International Journal of Exercise Science: Conference Proceedings
Epinephrine is a catabolic hormone that increases metabolism through glycolysis and glycogenolysis. During exercise, accelerated glycogen and glucose breakdown is associated with increased lactate production. Previous studies show obesity (OB) decreases the epinephrine response during exercise potentially affecting glucose metabolism and lactate production. PURPOSE: To compare the epinephrine and lactate responses in adolescents with OB and adolescents with normal weight (NW) and to determine if changes in epinephrine and lactate concentrations are associated. METHODS: 12 adolescents with OB (9.2 ± 1.2 y, 39.9 ± 6.8% body fat) and 12 adolescents with NW (17.5 ± 4.6% body fat) completed …
