Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is the aim of our study to compare the effects of 6 and/or 2 years of either HIT (carried out at correctly assessed 85-95% of maximal heart rate), pyramid, or continuous endurance training, on changes of physical exercise capacity in cardiac patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The three exercise arms (isocaloric) are composed as follows:

Endurance training: 31 min at 65-75% HRmax, making it a total of 25min; HIT: 4x4min intervals at 85-95% HRmax divided by 3x3min of active recovery at 60-70% HRmax, making it a total of 25 min; Pyramid: One pyramid consists of 8 one-minute blocks. Those are grouped starting with one block of 70-75% HRmax, followed by one block at 75-80% HRmax and another one at 80-85% HRmax. The top of the pyramid are 2 blocks of 85-90% HRmax. Intensity is lowered afterwards with one block of 80-85% HRmax, followed by one block at 75-80% HRmax and last one at 70-75% HRmax. Two more pyramids follow, each divided by 2min of active recovery at 65-70% HRmax, making it a total of 28min.

All protocols are initiated by 5min of warm-up and end with 5min of cool-down, both at 60-70% HRmax.

Primary Outcome: Individual maximum power output in watt (Pmax). Secondary Outcome: Change of power output in watt at lactate tresholds at 2 and 4mmol/l.
