Somatotype and off-ice performance as predictors for long term hockey perspective in youth ice hockey players
Pilná, Petra ; Musálek, Martin (advisor) ; Vojta, Zdeněk (referee)
Title: Somatotype and off-ice performance as predictors for long term hockey perspective in youth ice hockey players. Objectives: The aim of this thesis was to determine whether a player's somatotype and performance in selected off-ice tests predict a player's hockey perspective judged by coaches in youth hockey of the highest domestic competition. Methods: The thesis included 112 hockey players in highest youth league. The off-ice tests included 1. Illinois agility, 2. Illinois agility with a ball, 3. Five jump test, 4. Sit and Reach Flexibility Test, 5. Squat Jump, 6. Free Arm Countermovement Jump, 7. Pull ups, 8. 1500 m run. The somatotype was evaluated according to the method of Heath and Carter (1990). The analysis of variance with repetition was used to compare performances over time with respect to somatotype categorization. A paired T-test with a confidence level of 95 % (p < 0,05) was used to assess potential within-survey. Cohen's d was used for the paired T-test to estimate the clinical significance (effect size), with Cohen's d ≤ 0.3 determined as the clinically significant effect size. To estimate the degree of influence of the selected off-ice tests on game perspective was assesed by multiple regression analysis with significance p < 0,05 and adjusted R2. Results: The only significant...

Relation between selected off ice tests, somatotype and performance in on-ice Illinois Agility tests in junior ice hockey players from Czech elite category
Slavíček, Tobiáš ; Musálek, Martin (advisor) ; Šťastný, Petr (referee)
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...

The significance of link between selected off ice tests and agility ilinoa on ice test in youth ice hockey players from the highest Czech competition
Chvátal, David ; Musálek, Martin (advisor) ; Šťastný, Petr (referee)
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...
