  1. The accelerated increase in lean Body Mass of pre-pubescent Japanese boys at 10 to 11 years of age.

    Article - En anglais

    The present study investigated changes in body composition in relation to growth to evaluate at what age Japanese children begin their pre-pubescent growth spurt.

    Children aged 9 were followed to age 10 (The age 9 group), and those aged 10 were followed to age 11 (The age 10 group).

    The increase in lean body mass per one-year increment of body height (delta LBM/deltaBH) in the age 10 boys group was significantly higher than that in the age 9 boys group.

    In both the age 9 and 10 boys groups, the high Body Mass Index (BMI) boys showed greater mean deltaLBM/deltaBH than that for the normal BMI boys.

    Our results of accelerated delta LBM/deltaBH from age 10 to 11 in Japanese boys hypothesize that an increase in LBM demonstrates pre-pubescent growth.
