Dirt Bike Suspension Construction
Kučera, Vlastimil ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
Front suspension significantly influences the characteristics of the motorcycle, so it is necessary to deal with the problem. The bachelor thesis presents individual suspension functions, it describes and explains function of air spring and coil spring forks, analyzes the damping system and shows the options for settings of the forks. It compares the design of the forks used in production motocross motorcycles from 2016 and 2017 and refers to their potential advantages or disadvantages. The forks d iffer from each other mainly by the type of spring, and whether each leg contains spring and damper or they have a separate function. Each solution has its advantages and disadvantages, it depends mainly on the overall setting of the fork.

Professional first aid in motorcycle racings in the Czech republic and abroad
SEJK, Lukáš
This Bachelor thesis deals with providing of professional first aid during motorcycle races in Czech Republic and abroad. A notion "motorcycle races" in this work is narrowed down only to "sidecarcross". In this field there is a high risk of injury because of the variable nature of the track, weight and power of the machine. These injuries are most frequent causes of death of working-age people. Therefore it is so important to provide pre-hospital care immediately after any accident right on the track. The objective of this thesis is to map these types of races from the point of view of health insurance and to determine qualification of personnel at the place of accident. The thesis is compiled from semi-structured interviews at sporting venues. Interviews were conducted with two groups of respondents. The first was group of organisers of international championship races in Czech Republic and world championship. The second group was composed of medical personnel providing health care right at the tracks. The research has pointed out missing legislative support of this issue and the resulting disunity during providing sporting events.

Title: Nutritional aspects and body composition in motocross Objectives: The goal of this work is monitoring nutritional habits and parameters for the assessment of body composition and somatotype for Czech junior national team in motocross and enduro. Methotds: There was used four day record of consumed food to map out nutritional habits, which was evaluted by software Nutirs. The input data of body composition were obtained by Bioimpendance InBody 230. Following were also measured selected anthropometric parameters. Results: The results of our study indicate quantitative variations in motocross riders nutrition, especially the negative energy balance and the low proportion of carbohydrates in the diet in pre-season and in the day of the race. These can be some way influenced by individual variability. The research somatotype and body composition suggests that in relation to physical abilities are motocross riders and riders Enduro the most versatile talent for sport. Keywords: Motocross, nutrition, supplements, body composition, somatotype, bioelectrical impedance
