Efecto del diseño de los balones de voleibol sobre el rendimiento de la recepción del saque femenino de alto nivel = Volleyball ball design performance effects on service reception in high-level women

Resumen

Introduction: The two best-known ball manufacturing houses, MOLTEN and MIKASA, have recently designed several models of balls with different characteristics, used in official national and international competitions. Objective: Determine which ball design facilitates or hinders the serve reception. Methods: The sample consisted of 146 women's matches played by 3 teams participating in high-level competitions: Italian A1, The Word Cup, Volleyball Nations League, Champions League, Türkiye Kadınlar Voleyball 1: of which a total of 62 matches where they played with the Molten ball V5M5000; 84 games were played with Mikasa balls; 39 of them played with the MVA200, and 45 with the V200W ball. The variables recorded were: paneling type, surface type, reception coefficient and performance. Results: Significant differences were found with a moderate effect size in the reception quality depending on the balls used (χ2 (10, N=9498) = 222.8, p<0.001, Cramer's V = 0.108). Taking as Coefficient reference and Reception Performance data, it was observed that the MIKASA V200W seems to be the easiest ball to receive (CER=3.50; RR=6.37), while the ball that seems to be more difficult and that causes worse performance data is the MIKASA MVA200 (CER=3.26; RR=3.63). Conclusions: Therefore, based on the records obtained, we can affirm that the type of ball influences the quality of reception of high-level women's teams.
