Abstract

in AERO-LBAT; p = 0.004). Carbohydrate oxidation displayed a characteristic biphasic decline but showed no significant differences between groups. In contrast, lipid oxidation peaked later and was substantially higher in the HBAT groups, with the most pronounced effect following HIIE. Protein oxidation remained minimal and consistent across all conditions. These findings demonstrate that elevated BAT activity is associated with increased exercise-induced energy expenditure and enhanced lipid utilization during the latter stages of exercise, with HIIE showing the most robust metabolic associations in individuals with high BAT activity.
