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.
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.
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.
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.
据报道，心脏康复后总体运动依从性存在问题。此外，剧烈运动与运动依从性受损有关。由于高强度间歇训练（HIT）在心脏康复中经常被用作治疗冠心病患者的方法，目的是评估HIT心脏康复计划后的长期运动依从性。
进行了一项多中心随机研究。符合条件的参与者是之前参加过为期12周的HIT心脏康复计划的成年人，该计划可以是居家或医院的HIT（跑步机运动或团体运动）。主要结局是峰值摄氧量的变化；次要结局是自我报告和客观测量的身体活动。
在83名符合条件的参与者中，76人在一年随访时可进行评估（68名男性/8名女性，平均年龄59（8）岁）。峰值摄氧量显著高于基线值（跑步机运动：基线时和随访时分别为35.8（6.4）与37.4（7.4）ml·kg⁻¹·min⁻¹，团体运动：32.7（6.5）与34.1（5.8）ml·kg⁻¹·min⁻¹，居家运动：34.5（4.9）与36.7（5.8）ml·kg⁻¹·min⁻¹），组间无显著差异。大多数参与者（>90%）达到了建议的每日30分钟中等强度身体活动水平。与医院组相比，居家组的身体活动有增加的强烈趋势。
本研究结果表明，心脏康复中的居家和医院HIT均能诱导出有前景的长期运动依从性，在一年随访时峰值摄氧量维持在显著高于基线值的水平。对物理治疗实践的启示是，心脏康复中的HIT能诱导出令人满意的长期运动依从性。
