Tittle: Influence of skating technique on skating speed in players aged 8-10 Objektive: Search teoretic procedures for teaching skating and speed development in ice hockey in available literature. Then create and apply a set of exercises to improve skating techniques for the 8-10 year category. Use skating speed tests to verify the effectiveness of the exercises and demonstrate the effect of the skating technique on skating. Works: - Look for theoretical techniques for skating techniques and ice hockey. - Create and apply a set of exercises to develop ice skating techniques. - Use skating speed tests to verify the effectiveness of the selected exercises. - Compare the test results between three teams with a different volume of skating training. Results: Find out the effect of skating technique on skating speed. Hypotheses: 1. Players aged 8-10 will have comparable lead times in each test in all three teams. 2. Speed skating can be developed by improving skating techniques. 3. More skating training means more improvement in skating speed. Key words: Ice hockey, skating, skating speed, skating technique, 8-10 years.

Title: Speed Skating arena and public attitude to its construction Objectives: The main aim of the diploma thesis is the analysis of a project of a speed-skating rink in Velky Osek. Citizens from Kolin and Nymburk regions, as well as Prague, have been polled on the possible rink construction. Citizens have been surveyed on their foreknowledge and the future possibility of the of grounds usage. Methods: A descriptive analysis was used to comment on data gathered in relationship to the proposed construction of a speed-skating rink. Furthermore, a SWOT analysis was used in order to evaluate the direct external and internal impact the proposed construction of a speed-skating rink in Velky Osek (Kolin region). A quantitative survey (questionnaire) has been used in polling citizens on their attitude toward the possible construction of the rink. Results: The results have shown the heterogeneity of the attitudes of the citizens. However, we may conclude that there are more people who support the idea ofconstructing a speed-skating rink in the Czech Republic, rather than the proposed construction project in Velky Osek.

The purpose of this study was to establish the reliability and validity of the Power Master isokinetic ergometer in measuring skating power for 34 hockey players (14 professional, 11 recreational, and 9 female university players). Comparisons between two on-ice tests and four laboratory tests of skating speed and power, and prediction of sprint skating speed were also examined for 19 hockey players (10 recreational and 9 female university players). The Power Master displayed internal consistency reliability, construct validity, and criterion related validity. Significant correlations occurred between the on-ice tests and the laboratory test (r =.55 to r =.95), and the Power Master was a significant variable in predicting sprint skating speed. It was concluded that the Power Master is a reliable and valid machine for the measurement of skating power in hockey players.

The purpose of this study was to determine the physiological response of an in-line submaximal skate on two surfaces using two wheel types and two bearing types. The variables measured were V0$ sb2$ and HR. Ten male varsity hockey players volunteered as subjects. The subjects, after being assigned one of two wheel types with varying durometers, skated the submaximal test twice for each surface (concrete and asphalt) using a different type of bearing (precision and semi-precision) each time. These results were compared to a similar on-ice submaximal skating test session. / Results revealed no significant difference between in-line skating with wheels of 78 and 82 Shore A durometers (p $<$.05) with both V0$ sb2$ and HR as markers. A significant difference was found between in-line skating with precision and semi-precision bearings with V0$ sb2$ as a marker (p $<$.05), however, not with HR as a marker (p = 0.31). On-ice skating was significantly different from in-line skating on concrete and asphalt surfaces for both physiological markers. In-line skating on asphalt and concrete surfaces resulted in similar physiological responses. It was concluded that hockey players training with in-line skates obtain the same training benefits using either wheel durometers, but will have greater oxygen costs when training with semi-precision bearings than training with precision bearings.

Objectives. The purpose of this study was too determine whether there were significant kinematic differences between recreational and elite hockey players and between contra-lateral lower limbs during forward hockey skating. / Methods. While skating on a hockey treadmill subjects were filmed with four synchronized digital video cameras while wearing reflective marker triads on the thighs, shanks and skates. Subjects skated within a calibrated volume at a self selected speed that they could maintain comfortably for one minute. Each subject completed three trials separated by 5 minutes of rest. Data was reduced and analyzed using programs written in MATLAB. Two-way ANOVA and Tukey Post Hoc tests were used to determine statistic significance. / Results. Elite and recreational subjects were significantly different (p≤0.05) during knee abduction and knee rotation at push off, as well as during knee abduction and knee flexion at blade contact. Contra lateral lower limbs were significantly different (p≤0.05) during ankle abduction and hip rotation at blade contact as well as during knee abduction at push off. / Conclusion. Some aspects of the skating stride are similar in elite and recreational hockey skaters but there were several kinematic differences between skill levels and contra-lateral legs. The skating kinematics of elite hockey players may serve as a model for young hockey players and recreational hockey players, helping them develop a more efficient and effective stride.
