Fig. 8From: Crucial role of androgen receptor in resistance and endurance trainings-induced muscle hypertrophy through IGF-1/IGF-1R- PI3K/Akt- mTOR pathwaySummary diagram. Endurance and resistance trainings could raise AR protein levels in the muscle, then activating IGF-1/IGF-1R- PI3K/Akt- mTOR pathway in the muscle to promote muscle hypertrophy of male rats, which explained the reason in part of training-induced muscle hypertrophy. The thin upward arrowheads stand for increase or promotionBack to article page
