Abstract

Il nostro studio mirava a identificare i meccanismi di azione/rimozione del lattato in una situazione di esercizio estenuante e a monitorare come progredisce l'indolenzimento muscolare a insorgenza ritardata (DMT) come risultato del processo di affaticamento metabolico installato. Gli esercizi su un tapis roulant computerizzato e un cicloergometro sono stati eseguiti durante una lezione di biochimica dell'esercizio, con raccolta del lattato in vari momenti dopo l'esercizio. Per valutare DMT, è stata utilizzata una percezione soggettiva della scala DMT. C'è stato un aumento significativo (p<0,001) nella concentrazione di lattato immediatamente dopo lo sforzo per entrambi i modelli di esercizio, con ritorno vicino ai livelli normali in 1 ora dopo l'esaurimento. La manifestazione del dolore ha avuto il suo apice tra le 24 e le 72 ore dopo l'esercizio, il che ha portato gli studenti a capire che esistono diverse strategie di recupero metabolico dopo l'esecuzione di un esercizio intenso.
