Molecular Transducers of Physical Activity Consortium (MoTrPAC) - Pediatric Protocol

The goal of the Molecular Transducers of Physical Activity Consortium (MoTrPAC) is to assess molecular changes that occur in response to physical activity (PA). To achieve this aim, studies will be conducted in adults and separately in children and adolescents. The UC Irvine MoTrPAC Pediatric Clinical Center oversees two interrelated study phases in children and adolescents: 1. A cross-sectional phase in which molecular transducers (obtained from blood sampling) are measured in response to an acute exercise challenge (n = 320); 2. An intervention phase is conducted as a mechanistic randomized controlled trial (RCT). Participants are recruited from the cross-sectional study phase and randomized to endurance exercise (EE) training (n = 120) or no exercise Control (n = 50) for a period of approximately 12 weeks.
