Sex Differences in Discriminative Power of Volleyball Game-Related Statistics

Abstract

To identify sex differences in volleyball game-related statistics, the game-related statistics of several World Championships in 2007 ( N = 132) were analyzed using the software VIS from the International Volleyball Federation. Discriminant analysis was used to identify the game-related statistics which better discriminated performances by sex. Analysis yielded an emphasis on fault serves ( SC = –.40), shot spikes ( SC = .40), and reception digs ( SC = .31). Specific robust numbers represent that considerable variability was evident in the game-related statistics profile, as men's volleyball games were better associated with terminal actions (errors of service), and women's volleyball games were characterized by continuous actions (in defense and attack). These differences may be related to the anthropometric and physiological differences between women and men and their influence on performance profiles.
