Approximately 20 probands will be enrolled in the study based on voluntary participation from a group of players of the Charles University hockey team Prague, who have a valid medical examination with no restrictions on eligibility for selected sporting activities. The second group will consist of approximately 20 additional probands from the U20 age group of ice hockey players enrolled voluntarily with a valid medical examination with no restrictions on eligibility for the selected sporting activities.
