The current world record in normal high jump is 2.45 metres, set by Javier Sotomayor in 1993.
I read somewhere that in normal high jump, jumpers must take off on one foot. But if you relax the rules a bit and allow jumping with both feet, I guess it might be possible to jump even higher.
How high is it possible to jump allowing taking off with both feet? Is there any such world record?
I remember watching some international high jump competition in TV a few years ago. The Swedish TV commentator then made a comment about one of the high jumpers, that he almost jumped with both feet. The jumper clearly jumped with one foot, but I guess that by just changing his technique a bit he would jump with both feet. The height of his jump was somewhere around 2.30 metres. I would find it surprising if a two-feet jump would be significantly lower than that.
