An interesting slide show about factors affecting sprint performance and how to break those barriers.

Summary of what it says:


* To Increase speed you need to increase power the power your legs produce into the ground in vertical axes in a short amount of time with minimal horizontal forces being applied, the result will be an increase in stride length and stride frequency rather than the old way of thinking that you had to train these things, but these are rather cause of developing power and becoming faster.
* ground reaction force is 3x bw while muscle forces in excess of 7xbw
* Extending acceleration by staying in a pushing mechanics helps with reducing fatigue later in the race, low heel recovery, piston like action of legs and gradual slow progression of the body angle
* Posture, tall hips, trunk upright, head level, posture is very important in developing greater amount of speed
* leg stiffness (this is very important to withstand high levels of tension the body endures during running), its the ability of the leg to act like a spring with energy stored in a coiled up spring,this increase vertical impulse, reduces ground contact time and increases elastic return
* This is quite interesting - stride length is determine by quality of force application during ground contact time, The quality of this force application is related to the degree of stiffness in the supporting leg, as well as the speed of forward flexion of the free leg
* To develop leg stiffness, Eccentric strength work, depth drops and depth jumps, Stiffness jumps, vertical emphasis plyos
