Skridskoåkning är en avgörande faktor för prestation i ishockey och styrka (i nedre extremitet) är i sin tur avgörande för hur snabb spelaren är på isen. Syftet med denna studie är att undersöka sambandet mellan power off-ice och skidskosnabbhet på is. Sju män 19.5 ± 0.5 år vid ett gymnasium ställde upp i studien och genomförde ett testbatteri bestående av Ishockeyförbundets styrketester samt Effektmätning vid knäböj. Variabler i dessa styrketester korrelerades sedan mot deltagarnas resultat i skridskotestet Acceleration & Speed för att bestämma vilka styrkevariabler som är relevanta för skridskosnabbhet. Resultaten visade signifikanta samband mellan absolut styrka i frivändning och tid på total skridskosträcka (ρ=0.77, p<0.05) samt hastighetssträckan (ρ=0.77, p=<0.05). Signifikant samband kunde även påvisas mellan relativ styrka i frivändning och hastighetssträckan (ρ=0.71, p<0.05). Slutsatsen av denna studie är att delar av testbatteriet är relevant för att anskaffa information om en spelares maximala åkhastighet. / Skating is a key factor for a successful ice hockey player and strength in the lower extremity is therefore a crucial factor for determination of a players speed on the ice. The purpose of this study was to investigate the correlation between power, tested off-ice, and skating speed on ice. Seven male ice hockey players aged 19.5 ± 0.5 years were recruited from a local highschool. They completed a test battery consisting of the Swedish Ice hockey associations strength tests and power measurements in squat. In order to determine which strength variable is the most relevant to skating speed the strength variables were correlated to the results in a skating test called Acceleration and Speed. The results showed significant correlations between 1RM in clean and time on total distance (ρ=0.77, p<0.05) and velocity (ρ=0.77, p=<0.05) in the skating test. A significant correlation was also found between relative strength in clean and velocity (ρ=0.71, p<0.05). The conclusion of this study was that parts of the testing battery is relevant for use when collecting information on a players maximum skating speed.

Title: Relation between selected off-ice tests and performance in on-ice Illinois Agility test of ice hockey players between 14-17 years old in Czech elite category. Objectives: The main goal of this thesis was to determine whether the somatotype and selected off-ice tests are significant predictors for performance in the on-ice agility test in ice hockey players in the youth elite category. Methods: The research group consisted 28 ice hockey players (8 forwards and 18 defenders) x̅ = 14,88 ± 0,57. Players played highest youth league during the measurement period. The method of Heath and Carter (1990) was used to determine the somatotype. Squat Jump, Countermovement Jump, Free Arm Countermovement Jump, Sit and Reach, pull-ups and off- ice Illinois Agility with a ball were used as off-ice tests. The Aspin-Welch two-samle T-test with Effect size (ES) Hedges' g was used to evaluate the degree of difference in performance between forwards and defenders. Pearson's correlation coefficient with ES coefficient of determination R2 was applied to determine the tightness of relationships between selected variables. Evaluation of the significance of predictors for performance in on- ice agility tests was performed through multiple regression analysis. The significance of the model was assessed according to the...

Title: Relation between selected off-ice tests, somatotype and performance in on-ice Illinois Agility tests in junior ice hockey players from Czech elite category. Objective: The aim of this thesis was to verify whether the somatotype and off-ice tests are significant predictors for performance in on-ice agility tests in junior ice hockey players from Czech elite category. Methods: The research sample consisted of 32 junior hockey players (17 defenders and 15 forwards) ̅ = 17.64 ± 1.02 from Czech elite category. The Heath and Carter (1990) method for measuring of somatotype was used. The off-ice tests included Squat Jump, Countermovement Jump, Free Arm Countermovement Jump, Broad Jump, Five-Jump test, Sit and Reach, Pull-ups and off-ice Illinois Agility with (small size) ball. Further, on-ice Illinois Agility with puck and Illinois Agility without puck were used as dependent variables. The differences in performance between defenders and forwards were analysed by Aspin-Welch's two-sample T-test with Effect size (ES) Hedges's g. The degree of significance of the predictors for dependent variables in on- ice agility tests was assessed by multiple regression analysis with significance of model at the level of p<0.05 and ES described as adjusted R2 . Results: Comparison of the results achieved by...
