ALVES, Fabrício B. et al. Analysis of adiposity and physical fitness indexes in prepubertal children. Rev. Port. Cien. Desp. [online]. 2008, vol.8, n.1, pp.85-95. ISSN 1645-0523.

The purpose of this study was the to assess physical fitness in prepubertal children aged 8-11 years old and , and by gender (32 boys and 35 girls) to analyze the relationships between adiposity indexes. The drawings of self-assessment modified by Faulkner were used to assess the stage of sexual maturation. Fat percentage was calculated by Boileau et al. equations, waist and hip perimeters were collected by Callaway et al. standardization. Sit-and-reach test and hand grip tests were performed according to Johnson and Nelson and Safrit. VO2_max estimation was had using 20-m Shuttle Run test developed by Léger et al.. As a result, there were significant correlations (p<0.05) among BMI, fat percentage and waist and hip perimeter. BMI awareness was best predicted (89.7%) by fat percentage, lean body mass and age. The obtained lean body mass was different between sexes (p<0.05). Scientific outcomes for boys presented lower level of flexibility (p>0.05); higher levels of handgrip strength and VO2 max (p<0.05). Sharply, maturational stage and sex should be considered in the analysis of adiposity and fitness in children.
