Although self-efficacy (SE) is an important determinant of regular exercise, it is unclear how subjective and physiological states before, during, and after the exercise session affects post-exercise SE. The aim of this study was to clarify subjective and physiological factors affecting post-exercise SE assessed after a single exercise session at a physiologically equivalent level. Forty-three healthy volunteers (28 women, 15 men) completed an 82-min experimental session, comprising a 22-min pre-exercise rest, a 30-min steady-state cycling exercise at moderate intensity [40% of heart rate (HR) reserve], and a 30-min post-exercise rest. We measured physiological (HR) and subjective [Rating of Perceived Exertion (RPE), Feeling Scale (FS)] states during the experimental session. Autonomic states were assessed by power spectral analysis of heart rate variability (HRV) during pre- and post-exercise rest. Post-exercise SE, which was the participants' confidence in their ability to perform the 30-min exercise that they had just performed, was assessed at 30-min post-exercise. A stepwise multiple regression analysis, with post-exercise SE as the dependent variable and physiological and subjective measures of the exercise as candidate explanatory variables, showed that post-exercise SE was negatively correlated with RPE and positively correlated with FS at the end of the 30-min exercise. In addition, post-exercise SE was negatively correlated with high-frequency power of the post-exercise HRV, an index of parasympathetic function. These results indicate that post-exercise SE is related not only to subjective responses to the exercise but also to autonomic response after the exercise.
尽管自我效能感（SE）是规律锻炼的一个重要决定因素，但尚不清楚锻炼前、锻炼期间和锻炼后的主观及生理状态如何影响锻炼后的自我效能感。本研究的目的是阐明在生理等效水平进行单次锻炼后评估的影响锻炼后自我效能感的主观和生理因素。43名健康志愿者（28名女性，15名男性）完成了一次82分钟的实验，包括22分钟的锻炼前休息、30分钟中等强度[心率储备（HR）的40%]的稳态骑行锻炼以及30分钟的锻炼后休息。我们在实验过程中测量了生理（心率）和主观[自感用力度（RPE）、感觉量表（FS）]状态。通过锻炼前和锻炼后休息期间心率变异性（HRV）的功率谱分析评估自主神经状态。锻炼后自我效能感是指参与者对自己完成刚刚进行的30分钟锻炼能力的信心，在锻炼后30分钟进行评估。以锻炼后自我效能感为因变量，锻炼的生理和主观测量指标作为候选解释变量进行逐步多元回归分析，结果显示，在30分钟锻炼结束时，锻炼后自我效能感与RPE呈负相关，与FS呈正相关。此外，锻炼后自我效能感与锻炼后HRV的高频功率呈负相关，高频功率是副交感神经功能的一个指标。这些结果表明，锻炼后自我效能感不仅与对锻炼的主观反应有关，还与锻炼后的自主神经反应有关。
