Peanut Protein Supplementation to Augment Muscle Growth and Improve Markers of Muscle Quality and Health in Young Adults
Peanut Protein Supplementation to Augment Muscle Growth and Improve Markers of Muscle Quality and Health in Young Adults
This study will evaluate the adaptations in skeletal muscle that occur in response to 10
 weeks of weight training with or without peanut protein supplementation in untrained men and
 women ages 18-30
This is a two-phase study using both novel and conventional methods to assess how PP
 supplementation affects muscle tissue in young adults who engage in resistance training.
 These two phases will be conducted as part of a 10-week randomized controlled trial in which
 men and women aged 18-30 years (n=40), will be stratified by gender and randomized to a
 resistance training intervention (whole body, two days per week) with PP powder (72g daily;
 n=10 males, n=10 females) provided during the intervention (immediate group, IG) or after the
 intervention (wait-list control, WLC, n=10 males, n=10 females). The aims of this study are
 to determine the acute (deuterium oxide tracer) and chronic (peripheral quantitative computed
 tomography) effects of PP during resistance training on skeletal muscle myofibrillar protein
 synthesis rates, changes in skeletal muscle size and quality, changes in whole and
 appendicular body composition (dual energy x-ray absorptiometry), changes in inflammatory
 markers and the fecal microbiome.
