Big Ten Outdoor Championships winning jump at 2.20M (7'2.5").  Even at that height you can see I struggle with rotation over the bar.  In that still shot I would love to see my head about 4-6 inches lower.  I believe the main source of my under-rotation in all of my jumps is caused by the huge counter-rotary force produced by my lead leg being long and extended during the take-off.  It is the nemesis of a power-flopper.

Badger Track Classic in January of 1996.  Some good jumpers getting some early season competition in.  Nobody is in great jumping shape at this point.  Everybody is training to peak in the June/July timeframe.  Top 4 jumpers were Tyler McCormick, Jeremy Fischer, Ken Hoffman, and Matt Burns.

Practice jumps from 1994.  The practices span several days.  It's hard to say what I was working on.  By this point in my career I was really trying to practice quickness on the final steps and holding the knee all the way to the bar on the takeoff.  I think the latter is obvious in the video.  Generating speed/quickness was always a challenge in my jumping.  I don't think my body was/is wired to be overly quick off of the ground.  I am a power flopper (flop II), but remember that even a power flopper needs speed.

Sometimes the best jumpers in the world aren't necessarily the best examples of how an athlete should high jump.  Recently though, the two most dominate jumpers in the world are actually great technicians of the sport as well and serve as excellent examples on how a jump should be performed.

Blanka Vlasic jumping 2.05M (6' 8 3/4").  She is a technically perfect jumper.  Great slow to fast acceleration on the run-up.  Her lean away from the bar (toward the center of the circle on her turn) is great, which results in very good rotation over the bar.  She drives her lead knee all the way to the bar without any extension/straightening.  Also notice there is no wild jerky layout on top of the bar.  It is one fluid motion, as it should be.

Stephan Holm in an amazing video that covers some of his training and jumping technique.  It's in German, but I could watch it all day even though I understand very little.  My absolute favorite part is from 6:34 to 7:35 where the coach demonstrates the rotation over the bar.  The visual comparison between the rotation of a stick and the rotation of Holm is stunning and proves the point that all rotations are created on the ground.  The athlete, just as a stick, creates nothing after leaving the ground.
