Abstract

Lo scopo del presente studio era di determinare gli effetti combinati del consumo di integratori HMB-FA e di una sessione di allenamento di resistenza estrema sul tasso di attivazione delle cellule satellite di ratti maschi maturi. A tale scopo, una volta effettuati gli studi preliminari, ottanta ratti maschi Sprague Dowley (gruppo di controllo: 18 ratti; gruppo HMB: 19 ratti; gruppo esercizio: 19 ratti; gruppo esercizio + HMB: 19 ratti) con otto settimane e peso di Per lo studio sono stati selezionati 200 ± 20 grammi. Dopo il corso di familiarizzazione con le scale, è stata avviata e mantenuta l'assunzione giornaliera di integratori per tre settimane. Una volta che i ratti hanno familiarizzato con la scala e ricevuto il supplemento per tre settimane, è stata somministrata una sessione di allenamento di resistenza. Il protocollo di allenamento includeva la discesa di una scala con un'inclinazione dell'80% mentre un peso del 100-110% 1RM era attaccato alla coda dei topi. I risultati dell'estrazione dell'RNA e dell'immunoistochimica hanno mostrato che i tre interventi sperimentali hanno determinato un aumento dell'espressione dei geni MyoG e CD56 nel tricipite. Il punto importante, tuttavia, era che l'intervento più efficace era l'esercizio + intervento HMB. Le quantità di geni CD56 e MyoG erano statisticamente significativamente aumentate nei gruppi HMB, Esercizio ed Esercizio + HMB (p = 0,001). Secondo i risultati ottenuti, il consumo di integratore HMB in combinazione con l'esecuzione di esercizi eccentrici può svolgere un ruolo efficace nell'attivazione, proliferazione, propagazione e differenziazione delle cellule satelliti. Infatti, gli atleti e il personale militare che in alcuni momenti si dedicano a un'attività fisica faticosa e utilizzano un allenamento preparatorio estremo per massimizzare la propria prontezza fisica possono utilizzare l'integratore HMB contemporaneamente al proprio allenamento e ottenere risultati ancora più efficienti.
