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 .
Effects of Isolated Cycle Ergometer Training on Patients with Moderate-to-Severe Chronic Obstructive Pulmonary Disease
Background : Pulmonary rehabilitation ( PR ) programs are beneficial to patients with chronic obstructive pulmonary disease ( COPD ) , and lower-extremity training is considered a fundamental component of PR . Nevertheless , the isolated effects of each PR component are not well established . Objective : We aim ed to evaluate the effects of a cycle ergometry exercise protocol as the only intervention in a group of COPD patients , and to compare these results with a control group . Methods : 25 moderate-to-severe COPD patients were evaluated regarding pulmonary function , respiratory muscle strength , exercise capacity , quality of life and body composition . Patients were allocated to one of two groups : ( a ) the trained group ( TG ; n = 13 ; 6 men ) was su bmi tted to a protocol of 24 exercise sessions on a cycle ergometer , with training intensity initially set at a heart rate ( HR ) close to 80 % of maximal HR achieved in a maximal test , and load increase based on dyspnea scores , and ( b ) the control group ( CG ; n = 12 ; 6 men ) with no intervention during the protocol period . Results : TG showed within-group significant improvements in endurance cycling time , 6-min walking distance test , maximal inspiratory pressure and in the domain ‘ dyspnea ’ related to quality of life . Despite the within-group changes , no between-group significant differences were observed . Conclusion : In COPD patients , the results of isolated low-to-moderate intensity cycle ergometer training are not comparable to effects of multimodality and high-intensity training programs
