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 .
A Simple Method for Home Exercise Training in Patients With Chronic Obstructive Pulmonary Disease: ONE-YEAR STUDY
PURPOSE : The success of long-term exercise training ( ExT ) programs resides in the integration between exercise prescription and patient compliance with home training . One of the crucial issues for the patients is the underst and ing of appropriate exercise intensity . We compared 2 methods of home ExT , based on walking . METHODS : Forty-seven patients with chronic obstructive pulmonary disease were recruited and underwent respiratory function , exercise capacity evaluation with a 6-minute walk test , and treadmill tests . Physical activity was monitored by a multisensor Armb and ( SenseWear , Body Media , Pittsburgh , PA ) . Patients were r and omly assigned to 2 different home training methods and assessed again after 6 and 12 months ; group A1 : speed walking paced by a metronome , and group A2 : walking a known distance in a fixed time . RESULTS : Thirty-six patients completed the study . All subjects showed a significant improvement in the 6-minute walk test after 1 year but the improvement was higher in A1 than in A2 ( P < .05 ) . Physical activity levels were significantly higher at T12 versus baseline only in group A1 ( P < .05 ) . CONCLUSIONS : The use of a metronome to maintain the rate of walking during home ExT seems to be beneficial , allowing patients to achieve and sustain the optimal exercise intensity , and result ing in greater improvement compared to simply using a fixed time interval exercise
