title="Relationship between vertical jump tests and ice-skating performance in junior Polish ice hockey players",
abstract="The aim of this study was to determine the relationships between vertical jumps (VJ) and various  on-ice skating performances of junior ice hockey players (n = 19). The three modes of VJ or off-ice measures  were countermovement jump with arm swing (CMJ), squat jump (SJ) and depth drop jump (DDJ). The on-ice  skating performance was measured by the skating multistage aerobic test (SMAT), forward and backward  acceleration test, top speed test, and repeated sprint ability (RSA) test. The relationships between the variables  were quantified using Pearson’s product-moment correlation. DDJ showed a significant positive correlation with  forward average skating speed (FASS) (r = 0.62) and strong correlations with backward average skating speed  (BASS) (r = 0.81), and maximum skating speed (MSS) (r = 0.71). SJ was found to be strongly correlated with  BASS (r = 0.82) and MSS (r = 0.76), whereas the only on-ice performance that significantly correlated  with CMJ was BASS (r = 0.68). All three modes of VJ were inversely and non-significantly correlated with  performance decrement index and fatigue index, as determined by the RSA test. SMAT was not significantly  correlated with either VJ or RSA. Correlations between all three modes of VJ tests were significant. Therefore,  this study concludes that: (1) DDJ can be used as a predictor of all the ice skating speed tests, whereas SJ can  predict BASS and MSS. CMJ, on the other hand, can predict the performance of only BASS. (2) RSA performance  cannot be predicted from CMJ, SJ, or DDJ tests, and (3) neither any of the VJ nor RSA can predict skating  endurance of junior ice hockey players.",
