Standing two-leg raises ---------------------68%
Seated raises -------------------------------61%
la cosa è molto interessante e leggendo tra i numeri vengono fuori diverse considerazioni, ma mi vengono anche dei dubbi, primo tra tutti sono attendibili le rivelazioni con l'elettromiografo, cioè se c'e' scritto 80% significa che quell'esercizio stimola esattamente l'80% delle fibre? ma la percentuale non dipende poi da tremila altri fattori due su tutti il carico usato e la cadenza delle ripetizioni??
