A test battery covering eight anthropological variables and one motor test was applied on the sample of 164 female subjects included in the program of development gymnastics and 180 9-11 year old girls from the region of major cities of Vojvodina, who were not engaged in physical activities. Subject of analysis were anthropometrical measures for evaluation of morphological characteristics and a 'bent-elbows-hang test' for assessment of relative static strength of arms. The purpose of this analysis was to find out whether there were any differences between relations of the analyzed morphological characteristics and relative static strength of arms in the two groups of girls at different level of physical engagement. These relations were analyzed by linear regression analysis. Results of this analysis showed that there were no significant differences between morphological characteristics and relative strength of arms in the two groups of girls at multivariate level. Namely, even five out of eight anthropometrical variables took statistically significant effect on performance efficiency of the criterion test in the girls engaged in the program of development gymnastics, whereas in the other group the only significant but negative effect was that of the variable of subcutaneous fat of upper arm. According to the results it can be concluded that it is not possible to predict relative strength status of arms based on morphological characteristics in girls doing no physical activities, whereas in girls engaged in the program of development gymnastics, it is possible to a solid level. .
