The effects of HIIT appear to be comparable to those of continuous exercise in relation to functional and cardiovascular responses .
OBJECTIVE To evaluate the effects of high-intensity interval training ( HIIT ) , in comparison with those of continuous exercise , on functional capacity and cardiovascular variables in patients with COPD , through a systematic review and meta- analysis of r and omized controlled trials .
Interval Training Versus Continuous Training in Patients With Chronic Obstructive Pulmonary Disease
PURPOSE The purpose of this study was to compare the effects of interval training ( IT ) and continuous steady-pace training ( CT ) in patients with COPD . METHODS Patients ( n = 21 ) ( mean forced expiratory volume in 1 second ( [ FEV1 ] = 44.6 % ± 13.9 % ) were r and omized to IT , and 20 patients ( mean FEV1 = 41.7 % ± 12.6 % ) to CT . Outcome measures included 6-minute walk distance , maximal work capacity , endurance exercise time during constant workload exercise at 60 % to 70 % of maximal work capacity , and quality of life including fatigue and dyspnea . Participants exercised 3 times per week for 8 weeks , and total work was the same for both training regimens . RESULTS Significant improvement in mean score was observed in each variable within each of the 2 groups : 6-minute walk distance ( IT = 158 ± 178 ft , CT = 106 ± 165 ft ) ; maximal work capacity ( IT = 10.0 ± 13.0 W , CT = 11.5 ± 13.1 W ) ; endurance exercise time ( IT = 15.0 ± 12.5 minutes , CT = 18.7 ± 10.6 minutes ) ; and quality of life domains , fatigue ( IT = 3.1 ± 3.0 , CT = 2.8 ± 4.7 ) , and dyspnea ( IT = 4.4 ± 5.3 , CT = 5.4 ± 5.1 ) . There was no significant difference in the extent of improvement between the 2 training regimens for any of the outcome variables . CONCLUSION Compared with CT , IT was well tolerated and produced similar improvements in exercise performance and quality of life
