“…In our case, the players are in apparently the best ice hockey league in the world and therefore it is desirable to know the exact parameters of the current players, especially with respect to their gaming positions (Quinney et al, 2008;Stanula, Roczniok, Maszczyk, Pietraszewski, & Zajac, 2014;Vescovi, Murray, & VanHeest, 2006). Basic morphological parameters, together with the knowledge of body composition, development of strength in the upper and lower body parts, and optimum development of aerobic (VO 2 max scores ± 56-60 ml/kg/min) and anaerobic capacity (AnC) (total AnC of elite ice hockey players is ± 1100-1200 W; relative AnC/kg of elite ice hockey players is ± 13 W/kg) are considered the main prediction factors of possible success and performance, especially in young players entering the Canadian-American NHL (Garrett & Kirkendall, 2000;Montgomery, 2006;Peyer, Pivarnik, Eisenmann, & Vorkapich, 2011;Potteiger, Smith, Maier, & Foster, 2010;Tarter et al, 2009). If the overall index of the above mentioned prediction factors is around the 90 th percentile, there is a 60-72% probability that a young ice hockey defender or forward will join an NHL team during the following four years (Tarter et al, 2009).…”
