Yeah, it's probably a liability thing. My sister was on the Morehead State cheering squad in the late 80s (they always kick butt at competitions), and she ended up having to have big knee surgery because one of the guys dropped her at practice and she ripped a bunch of ligaments. The surgery was expensive and had to be done in a city 3 hours away, and she was on crutches forever. So I can understand why they would want to avoid accidents like that.
BUT...no jumps?!? That's ridiculous. Next thing you know they'll be making you wave paper pompons wearing calf-length skirts, saddle shoes, and sweaters with huge chenille letters on the front.
