9-14 Yaş Kız Çocuklarında Motor Yeterlik ve Algılanan Yeterliğin Biyolojik Olgunlaşma Durumlarına Göre İncelenmesi

Abstract

This study aimed to examine motor competence and perceived competence concerning biological maturation, sports participation experience, body mass index (BMI), and chronological age in girls aged 9-14. A total of 909 girls (mean age=11.76, SD=1.66 years) participated in this study. Motor competence was assessed using the "The Körperkoordinationstest Für Kinder (KTK)", and perceived competence was evaluated using the "Perceived Motor Competence Questionnaire for Children" for ages 9-11 and the "Physical Self Inventory-VS for ages 12-14. Biological maturation was determined using the peak height velocity (PHV) formula by Mirwald. Multivariate analysis of variance (MANOVA) revealed a significant interaction effect between PHV status and biological maturation in motor competence (p<0.01). One-way analysis of variance (ANOVA) and pairwise comparisons indicated that early-maturing girls demonstrated lower motor competence (p<0.05). The interaction effect between PHV status and sports participation experience in motor competence was found to be significant (p<0.05), and it was observed that non-participants had lower motor competence compared to sports participants (p<0.05). At ages 9-11, it was observed that girls who matured later had lower scores in perceived object control (p<0.01). It was found that the perceived competence scores of non-sports girls aged 9-11 and 12-14 were lower than those of girls who played sports (p<0.01). According to the chi-square test, late-maturing girls perceived their competence as under-estimators, while early- maturing girls perceived it as over-estimators (p<0.05). BMI values were lower in the under-estimators profile, while chronological age was lower in the over- estimators profile compared to other perception profiles (p<0.05). In conclusion, the results indicate that biological maturation plays a role in motor competence in the 9-14 age group and perceived competence in the 9-11 age group. Furthermore, sports participation experience plays a role in both motor competence and perceived competence. It was observed that late-maturing and low BMI girls tend to be under- estimators while early-maturing and older girls tend to be over-estimators.
