PURPOSE: This study aimed to examine whether heart rate variability (HRV) moderates the interaction between implicit attitude and antecedent cognitive appraisals (ACAs). METHODS: Young adults (N=314; 188 ♀, M age = 20.5 ± 1.2 yrs; BMI= 24.4 ± 3.8 kg·m-2) completed the Single-Category Implicit Association Test (SC-IAT), the Affective Exercise Experiences (AFFEXX) questionnaire, self-reported exercise frequency and duration, health fitness testing (1-min sit-ups, push-ups, 1-mile run), and measured HRV (root mean square of successive differences), assessed using an eMotion Faros monitor during a 7-min resting state. RESULTS: Hierarchical multiple linear regression analyses revealed that implicit attitude showed significant positive associations with self-reported PA frequency when ACAs, (specifically competence, empowerment, honor) were low and HRV was high. Additionally, implicit attitude was positively associated with push-up performance when competence was low and HRV was high. These findings suggest that, even in the absence of reflective evaluations of exercise, a high level of HRV can foster positive affective valuations toward PA, thereby promoting and maintaining PA behaviors. Our study offers a psychophysiological perspective on enhancing PA by suggesting that for individuals who struggle to engage in exercise due to a lack of subjective agency, interventions designed to enhance cardiorespiratory fitness can trigger intrinsic emotions, ultimately motivating greater participation in PA."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Predicting physical activity behavior by affective-reflective theory: a psychophysiological perspective with heart rate variability as a moderator"]}]}],"canonical_facts":{"dc:contributor":["Petruzzello, Steven J."],"dc:creator":["Chen, Junchi (Daniel)"],"dc:date":["2025-07-24","2025-08"],"dc:description":["Submission original under an indefinite embargo labeled 'Open Access'.
