Post:


I question whether it's true that their center
of mass passes under the bar. If you look at that footage of Dick
Fosbury going over the bar, and even his competitors using the old
technique, you can see that there is never that much of their bodies
below the bar as they are going over it. By the time their torsos
begin to drop below the bar, they are well past the bar. Is there
some actual proof that their center of mass passes under the
bar?

Hi All,
A colleague and I were looking for some footage of the Fosbury flop (I
hope we have that name right!) which is a way that pole vaulters can pass
over a high bar yet their center of mass passes under the bar. Has
anyone out there seen such footage? Any leads on how I could get a
copy? We've done a bit of web searchign with no luck.
Thanks - Joyce
