Wichita Shootout Roller Derby - KC vs Texas Roller Girls

No. If they kept going the girls would wear out and the game would become too predictable and less strategic. Besides, they regroup pretty fast between jams and the jammer as well as all the other girls change every jam. And they rarely stop the clock. It still goes fast.

No, they wouldn't "wear out" the girls by having them stop the jam. The girls would just need to pace themselves better. I mean in hockey the guys can easily skate around the rink for long periods of time, so I don't think that is the factor. I think the real reason why they do it is so one team doesn't get a huge lead by having a jammer mess up early on. Still, the sport could be improved I think.

It's really a strategic move to keep the other team from scoring.If you're lead jammer, you can rack up a few points, then call it off before the other team gets a chance to score.

Even if the jam weren't called off by the lead jammer, the maximum length for a jam is 2 minutes.
