Abstract: Anthropometric characteristics are important indicators of physical fitness and sports performance. Among these variables, upper arm muscle circumference reflects muscular development and strength of the upper limbs, which are essential for many sports activities. The purpose of the present study was to compare upper arm muscle circumference between tribal and non-tribal sportsmen of Goa with reference to age groups. A total of 100 male sportsmen were selected as subjects for the study, including 50 tribal and 50 non-tribal players from different sports disciplines in Goa. The subjects were further categorized into two age groups, namely 21–25 years and 26–30 years. Upper arm muscle circumference was measured using a standard measuring tape following accepted anthropometric procedures. The collected data were analyzed using mean, standard deviation, and independent t-test. The results indicated that non-tribal sportsmen showed slightly higher mean values of upper arm muscle circumference compared to tribal sportsmen in both age groups; however, the differences were not statistically significant at the 0.05 level of significance. The findings suggest that regular participation in sports activities contributes to similar muscular development among tribal and non-tribal athletes regardless of age group.
