Genetic Variations in the Dopaminergic Reward System Are Associated with Exercise Reinforcement (P16-013-19)

ABSTRACT: Abstract

Objectives

This study tested whether genotypes previously identified as moderators of other reinforcing behaviors, such as eating and drug abuse, also influence exercise reinforcement and the choice to exercise, measured as the reinforcing value of exercise relative to sedentary activities (screen time, reading, etc.). Linking specific genetic signatures of central mechanisms of reinforcement with an individual's exercise reinforcement has yet to be investigated and may uncover central mechanisms that underlie individual differences in exercise motivation, usual exercise behavior and long-term exercise adherence. Since preference and tolerance for exercise intensity influences exercise reinforcement, genetic contributions of these individual characteristics were also eval
