Based on the result that have been conducted, the arm muscle strenght is 26.6%, and balance is 29,7% to the upper passing ability. The precentage of correlation between the value and upper passing ability is influenced by th score of arm muscle strenght, hand squeeze muscle strenght, leg muscle stregnht and the balance; it’s about 14%. whereas for 86%% is influnced by other factor which is not included in this research.
