Abstract

Cilj ovog istraživanja je utvrditi razlike u parametrima situacijske uspješnosti servisa i vraćanja servisa između igrača pobjednika i poraženih na Australian Openu 2019. godine. U radu je opisana povijest Australian Opena i tenisači koji su to prestižno natjecanje najviše puta osvajali. Osim toga opisane su neke od bitnih komponenata koje čine prevagu u uspješnosti vraćanja servisa.
Za potrebe ovog istraživanja korišteni su službeni podaci svih odigranih pojedinačnih susreta u glavnome dijelu ždrijeba Australian Opena 2019. godine. Uspoređene su varijable servisa i vraćanja servisa kod svih igrača pobjednika i poraženih u muškoj kategoriji u svim odigranim susretima u prva tri seta. Uzorak ispitanika čine statistički podaci odigranih susreta 128 igrača u glavnome dijelu ždrijeba. Uzorak varijabli u ovom istraživanju sastoji se od 11 parametara servisa i 11 parametara vraćanja servisa. Sve parametre je pratila infosys (službeni partner za digitalne inovacije) na Australian Openu 2019. godine. Za sve varijable izračunati su sljedeći parametri: aritmetička sredina (AS), standardna devijacija (SD), minimalna i maksimalna vrijednost (MIN i MAX). Razlike u parametrima situacijske uspješnosti servisa i vraćanja servisa između pobjednika i poraženih na Australian Openu 2019. godine određeni su t-testom za nezavisne uzorke. Rezultati ovog istraživanja su pokazali kako igrači pobjednici u parametrima situacijske uspješnosti servisa statistički imaju značajno više osvojenih poena nakon prvog servisa u svim setovima, te ukupno imaju više osvojenih poena u prva dva seta. Kod parametara situacijske uspješnosti vraćanja servisa igrači pobjednici se statistički značajno razlikuju u više komponenata od kojih treba izdvojiti ukupan broj osvojenih poena nakon vraćanja prvog i drugog servisa, te ukupan broj osvojenih poena nakon vraćanja servisa.

Abstract (english)

The aim of this research is to determine differences in the situational efficiency parameters of serve and return of serve between winners and defeated players at the 2019 Australian Open. The paper deiscribes the history of the Australian Open and players who have won this prestigious competition the most times. In addition, some of the essential components that distinguish the success of a returned service were described.
This research was based upon the official data for all played single matches in the main part of the 2019 Australian Open. Serve and return of serve statistics from the first three sets of each match were compared across all winners and defeated male players. The sample of participants in this research is based upon statistics from all played matches of the 128 players in the major part of the draw. The sample of variables in this research consists of 11 serve parameters and 11 return of serve parameters, which were evaluated by a infosys (official digital innovation partner) at Australian Open 2019. These parameters include: arithmetic mean (AS), standard deviation (SD), minimum and maximum value (MIN and MAX). Differences in the parameters of situational efficiency in serve and return of serve between winners and defeated players at the 2019 Australian Open were determined by the t-test for independent samples. The result of this research shows that winners in the parameters of service performance have a statistically significantly higher number of winning points after the first serve in all sets, with a total of more winning points in the first two sets. In the case of returning serve performance parameters, winners are statistically significantly different in the number of components, including the total number of points won after the first and second serve and the total number of points won after the return of the serve.
