This study investigated the development of a profile of body composition and size among competitive swimmers. A cluster sampling technique was used to select a sample from Deccan Gymkhana. The sample specifically included swimmers from the Under-17 (n – 12) and Under-19 (n – 12) age groups to focus on a particular stage of development. Data Collection Tools – Anthropometric measurements - Arm Length, Leg Length, Arm Circumference, Leg Circumference. Conclusion - Across all measured anthropometric variables specifically arm length, leg length, arm circumference, and leg circumference there were no statistically significant differences between competitive swimmers in the Under-17 and Under-19 age groups.
