- Dynamic hyperinflation and exercise limitations in obese asthmatic women(2017) FERREIRA, Palmira Gabriele; FREITAS, Patricia Duarte; SILVA, Aline Grandi; PORRAS, Desiderio Cano; STELMACH, Rafael; CUKIER, Alberto; FERNANDES, Frederico Leon Arrabal; MARTINS, Milton Arruda; CARVALHO, Celso R. F.Obese individuals and patients with asthma can develop dynamic hyperinflation (DH) during exercise; however, no previous study has investigated DH as a factor associated with reduced exercise capacity in obese asthmatic women. The aim of the present study was to examine the occurrence of DH and exercise limitations in obese asthmatics. Obese grade II [obese group (Ob-G); BMI 35-39.9 kg/m(2); n = 36] and nonobese [nonobese group (NOb-G); BMI 18.5-29.9 kg/m(2); n = 18] asthmatic patients performed a cardiopulmonary test to quantify peak (V) over dot(O2) and a sub-maximal exercise test to assess DH. Anthropometric measurements, quadriceps endurance, and lung function were also evaluated. A forward stepwise regression was used to evaluate the association between exercise tolerance (wattage) and limiting exercise factors. Fifty-four patients completed the protocol. The Ob-G (n = 36) presented higher peak (V) over dot(O2) values but lower power-to-weight ratio values than the NOb-G (P < 0.05). DH was more common in the Ob-G (72.2%) than in the NOb-G (38.9%, P < 0.05). The Ob-G had a greater reduction in the inspiratory capacity (-18 vs. -4.6%, P < 0.05). Exercise tolerance was associated with quadriceps endurance (r = 0.65; p < 0.001), oxygen pulse (r = 0.52; p = 0.001), and DH (r = -0.46, P = 0.005). The multiple regression analysis showed that the exercise tolerance could be predicted from a linear association only for muscular endurance (r = 0.82 and r(2) = 0.67). This study shows that dynamic hyperinflation is a common condition in obese asthmatics; they have reduced fitness for activities of daily living compared to nonobese asthmatics. However, peripheral limitation was the main factor associated with reduced capacity of exercise in these patients. NEW & NOTEWORTHY This is the first study to investigate the occurrence of dynamic hyperinflation (DH) in obese asthmatics. Our results demonstrate that obese asthmatics present a higher frequency and intensity of DH than nonobese asthmatics. We also show that physical deconditioning in this population is linearly associated with cardiac (O-2 pulse), respiratory (DH), and peripheral muscle (resistance) limitation. However, multiple linear regression demonstrated that peripheral muscle limitation may explain the exercise limitation in this population.
- Exercise Improves Physical Activity and Comorbidities in Obese Adults with Asthma(2018) FREITAS, Patricia Duarte; SILVA, Aline Grandi; FERREIRA, Palmira Gabriele; SILVA, Analuci Da; SALGE, Joao Marcos; CARVALHO-PINTO, Regina Maria; CUKIER, Alberto; BRITO, Claudia M.; MANCINI, Marcio C.; CARVALHO, Celso R. F.Introduction 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 physical activity levels in obese adults with asthma have been poorly investigated. Objective This study aimed to assess the effects of exercise on DLPA, asthma symptoms, and psychosocial comorbidities in obese adults with asthma. Methods Fifty-five grade II obese adults with asthma were randomly assigned to either a weight loss program + exercise program (WL + E group, n = 28) or a weight loss program + sham (WL + S group, n = 27). The WL + E group incorporated aerobic and resistance muscle training into the weight loss program (nutrition and psychological therapies), whereas the WL + S group performed breathing and stretching exercises. DLPA, asthma symptoms, sleep quality, and anxiety and depression symptoms were quantified before and after treatment. Results After 3 months, the WL + E group presented a significant increase in daily step counts (3068 2325 vs 729 +/- 1118 steps per day) and the number of asthma symptom-free days (14.5 +/- 9.6 vs 8.6 +/- 11.4 dmonth(-1)) compared with the WL + S group. The proportion of participants 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 that in the WL + S group (P < 0.05). Significant improvements in 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. Conclusions Our results strongly suggest that exercise training plus a weight loss program improves DLPA, sleep efficiency, and depression and asthma symptoms in obese adults with asthma.
