Comparison of load during diagonal striding and double poling on the roller ski during sprint
Čechová, Anna ; Suchý, Jiří (advisor) ; Gnad, Tomáš (referee)
Title: Comparison of internal loading on the organism by double poling and diagonal striding during the sprint on the roller ski Objectives: The aim of the diploma thesis is to compare the internal loading using the Cortex Metamax 3B and the SenzoStar GL devices in a two-hundred meters long section performed by the maximum effort between the double poling and diagonal striding about the 10.4% climb on roller skis. Methods: The diploma thesis is conceived as an empirical field research, the aim of which is to compare a double poling and diagonal striding in terms of internal loading on roller skis during sprint. The test subject will be a group of cross-country skiers and long-distance skiers. Results: Using the measured values of the internal loading and the measured time, we found differences during comparing the diagonal striding and double polling in specific values of SF, VO2 / kg, VE. the conclusion was that diagonal striding is faster than double poling to the uphill on roller skis. Keywords: XC-skiing, roller skis, Cortex MetaMax 3B, oxygen consumption, heart rate, lactate

Specific exercises on roller skis for nordic skiers (12-14 old)
Korbelář, Tomáš ; Suchý, Jiří (advisor) ; Gnad, Tomáš (referee)
Title: Specific roller skis' games and acitivities for young nordic skiers aged between 12 and 14 years Goal: Create and verify a collection of games and activities by experts on the rollers skis'for young nordic skiers aged between 12 and 14 years. Methods: A first method used in this work was available analysis of czech and international documents about games and activities. Then a collection of games and activities was made, which was customised for roller skis trainings. Furthermore, there was a verification of collection of roller skis'games and activities with the help of a board of experts composed of experienced and licensed nordic skiers'trainers and then nordic skiers'experts. An unstructured interview was made with them followed by a discussion about each game and activity. Results: In the first part there is a chapter about an equipment used collection created by us. The main part is made of a customised and verified collection of roller skis'games and activities for young nordic skiers aged between 12 and 14 years. Board of experts made a verification added their ideas and suggestions to specific games and activities in the form tips and suggestion. A new chapter dividing the collection was created as a result of a discussion with the board of experts was created at the end of a final...

Comparison of load during diagonal and striding double poling on the roller ski
Čechová, Anna ; Suchý, Jiří (advisor) ; Gnad, Tomáš (referee)
Title: Comparison of training impact of striding versus double poling for cross country skiing. Objectives: The goal of the research is to find out and compare the difference between striding and double poling from the point of view of internal body impact, or lactate acid, heart rate and measured time of the performance in two consecutive days, respectively. Methods: This research is conceived as an empiric field research, which considers a comparison of lactate acid (LA) levels during cool down and heart rate (SF). Compared values were measured on roller skis in two consecutive days. Results: With the help of lactate acid levels, heart rate and measured times we found the main differences between striding and double poling. To the conclusion, we found out that striding was faster from measured time perspective and also the lactate acid levels were lower than for double poling. Keywords: Cross-country skiing, roller skating, heart rate, lactate, diagonal striding, double poling.

The difference in load of the body between the rides on roller skis and cross-country skis.
Franc, Jan ; Gnad, Tomáš (advisor) ; Jindra, Matouš (referee)
Title: The difference in load of the body between the rides on roller skis and cross-country skis. Objectives: The aim of work is to determine the difference in load of the body between the rides on roller skis and ride on cross-country skis in skating and classic techniques. Methods: The work is conceived as a case study. It is a quantitative research carried out on the basis of comparing the values of heart rate and blood lactate concentration at one participant. The values were compared between the roller and cross-country skis when skating as well as classical techniques. Results: By the heart rate measuring and lactate concentration, the difference was detected between the roller and cross-country skis. We came to the result that the roller skis place less demands on the load of the body than cross- country skis which runners use to ski in winter. Keywords: cross-country skiing, cross-country skis, roller skis, lactate, heart rate
