Summary

Telerehabilitation has the potential to become an alternative attitude to outpatient cardiac rehabilitation. The aim of our study is to research the method of high-intensity interval training in the home environment using telerehabilitation. Investigators assume that the high-intensity interval training form of telerehabilitation, using a heart rate monitor as a tool for backing up training data, can improve physical fitness and lead to higher peak oxygen uptake as the traditional moderate-intensity continuous training. The study is designed as a monocentral randomized controlled trial at University Hospital Brno in the Czech Republic. After the coronary event, eligible patients will be randomly (in 1:1 ratio) separated into two groups: the experimental high-intensity interval training group and the moderate-intensity continuous control group. Both groups undergo a 12-week telerehabilitation training program with a 52-week follow-up period. The primary outcome observed will be the effect of intervention expressed by changes in peak oxygen uptake values.

Detailed description

The study relates to the previous study project CR-GPS, in which investigators proved the feasibility of cardiac telerehabilitation. The results showed that aerobic capacity and quality of life improved similarly in telerehabilitation and outpatient group of participating patients. During the research, investigators used the moderate-intensity continuous method. The present research focuses on high-intensity interval training, which presents comparable or even better results in cardiorespiratory condition effects and requires less time than a continuous method in patients with low or medium cardiovascular risk.

Conditions

• Coronary Artery Disease

Interventions

Type	Name	Description
BEHAVIORAL	High-Intensity Interval Training	Remotely monitored exercises will be performed at home. The high-intensity interval group warms-up for 5 minutes at moderate intensity (65-75% of maximal heart rate). After warm-up exercise, will continue in 4 minutes intervals at high-intensity to reach the target zone (85-95% of maximal heart rate) Each interval will be separated by 3 minutes of active recoveries (at 65-75% of maximal heart rate). The session ends with a 3-minute cool-down phase. Overall training exercise time will be 33 minutes - isocaloric compared to moderate-intensity continous training group. All participants will train using a heart rate monitor during each workout.
BEHAVIORAL	Moderate-intensity continuous training	Remotely monitored exercises will be performed at home. Patients in the moderate-intensity continuous training group will perform a 41-minute constant workout with an intensity of 65-75% of maximum heart rate, representing the same total training load as the high-intensity aerobic exercise group. All participants will train using a heart rate monitor during each workout.
