The research will study the differences between interval training and continuous training among cardiac patients in a cardiac rehabilitation facility.

The main objectives are:

1. Functional capacity measures (VO2 max).
2. Cardiac risk factors
3. Quality of life assessments.

Study hypothesis:

Interval training will be more effective in improving functional capacity, cardiac risk factors and quality of life, compared to continuous training.
