I don't know where you heard the rumor, watching wcba and women's volleyball, basketball strength is mostly upper limb strength, not calf strength, so let's not talk about women's volleyball. Look at the photos, the round and slender thighs and calves are really eye-catching. Compared with girls' legs in the whole sports world, high jump and track and field have the thinnest calves, followed by volleyball and basketball. Generally speaking, the calves that jump up and run much are very thin.
