Synchronized or artistic swimming is a complex sport consisting of elements of swimming, sports, and rhythmic gymnastics, modern dance, and ballet. Competitions are held in the disciplines team, combined routine, duet, solo, mixed duet, highlight routine and in technical routines that are for younger age categories, technical elements. Synchro swimmers are individually evaluated by judges in technical elements consisting of static and dynamic movements and most often contain a vertical position. Since it is not defined which motor skills and how much they affect the performance of individual positions and transitions this study aimed to determine whether balance, as a motor ability, affects the performance of vertical position in the water. The study was conducted on 26 synchro swimmers of different ages from the synchronized swimming club "Dolfina". Synchro swimmers were measured on static and dynamic balance on the Biodex device and were compared with three different elements in the water containing vertical positions. The correlation of the tests of balance "in dry" and vertical position was not achieved. However, due to a small sample, a large age range in subjects and the level of technical capacity, the correlation of balance with these elements cannot be excluded. It would be advisable to repeat the test in an older population and on a larger more homogeneous sample.
