This study will examine race differences in total energy expenditure and respiratory quotient (RQ) during and after exercise, compared to a sedentary control condition, in adolescent girls who are classified as overweight. In addition, subjective appetite and objective energy intake will be measured throughout the assessment periods.
Aim 1: Measure 24-hour energy expenditure and its components (resting, activity, and sleep energy expenditure) and compare differences between African-American and White girls.
Hypothesis: Total, resting, and sleep energy expenditure will be lower in African-American relative to White girls. Activity energy expenditure will be equivalent per the study design.
Aim 2: Measure and compare substrate oxidation and associations with appetite (i.e., hunger, desire to eat) and energy intake between African-American and White girls.
Hypothesis: African-American girls will have a higher RQ at rest, during exercise, and following exercise, and RQ will be positively associated with subjective appetite ratings and energy intake.
