Participation in Sport, Body Mass Index, and Motor Proficiency in 5 to 6 Year Old Children.


The purpose of this study was to examine the relationship between sports participation (SP) body mass index (BMI) and motor proficiency (MP) in five to six year old children. The sample consisted of 144 children (71 boys and 73 girls) attending public kindergarten in Attici prefecture (Greece) aged 60 to 72 months (Mean=67.47months, SD=3.21). Anthropometric measures of height and weight were obtained for calculation of BMI values. For the assessment of MP, the Bruininks-Oseretsky test of motor proficiency-second edition (BOT-2) was used and parents were questioned about sport participation of the children. For the statistic analysis of the data, a multivariate analysis of variance (MANOVA) and nonparametric correlation (Spearman rho) were used. Statistically significant main effect for gender (F1.132=5.64, p<.05) was found for BOT-2 Total Point Score (TPS), with girls scoring higher than boys (MD=6.44, p<.05). Sport participation was significantly correlated with BOT-2 descriptive category (r =.191, p<.05) but not with BMI types. Consequently, even though the results revealed a tendency for sports participation to affect motor performance positively, in order for SP to affect BMI determined obesity it might need to be in conjunction with increasing regular physical activity in and out of school.

Relationship between BMI, physical activity and TV-watching in preschool children.


The aim of this study is to identify the relationship between BMI, physical activity, and hours of watching TV in preschool aged children. The sample consisted of 102 children (49 boys and 53 girls) aged 48 to 79 months (Mean=60.67, S.D.=7.07). Physical activity was measured using an OMRON walking style II pedometer, while hours of TV watching and occupation with “digital” games were recorded using a parent questionnaire. Differences between groups were assessed using one way analysis of variance (ANOVA). From the results was not found any statistically significant effect of BMI in number of steps/week (F =.411, p=.672), in number of covered km/week (F=.411, p=.673) and in hours of TV watching/day (F=.004, p=.996). However, statistically significant difference was found in the level of physical activity between children that watched less than 1h TV per day, (number of steps/week: Mean=61426.75, SD=10766.28) and total km/week: Mean=24.54, SD=4.31) and children that watched above 5h TV per day, (number of steps/week: Mean=37753.25, SD= 2975.89 and km/week: Mean=15.07, SD=1.18). Consequently, ΒMI is not a perfect predictor for preschool aged children to show any differentiations in relation to older children. However a negative association is possible to exist between physical activity and hours of TV watching at a sensitive time period.
