Abstract The aim of this study was to determine effects of PR in asthmatic patients. Forty five patients with asthma (mean age: 44,5±]3,8; 32m/13f; FEV1 = 68,7±]13,6% pred.; asthma medication low/medium/high = 23/17/5) were included in the training group. PR was performed three times a week and included a cycle ergometer training (at 50-60% VO2max), diaphragmatic breathing with progressive muscle relaxation, gymnastics, manual massage, body vibration (frequency from 14 to 100 Hz (regime [dsquote]wave[dsquote]), during 10 min) and education support. Twenty patients served as controls (mean age: 39,2±]9,5; 14 m/4 f) and had a formal medical treatment. Pulmonary function (flow-volume curve, bodyplethysmography), ergospirometry and Borg scale for dyspnoea were evaluated before and after 8 weeks PR. Results: Raw decreased from 3,71±]0,21 to 3,13±]0,23 cmH2O/l (p<0,01). Exercise-induced asthma decreased from –18,7±]1,6% (FEV1 %) to –9,5±]1,2% (p<0,001). Effectiveness of ventilation during submaximal exercise (reduction of VEmax, l/min; VeqO2, [dsquote]index dyspnoea[dsquote] ) improved significantly (p<0,05) after PR. Exercise tolerance (VO2max/kg, PWC150) increased significantly (p<0,01) and Borg scale (6,6±]1,1 vs 5,2±]1,3; p<0,05) was reduced. In most cases in the training group changes were significantly different compared with baseline and control group. We conclude that PR improves pulmonary function and exercise tolerance, reduces bronchial hyperreactivity in asthmatic patients.
