| In professional wrestling terms, a wrestler "blows up" when he runs out
of stamina. This is obviously a very bad thing. It can happen
when someone gets flat-out tired, or more commonly when they overexert
themselves--doing too many big moves in a short amount of time.
The opponent usually has to cover for the blown wrestler, since it's
nearly impossible to do any complicated moves when you're huffing and puffing all over the place. In particularly bad
situations, you can even notice one wrestler literally dragging another
through the match.
This obviously occurs most often to bigger and out of shape wrestlers,
but some wrestlers who look fit enough simply have low endurance.
Most notably, Chris Jericho is known as being sloppy at times and has
sometimes blown up just five minutes into a match.
Some of this is just a sign of the times, as they say. Back
in the '70s and early '80s, it was common for matches to go 30-45 minutes--sometimes
even a full hour. You can look at many classic Ric Flair and Ricky
Steamboat matches, among many others, to see some quick evidence of that.
Nowadays, however, the format of a wrestling show has been adapted to meet
TV requirements--since commercials have to air four times an hour, almost
no match will go longer than ten minutes. As a result, when wrestlers
are called upon to do longer matches for Pay-Per-Views and other special
cards, they're not used to it and don't have the stamina reserves they
used to.
But, some guys are just old and fat and can't work. |
