The sample of 286 girls included in program of development gymnastic and 581 girls which are not included in any sport age 7-11 from a territory of largest cities of Vojvodina, were tested by 8 motor tests. The aim of research was to compare motor abilities of girls included in program of development gymnastic to those who are not included in any sport, and to analyze how much the gymnastic sports are efficient in transformation of treated abilities in female population during a highly sensitive stage of biological development. Based on multivariant analysis of variance (MANOVA), statistically significant differences were determined in system of motor abilities. Analyzing the individual motor tests, based on the univariant analysis of variance (ANOVA), statistically significant differences even on level q=.00 were determined in almost all motor tests in terms of better results at girls included in program of development gymnastic. It can be said that gymnastic contents are efficient instrument of positive influence on motor abilities of girls aged 7-11, and that they are recommended for implementation in physical education, in schools and elsewhere. This is especially important in view of great sensibility of biological development in referred age.
