Differences in competition statistics between winners and losers in male and female tennis players in Olympic Games

The aim of this study was to examine differences in the performance indicators between winners and losers in male and female high-level tennis players. A total of 128 tennis singles matches played on grass court surface at the London 2012 Olympic Games were analyzed. Data were collected from the official website of the Olympics and the following groups of variables were analyzed: serve variables (n= 7), serve return variables (n= 3) and game-related variables (n= 5). The results showed that winners had greater (p< 0.05) values of second serve (%), aces, first and second serve points won (%), points won on first and second serve return (%), break points played and break points won (%). Furthermore, they get more winners with both groundstrokes and net points won (%) than losers in both sexes. Losers also committed more doubles faults than winners, and in the male category more unforced errors, whereas female winners get higher serve maximum speed (p< 0.05). Performance indicators according to the result of the match predicted that break points won, first serve points won (%) and first serve return points won (%) are the most relevant variables in males (SC= 0.434; SC= 0.340; SC= 0.327), whereas it was the break points won (SC= -0.372) in females. Therefore, coaches should consider the variation of the competition statistics by gender if they want to enhance the chances of success of their players
