BODY COMPOSITION AND RESTING ENERGY EXPENDITURE IN CHILDREN WEIGHING 30KG AND SUMO WRESTLERS WEIGHING 100KG(<Special Issue>Whole-Body Coordination and Adaptability through a Perspective of Metabolic Function (Symposium of the 72^<nd> Meeting))

Abstract

In the present review, we hypothesized and demonstrated that (1) the total skeletal muscle mass and its distribution in adolescents (Tanner stage &ge; 2) was mostly similar to that in adults; (2) exercise training with an adequate diet led to an increase in both skeletal muscle mass and internal organ mass; and (3) although the organ tissue metabolic rate (kcal/day/kg) in children had increased due to the energy cost of growth and development, the high resting energy expenditure in college Sumo wrestlers (> 2000 kcal/day) can be attributed to the presence of a larger absolute amount of metabolically active tissue.
