Separating winning and losing teams in sitting volleyball: the role of skills and differences across gender.
International Journal of Performance Analysis in Sport. Routledge.
AbstractSitting volleyball (SV) is a dynamic with short actions sport in the paralympic programme. The purpose of the study was to identify the volleyball skills that best discriminate between winning and losing an SV set, for both the genders. The data were collected from all sets played (N = 224) on the 2019 European men and women SV Championship. Cluster analysis established three types of sets according to the final score difference: 2–4 points (balanced), 5–11 points (semi-balanced) and over 11 points (unbalanced). Three-way MANOVAs were conducted to analyse gender, type of set and type of result differences for selected performance indicators. The analyses revealed significant multivariate differences across gender (p <.001), types of set (p =.014) and result (p <.001) and significant interaction effect of result with gender (p =.025) and type of set (p <.001). A follow-up discriminant analysis showed that setting and attacking were the most important skills for all sets. The results showed that in SV the attack is the most important factor, which determines winners and losers, even in balanced sets. In SV, the importance of skills across gender was similar to volleyball, while there were differences in the structure of the game compared to the sequential order of skills in volleyball.

Predictive factors of the setting performance and distribution per game complex in junior female volleyball.
Motricidade.
WebsiteAbstractThe present study aimed to analyse the associations between spatiotemporal characteristics of the setting and the origin of the ball in terms of the game complexes for junior female volleyball teams. Multinomial logistic regression and multiple correspondence analysis were applied to analyse 3.675 setting actions (Complex I = 1.593, Complex II = 2.082) in the final phase of the Greek Junior Championship. Results showed that the origin of the ball from the left lane of the court eases the setter for an accurate setting during CI while passing from the right lane incommodes the setter during CII. Regarding setting zone, for accurate setting, odds are increased by 3.2 for zone 4 during CI while decreased by 23.8 for zone 3 during CII. The junior setters' distribution of setting is predictable and creates favourable conditions for the opponent to deal with it. The improvement of junior female setters' ability to follow the team's offensive tactic regardless of the ball's origin, to manipulate passes received from the right lane of the court during CII and the acceleration of setting tempo for the wing hitters could be training goals for coaches.
