Summary

The purpose of the study is to examine the effect of two different high intensity interval training (HIIT) prescription approaches on improving fitness, heart function, and the ability of the body's muscles to receive oxygen.

Conditions

• Cardiac Rehabilitation

Interventions

Type	Name	Description
OTHER	Progressive High Intensity Interval Training (PRO-HIIT)	Individual exercise training sessions, involving two weeks of moderate intensity continuous exercise and 10 weeks of interval exercise training. This protocol involves progression of training of 3 stages: 1) six high-intensity intervals (at an RPE of 15-18) of 1-min separated by five low-intensity intervals of 2-min; 2) three high-intensity intervals of 2-min separated by two low-intensity intervals of 4-min, and a further 2-min of low intensity following the last interval before cool-down; and 3) three high-intensity intervals of 3-min separated by two low-intensity intervals of 3-min, and a further 1-min of low intensity following last interval before cool-down.
OTHER	Constant High Intensity Interval Training (CON-HIIT)	Individual exercise training sessions, involving two weeks of moderate intensity continuous exercise and 10 weeks of interval exercise training. This protocol involves a constant protocol of training, including six high-intensity intervals (at an RPE of 15-18) of 1-min separated by five low-intensity intervals of 2-min.
