20.500.12556/RUL-132830 Acute effects of a speed training program on sprinting step kinematics and performance The purpose of this study was to examine the effects of speed training on sprint step kinematics and performance in male sprinters. Two groups of seven elite (best 100-m time: 10.37 ± 0.04 s) and seven sub-elite (best 100-m time: 10.71 ± 0.15 s) sprinters were recruited. Sprint performance was assessed in the 20 m (flying start), 40 m (standing start), and 60 m (starting block start). Step kinematics were extracted from the first nine running steps of the 20-m sprint using the Opto-Jump–Microgate system. Explosive power was quantified by performing the CMJ, standing long jump, standing triple jump, and standing five jumps. Significant post-test improvements (p < 0.05) were observed in both groups of sprinters. Performance improved by 0.11 s (elite) and 0.06 s (sub-elite) in the 20-m flying start and by 0.06 s (elite) and 0.08 s (sub-elite) in the 60-m start block start. Strong post-test correlations were observed between 60-m block start performance and standing five jumps (SFJ) in the elite group and between 20-m flying start and 40-m standing start performance and standing long jump (SLJ) and standing triple jump (STJ) in the sub-elite group. Speed training (ST) shows potential in the reduction of step variability and as an effective short-term intervention program in the improvement of sprint performance. sprinting speed sprint exercises step variability kinematics teki trening program sprint hitrost kinematika moški true false true Angleški jezik Slovenski jezik Članek v reviji 2021-11-04 10:42:58 2021-11-04 10:42:59 2022-09-12 04:13:55 0000-00-00 00:00:00 2019 0 0 13 str. iss. 17, art. 3138 Vol. 16 sep. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.422.12 1660-4601 10.3390/ijerph16173138 5578929 RAZ_Mackała_Krzysztof_2019.pdf RAZ_Mackała_Krzysztof_2019.pdf 1 A076C8739B4FEA16A5CB4975D55EA5C4 d63b4812a0539e7cb17ecb3f68cee4a060996149df6e81714c556970038ef6e9 f31cc546-3d53-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150550 https://www.mdpi.com/1660-4601/16/17/3138 0 8d0fbcab-3d53-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150549 Fakulteta za šport 0 0 0
