Everything about jumping and sprinting and how to improve your performance
A recent request from a young athlete's dad in the US to analyse his son's long and triple jump technique got me thinking in the process of pulling the video together (see below)... I have a 'combined' jumper in my training group Jonathan Ilori (bests of 16.28m and 7.32m) and his long jump - although good - suffers from a too long last stride. He tends to reach into the take-off and lower and lever into the air. Strangely enough his hitch-hang technique after leaving the ground is very good! And, there were some parallels with the American young athlete, based in Iowa. However, he tended to take large steps into the take-off for both the long and the triple. It's imperative for the TJ, to run off the take-off in order to maximise speed through the remaining phases. The angle of take-off is circa 16 degrees and this contrasts with the long jump one which is around 22-degrees. The LJ take-off also requires the athlete to 'set' more on the penultimate step, which will generally be slightly longer than the preceding step and definitely longer than the last step. They'll also be more lowering of the centre of mass by a couple of cm's. I made some suggestions as to how the US-based jumper may improve his take-offs for both horizontal jumps in the linked video (plus other areas of his technique). Perhaps the key one for all dual jumpers reading this - in addition to my previous comments about the angles of take-off etc, for both events - pertains to the length of the last step for both events. The long jump one tends to be around 2.20m and the triple 2.40m for senior men. I suggested that the US jumper work to these distances on his run-ups for the different events to improve his take-offs, Indeed this is something that we have recently been working on with Jonathan (for the TJ). There was a comment on the video about how top US coach Jeremy Fischer perhaps eludes to the idea of using different take-off legs for the hop in the TJ and the LJ - perhaps this is designed to untangle neuromuscular confusion. In time I will look more into this.
