More you say?

How about this study displaying increased myoelectric activity and decreased oxygen saturation in women, indicating the need for more rapid motor unit turnover (less contractile force per MU due do decreased 02 flux, which you already should have known if you really were an MD student):

The relationship between oxygenation and myoelectric activity in the forearm and shoulder muscles of males and females.
Elcadi GH, Forsman M, Crenshaw AG.

Or this one displaying decreased hamstring stiffness in women, leading to compromised ability to resist changes in length due to movement:

Sex comparison of hamstring structural and material properties.
Blackburn JT, Bell DR, Norcross MF, Hudson JD, Kimsey MH.

More conclusively, how about this study showing increased muscle damage in men, leading to a concomitantly increased catabolic (and thus anabolic) response to muscle stress:

Gender-related differences in muscle injury, oxidative stress, and apoptosis.
Kerksick C, Taylor L 4th, Harvey A, Willoughby D.
