The motoric functions of children according to maturity coefficient

Abstract

This study compares performance levels among early, average, and late maturing boys and girls. So, the purpose of this study is to compare the age and gender related differences in motoric functions of according to chronological and biological age. Material and Methods: Research groups consist of ngirl=362 nboy=331 with different academy of junior sports hall changing their age from 7 to 11 years, child players were instructed to give their maximal efforts during all tests. The research groups’ training age (mean=1.77±0.28 year) was attained. All child trained three days a week (1-1.5 h of training day). Chronological age was calculated by subtracting the participant's date of birth from the observation date transformed into decimal age (in years) and maturity offsets were calculated. The research groups were measured for mass, standing height and sitting height. Leg length was calculated by subtracting the participant's sitting height from their standing height. Body mass was measured using a strain gauge scale and body mass index was calculated. For the physical and motoric attributes, stretching, high jump, long jump, hand grip, medicine ball throw, velocity and agility test were applied. Results: As a result, chronological age has an important influence on more complex tasks in which coordination, the performance superiority was appeared. When examining the performance parameters according to age change in terms of gender, the boys at every age except 10 years, are superior in velocity, hand grip, medicine ball, agility and long jump parameter adds to these superiorities after 9 years. From the differences obtained in terms of performace parameters, it is seen that who is at the level of early maturity is superior. Conclusion: In this context, as a result of the research, it can be said that the maturity coefficient has positive effects in performance at different ages. © 2015 by Türkiye Klinikleri.
