor 1 (IGF-1) during low-intensity resistance exercise under different cuff pressures.
We performed a single-blind, cross-over design study. Twenty-five healthy young men performed three exercise protocols as follows: 1) no blood flow restriction exercise (control group), 2) resistance exercise at 40% of arterial occlusion pressure (AOP) (low group), and 3) resistance exercise at 70% of AOP (high group). Blood lactate, GH, testosterone, and IGF-1 levels were measured at four time points.
There were no differences in the indices before exercise. The blood flow restriction exercise under different pressures had different effects on each index and there was an interactive effect. GH levels were significantly higher in the high group than in the other groups after exercise. Immediately after exercise, IGF-1 and testosterone levels were significantly higher in the high group than in the other groups. At 15 minutes after exercise, testosterone levels were significantly higher in the high group than in the other groups.
Low-intensity resistance exercise combined with blood flow restriction effectively increases GH, IGF-1, and testosterone levels in young men. Increasing the cuff pressure results in greater levels of hormone secretion.
探讨不同袖带压力下低强度抗阻运动时血清生长激素（GH）、睾酮和胰岛素样生长因子 1（IGF-1）的变化。
我们进行了一项单盲、交叉设计研究。25 名健康年轻男性分别进行以下 3 种运动方案：1）无血流限制运动（对照组）；2）动脉闭塞压的 40%（低组）；3）动脉闭塞压的 70%（高组）的抗阻运动。在 4 个时间点测量血乳酸、GH、睾酮和 IGF-1 水平。
运动前各指标无差异。不同压力下的血流限制运动对各项指标的影响不同，存在交互作用。运动后，高组的 GH 水平明显高于其他组。运动后即刻，高组的 IGF-1 和睾酮水平明显高于其他组。运动后 15 分钟，高组的睾酮水平明显高于其他组。
低强度抗阻运动联合血流限制可有效提高青年男性的 GH、IGF-1 和睾酮水平。增加袖带压力可导致激素分泌水平增加。
