DOI 10.26773/smj.230207Sport Mont 21 (2023) 1: 43-47 43Elite and Sub-elite Youth Soccer Players Showno Difference in Vertical Jump PerformanceMaros Kalata 1, Matej Varjan1, Mikulas Hank1, Lucia Mala1, Osman Imal1, Jana Marketin11Charles University, Faculty of Physical Education and Sport, Prague, Czech RepublicAbstractThis study aimed to determine whether vertical jump performance differs among youth players with different perfor-mance levels. A total of 84 youth male soccer players from the U19 category were recruited. The players were divided intothe elite (EG) and sub-elite (SEG) groups based on their performance level. The vertical jump (VJ) performance duringcountermovement jump with free arms (CMJFA) and drop jump (DJ) were measured using two force platforms KistlerB8611A at a sampling rate of 1000 Hz (KISTLER Instrumente AG, Switzerland). The following outcome variables werecalculated in all participants: vertical jump height (VJH), vertical ground reaction force (VGRF), and force impulse (FI)in absolute and relative values. Data analysis showed no significant differences (p&gt;0.05) with trivial to small effects in VJHfor both jump types (CMJFA and DJ) between EG and SEG. FIrelative provides a good indication of VJH in comparison withthe other kinematic variables selected in this study. The leg muscle mass (LMM) ratio normalised to body mass providesa better association with VJH than the other selected morphological variables in this study, although a small effect sizewas observed. VJH does not appear to be a distinguishing feature among soccer players in the first two performance levelsin the U19 category. Therefore, the results may not be sensitive enough to differentiate the performance levels, especiallywhen the difference is only in one performance level. Future research should consider using other parameters, such as theeccentric rate of force development or reactive strength index, as recommended in a previous study.
