„Z”-scores of anthropometric and motor parameters of girls in aerobic gymnastics

This study presents the evaluation of chosen anthropometric and motor parameters in group of female junior competitors throughout the course of 2-year preparation of aerobic gymnastics by means of Z-scores. The observed group consisted of 12 girls (average age at the beginning of observance 14.08 ± 1.19 years). Evaluation of anthropometric (body height, body weight, body mass index, percentage of body fat, acting body weight) and motor parameters (sit-ups in 30 seconds and 60 seconds, pull-ups to bar, modified push-ups, standing long jump, backwards tandem walking, shuttle run 4×10 m, Jacík’s test) was carried out in standard conditions in nine girls at 3-month intervals. It has been confirmed that female probands with higher Z-score of motor parameters together with lower Z-score of anthropometric parameters achieved higher sport performance during the 2-year observance at competitions, with an exception of one such proband.
