AB [EN] Objective The aims of this study were to analyze the shoulder functional profile of young male andfemale tennis players and to establish the relationship among physical variables and servespeed.Methods A total of 128 Spanish tennis players (Under-13 (n = 32/32 males/females) and Under-15(n = 36/28 males/females), were tested during National training camps. Tests included passiveshoulder range of motion (ROM) for both internal (IR) and external rotation (ER) andisometric strength (i.e., IR and ER) of the dominant/non-dominant shoulders, medicine ballthrows (MBT), and serve speed. Age and sex pairwise comparisons were carried using theHedges’ g index (dg).Results Results showed age and sex effects on serve speed and all MBT, with males showinggreater changes (1.51<=dg<=1.98) with age than females (0.92<=dg<=1.35; p<0.05). U15males showed higher (p<0.05) absolute shoulder IR and ER strength than U13, with onlysignificant differences between males and females in the U15. Regarding ROM, U15 malesshowed a decreased IR ROM compared to U13 (dg = -0.84; p<0.05) and higher significantIR bilateral deficit (dg = 0.51; p<0.05). The distances obtained in the different MBT were thevariables more correlated to serve speed.Conclusion The present results suggest that shoulder strength, medicine ball throws and serve speedincreased along with age in young elite tennis players of both sexes. However, a decreased
