Differences in the anaerobic power output of the four age categories of basketball players

Primarni cilj ovog istraživanja bio je izmjeriti mehanički izlaz snage Margaria-Kalamen testom, te utvrditi razlike između četiri dobne kategorije košarkaša košarkaškog kluba „Virka“ iz Virovitice. Istraživanje je provedeno na uzorku od 40 ispitanika koji nastupaju u četiri dobne kategorije: M-15 (n = 10; dob: 13,7 ± 0,46; tjelesne mase 62,1 kg ± 12,71 kg; visina 175,4 cm ± 7,8 cm), M-17 (n = 10; dob: 15,7 ± 0,48; tjelesne mase 75,7 kg ± 8,1 kg; visina 188 cm ± 4,45 cm), M-19 (n = 10; dob: 17,6 ± 0,52; tjelesne mase 77,2 kg ± 13,9 kg, visina 188,8 cm ± 8,9 cm) i SENIORI (n = 10; dob: 27,5 ± 5,17; tjelesne mase 91,9 kg ± 10,6 kg, visina 192,3 cm ± 7,7 cm). Uvjet uključenosti u istraživanje je bio da su košarkaši aktivni natjecatelji u pojedinim dobnih kategorijama. Osim mjerenja osnovnih antropoloških karakteristike kao što su visina i masa tijela, ispitanicima je izmjerena snaga koja se procijenila Margaria-Kalamen testom i vrijeme koje je ispitaniku potrebno da prijeđe put između treće i devete stepenice prilikom izvođenja testa. Pretpostavka je bila da dob ispitanika značajno utječe na rezultate Margaria-Kalamen testa, gdje stariji imaju značajno bolje rezultate od mlađih ispitanika. Rezultati su pokazali da dobna kategorija M-15 ima nabolje prosječno vrijeme Margaria-Kalamen testa (0,53 ± 0,05 s), dok su SENIORI postigli najbolje rezultate u mehaničkom izlazu snage (1556,2 ± 142,49 W). The primal goal of this study was to measure the anaerobic power output by Margaria-Kalamen test and to determine the differences between the four age categories of basketball players of the basketball club „Virka“ from Virovitica. The survey was conducted on a sample of 40 respondents performing in four age categories: M-15 (n = 10; age: 13.7 ± 0.46; body weight 62.1 kg ± 12.71 kg; height 175.4 cm ± 7.8 cm), M-17 (n = 10; age: 15.7 ± 0.48; body weight 75.7 kg ± 8.1 kg; height 188 cm ± 4.45 cm), M-19 (n = 10; age: 17.6 ± 0.52; body weight 77.2 kg ± 13.9 kg, height 188,8 cm ± 8,9 cm); SENIORS (n = 10; age: 27.5 ± 5.17; body weight 91.9 kg ± 10.6 kg, height 192.3 cm ± 7.7 cm). The condition of inclusion in the research was that basketball players were active competitors in certain age categories. In addition to measuring basic anthropological characteristics such as height and body weight, subject measured the strength assessed by Margaria-Kalamen test and the time it took a subject to run between the third and ninth stair when performing the test. The assumption is that the age of the respondents significantly affects the results of the Margaria-Kalamen test, where the older subjects have significantly better results than the younger. The results showed that the group M-15 has the best average time of the Margaria-Kalamen test (0.53 ± 0.05 s), while the SENIORS achieved the best results in the anaerobic power output (1556.2 ± 142.49 W).
