Think about it, the last place you would want a false sense of accomplishment is right before you have to jump for real. Using a crossbar instead of a bungee in warm ups might also save the vaulter from a "no height".
I'm going to have to dissagree. I think the last place you want a false sense of accomplishment is right before you swing on a pole you arent going to make pit on, because you dont have a solid reference point in the air. Using a bungee could save a vaulters life, and i think that outwieghs having to use a crossbar to save from a "NH".
I believe vaulters need to take jumps without worrying about hieght in warm ups, only hitting positions. If you have to worry about hitting a bungee, you are way to scared to be a pole vaulter. But there is a legitimate reason for not wanting a bar up during warm ups, if you come down on it or straddle it, it will NOT feel good, and you will start thinking about the bar and not hitting positions. Once the competition comes around, you still just worry about hitting positions, but you need the warm ups to figure it out before the bar goe up. It also takes at least 30 seconds per athlete to put a bar up after they knock it down, inevitably in warm ups. If there are 20 athletes in a meet you are waiting and extra 5-10 minutes PER JUMP just for warm ups. You only have to put a bungee up once.
I've jumped 16'10" with a crossbar and never gotten over a bungee higher than 16' in practice... i dont believe in the 2' rule of thumb. 16' is 16' whether its a bar, bungee, barbed wire, whatever.
