“…A fundamental aspect of the C-ICC is its potential to address the hierarchical scoring system in volleyball, as also in tennis. This is known as the Quasi-Simpson paradox (Lisi et al, 2019) whereby the team with the lowest score can still win the match. Hence, not all points have the same importance, and the context of each event can make it more or less crucial for winning the match (Croucher, 1986).…”

In this study, we proposed novel metrics for evaluating volleyball technical performance in relation to the action context. To assess each player’s relative participation, we also introduced relative contextual coefficients. We analyzed 20 games played by the world’s top eight teams during the 2019 FIVB Women’s Club World Championship, using Data Volley software and Python programming. We evaluated inter- and intra-observer reliability and used binomial logistic regression models to estimate each variable’s probability of having contributed to the team’s set win. We calculated estimated confidence intervals, standard errors, and Wald values; and we employed Akaike’s and Bayesian criteria to evaluate the model’s goodness of fit. We identified optimal cut-off points using receiver operating characteristic curves, and we found that the proposed contextual evaluation coefficients prevented overestimation of a player’s technical performance in uneven situations. We addressed the issue in which the winning team may be the one that scored the fewest points, and we were able to predict a team’s victory with confidence. The proposed coefficients made multiple technical and contextual aspects of the game easily accessible and comprehensible, offering significant beneficial implications for coaches and players.

“…In contrast, Stanimirovic and Hanrahan [ 78 ] found that positive trends in the scoreboard or “momentum” were associated with psychological effects that affect performance. Similarly, sports like tennis with Simpson’s paradox scoring system [ 19 ] have shown a positive effect as a result of winning the previous point [ 86 ].…”

“…Finally, the high-level category was considered to be significantly more important by the experts (10/10 high load category versus 7/10 category attenuated load). This may be due to players tending to decrease their performance when they feel there is little chance of them winning and thus trying to save energy to more effectively recover for the next set [ 19 ].…”

The main objective was to know the elite coaches’ opinions regarding the relevance, definition, and importance of volleyball contextual variables to measure individual performance in competition. After performing a literature review, an instrument to gather the opinion of the world’s elite volleyball coaches was elaborated by four volleyball specialists. The sample of experts consisted in 20 world’s elite volleyball coaches who met at least three experience years in first division or national teams. The instrument collected experts’ information on the contextual variables in relation to relevance, definition, and importance. Cronbach’s α and Aiken’s V coefficient were used to test the reliability and content validity of the contextual variables, respectively. To compare the importance of the contextual variables U de Mann-Whitney and Kruskal-Wallis tests were used. Results showed that opposition level, set period, score difference, results of the previous set, competitive load variables, high level, final periods ≥20, and high load categories were relevant (Aikens V > 0.70). In addition, high level, final period ≥20 and ≥+10, and high load categories were significantly more important (p < 0.05). We conclude that, according to the elite coaches, the contextual variables should not be analyzed separately. Future studies should consider contextual variables dynamically.

“…), and could therefore appear insignificant, but it is important to note that this is not the case. The outcome of a tennis match can be decided by tiny margins (O'Shannessy, 2017a); it is even possible to lose more points than an opponent in a match and still win, a phenomenon known as the Quasi-Simpson paradox (Lisi et al, 2019).…”

Important performance characteristics in elite grass court tennis: implications for practice

Notational analysis has become a valued discipline and well-established tool in many sports. Historically, however, notational analysis and its potential for enhancing competitive performance have not been optimised in tennis, with a lack of grass court tennis research and associated practical applications particularly apparent. Additionally, tennis coaches have shown resistance towards technological advancements and are often unsure how to exploit the performance data available to them. In this thesis, a new, user-friendly data analysis method (Percentage of matches in which the Winner Outscored the Loser, PWOL) is developed and validated, to encourage tennis coaches to engage with notational analysis. The method is applied to Wimbledon match-play data, to identify the important performance characteristics in men’s and women’s elite grass court tennis. Points won of 0-4 shot rally length (i.e. short points) is revealed as the most important, so this characteristic is explored further, revealing the critical importance of serving and returning strategies. Accordingly, players’ tactical serving and returning behaviours are examined using Hawk-Eye ball-tracking data, with results highlighting that players tend to use first serves to put opponents under positional pressure by aiming for lateral areas of the service box, while opting for safer second serve strategies, typically targeting more central areas. Male winning players were also able to use their serves and serve-returns to force opponents out of position more often than losing players, hitting a comparatively higher percentage of serves and serve-returns to lateral areas of the court. Alongside the novel data analysis method, this thesis advances knowledge around the important aspects of grass court tennis match-play and provides insight into how matches are won at Wimbledon. Designed to inform practice, the practical application facilitates coaches aiming to develop evidence-informed practices for players during the grass court season, ensuring their training is representative of match-play. Implications for performance analysts and high-performance centres are also explored, to promote a more interdisciplinary approach to player development.
