Factorial structure of sports activities for divers of different sexes at the age of 9-13 years.

Abstract

A factor analysis of the sport activities of aquatic divers between 9 and 15 years of age, carried out over three years with boys (104) and girls (102) determined that the sports activities of boys and girls aged 9 to 11 are very similar. The factors of nystagmus reactions to rotational loads in 10-year-old children are common to all groups, but differ in factorial structure and contribution to total dispersion. In the group of children, the factors of physical development and sports technical preparation are still valid throughout the study period, while girls aged 12 to 13 experience changes in the importance of the factors identified and the integration of factor indicators that hinder their interpretation.
