Higher Intensity Interval Training in Cardiac Rehabilitation

Practical Use of Higher Intensity Interval Exercise in Cardiac Rehabilitation to Improve Aerobic Fitness

The purpose of this study is to compare the effect higher intensity interval exercise (HIIT) with standard intensity non-interval exercise on fitness in cardiac rehabilitation patients with CAD. Also to assess practical implementation of HIIT in cardiac rehabilitation.
