La scienza
I tuoi risultati, con il supporto della scienza.
CAROL Bike è stata sviluppata insieme ai principali ricercatori dell’esercizio fisico per offrire gli allenamenti più brevi ed efficaci. Il nostro allenamento REHIT di punta crea lo stimolo più potente con soli 2×20 secondi di sprint. È scientificamente dimostrato che offre benefici superiori per salute e forma fisica rispetto al cardio tradizionale—nel 90% di tempo in meno.
Come funziona il percorso di adattamento REHIT
La personalizzazione con l’IA di CAROL ti aiuta a spingerti al limite durante gli sprint. Come in una situazione di ‘attacco o fuga’, i tuoi muscoli sono costretti a mobilitare circa il 25-30% del glicogeno muscolare—la tua riserva di energia di emergenza—liberando molecole di segnalazione fondamentali (AMPK e PGC-1a) che dicono al tuo corpo che deve diventare più in forma e più forte.
Sviluppi più mitocondri, il volume del plasma sanguigno aumenta e il cuore diventa più forte. Il risultato è una maggiore capacità aerobica e anaerobica.
