Interoception has been shown to influence self-regulation of effort and perceived exertion during exercise. However, whether interoceptive accuracy influences submaximal and maximal exercise performance, as well as psychophysiological responses to it, remains elusive. We assessed poor (n = 15) and good (n = 17) heartbeat perceivers young men accordingly with their interoceptive accuracy. Heart rate variability (HRV) and blood pressure were measured at rest, and peak power, ratings of perceived exertion (RPE), and HR during a maximal incremental test in a bicycle ergometer. Results: At rest, HR, diastolic and mean blood pressure was lower, and inter-beat intervals were longer for good heartbeat perceivers, with no difference in HRV. During exercise, good and poor heartbeat perceivers exhibited the same submaximal and maximal power, HR, RPE at submaximal intensity, and physical fitness. Interoceptive accuracy does not influence cardiac autonomic modulation perceptual responses and performance at submaximal and maximal intensities during maximal incremental exercise.
内感受已被证明会影响运动期间的努力自我调节和感知用力。然而，内感受准确性是否会影响次最大和最大运动表现以及对其的心理生理反应，仍不清楚。我们根据内感受准确性评估了较差（n=15）和较好（n=17）的心跳感知者年轻男性。在休息时测量心率变异性（HRV）和血压，并在自行车测力计上进行最大增量测试时测量峰值功率、感知用力等级（RPE）和心率。结果：在休息时，较好的心跳感知者的心率、舒张压和平均血压较低，心搏间期较长，而 HRV 无差异。在运动期间，较好和较差的心跳感知者在次最大强度和最大强度下表现出相同的次最大和最大功率、心率、RPE 和体能。在最大增量运动期间，内感受准确性不会影响次最大和最大强度下的心脏自主调节感知反应和表现。
