In this controlled trial, patients referred to post-myocardial infarction cardiac rehabilitation will be randomized to either interval or continuous training.
The trial would i) compare the acute effects of each exercise type on selected cardiovascular indicators; ii) compare the chronic effects of each exercise type on selected cardiovascular indicators; iii) provide information on the association between acute and chronic effects of each exercise type; iv) provide insight into possible mechanisms of effectiveness of each exercise type; v) identify the most safe and effective exercise type for patients with coronary artery disease.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Interval training group | Active Comparator | Patients to be randomized to the 'interval training group' will have exercise training sessions 3 times per week for a period of 12 weeks. During training, they will undergo interval exercise series composed of high-intensity intervals (80-90% of peak exercise performance) and low-intensity intervals (60-70% of peak exercise performance). |
|
| Continuous training group | Active Comparator | Patients to be randomized to the 'continuous training group' will have exercise training sessions 3 times per week for a period of 12 weeks. During training, they will undergo moderate continuous exercise training at 75% of peak exercise performance. |
