im a natural sprinter and i must say it correlates very well with jumping once you got some coordination and a good strength base. i need to work on my run up coz im not properly using my speed. As for kadour, that interview says alot. And id bet that if anyone here trained and jumped for 17 years with kadours sort of enthusiasm, They would have a high vert at there peak.
