Abstract

Quality of exercises performed by 16-year-old gymnast-girls of high qualification using 106 various anthropometric profiles has been stated experimentally. The data obtained have been subjected to statistic, correlative and factor analysis. As demonstrates analysis of 190 correlation coefficients between the anthropometric parameters (AP) of the gymnast-girls, 72 coefficients have meanings of strong interconnections, 104 - of middle and 14 - of poor interconnections. The direction of the interconnections is positive. Factorization of matrix of the gymnast-girls AP makes it possible to distinguish three factors; their summational contribution into total variance sample makes 79.1. Exercises of a certain technical structure, at other similar conditions, are performed by the gymnast-girls possessing a peculiar anthropometric profile. Besides, the gymmnast-girls, demonstrating at various levels similar technical results, are similar in their anthropometric profile. For example, when performing the same qualified exercise, in the first group are included the gymnast-girls with the mark 9.93 from 10. AP of these gymnast-girls are: body mass 43 kg, body length 155 cm, length of their arms up to the styloid radial point 50 cm, length of the legs up to the lower tibial point 75 cm. With increase of the four AP mentioned, a tendency to a decrease in the quality of the exercise performance is noted. Comparison of the gymnast-girls AP with the AP earlier established makes it possible, to some extent to prognosticate sporting improvement. Verf.-Referat
