Methods: Total 21 trained male tennis players 9-11 years (mean age10.46 years) were participated in this study and their body size, body composition and body type were determined by ISAK recommended method. Players were classified according to their somatotypes into dominant endomorph, mesomorph and ectomorph. Some performance oriented anthropometric measurements were also measured by using standard methods.

Results: One way ANOVA followed by Scheffe’s tests (p<0.05) was done among the three dominant somatotypes. Hand span, hand length, hand width, cubit length, and wrist circumference were found to be significantly (p<0.05) differ among the three dominant groups.

Conclusion: This finding states that trained players have their own body types. Different performance oriented upper arm measurements were also differ among these groups. It will be more effective and appropriate for the players when they classified according to their body types and designing of sport equipments on the basis of their somatotypes.
