Exploring determinants of recalled in-task affective valence during recreational exercise

Exercise-related affective responses, particularly in-task, have been implicated as influencing behavioral maintenance. An extensive body of literature, primarily using aerobic modes in laboratory settings, has identified a relatively consistent inverse relationship between intensity and affect. This relationship is purported to be partially accounted for by the saliency of interoceptive sensations (i.e., respiratory and heart rates, muscular effort), such that increased saliency elicits decreased affect. In naturalistic settings, exercise is volitional, individuals have comparatively more autonomy over exercise components (i.e., volume, duration, exercise intensity), and less is known regarding contributing factors of affective responses. Recalled affect may be perceived as a less invasive, more logistically feasible construct to measure in such settings. Thus, the purpose of the current study is to explore the basis of recalled affective valence following an acute bout of volitional exercise. Upon leaving the designated exercise area of a university recreation center, respondents (N = 236, 23y±10, 176cm±9.5, 76.9kg±16.2, 31.8% identified women, 68.2% identified men) were asked to complete a pen-and-paper survey regarding the bout they had just completed. Recalled affective valence was rated via 100 mm Visual Analog Scale, and respondents were asked to provide written explanation for the basis of recalled affective valence scores. Recalled affective valence scores were non-normally distributed (Mdn=81; IQR=30.5). Qualitative results indicate that interpretation of exertion and salient interoceptive sensations were mixed, resulting in both pleasant and unpleasant affective responses. Pre-exercise readiness factors (i.e., energy levels, substrate intake, and physical components) also contribute to recalled affective valence and could potentially explain variance in the interpretation of interoceptive sensations. Further research should expand on these findings through a more in-depth interview process and measuring factors of readiness before exercise.
