Skills Importance across Ages for Men’s Volleyball
Sotirios, Drikos Ioannis, Ntzoufras
Volleyball is a competitive team sport whose main objective is to score the most points by grounding the ball to the opponents side of the court. The numbers of points a team scores is primarily based on the execution of the skills of the game. Due to the hierarchical structure of the game events follow stable patterns: serve outcome, pass–set–attack (complex 1) outcome, Serve–block–dig–set– counter attack (complex 2) outcome. The outcome consists of four possibilities: To win or to lose a point, continuation of the action with the ball on the team’s side or with the ball on the opponent’s side. In this paper we provide a method to calculate the importance of every skill on the outcome of the Volleyball game for youth, juniors and men teams. We base our analysis on Fellingham’s model for importance scores. We use data from the performance analysis of the winning team from the most recent world championships in all ages for male volleyball. In order to arrive at posterior distributions, we use a Markov chain transition matrix. To estimate the Markovian transition matrix, we assume a multinomial likelihood with a Dirichlet prior on the transition probabilities. The prior distribution of skills is formed by expert coaches’ opinion. Our main purpose is to examine if key skills are consistent across ages in male volleyball. (EN)
