Elitetrack: Sport Training & Conditioning

In the article "Closer Look at the Shape of the High Jump Run-up" by Jesus Dapena, Indiana University, U.S.A. there are some questions I have. http://coachr.org/a_closer_look_at_the_shape.htm

How exactly can I calculate my final approach speed in m/s?

That is a crucial element in the formula to get the radius of the curve (r=v^2/6.8 ).

Also, how can I possibly measure the final direction of the run-up and the final direction of the footprints' path in order to get the distance of value j?

J is necessary to find the center of the curve by making a right triangle. (fig 3)

1.  Burn the Dapena article and any computer used to read it.
2. Run 3 or 5 steps on a straight line, 90 degrees to the Bar.
3. Enter a 5 step curve (not 4 or 6) by slightly turning in the outside foot on the 3rd or 5th straight approach step.
4. Learn how to run on a curve.  Circle runs are great but most often people train on way too small a radius.  Think big circle closer to an indoor tracks curve if run as a complete circle
5.  Stay on the curve, penultimate may vary slightly but dont aspire to this.
6. Plant step on the radius line of the curve please
7. Lastly and most important, stop reading scientific articles meant for maybe 50 coaches on the planet.  A general note to the board would be for all to stop trying to apply Olympic, Gold medal Concepts in cases where the individual is at a lower developmental level.  "More is NOT better"

Yea, I have a habit of making things more difficult than necessary. I need to just KISS (keep it simple stupid) Thanks for the reply though. 

atta boy...  Give um hell.
