Influence of cognitive performance and swimming capacities on selection of youth water polo players to national team.

BACKGROUND

Water-polo is an official competitive olympic sport with high energy and technical-tactical demands. The aim of this study was to evaluate the influence of cognitive performance and specific swimming capacities on the selection of youth water polo players to the national water polo team.

METHODS

There were 83 youth water polo players (mean age 13.61±0.67 years) who attended the Croatian Water Polo Foundation training camps included in this cross-sectional study. Testing included anthropometric measurements, specific swimming capacities and cognitive performance (Stroop test).

RESULTS

Among 83 youth water polo players included in this study there were 13 goalkeepers, 13 center-defenders, 13 centers, 31 perimeter players and 13 wings. Selected players (N.=40) performed faster in OffTime (selected 62.99±10.21 s vs. non-selected 69.98±8.93 s, P=0.002) and OnTime (selected 75.61±15.85 s vs. non-selected 86.01±15.40 s, P=0.004) of the Stroop test than non-selected players (N.=43). Logistic regression analysis showed significant association between selection of youth water polo players to the national team and swimming results in 400 m crawl and 100 m crawl, as well as OffTime, OnTime and OnTime minus OffTime on the Stroop test.

CONCLUSIONS

The results of this study showed that psychomotor ability, inhibition, motor speed and cognitive flexibility were found to be the most important predictors for the selection of youth water polo players to the national water polo team. Furthermore, selected water polo players demonstrated better psychomotor abilities, inhibition, and motor speed, as well as better results in all specific swimming tests in comparison to non-selected players.
