Selection is the uninterrupted process of screening, selection and sorting of young people according to well-defined criteria and their guidance towards the practice of a certain branch or sporting evidence in which they can best value their qualities to achieve performance. The selection process is a complex and continuous system of appreciation of the full level of training of the fighters and of the propulsion of those with the potential to progress on the upward path of training in order to achieve more and more valuable performances. The selection is closely related to the training process (through its objectives and content). Selection as a methodical process should not be reduced to the initial selection. In wrestling, a factor of most importance is the proper selection of the most endowed among the youngsters for practicing this type of sport. The selection is all the more advantageous as the final objectives of the training are better known. It is vital for the coaches to know the development trends of the wrestlingin the world, to know the level of the technique and tactics of fighting, and also the psycho-motors of the bestperforming athletes. In view of the above, selection for practicing wrestling is an elaborate process that seeks to detect athletes with innate availability to guide them to combat wards. Based on these considerations, it is our job to find out if there are significant differences between the Olympic champion fighters in terms of: the age of selection, the age of achieving the great performance, and the period of practice necessary to obtain it. Conclusions. The average age of selection in battles is currently around the age of 7-9 years.The period of accumulation required (the period of practice required to achieve top performances in wrestling), according to the data obtained from the present investigation, is approximately 11-12 years. As for the average age that favours the achievement of the great performance in battles, it is 25 and 27 years, the value obtained in this respect being statistically representative. At the same time, the first medals will be achieved around the age of 20.
