Abstract

 Abstract
Background:
Talent identification reduces stint to achieve better sports performances by elite athletes. The purpose of this study was the determination and prioritizationof anthropometric, biomechanical and functional characteristics of the elite boys for talent identification and predicting the performance in 100m Backstroke swimming.
Methods:
The research method is semi-experimental, which is applied based on the object and aim, and it is descriptive according to the method and strategy. The subjects were 30 elite young swimmers, which had won top rank in their provinces and came to the national championships, then they had completed the individual questionnaire and satisfaction questionnaire.The anthropometric, biomechanical and functional parameters were measured by Rydkov questionnaires. Data were analyzed using mean±SD and friedman tests and using SPSS software version 22.
Results:
The most important anthropometric parameters were hand length (13.00 cm), forearm length (23.50 cm) and foot length (18.20 cm); the most important biomechanical parameters were elbow hyperextension (3.93 degree), ankle plantar flexion (6.97 degree) and trunk hyperextension (40.87 degree); and the most important functional parameters were action and reaction velocity (20.74 cm), flexibility (26.99 cm) and high jump (29.30 cm) in 100m Backstroke swimming of the elite 11-12 year-old boys.
Conclusion:
The results of this study for talent identification and predicting the performance of the elite 11-12 year-old boys in 100m Backstroke swimming, can be considered by authorities, practitioners and coaches.
