Objective: The purposes of this study were to examine the association between motor competence (MC) and body mass index (BMI) in children aged 10-13 and to determine gender-related differences in motor competence. Material and Methods: Participants were male (n=59) and female (n=44) children between the ages of 10 and 13 (12.1±1.2 years). Body height and weight were measured and BMI was calculated as dividing the body weight by the square of the body height. 'Körperkoordinationstest für Kinder (KTK)' was used to assess the MC of the participants. The KTK includes four subtests; walking backward, hopping on one leg, jumping sideways, and moving sideways. The raw scores for each subset were converted to the age- and genderspecific motor quotient. The sum of four items was used to calculate the total KTK motor quotient scores. Finally, the total KTK motor quotient scores were utilized to classify the MC levels of children. Results: The results of the study indicated that 33% of participants performed below the normal level in motor competence. Further, there were no significant (p>0.05) differences between boys and girls in terms of anthropometric characteristics and the total KTK motor quotient scores. Regardless of gender, results revealed that MC was significantly (p=0.001) and negatively associated with BMI. Conclusion: Based on these findings, it may be stated that increasing BMI has a negative effect on MC in children aged 10-13.

Amaç: Bu araştırmanın amacı, 10-13 yaş arası çocuklarda motor yeterlik ve beden kitle indeksi (BKİ) arasındaki ilişkinin incelenmesi ve cinsiyete bağlı motor yeterlik farklılıklarının belirlenmesidir. Gereç ve Yöntemler: Araştırma grubunu, 10-13 yaşları arasındaki (12,1±1,2 yıl) erkek (n=59) ve kız (n=44) çocuklar oluşturmuştur. Araştırma grubunun boy uzunluğu ve vücut ağırlığı ölçülmüş ve vücut ağırlığının boy uzunluğunun karesine bölünmesi ile BKİ hesaplanmıştır. Motor yeterlik seviyelerinin belirlenmesinde 'Körperkoordinationstest für Kinder (KTK)' testi kullanılmıştır. KTK 4 alt test içermektedir; geriye doğru yürüme, tek ayak atlama, yana sıçrama ve yana hareket etme. Alt testlerden elde edilen ham skorlar, yaşa ve cinsiyete özel motor katsayılarına dönüştürüldü. Dört alt testin skorlarının toplanması ile KTK toplam motor katsayı değeri hesaplandı. Son olarak, katılımcıların motor yeterlik seviyelerini sınıflandırmak için toplam KTK motor katsayı skorları kullanıldı. Bulgular: Araştırma sonuçları, katılımcıların %33'ünün normal seviyenin altında motor yeterlik performansı sergilediklerini göstermiştir. Ayrıca antropometrik özellikler ve toplam KTK motor katsayı skorlarında cinsiyete göre istatistiksel olarak anlamlı bir farklılık olmadığı (p>0,05) anlaşılmıştır. Sonuçlar, cinsiyetten bağımsız olarak, motor yeterlik seviyesi ile BKİ arasında istatistiksel olarak anlamlı ve negatif yönde bir ilişki olduğunu (p=0,001) göstermiştir. Sonuç: Bu bulgulara göre 10-13 yaş arası çocuklarda artan BKİ'nin, motor yeterlik üzerinde olumsuz etkisi olduğu düşünülebilir.
