Actually, most of the hockey and rugby teams I worked with were women. Yes, women tend to have higher body fat % than men, even when they’re high level athletes.
Frankly (WAG), I would think that (as long as they can pass the fitness requirements) a little extra weight might be a good thing for a female firefighter. One article earlier in the thread said this recruit had difficulty handling a hose, and that the force of the water almost (did?) knock her off her feet on at least one occasion. If you have a little more body mass then you have more inertia and it would be harder to be knocked down. They’d also be able to exert more force when doing something like knocking down a door.
By the way, searching for an example of female rugby players I looked on the Canadian National Team website - the player heights and weights listed seem similar to what I recall from university level players. Of course, players in certain positions seem to have certain body types, just like in football.
The recruit was 5’4" (160cm) and 190lbs (86kg). Her weight is comparable to several players on this rugby team (and some are heavier), although she is about 10-15cm shorter than most of the players listed below.
Examples from the womens rugby team:
180cm, 85kg
178cm, 90kg
173cm, 87kg
(no height listed), 93kg
178cm, 86kg
175cm, 95kg
168cm, 84kg
178cm, 98kg
