Energy expenditure and physical fitness in overweight vs non-overweight prepubertal girls.

摘要: OBJECTIVE: To determine whether overweight children have lower physical activity energy expenditure (EE) and fitness levels than non-overweight children. STUDY DESIGN: Twenty-four healthy girls aged 7‐10 y were divided into (> 95th percentile weight-forheight) (10‐90th percentile) groups. Basal metabolic rate (BMR), sleeping (SMR), 24 h sedentary EE (SEE) total (TEE) measured by room respiration calorimetry doubly labelled water. Physical level (PAL) calculated. Fitness (VO2peak) was a treadmill exercise test. RESULTS: The group had significantly higher body weight, percent fat, fat mass fat-free (FFM) (P< 0.001). BMR, SMR, SEE TEE 0.001), but not after adjustment for FFM. PAL different between After adjusting FFM or submaximal peak VO2 CONCLUSIONS: We conclude that these do the prepubertal girls, however, rather high of may precluded us from finding any differences
