Background and Aim: Talent identification paves the way for identifying of success factors for reaching the summit of pride in all of sports, especially swimming and reduces stint to achieve better sports performances by elite athletes. The purpose of this study was the evaluation of the anthropometric, biomechanical and physical fitness and functional characteristics for talent identification and predicting the performance of the elite boys in 50m crawl swimming. Materials and Methods: 39 elite young swimmers, age 11-12 years, which ranks top in the championship and earned his province had been entered in national competitions, completed the letter of satisfaction questionnaires. The anthropometrical, biomechanical and physical fitness parameters were measured by Rydkov questionnaires. Data were analyzed using mean±SD and fried man test. Results: There is significant difference between the mean rank of length of limbs, angle of joints and functional-physical characteristics (p<0.05).The most important anthropometrical parameters were hand length (17.82 cm), forearm length (25.89 cm) and foot length (16.39 cm); the most important biomechanical parameters were elbow hyperextension (3.72 degree), ankle plantar flexion (6.69 degree) and neck extension (40.79 degree); and the most important physical fitness and functional parameters were action and reaction velocity (21.26 cm), flexibility (27.02 cm) and jump height (31.07 cm) for talent identification of the elite 11-12 year-old boys in 50mcrawlswimming. There is not a significant difference between the mean rank of fat content in three areas of supraspinatus, subscapularis and triceps. Also, the difference between the mean rank of left hand power and right hand power is not significant. Conclusion: The most important anthropometrical parameters were hand length, forearm length and foot length; the most important biomechanical parameters were elbow hyperextension, ankle plantar flexion and neck extension; and the most important physical fitness and functional parameters were action and reaction velocity, flexibility and jump height for talent identification and recognize of adolescent boys in 50m crawl swimming.
