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...

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
