Background and Study Aim: Many empirical data provides evidence that the correct, long combat sports training stimulates biological, mental and social human’s development. The research aimed is impact of systematic judo training on the dynamism of development processes in the youth during puberty.
Material and Methods: The research was of semi longitudinal (2-years) character: it was first-age of the subjects: 13, then repeated after one year – age of the subjects: 14 and next done after another year – age of the subjects: 15. One hundred sixty-two persons were studied: 88 females and 74 males; Research group: 8 females and 15 males practised judo, control group: 80 females and 59 males. Linear measurements to calculate the indices: RI,WHR, LLI, ULIWLI. Body weight of the subjects [kg] and body fat percentage evaluated using BIA method [FAT %] were measured.
Results: The descriptive statistics for females point to lower values of average morphologic factors of females training judo in comparison to control group. Contrasting: The average body mass, body fat percentage, as well as RI index for males practicing judo are higher comparing to the control group.
Conclusions: The spontaneous selection in judo practised prefers shorter females of lower body mass than in peers. Judo training has an impact on body mass gain in males in puberty. Biologically-conditioned body mass and height growth during puberty is to a great extent independent from stimuli used in judo training.
