Abstract

The study deals with the connection between sexual maturation and fat accumulation during male puberty. The purposes were: (1) to follow the alterations in regional body adiposity during genital development; (2) to reveal the differences in fat patterning of athletes and non-athletes, (3) to analyze the influence of genital maturation and sport activity on the indices of fatness in pubertal boys. The subjects were athlete (n=803) and non-athlete (n=989) boys. They were grouped by the stages of genital development. Regional fat distribution was examined on the basis of skinfolds. The amount of subcutaneous and visceral abdominal adipose tissues was assessed by regression equations of Brambilla and co-workers. The effect of genital development and sport activity on fat compartments was studied by multivariate ANOVA. The centralization tendency in adipose tissue was revealed by the progressing of genital development. Non-athletes accumulated more relative subcutaneous fat on their extremities, while athletes did it on their trunk. Adjusted to the absolute body fat mass, visceral adipose tissue increased faster in athletes than in non-athletes. The multivariate model proved that genital maturation affected the regional fat distribution. During sexual maturation the regional apposition trend of body fat was similar for athletes and non-athletes. The differences between athletes’ and non-athletes’ fat pattering emerged in the relative distributions. The relatively thicker fat layer on the trunk served better the extended energy supply for athletes. The effect of sexual maturation was the largest on the visceral adipose tissue, while sport activity influenced the subcutaneous adipose tissue better on the extremities.
