The goal of the research was to establish hierarchy of water polo players classified by their position who are Adriatic league juniors of which many participate in senior games. This league is one of the strongest in the world. This paper could be used to prove some rules important for modeling, selection and therefore using top notch water polo training for this population (possibly reducing number of injuries during more adequate and useful training sessions) This can be done by revealing hierarchy of water polo players motor skills and getting those facts partly responsible for success , together with coordinated work of relevant individuals (all water polo coaches, fitness coaches, scientists in the field etc). Testing was done on Adriatic league junior water polo players. 15 players per club from seven clubs were tested , all together 104 water polo players. Testing was carried out in pools and gyms in Dubrovnik (W.C “Jug”), Split (W.C. “Mornar”), Rijeka ( W.C. “Primorje”), Sibenik (W.C. „Sibenik“), Zagreb (W.C. „Medvescak“ and „Mladost“), Herceg Novi (W.C “Jadran”). The above mentioned players are registered in their home clubs and therefore eligible to compete in the league. Of all the tested players only the result of those players that are healthy with no morphological, psychological or other aberrations were taken into the account. Results clearly indicate differences between different positions (outside wingers, centers, defense and goalies) established after testing candidates with 10 motor skills variables specific for water polo players.
