Abstract

Objective

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.

Methods

A six-week, low volume HIIT intervention (3 times/week, 20 min bouts) was conducted in adults with asthma (n = 20). Asthma control was assessed using the Asthma Control Questionnaire-7 (ACQ-7).

Results

ACQ-7 improved from pre to post-intervention (pre: 0.8 ± 0.6; post: 0.5 ± 0.4, p = 0.02, Cohens d = 0.5). In total, 7/20 (35%) participants experienced clinically meaningful improvements in ACQ-7.

Conclusion

A low-volume HIIT intervention led to statistically and clinically significant improvements in asthma control as well as improved exertional dyspnea and exercise enjoyment.

低容量高强度间歇训练可改善成人哮喘控制

摘要

客观的

定期进行有氧运动与改善轻度至中度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的连续有氧运动方案。因此，人们对高强度间歇训练 (HIIT) 对哮喘控制的影响知之甚少。

方法

对成人哮喘患者 ( n  = 20)进行了为期六周的低容量 HIIT 干预（3 次/周，20 分钟）。使用哮喘控制问卷 7 (ACQ-7) 评估哮喘控制。

结果

ACQ-7 从干预前到干预后都有所改善（前：0.8 ± 0.6；后：0.5 ± 0.4，p  = 0.02，Cohens d  = 0.5）。总共有 7/20 (35%) 的参与者在 ACQ-7 方面经历了具有临床意义的改善。

结论

低容量 HIIT 干预导致哮喘控制的统计学和临床​​显着改善，以及改善劳力性呼吸困难和运动乐趣。
