Bakalarska prace je zamerena na vlivu her malych forem na vnitrni zatizeni organismu u hracu fotbalu v kategorii U19 behem treninkovych jednotek. Vyzkumny soubor tvorilo 9 profesionalnich ceskych hracu s prumernym vekem 18,44?0,30 roku. V ramci mereni potrebnych hodnot byl vyuzit system Polar Team2Pro, ktery poskytnul cenne informace o vnitrnim zatizeni organismu v prubehu her malych forem. Tyto hry jsou predlozene v druhe casti prace. Hry jsou nakresleny a popsany. Nasledne je zmineno, ktere pomucky jsou vhodne k realizaci a jaky je potreba zvolit interval zatizeni k dosazeni potrebnych hodnot srdecni frekvence. Tyto hry a jejich hodnoty mohou slouzit pro aktualni moderni trendy ve fotbalovem treninku.The bachelor thesis focuses on the influence of small forms games on the internal load of the organism in football players in the U19 category during training units. The research group consisted of 9 professional Czech players with an average age of 18,44?0.30 years. As part of the measurement of the necessary values, the Polar Team2Pro system was used, which provided valuable information about the internal load of the organism during small-form games. These games are presented in the second part of the work. Games are drawn and described. Subsequently, it is mentioned which aids are suitable for implementation and what load interval needs to be selected to achieve the necessary heart rate values. These games and their values can serve for current modern trends in football training.
