Abstract
The comparative analysis of results of a large number of investigations was done. The investigations dealt with the indicators concerning the innate special traits and the factors in speed movements in twins and families. The conclusion were:
- different speed traits have an unequal genetic conditioning and, therefore, their changeability is in relation to external factors;
- there are clear differences in the genetic condition of speed traits for arm and leg movements, as well as for the eft vs. right extremities;
- the level of genetic conditioning of speed motoric indicate change through age. The highest level of innateness is achieved in maturity;
- there are clear sex differences in the genetic determination of the components concerning traits for speed movement;
- phenotype changeability and level of similarity with the parents varies in motorics indicators in different stages of child ontogenesis.
The significant specific genotype level in determination of speed traits and their relatively limited evident changeability under the influence of sports training determine their mutual correlation of biological laws of development and the potential for training of is trait in motorics.
