Overweight and obesity as limitation factors of agility and strength development

The increase of prevalence levels of overweight and obesity among children worldwide is alarming since obesity related health risks are no longer only seen in adults. The aim of the current research was to investigate the effect of the overweight and obesity as limitation factors of agility and strength development among 125 seven- year-olds. By the international cut off points for BMI for overweight and obesity three groups of subjects were extracted: normal weight (78.4%), overweight (16%) and obese (5.6%). A total of 6 tests from the „Bruininks-Oseretsky Test of Motor Proficiency 2“ was extracted for the agility and strength assessment. Three independent samples t tests were calculated to investigate significant differences in agility and strength between the groups. In the motor area of speed and agility, as well as in the strength area, significant differences were found between the overweight and obese (p=0.04, p=0.05), as well as between the normal weight and obese group of subjects (p=0.01, p=0.02). These results point out to a fact that slightly increased BMI in children does not necessary impair their motor abilities performance. However, a serious BMI increase could affect children’s agility, speed and strength and prevent their further motor development.
