Title: Relationship between game skills, physical fitness and self-efficacy in footbal players in relation to age. Objectives: Discover the interrelationship of self-efficacy, physical abilities and specific game skills in football players (13 - 19 years). At the same time, the objective is to verify the effect of age on the level of physical abilities, specific game skills and self- efficacy. Methods: The Czech version of the General Self-Efficacy (GSE) standard questionnaire was used to determine the level of self-efficacy. To determine the level of physical abilities and specific game skills, were used to diagnose and compare the level of football players in centers for the education of talented youth. A set of photocells (Alge Timing GmbH, Lustenau, Austria) was used to measure the 20 m sprint time, agility and ball slalom. The basic statistical characteristics (arithmetic mean, standard deviation) will be used to interpret the results. Standardization / normalization of values has been used with the help of Z-points for transferring results so that we can express the level of specific game skills with a single score. The Pearson correlation coefficient was used to evaluate the relationship between self-efficacy and football gaming skills. To evaluate the significance of the differences between...

Title: The assesment of intensity of physical load using heart rate in different types of preparatory games in football players. Objectives: Determine the intensity of physical load in different types of preparatory games within the training unit with professional football players. At the same time the aim is to determine possible differences in the intensity of physical load in different types of preparatory games because of the different player's positions. Methods: Sport tester "Polar RS800" was used to assess the intensity heart rate during the preparatory games in training unit. The research group consisted of professional football players (N = 8) who play the second highest senior competition. Results: In terms physical load was found to be substantively significant difference between the midfielders and defenders in the time spent above the anaerobic threshold. With midfielders and players on wings were found to be minor to moderate significant differences in time spent above the anaerobic threshold during the preparatory games. It is similar with midfielders and attackers which were found too minor to moderate significant differences in time spent above the anaerobic threshold during the preparatory games. . Keywords: Football, physical load, heart rate, preparatory game, player's positions.
