Brief summary
The first purpose of this study is to investigate the physiological changes of heart failure patients during cardiopulmonary exercise test with spot jogging and compare them with the standard stationary bike cardiopulmonary exercise test. The second one is to compare the effect between home-based cardiac rehabilitation using different step frequency and toe lift or not to adjust spot jogging intensity and outpatient center-based cardiac rehabilitation for heart failure patients.
Detailed description
This is a pilot, prospective, randomized controlled trial design. We will recruit 40 heart failure patients aged over 18 year-old who have completed stationary bike cardiopulmonary exercise test and was referred to phase II cardiac rehabilitation. After providing informed consent, participants will be randomly assigned to either the home-based cardiac rehabilitation group or the outpatient center-based cardiac rehabilitation group. All participants will undergo spot jogging cardiopulmonary exercise test and six-minute walking test. The home-based spot jogging cardiac rehabilitation group will receive exercise intensity guidance in the outpatient cardiac rehabilitation room for 30 minutes of spot jogging and treadmill exercise during the first, fourth, and seventh weeks, and will perform spot jogging for 30 minutes twice a week at home. The outpatient center-based cardiac rehabilitation group will perform stationary bike or treadmill exercise for 30 minutes twice a week in the outpatient cardiac rehabilitation room. Both groups will achieve their target heart rate or 13 in rating perceived exertion. After 18 exercise sessions, participants will undergo stationary bike exercise test and six-minute walking test again.
Interventions
OTHERCenter-based exercise training
All participants will undergo a spot jogging cardiopulmonary exercise test and a six-minute walking test. The outpatient center-based cardiac rehabilitation group will perform moderate-intensity stationary biking or treadmill exercise for 30 minutes, twice a week, under the supervision of a physical therapist in the outpatient cardiac rehabilitation room.
OTHERHome-based spot jogging
The home-based spot jogging cardiac rehabilitation group will receive exercise intensity guidance in the outpatient cardiac rehabilitation room for 30 minutes of spot jogging and treadmill exercise during the first, fourth, and seventh weeks. They will then perform moderate-intensity spot jogging at home for 30 minutes, twice a week, at a perceived exertion level of 13 out of 20 on the RPE scale.
