Brief summary

1) The primary outcome is to assess the immediate benefits (patient outcomes, health care utilisation costs, program uptake, adherence, and compliance) and longer term benefits (readmission rates, length of hospital stay and time to return to work) of implementing an innovative exercise model (HITT) in cardiac rehabilitation patients compared to current practice. The hypothesis that HITT participants will achieve superior functional capacity changes and strength in 40 mins compared with 60 mins for the control group will be assessed. The hypothesis that it can be completed in less time and be more financially viable will also be assessed. This could lead to a change in rehabilitative exercise practice and positively impact costs associated with this high healthcare burden, whilst improving health service delivery and ultimately patient outcomes. 2) Secondary outcomes are to assess if HIIT using a 2x4 min dosage produces change in Vo2 peak comparable to previous RCTs within the literature.

Interventions

Supervised cardiac rehabilitation exercise program consisting of high intensity interval aerobic 40 mins performed twice weekly for 6 weeks. These will be held at the Robina Health Precinct gymnasium and will be integrated within the cardiac rehabilitation class. The classes will be supervised by a physiotherapist or Exercise Physiologist with Bachelor degrees or Masters Degree and a cardiac nurse. This will consist of a 5 min warm up, 2x4 mins on a treadmill or cycle ergometer at 85-90% VO2peak
