Summary

Heart rate variability (HRV) is impaired in patients after myocardial infarction. Most studies so far have proved chronic beneficial effects of different types of exercise on HRV parameters. Data on acute effects of different types of exercise training (e.g. high intensity interval training \[HIIT\] and moderate intensity continuous training \[MICT\]) is scarce. Patients in the study will perform both HIIT and MICT in a random order and in-between break of at least 48 hours. A 5-minute high resolution ECG recording will be performed before and immediately after both HIIT and MICT.

Conditions

• Myocardial Infarction

Interventions

Type	Name	Description
OTHER	Type of Exercise	The high-intensity interval training session consists of 5-min warm-up and 5-min cool-down periods. The main part has 7 cycles. Each cycle consists of 1.5 min of 80-90% of HRpeak and 3 min of 65-70% of HRpeak. The moderate-intensity continuous training session consists of 5 min warm-up and 3-min cool down period. The main part consists of 32 min of 75% of HRpeak.
