Manifestations of neuromuscular fatigue due to repeat sprint ability during recovery after football match in U15 category

Abstract:

Diplomova prace se venuje komparaci vlivu neuromuskularni unavy na vykon hracu fotbalu v kategorii U15 behem utkani 10+1 a nasledne prubehu zotaveni behem 72 hodin po utkani. Vyzkumny soubor tvorilo 16 elitnich ceskych fotbalistu s prumernym vekem 14,78 roku. Prostrednictvim systemu Polar Team2Pro byly analyzovany ukazatele vnejsiho zatizeni a vnitrni odezvy organismu. Nasledne byl, jako stezejni vyuzit Countermovement jump test, zjistujici uroven neuromuskularni unavy. Porovnavany byly prumerne hodnoty hracu v dobe pred a po utkani, nasledne byla sledovana unava v casovem horizontu 72 hodin po utkani. Taktez byly sledovany jednotlive herni posty a jejich odlisnosti vzhledem k neuromuskularni unave. Komparaci ukazatelu byly zjisteny vyznamne rozdily (p <,05) v hodnotach vysky vyskoku hracu pri CMJ testu pred utkanim a po utkani. Vyzkum naopak neprokazal vyznamne rozdily (p <,05) v hodnotach vysky vyskoku pri CMJ testu s odstupem 48 hodin po utkani, jak z hlediska jednotlivych postu, tak celkoveho souboru hracu spolecne. Vysledky jsou vyuzitelne v souvislosti s aktualnimi trendy sportovniho treninku ve fotbale.

Abstract:

The thesis is devoted to the comparison of the influence of neuromuscular fatigue on the performance of U15 football players during a 10+1 match and then the recovery process during 72 hours after the match. The research population consisted of 16 elite Czech football players with an average age of 14.78 years. The Polar Team2Pro system was used to analyze the indicators of external load and internal body response. Subsequently, the Countermovement jump test was used as the main test to determine the level of neuromuscular fatigue. The average values of the players in the pre- and post-match periods were compared, followed by fatigue at a time point of 72 hours after the match. Also, individual playing positions and their differences with respect to neuromuscular fatigue were monitored. By comparing the indices, significant differences (p <.05) were found in the values of the players' jump height and RSI in the CMJ test before and after the game. Conversely, the study showed no significant differences (p <.05) in the values of jump height and RSI during the CMJ test 48 hours after the match, both in terms of the individual posts and the total set of players together. The results are useful in the context of current trends in sports training in football.
