摘要：The aim of our study was to determine somatic and motor differences between the mostefficient and the least efficient players in an attack in outside players positions (outside spiker and opposite) and middle players (blockers) at Volleyball Women'sEuropean Championship 2019. We obtained the researched data from the available CEV database. When determining the most efficient and least efficient players we used the order of the best, resp. the weakest ten players in a given player position. Specifically, we compared their body height, weight, jump reach from approach and in standing jump reach. To find the differences we used the nonparametric Mann-Whitney U-test and for the Effect size r according to Mangiafico (2016). We set the level of statistical significance at p < 0,05. When comparing the effectiveness of the most successful and least successful outside players, we found a significant difference in body height (z = 2,721; p = 0,007), body weight (z = 2,419; p = 0,016) and reach in the jump from approach (z = 2,306; p = 0,021). In the group of middle players in terms of the effectiveness of their attack we found a significant difference in body height (z = 2,117; p = 0,034) and standing jump reach (z = 2,948; p = 0,003). The body height of the players shows as a common parameter of higher effectiveness of the attack in both studied player positions. Based on effect size (r = 0,16 – 0,29) we can indirectly infer a small effect of the given parameters on a success of an attack. We can use the results when selecting players for individual player positions in women's top volleyball and in the search for the causes of the players' success in the implementation of the attack.
