Patients with asthma moderate and severe presents reduced moderate levels of physical activity, less aerobic conditioning and poorly control of the asthma

Abstract

The levels of physical activity are extensively studied in COPD than in asthmatic patients. Aim: Quantify the moderate levels of daily physical activity in patients with moderate and severe asthma. Methods: 24 asthmatic patients (F=21; M=3) treated at least 5 years in a department of pneumology and without using oral corticosterone and at least one month were chosen. Outcomes: lung function, clinical control (by ACT and ACQ-6), VO2peak (cardiopulmonary exercise test), levels of physical activity quantified by a week (accelerometer). Results: FEV1(L) (1.93±0.57), FVC(L) (2.81±0.81), FEV1/FVC (L) (0.69±0.06), Age (Yrs) (44.9±9.4); BMI (29.0±3.54 kg/m2); ACT (17.3±4.57); ACQ-6 (1.69±1.18); VO2peak (20.0±4.23 ml.kg.min), Classification of maximal aerobic capacity (Very Poor =79.16%; Poor= 16.6%; Fair= 4.16%); Power walking (moderate intensity) performed (4988.2±1481.3 step/day), Time of moderate walking (47.9±43.2), Classification: 100 min= 0%; Total step (low intensity) (12198.6±3551.95 step/day), Classification by total steps per day: Sedentary 12.500= 29.1%. Conclusion: The asthmatic patients that presents very low levels of vigorous physical activity during your daily routine also had a low cardiopulmonary capacity, which seems to contribute to the difficult the asthma control. These patients should be encouraged to participate in a rehabilitation program to increase their daily moderate level of physical activity.
