Abstract

Il presente studio si propone di verificare il livello di disidratazione nei giovani calciatori, confrontando le variazioni di massa corporea, acqua corporea totale per impedenza bioelettrica e volume plasmatico, dopo una partita di calcio della durata di 90 minuti. Nove giocatori di una squadra di calcio giovanile nello Stato del Paraná, con un'età media di 18,44 ± 1,24 anni, hanno partecipato a questo studio. Lo studio è stato condotto prima, durante e dopo una partita di calcio, dove i giocatori sono stati sottoposti a una valutazione prima e dopo la partita, che consisteva in: raccolta di massa corporea, altezza e impedenza bioelettrica tetrapolare per ottenere dati sull'acqua corporea totale in litri, dove è stata verificata anche la percentuale di grasso corporeo. È stato inoltre prelevato un campione di sangue prima e dopo la partita di calcio per verificare il livello di disidratazione attraverso la variazione del volume plasmatico. Dopo la valutazione iniziale, l'assunzione di liquidi e l'escrezione urinaria sono state controllate fino alla seconda valutazione, eseguita dopo la partita. L'analisi statistica ha mostrato un livello di disidratazione in tutti i metodi monitorati. In conclusione, si può vedere che i giocatori hanno avuto una perdita d'acqua, ma solo uno dei giocatori ha avuto una riduzione del volume plasmatico, compromettendo le prestazioni. Ulteriori studi dovrebbero essere effettuati con temperature diverse, oltre a valutare la posizione di ciascun giocatore individualmente, osservando il loro spostamento durante la partita.
