Abstract:

Position determination of game analysts is often performed by subjective visual estimation. The aim of this study was to evaluate human position estimations for setting actions in beach volleyball. Subjects were asked to assign the athlete's position to one of five cells representing the court. Position estimations from seven beach volleyball experts and seven non-experts were compared with results of video metrology also presented in this paper. A mean error-quote of 41% indicates that the perception of humans assessing athlete's position is very inaccurate. While beach volleyball experience did not influence the ability for position estimation, the accuracy was dependent on the distance from the camera. The obtained results should be taken into account by coaches and scientist, who deduct their strategy on such analyses. If it is not possible to get exact position information with technical systems, we recommend close-up views and adequate cell size to improve validity of results.
