Preliminary evidence suggests that children may report decreasing pleasure throughout incremental exercise tests. This pattern of affective responses might be related to the deviation of incremental and prolonged patterns of exercise from the innate propensity of children for intermittent movement. Furthermore, the self-regulation of affective responses during exercise may require cognitive strategies underpinned by cortical networks still under development during childhood. Consequently, the purpose of this study was to examine (1) whether dorsolateral prefrontal cortical (dlPFC) activity is associated with affective responses during an incremental cycling exercise test, and (2) whether theoretically relevant covariates moderate affective responses and dlPFC activation ...
