Little information is available on energy metabolism during exercise in girls, particularly the contribution of exogenous carbohydrate (CHO(exo)). The purpose of this study was to determine substrate utilization during exercise with and without CHO(exo) intake in healthy girls. Twelve-yr-old preadolescent (YG; n = 12) and 14-yr-old adolescent (OG; n = 10) girls consumed flavored water (WT) or (13)C-enriched 6% CHO (CT) while cycling for 60 min at approximately 70% maximal aerobic power (Vo(2max… CONTINUE READING
