The sampling of the study was composed of a total of 45 students with 25 in the test group (10 males and 15 females), and 20 in the control group (8 males and 12 females), attending the Petkim Latife Hanim Primary School in Izmir. Different sports activities (athletics, yoga, basketball, educational games and dancing) were implemented for the test group for a total of 32 class periods. The "General Self-sufficiency Scale", "Matson Evaluation of Social Skills with Youngsters (MESSY)" and the "Physical Fitness Tests" were implemented with the first test, final test method. The SPSS 15.0 program was used in the analysis of the data, the " Paired Samples T-Test" was used in the determination of the differences within the group, whereas, for the independent groups, the " Independent Samples T-Test" was used.

When the change within the test group was considered, it was observed that there was a positive statistically significant difference in the height, weight, flexibility, balance and fat percentages, whereas, it was observed that in the control group there was a positive statistically significant difference only in the height, weight and balance parameters (p<0.05).
