Özet:

This study was done with the aim of comparing the service satisfaction statistics in matches according to the average length values of the liberals playing in high-level volleyball leagues. In the study 2017/2018 Turkey Volleyball season with the Sultans League and the Epheler League in 2019 CEV European Men and Women Championship, 28 men and 36 women liberon's match statistics have studied service welcoming performance. First of all, the average size of the male and female liberals was taken. Liberoons with a length below the average value of 187 cm in men and 170 cm in women are "six of the average" and Liberoons with a length above these average are "more than the average". All of the 22 week normal league and playoff or playout matches of the liberals playing in the Sultans League and Ephers League, while the statistics of the liberals playing in the CEV European Championship in the group, quarter-finals, semi-finals and final matches have been studied and total values have been compared. In comparison between groups of the same gender, the independent groups of the same gender were tested. The ratio between the positive (%) and efficiency (%) values in service meetings and the length levels of all liberals was assessed by the Pearson Correlation Score test. Although statistical analyses do not make a significant difference when compared to the two groups determined by length, the service satisfaction efficiency in men is 8% higher in the "over average" group. Furthermore, when all data were compared to gender in all liberals, only the percentage of performance parameter found a difference in favor of men (p=0,01). These findings suggest that the influential factor in service satisfaction efficiency is not the "boy length", but it can have a positive impact in terms of the advantage of the field covered. In subsequent studies, it may be recommended to evaluate the effects of age, concentration, experience, speed, muscle strength, flexibility, etc. on service satisfaction performance.

This research aims to compare the receiving service statistics in the matches according to the average height of the libero players playing in the top volleyball leagues. Receiving service performance statistics in the matches of the 28 men and 36 women libero players playing in Sultanlar League and Efeler League in the 2017/2018 Turkish Volleyball season, and in the 2019 CEV Men's and Women's Championship were examined in the study. Firstly, the average height of male and female libero players were calculated. Athletes with a height of below average value of 187 cm in males and 170 cm in females were named as "below average group", and athletes with a height above the average values were named as “above average group”. The 22-week regular league and playoff or play out matches of the liberoes playing in the League of Sultans and Efeler, and in the group, quarter-final, semi-final and final matches statistics of the libero players in the CEV European Championship were analyzed, and their total performance parameters were compared. Independent two-sample T-tests were used in comparisons between the genders and between the groups in genders. The relationship between the positive (%) and efficiency (%) values of all liberoes in receiving service and their height was evaluated with the Pearson Correlation Coefficient test. As a result of the statistical analysis, although there is no significant difference when the two groups determined according to their height are compared, the receiving service efficiency in males is 8% higher in the "above average" group. In addition, when all data were compared between genders, a difference in favor of men was found only in the efficiency% parameter (p = 0.01). With these results, it can be said that the effective factor in the receiving service efficiency is not “height” of the libero but can have a positive effect in terms of area coverage. In future studies, it may also be suggested to evaluate the effects of different factors age, concentration, experience, quickness, muscle strength, flexibility, etc. in the receiving service performance.
