Background and purpose Exercise adherence in general is reported to be problematic after cardiac rehabilitation. Additionally, vigorous exercise is associated with impaired exercise adherence. As high‐intensity interval training (HIT) is frequently used as a therapy to patients with coronary artery disease in cardiac rehabilitation, the objective was to assess long‐term exercise adherence following an HIT cardiac rehabilitation programme. Methods A multicentre randomized study was carried out. Eligible participants were adults who had previously attended a 12‐week HIT cardiac rehabilitation programme, as either a home‐based or hospital‐based HIT (treadmill exercise or group exercise). The primary outcome was change in peak oxygen uptake; secondary outcomes were self‐reported and objectively measured physical activity. Results Out of 83 eligible participants, 76 were available for assessment (68 men/8 women, mean age 59 (8) years) at a one‐year follow‐up. Peak oxygen uptake was significantly elevated above baseline values, (treadmill exercise: 35.8 (6.4) vs. 37.4 (7.4) ml kg −1 min −1 , group exercise: 32.7 (6.5) vs. 34.1 (5.8) ml kg −1 min −1 and home‐based exercise: 34.5 (4.9) vs. 36.7 (5.8) ml kg −1 min −1 at baseline and follow‐up, respectively), with no significant differences between groups. The majority of the participants (>90%) met the recommended daily level of 30 minutes of moderate physical activity. The home‐based group showed a strong trend towards increased physical activity compared with the hospital‐based groups. Discussion The results from this study have shown that both home‐based and hospital‐based HIT in cardiac rehabilitation induce promising long‐term exercise adherence, with maintenance of peak oxygen uptake significantly above baseline values at a one‐year follow‐up. The implication for physiotherapy practice is that HIT in cardiac rehabilitation induces satisfactory long‐term exercise adherence. Copyright © 2015 John Wiley & Sons, Ltd.
