20.500.12556/RUL-137535 Comparison of the field-based intermittent running fitness test 30-15 and the treadmill multistage incremental test for the assessment of cardiorespiratory fitness in elite handball players The aim of the present study was to investigate whether the physiological parameters indicative of cardiorespiratory fitness obtained during the 30-15 intermittent fitness (30-15$_{IFT}$) test and the multistage laboratory treadmill endurance (TR) test differ. Nineteen elite handball players were recruited for the current study and assigned in a cross-over manner to one of two tests to be performed 48 h apart at each visit to the testing facility. The results showed that VO$_{2max}$ (percentage difference [PC] = 6.1%; p = 0.004) and maximal running velocity (V) (PC = 19.4%; p < 0.001) were significantly higher for the 30-15$_{IFT}$ test than that obtained during the TR test. Furthermore, the onset of blood lactate accumulation was shown to be significantly higher for all measures considered to predict it during 30-15$_{IFT}$ compared to TR as follows: VO$_{2max}$ (PC = 12.6%; p = 0.001), running speed (PC = 33.9%; p < 0.001), and maximal heart rate (PC = 7.5%; p < 0.001). The current study highlights the importance of sport-specific testing, particularly for measuring individual cardiorespiratory fitness in elite handball players, as TR may underestimate crucial variables used for both diagnostics and training prescription. maximal running speed aerobic endurance aerobic incremental field test laboratory treadmill test VO$_{2max}$ največja hitrost teka aerobna vzdržljivost VO$_{2max}$ tek aerobika kineziologija telesna pripravljenost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-21 10:22:32 2022-06-21 10:22:37 2022-09-15 04:15:21 0000-00-00 00:00:00 2022 0 0 10 str. iss. 6, art. 3535 Vol. 19 Mar. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.012.12 1660-4601 10.3390/ijerph19063535 101362691 ijerph-19-03535.pdf ijerph-19-03535.pdf 1 B037024FE9B756C9F75DB5ABB0B93A89 5c5343b104d9d9be6d58232dad7dea72e7aeafea4e84991a88054bb79313ba54 7261ae3c-f13b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157516 https://www.mdpi.com/1660-4601/19/6/3535 1 2051db54-f13b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157515 Fakulteta za šport 0 0 0
