| Abstract | Budući da servis i vraćanje servisa čine skupinu tehničko-taktičkih elemenata od kojih ovisi uspjeh u teniskom meču, cilj ovog istraživanja je utvrditi razlike u parametrima situacijske uspješnosti servisa i vraćanja servisa između igrača pobjednika i poraženih na Roland Garrosu 2021. godine. Uzorak ispitanika čine 128 igrača koji su se plasirali u glavni ždrijeb turnira u muškoj konkurenciji. Uzorak varijabli sastoji se od ukupno 16 varijabli koje su podijeljene na parametre servisa i parametre vraćanja servisa. Razlike između parametara situacijske efikasnosti servisa između igrača pobjednika i poraženih utvrđene su t-testom za nezavisne uzorke. Rezultati su pokazali kako u prvom setu kod pobjednika broj dvostrukih pogrešaka u prosjeku iznosi (0,94 ± 1,05) dok je kod poraženih to (1,25 ± 1,09) pogrešaka. Također, rezultati pokazuju kako poraženi imaju veći broj ubačenih drugih servisa od pobjednika, ali da pobjednici ipak postižu značajno veći broj poena (14,46 ± 4,52) nakon ubačenog drugog servisa u odnosu na poražene igrače (12,6 ± 5,19). Ono što je očekivano i u skladu s dosadašnjim istraživanjima je da pobjednici postižu veći broj osvojenih servis gemova (4,1 ± 1,02) i break lopti (1,58 ± 0,98) u odnosu na poražene u prvom setu (3,2 ± 1,52 i 0,72 ± 0,78). U drugom setu dobiveno je da pobjednici postižu statistički značajno bolje rezultate u broju as udaraca (2,16 ± 2,02) u odnosu na poražene (1,58 ± 1,61). Nadalje, vidljivo je kako poraženi imaju veći broj ubačenih prvih i drugih servisa (30,84 ± 8,34) u odnosu na pobjednike (28,7 ± 8,09), a to je dobar pokazatelj kako igrači pobjednici bolje vraćaju servis. Najmanja razlika između igrača pobjednika i poraženih javlja se u trećem setu gdje su razlike vidljive samo u parametrima vraćanja servisa gdje igrači pobjednici postižu bolje rezultate. Ono što je zanimljivo da su u trećem setu najveće razlike između igrača pobjednika i poraženog u varijablama vraćanja servisa. Tako igrači pobjednici postižu značajno veći broj osvojenih poena nakon vraćenog prvog i drugog servisa. Također, pobjednici imaju veći broj osvojenih break lopti (1,52 ± 0,94) u odnosu na poražene igrače (0,76 ± 0,85). |
| Abstract (english) | Since service and service return constitute a group of technical-tactical elements on which success in a tennis match depends, the aim of this study is to determine differences in the parameters of situational service success and service return between winning and losing players at Roland Garros 2021. The sample of respondents consists of 128 players who placed in the main draw of the tournament in the men's competition. The sample of variables consists of a total of 16 variables that are divided into service parameters and service return parameters. Differences between service situational performance parameters between winning players and losers were determined by t-test for independent samples. The results showed that in the first set, the number of double faults in the winners averaged (0.94 ± 1.05), while in the losers up to (1.25 ± 1.09) the error. Also, the results show that the losers have a higher number of inserted other services than the winners, but that the winners still score a significantly higher number of points (14.46 ± 4.52) after the second serve was inserted compared to the defeated players (12.6 ± 5.19 ). What is expected and in accordance with previous research is that the winners achieve a higher number of won game services (4.1 ± 1.02) and break balls (1.58 ± 0.98) compared to the losers in the first set (3.2 ± 1.52 and 0.72 ± 0.78). In the second set, the winners achieved statistically significantly better results in the number of strokes (2.16 ± 2.02) compared to the losers (1.58 ± 1.61). Furthermore, it can be seen that the losers have a higher number of inserted first and second services (30.84 ± 8.34) compared to the winners (28.7 ± 8.09), which is a good indicator of how the winning players return the service better. The biggest difference between the winning players and the losers occurs in the third set where the differences are only visible in the service return parameters where the winning players achieve better results. What is interesting is that in the third set, the biggest differences between the winning player and the loser are in the variables of service return. Thus, the winning players score a significantly higher number of points after returning the first and second serve. Also, the winners have a higher number of break points won (1.52 ± 0.94) compared to the lost games (0.76 ± 0.85). |
