Off the top of my head, no. The muscles body builders develop are fast twitch muscles. Comparing male body builders to female body builders I would intuitive guess males have more fast twitch muscles. However, I can't definitively state males have an increased percentage of fast twitch fibers, an increased absolute number of fast twitch fibers, or the difference is a result of increased muscular hypertrophy. Hormone replacement therapy will definitely affect that. Google J.K. Simmons. At 61 years of age that dude is on testosterone replacement therapy, HGH, or both.
I don't understand the neuro aspect of your question.
