简介
Background
The effects of high-intensity interval training (HIIT) on dyspnea and aerobic fitness in adults with asthma are poorly understood.
Objective
To compare constant-load exercise (CLE) versus HIIT for improvements in dyspnea symptoms and clinical control in adults with moderate-to-severe asthma.
Methods
Participants were randomized into 2 groups: CLE (n = 27; started with 70% of maximal watts [Wmax] obtained during cardiopulmonary exercise testing [CPET]) and HIIT (n = 28; started with 80% and increased until 140% Wmax). Exercise training lasted 12 weeks (twice/week, 40 minutes/session on a cycle ergometer), and the intensity was based on CPET. Clinical asthma control (Asthma Control Questionnaire), aerobic fitness (the peak of oxygen uptake), health-related quality of life (Asthma Quality of Life Questionnaire), physical activity levels (PAL; accelerometer), symptoms of anxiety and depression …
