indent Abstract
On sample of 757 pupils, 379 boys and 378 girls, school age from 3rd to 6th class, nutrition status, acoording BMI, and motor status were analyzed by using 8 variables (3 for valuation of morphological and 5 for evaluation of motor abilities status). In the overall sample, 66.3% established a normal nutritional status 18.4% was overweight, 15.3% were obese. Obesity is the most vulnerable children in third grade (21.8%), and overweight in fourth (20.1%) and fi fth (20.9%) grade. The results indicate a statistically significant difference between the third and sixth grades, and no statistically significant differences in the frequency of overweight and obesity in all grades, or in relation to sex. Overweight has a negative correlation with explosive leg strength and muscle strength of arms and shoulders, while obesity has a negative correlation with the strength of muscles of arms and shoulders, running speed, strength of trunk muscle and explosive leg strength. Significant statistical relation was lacking in flexibility. The results show a statistically significant difference in the speed of running, muscle strength of arms and shoulders, trunk muscle strength and explosive leg strength between the overweight and obese pupils. A significant difference was not observed in the test to assess the value of flexibility. Generally, children who are overweight and obese have significantly reduced motor skills compared to normal children too soon, especially with regard to the manifestation of strength and speed.
