This study aimed to investigate the impact of 12 weeks of high-intensity interval training (HIIT) on hemodynamic variables at rest and during exercise in patients with obstructive sleep apnoea. Twenty-six obese adults with moderate-to-severe OSA (AHI = 42 ± 22.9 e/h) were randomly assigned to HIIT or a control group. Sleep parameters, ambulatorial, aortic, and during-exercise SBP and DBP were assessed at baseline and after 12 weeks. Generalized estimated equations assessed differences between groups over time. When compared with control group, HIIT reduced AHI (17.1 ± 6.2; e/h, P < 0.01), SBPnighttime (10.2 ± 5.0 mmHg; P = 0.034), DBPnighttime (7.9 ± 4.0 mmHg; P = 0.038), DBPaortic (5.5 ± 2.9 mmHg; P = 0.048), and SBPmax (29.6 ± 11.8 mmHg; P = 0.045). In patients with OSA, 12 weeks of HIIT decreases sleep apnoea severity and blood pressure in rest and during exercise.

12 周高强度间歇训练对阻塞性睡眠呼吸暂停患者休息和运动时血流动力学变量的影响。

本研究旨在调查 12 周高强度间歇训练 (HIIT) 对阻塞性睡眠呼吸暂停患者休息时和运动时血流动力学变量的影响。26 名患有中度至重度 OSA（AHI = 42 ± 22.9 e/h）的肥胖成人被随机分配到 HIIT 组或对照组。在基线和 12 周后评估睡眠参数、动态、主动脉和运动期间的 SBP 和 DBP。广义估计方程评估了组间随时间变化的差异。与对照组相比，HIIT 降低了 AHI（17.1 ± 6.2；e/h，P < 0.01）、夜间收缩压（10.2 ± 5.0 mmHg；P = 0.034）、夜间舒张压（7.9 ± 4.0 mmHg；P = 0.038）、主动脉舒张压（5.5） ± 2.9 mmHg；P = 0.048）和 SBPmax（29.6 ± 11.8 mmHg；P = 0.045）。对于 OSA 患者，12 周的 HIIT 可以降低睡眠呼吸暂停的严重程度以及休息和运动时的血压。
