الملخص EN

The study aimed to identify the effectiveness of receiving and defensive skills in volleyball and their relationship to the ranking of the first-place teams participating in the Tokyo Olympics 2021.

the descriptive approach was used on a sample of (48) players representing the teams that won the first four places in the tournament, and they were chosen in an intentional way.

data was collected by the FIVB match analysis committee.

the data were analyzed using arithmetic averages, frequency, percentages, Kruskal-Wallis test, and Mann-Whitney test.

the results indicated that there were no statistically significant differences at the significance level (α≤0.05) between the level of receiving serves & defensive skills on the first-place teams’ ranking.

and that the level of effectiveness of reception was high and close to all first-place teams.

defending had a positive impact on the success of the teams attack.

the study recommended paying attention to allocating more time to train on receiving serve and defensive skills for all players, and to analyze all offensive and defensive skills together to link volleyball skills and their influence on each other.
