Comparison Between HIIT and MICT on the Phase III of Cardiac Rehabilitation

"The HIIT group performed 4 × 4-minute high-intensity intervals at 85%-95% HRpeak followed by a 1-minute recovery interval at 40% HRpeak, predicted with a supervised graded exercise test on a treadmill with the Bruce protocol. The protocol will include a warm-up of 10 minutes at low moderate intensity (50-70% of HRpeak) and a 3 to 5 minute calm return period at 50% of the HRpeak.~The supervised sessions will take place on treadmill, 3 times a week for 6 consecutive weeks. If a session is lost, it will be recovered that week or the following week. Each session will be limited to three participants."

"The MICT protocol (usual care) consisted of a continuous bout of moderate-intensity exercise to elicit 70-75% HRpeak, rating of perceived exertion 3 to 5 (fairly light to somewhat hard), for 27.5 minutes to equate the energy expenditure with the HIIT protocol. The protocol will include a warm-up of 10 minutes at low moderate intensity (50-70% of HRpeak) and a 3 to 5 minute calm return period at 50% of the HRpeak.~The supervised sessions will take place on treadmill, 3 times a week for 6 consecutive weeks. If a session is lost, it will be recovered that week or the following week. Each session will be limited to three participants."
