Temporal Self-Regulation theory: A neurobiologically informed model for physical activity behavior

Dominant explanatory models for physical activity behavior are limited by the exclusion of several important components,including temporal dynamics,ecological forces,and neurobiological factors. the latter may be a critical omission,given the relevance of several aspects of cognitive function for the self-regulatory processes that are likely required for consistent implementation of physical activity behavior in everyday life. this narrative review introduces temporal self-regulation theory (tst; hall and fong,2007,2013) as a new explanatory model for physical activity behavior. important features of the model include consideration of the default status of the physical activity behavior,as well as the disproportionate influence of temporally proximal behavioral contingencies. most importantly,the tst model proposes positive feedback loops linking executive function (ef) and the performance of physical activity behavior. specifically,those with relatively stronger executive control (and optimized brain structures supporting it,such as the dorsolateral prefrontal cortex (pfc)) are able to implement physical activity with more consistency than others,which in turn serves to strengthen the executive control network itself. the tst model has the potential to explain everyday variants of incidental physical activity,sport-related excellence via capacity for deliberate practice,and variability in the propensity to schedule and implement exercise routines. © 2015 2015soh,skocic,nash,stevens,turnerandrovet.
