“…A ação de sacar é único momento do jogo de tênis que não apresenta interação direta com ações anteriores. Essa característica possibilita ao sacador um maior controle sobre a execução do movimento e sobre o resultado, uma vez que a pressão de tempo para a realização do golpe é menor 9 . Do ponto de vista da elaboração de jogadas, o sacador apresenta duas vantagens importantes sobre o devolvedor.…”

“…Para os segundo saque, os resultados deste estudo apontam tendências diferentes das relatadas na literatura [7][8][9][10] , observando-se: uma relação entre o percentual de pontos vencidos e a direção aberta, no lado do Iguais; e não sendo encontradas associação significativas entre as variáveis pontos vencidos e as diferentes direções, no lado das Vantagens. No estudo conduzido por Hurley 7 ,onde foram analisados 248 jogos (126 partidas masculinas e 122 femininas) do torneio de Wimbledon, a autora identificou que o segundo saque aberto, em geral, foi a opção utilizada com maior frequência para se vencer os pontos, quando comparado às demais direções.…”

O objetivo do estudo foi analisar a relação existente entre o saque e o desdobramento dos pontos de jogadores em torneios profissionais de tênis de porte intermediário. Para isso, foram analisadas in loco,1569 ações realizadas por 12 tenistas destros, do sexo masculino, em 11 jogos de eventos de nível Challenger da Associação de Tenistas Profissionais. Para análise dos dados foram empregados cálculos estatísticos descritivos e inferenciais (Qui-quadrado, Kruskal-Wallis e Mann-Whithney). Os resultados indicaram que os jogadores vencem significativamente mais pontos (p=0,000) quando sacam (64,9%), com 60,1% desses pontos sendo associados à efetividade do serviço. O primeiro saque apresentou maior associação com o percentual de pontos vencidos (X²53,956; p=0,000), e efetividade quanto à forma de finalização dos pontos (p=0,000). No que se refere à direção aplicada, observou-se uma maior incidência de saques abertos e fechados (p=0,002). Os serviços orientados para essas direções foram responsáveis por aproximadamente 70% do êxito dos sacadores. Conclui-se que a efetividade do saque exerceu um papel determinante na pontuação do jogo. Como implicações práticas sugere-se aos treinadores que atuam com esse nível de jogadores, uma atenção aos trabalhos de saque dentro das sessões de treino, especialmente do primeiro saque direcionado as extremidades da quadra.

“…This system builds upon the earlier Hawk-Eye [Internet 4] system developed in 1999, whose main goal was to track the ball so as to allow players to double check the umpire's decision whether a ball was in or out. However, some scientific research was performed using the Hawk-Eye system, such as the analysis of service shot trajectories [Kolbinger, Lames 2013].…”

This study focused on the application and accuracy of spatially marking tennis shots in a special computer interface based on the visual observation of video recorded tennis play. The interface program, graphically designed in the shape of a tennis court, is shown on a computer screen along with a video showing a series of balls being hit and landing on the court. The task of the observer was to mark on the interface the location where he/she felt the ball falls on the court. In effect, the interface functions as a coordinate system whereby tennis play (in this case balls falling on one side of the court) is catalogued into a series of coordinative points. These data are then converted into a spreadsheet allowing for statistical calculation and analysis. The results of the trial indicated that the accuracy of the designated points on the interface depended on the distance between where the ball fell and the nearest line delineating the court. Balls that landed less than 0.3 m from the nearest line featured a mean distance error of only 0.11 m. For the purpose of analysing game tactics, the interface was found to be an applicable tool in the collection of tennis match data.

“…Hawk-Eye uses up to ten high-speed (60Hz) calibrated cameras to continually track the location of a tennis ball during a match. The system was originally introduced to allow players to 'challenge' line calls made by match officials (Kolbinger & Lames, 2013), but its implementation has also benefitted those in coaching, research, broadcasting and digital media professions, as well as enhancing fan engagement . From a research perspective, Hawk-Eye has facilitated the collection of a wealth of performance data and, in turn, provided extensive opportunities for analysis (Reid et al, 2016).…”

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.
