Sex differences in plasma amino acid and fat free mass responses to military training
Abstract
Diet, exercise, and energy status influence amino acid (AA) availability and contribute to the regulation of skeletal muscle mass. Whether altering these factors through training influence plasma AA levels and the maintenance of muscle mass in young adults has not been determined. This study assessed body composition and plasma AA levels in US Army recruits (n=209, 118 males, 91 females, 23 ± 5 yr) at baseline and every three weeks during basic combat training (BCT). Body weight decreased in men but remained stable in women during BCT (sex‐by‐time interaction, P P P P P P P P < 0.05) increases in AA concentrations observed for those who gained FFM. This data demonstrates the differential FFM and plasma AA responses to military training in males and females. Supported by USAMRMC.
