The brouhaha surrounding transgender women (male-to-female) competing in women’s sports has only grown louder in recent years for obvious reasons.

Whether it’s Fallon Fox trouncing Tamikka Brents in MMA, Mary Gregory crushing her competition in women’s powerlifting, or Rachel McKinnon sailing away from other cyclists to set a new sprint world record, transgender women seem unbeatable. 

And with the (now delayed) 2020 Tokyo Olympics on the horizon, many female competitors are asking the obvious question: is this fair? 

Transgender women, like Fox, Gregory, and McKinnon insist their past life as a man gives them no real advantage over their female counterparts. Some, like Fox, even claim they’re at a disadvantage

Who’s right? 

I invited Dr. Greg Brown onto the podcast to help explain what science has to say on the matter. 

He’s a professor of Exercise Science at the University of Nebraska Kearney who recently wrote an “expert declaration” on this very subject that examines all of the relevant research currently available.

In this interview, Dr. Brown breaks it all down, explaining the physical advantages men enjoy over women, how they affect sports performance, and how many of these advantages remain after a male-to-female transition.

Press play and tune in!
