PURPOSE: The purpose of this study was to determine the effects of a school-based, low-volume strength training program on energy expenditure, strength, and physical fitness in @entity28 prepubertal @entity1 . METHODS: A longitudinal, 5-month strength training exercise program was undertaken by healthy, @entity28 (> 95th percentile weight-for-height, N = 11) @entity1 age 7-10 yr. The following were measured: strength by the one-repetition maximum test; fitness (VO2peak) by a treadmill exercise test; resting metabolic rate (RMR), 24-h sedentary energy expenditure (SEE), and sleeping metabolic rate (SMR) by room respiration calorimetry; and total energy expenditure (TEE) by the doubly labeled water method. Physical activity energy expenditure (AEE) was calculated as TEE-(RMR + 0.1.TEE) and @entity3457 ( @entity3457 ) as TEE/RMR. An age-matched, nonoverweight control group was measured for (VO2peak) and RMR over the same time period. RESULTS: Strength increased by 19.6 and 20.0% in the upper and lower body (P < 0.01), respectively. (VO2peak) (mL. @entity1009 ) increased in both groups over time (P < 0.05), but not when covaried @entity1386 ( @entity1386 ) or weight. After adjusting for @entity1386 or weight, RMR did not change, but SMR and 24-h SEE decreased significantly in the exercise group. There were no changes in nonprotein respiratory quotient or substrate oxidation. No changes in TEE, AEE, and @entity3457 occurred, either unadjusted or adjusted for @entity1386 or weight. CONCLUSION: This long-term, school-based, low-volume strength training program favorably increases strength in @entity28 prepubertal @entity1 but does not increase their daily energy expenditure.
