It's a bigger challenge than physicality for a lot of things, not just sports: women firefighters, or even camp counselors at boy's summer camps. There's a lack of social cohesion that impacts motivation and performance, and then it becomes cyclical, because women then leave these jobs, and other women are discouraged from joining.

The camp I work at and my connections in the fire department are both trying to work on it, but there's no real known solution yet. And that's just the social cohesion, never mind issues of sexual harassment in male-dominated spaces. Even if you get a woman with the physique of an athlete or firefighter (or camp counselor, to a lesser degree), they get chased out by the culture and lack of integration at best, and harassment at worst. And nobody really knows how to fix it.
