Motor development, Bmi in children 8-10 years old.

The aim of the study was tho investigate the relationship between BMI and motor development; it tries to show the gender differences in different BMI in the body movements in the horizontal plane.Participants. 400 subjects (Apulian Region) who are 8-10 years old have been examined: 209 male (71 normal-weigth, 69 over-weigth, 69 obese); 191 female (72 normal-weigth, 60 over-weigth, 59 obese) in one project in collaboration between Course of Degree in Sciences of the Motor and Sporting activities and School Sport Puglia.Methods. The BMI èas been calculated after weight and height, according to Cole (Cole et al.,2000) ; the sample of 400 children has been measured by four motor tests:standing long jump, 20m sprint; 20m slalom basket; ball frontal throw (Falk et al., 2001). Results. Significant differences emerged by sex and group: in the first three motor tests, where the movements of the body involved are in the horizontal plane, Normal-weight Male subjects are faster, stronger and more coordinated than over-weight, obese (p <0,05) and female subjects(p <0,01). In the test of basketball frontal throw, where the movements of the body don’t include movements in the horizontal plane, the obese Male show greater performances than Over and Normal-weight (p <0,05).Conclusion. In this study we can Conclude that the motor development is correlated to the gender and the BMI. The condition of overweight and obesity affect the motor development and learning. Overweight and obese children who have a lower motor development risk in adulthood showing ever lower and lower levels of motor development with increasing health risks.
