which is probably not that clever. they do highly specific strength work (pulling heavy tires while sprinting for example) and plyometric stuff (mihai's leg program and the like) which is very hard on the passive structures of the body and in all other sports requires - at least according to soviet and eastern germany methodology - to get strong using weights beforehand to support those structures from all the pounding. you get strong, then you start the highly specific explosive and strength work. coaches here say: build a base, then build the house. good on the men to include weight work.
you do not get bigger using weights if you know how to do it. look at the sprinters and jumpers in track: mass is bad there, because this is extra weight the athlete has to carry around. still lots of weight room for them, but no bulk. at all. (excessive bulk going with very little body fat is usually due to steroid use. after some years in the game you know it if you see it.) just lean, fucntional bodies, just like the female american gymnasts.
