Regularly engaging in aerobic exercise is associated with improved asthma control and quality of life in adults with mild to moderate severity asthma. Previous intervention research has primarily employed moderate intensity continuous aerobic exercise protocols. As such, the impact of high intensity interval training (HIIT) on asthma control is poorly understood.
A six-week, low volume HIIT intervention (3 times/week, 20 min bouts) was conducted in adults with asthma ( = 20). Asthma control was assessed using the Asthma Control Questionnaire-7 (ACQ-7).
ACQ-7 improved from pre to post-intervention (pre: 0.8 ± 0.6; post: 0.5 ± 0.4, = 0.02, Cohens = 0.5). In total, 7/20 (35%) participants experienced clinically meaningful improvements in ACQ-7.
A low-volume HIIT intervention led to statistically and clinically significant improvements in asthma control as well as improved exertional dyspnea and exercise enjoyment.
定期进行有氧运动与改善轻至中度严重哮喘成人的哮喘控制和生活质量有关。以前的干预研究主要采用中等强度持续有氧运动方案。因此，高强度间歇训练（HIIT）对哮喘控制的影响知之甚少。
对 20 名哮喘患者进行为期六周、低容量 HIIT 干预（每周 3 次，每次 20 分钟）。使用哮喘控制问卷-7（ACQ-7）评估哮喘控制。
ACQ-7 在干预前后有所改善（干预前：0.8 ± 0.6；干预后：0.5 ± 0.4， = 0.02，Cohens = 0.5）。共有 7/20（35%）的参与者在 ACQ-7 上有临床意义的改善。
低容量 HIIT 干预可显著改善哮喘控制，并可改善运动性呼吸困难和运动享受。
