Relations between Some Anthropometric Characteristics and Fundamental Movement Skills in Eight Year Old Children / Povezanost morfološke građe i biotičkih motoričkih znanja u osmogodišnje djece

Abstract

Abstract
This study was set to determine the relationship between Body mass index (BMI), percentage of body fat (BF) and fundamental movement skills of eight-year-old children. Seventy-three (36 boys, 37 girls) second grade children were included in the testing. Weight, height, triceps and calf skinfolds were measured for BMI and BF assessment. Two different approach fundamental movement skills tests were administered: "Test of Gross Motor Development-2" (TGMD-2) and fundamental movement skills test (FMS-POLYGON). The correlation between the BMI and the results in two administered tests proved not to be statistically significant. However, significant correlations were found between BF and total TGMD-2 score (r=-0.42; p=0.011) and the total FMS-POLYGON score (r=0.45; p=0.05) only among girls. The most commonly used test for body composition assessment in children - BMI - proved not to be precise enough in relations with FMS. Significant correlation between BMI and fundamental movement skills are expected only in targeted (homogeneous) group of subjects.
Key words: adipose tissue, body mass index, motor skills, obesity, TGMD-2.

Sažetak
Istraživanje je provedeno s ciljem utvrđivanja povezanosti između indeksa tjelesne mase (BMI), postotka masnog tkiva (BF) i biotičkih motoričkih znanja (BMZ) u dječaka (N=36) i djevojčica (N=37) prosječne dobi od 8,09 ± 0,25 godina. Kako bi se utvrdila razina usvojenosti biotičkih motoričkih znanja, primijenjen je test za procjenu kvalitete izvedbe BMZ „Test of Gross Motor Development-Second Edition - TGMD-2" i test za procjenu kvantitete izvedbe BMZ „FMS-POLYGON". Rezultati korelacijske analize pokazali su kako ne postoji statistički značajna povezanost između BMI i BMZ. Značajna povezanost dobivena je između BF i BMZ (TGMD-2: r=-0.42; p=0.011; FMS-POLYGON: r=0.45; p=0.05) i to samo kod osmogodišnjih djevojčica. Shodno dobivenim rezultatima može se zaključiti kako BMI pruža ograničene informacije prilikom definiranja povezanosti između morfološke građe i BMZ u odnosu na BF.
