Exploring Prenatal Physical Activity at the “Postgenomic Turn”: A Transdisciplinary Journey

Abstract Within the life sciences, there has been a move away from genetic determinism toward an awareness of how the environment (from cellular to social) can impact gene expression and health outcomes. Significantly, exercise scientists are looking to this “postgenomic turn” to explore how prenatal physical activity and leisure might affect the fetal metabolic environment by altering offspring gene expression and preventing future obesity. In this article, we draw upon insights from feminist new materialist scholars to explore how and if the entanglement of the social and material promised by the postgenomic turn is realized in prenatal exercise interventions. After outlining how this is not the case, we reflect upon our attempt to promote a transdisciplinary dialogue that facilitates a social justice ethos and nonreductionist version of maternal-fetal health and physical culture. Our transdisciplinary journey contributes to the feminist physical cultural studies agenda of equity development in the realm of exercise and leisure.
