Abstract
Obese adults with asthma have an increased number of comorbidities and reduced daily life physical activity (DLPA), which may worsen asthma symptoms. Exercise is recommended to improve asthma outcomes; however, the benefits of exercise for psychosocial comorbidities and DLPA have been poorly investigated.
Aim: To assess the effects of exercise on DLPA, asthma symptoms and psychosocial comorbidities in obese adults with asthma.
Methods: 55 obese asthmatics were randomly assigned to either a weight-loss program+exercise (WL+E group) or a weight-loss program+sham (WL+S group) (2xW for 3 months). DLPA (GT3X accelerometer), asthma symptoms (daily diary), sleep quality (Actisleep/ Berlin questionnaire) and anxiety and depression symptoms (HADs) were quantified before and after treatment.
Results: After 3 months, the WL+E group presented a significant increase in DLPA (3,068±2,325 vs. 729±1,118 steps/day), in the moderate and vigorous PA (18.2±17.9 vs 7.9±13.8 minutes/day) and in light-intensity PA compared with the WL+S group; however, neither group showed significant changes in sedentary time. Significant improvements in the number of asthma-symptom-free days (14.5±9.6 vs. 8.6±11.4 d/mo), sleep efficiency (6.6±5.1 vs. 1.3±4.7%) and latency (-3.7±5.9 vs. 0.2±5.6 min) were also observed in the WL+E group. The proportion of patients with improvements in depression symptoms (76.4 vs. 16.6%) and a lower risk of developing obstructive sleep apnea (56.5 vs. 16.3%) was greater in the WL+E group than in the WL+S group (P<0.05).
Conclusions: Our results strongly suggest that exercise training in a weight loss program improves DLPA, sleep efficiency and depression and asthma symptoms in obese adults with asthma.
