AIMS
Interoception is the sensing function of physiological conditions and is crucial in self-regulation and decision-making. We examined the association of heartbeat tracking task performance, an indicator of interoceptive accuracy, with the degree of improvement in exercise tolerance in patients undergoing home-based cardiac rehabilitation.
METHODS AND RESULTS
Participants underwent baseline peak oxygen uptake (VO) measurements and a heartbeat tracking task. The heartbeat tracking task score varies between 0 and 1, with higher scores indicating a better heartbeat perception. After 6 months of home-based exercise training, peak VO was measured again, and the percentage change (%Δ peak VO) relative to the peak VO at baseline was calculated. Univariate regression analysis was performed to examine the association between %Δ peak VO and the heartbeat tracking task score. Multiple regression analysis was performed to determine the predictors of %Δ peak VO. Of 120 participants, 100 patients (age 65.9 ± 11.9 years; 86% male) were included. There was a significant positive association between %Δ peak VO and the heartbeat tracking task score at baseline ( = 0.236, < 0.001). In multiple regression analysis, the percentage of measured peak VO to the predicted value (%predicted peak VO) ( = -0.248, = 0.002), exercise adherence ( = 0.364, < 0.001), and heartbeat tracking task score at baseline ( = 0.372, < 0.001) were significantly associated with %Δ peak VO.
CONCLUSIONS
Heartbeat tracking task performance, an indicator of interoceptive accuracy, at baseline is associated with the degree of improvement in exercise tolerance.
目的
内感受是对生理状态的感知功能，在自我调节和决策中至关重要。我们研究了心跳追踪任务表现（内感受准确性的一个指标）与接受家庭心脏康复治疗患者运动耐量改善程度之间的关联。
方法与结果
参与者进行了基线峰值摄氧量（VO）测量和心跳追踪任务。心跳追踪任务得分在0到1之间变化，得分越高表明心跳感知越好。经过6个月的家庭运动训练后，再次测量峰值VO，并计算相对于基线峰值VO的百分比变化（%Δ峰值VO）。进行单变量回归分析以检验%Δ峰值VO与心跳追踪任务得分之间的关联。进行多变量回归分析以确定%Δ峰值VO的预测因素。在120名参与者中，纳入了100名患者（年龄65.9±11.9岁；86%为男性）。基线时%Δ峰值VO与心跳追踪任务得分之间存在显著正相关（ = 0.236， < 0.001）。在多变量回归分析中，实测峰值VO占预测值的百分比（%预测峰值VO）（ = -0.248， = 0.002）、运动依从性（ = 0.364， < 0.001）和基线时的心跳追踪任务得分（ = 0.372， < 0.001）与%Δ峰值VO显著相关。
结论
基线时心跳追踪任务表现（内感受准确性的一个指标）与运动耐量的改善程度相关。
