The aim of this study was to investigate short- and long-term compensatory effects on dietary intake following high intensity interval training (HIIT) compared with usual care moderate intensity continuous training (MICT) during and following a cardiac rehabilitation program. This study investigates secondary outcomes of a clinical trial. Ninety-three participants with coronary artery disease enrolled in a 4-week cardiac rehabilitation program, were randomised to 1) 4x4-minute HIIT; or 2) 40-min of MICT (usual care). Patients were instructed to complete 3 weekly sessions (2 supervised, 1 home-based) for 4-weeks, and 3 weekly home-based sessions thereafter for another 48-weeks. Dietary intake was measured by telephone-based 24-h recall over 2 day at baseline, 4-weeks, 3-months, 6-months, and 12-months. Three-Factor Eating Questionnaire was used to measure dietary behaviour and Leeds Food Preference Questionnaire used to measure food preferences. Appetite was assessed by a visual analogue scale and appetite-regulating hormones. There was no change over the study period or differences between groups for daily energy intake at 4-weeks or 12-months. There were also no group differences for any other measures of dietary intake, fasting hunger or appetite-related hormones, dietary behaviour, or food preferences. These findings suggest that compared to moderate intensity exercise, HIIT does not result in compensatory increases of energy intake or indicators of poor diet quality. This finding appears to be the same for patients with normal weight and obesity. HIIT can therefore be included in cardiac rehabilitation programs as an adjunct or alterative to MICT, without concern for any undesirable dietary compensation.
本研究旨在调查高强度间歇训练(HIIT)与常规中等强度持续训练(MICT)相比,在心脏康复计划期间和之后对饮食摄入的短期和长期补偿效应。本研究调查了一项临床试验的次要结果。93 名患有冠状动脉疾病的参与者参加了为期 4 周的心脏康复计划,他们被随机分为 1)4x4 分钟 HIIT;或 2)40 分钟 MICT(常规护理)。患者被指示在 4 周内完成 3 次每周的课程(2 次监督,1 次家庭),之后再进行另外 48 周的 3 次每周家庭课程。通过电话进行 24 小时回顾,在基线、4 周、3 个月、6 个月和 12 个月时测量饮食摄入。使用三因素饮食问卷测量饮食行为,使用利兹食物偏好问卷测量食物偏好。通过视觉模拟量表评估食欲,通过食欲调节激素评估食欲。在研究期间,每日能量摄入量在 4 周或 12 个月时没有变化,两组之间也没有差异。在任何其他饮食摄入、空腹饥饿或与食欲相关的激素、饮食行为或食物偏好的测量方面,两组之间也没有差异。这些发现表明,与中等强度运动相比,HIIT 不会导致能量摄入或不良饮食质量指标的代偿性增加。对于正常体重和肥胖的患者,这一发现似乎也是如此。因此,HIIT 可以作为心脏康复计划的一种辅助手段或替代方案,与 MICT 一起使用,而不必担心任何不良的饮食补偿。
