Int J Exerc Sci 1(1): 22-29, 2008. The purpose of this study was to determine if upper body segment length or mass contributes to vertical jump (VJ) displacement. Seventeen men (n=9) and women (n=8) who were active recreationally participated in this investigation. Subjects performed VJ for maximal displacement, and skeletal length measurements of the humerus (acromion following the lateral lip to the greater tuberosity), ulna (olecranon to the ulnar styloid process), and hand (lunate to distal end of third phalanx) were obtained by palpation of boney landmarks and a standard tape measure. Pearson Product Moment Correlation Coefficients were used to compare the data with statistical significance accepted at the p=0.05 level. Length of the ulna was the only upper body limb measurement that was significantly correlated with the vertical jump (P = 0.04). As the regression equation to predict VJ from ulnar length was not significant, it appears that neither intrinsic upper arm skeletal length nor arm segment mass is a strong predictor of VJ displacement.
