Molecular Transducers of Physical Activity Consortium (MoTrPAC) Progress and Study Protocol Design

摘要

Physical activity is beneficial to human health and wellbeing across the lifespan. The numerous benefits of regular physical activity (PA) have long been recognized. Despite this, most exercise studies are associational and the molecular mechanisms that are the bases for the beneficial effects remain obscure as are the mechanisms of multiorgan communications and benefits. MoTrPAC is a large NIH discovery project (19 grants; 37 Principal Investigators; 23 institutions) whose goals are to assemble a comprehensive map of the molecular changes that occur in response to exercise and provide insights into how they are altered by age, sex, body composition and fitness level and develop a user-friendly database to facilitate investigator-initiated studies and catalyze the field of PA research and explore hypotheses exploring novel mechanisms by which PA improves or preserves health.
