Abstract
<p><strong>Background</strong>: Aerobic capacity has been shown to be inversely proportionate to cardiovascular mortality and morbidity and there is growing evidence that high-intensity interval training (HIIT) appears to be more effective than moderate-intensity continuous training (MICT) in improving cardio-respiratory fitness within the cardiac population. Previously published systematic reviews in cardiovascular disease have neither investigated the effect that the number of weeks of intervention has on cardio-respiratory fitness changes, nor have adverse events been collated.</p>
<p><strong>Objective</strong>: We aimed to undertake a systematic review and meta-analysis of randomized controlled trials (RCTs) within the cardiac population that investigated cardio-respiratory fitness changes resulting from HIIT versus MICT and to collate adverse events.</p>
<p><strong>Methods</strong>: A critical narrative synthesis and meta-analysis was conducted after systematically searching relevant databases up to July 2017. We searched for RCTs that compared cardio-respiratory fitness changes resulting from HIIT versus MICT interventions within the cardiac population.</p>
<p><strong>Results</strong>: Seventeen studies, involving 953 participants (465 for HIIT and 488 for MICT) were included in the analysis. HIIT was significantly superior to MICT in improving cardio-respiratory fitness overall (SMD 0.34 mL/kg/min; 95% confidence interval [CI; 0.2–0.48]; p</p>
<p><strong>Conclusion</strong>: HIIT is superior to MICT in improving cardio-respiratory fitness in participants of cardiac rehabilitation (CR). Improvements in cardio-respiratory fitness are significant for CR programs of >6-week duration. Programs of 7–12 weeks’ duration resulted in the largest improvements in cardio-respiratory fitness for patients with coronary artery disease. HIIT appears to be as safe as MICT for CR participants</p>
