Claim #1: Strength is irrelevant
Peak strength is irrelevant because it takes too long to generate when ground reaction forces in sprinting are applied in under 1/10th of a second.
  • One area both camps(pro and against strength work) agree on is the importance of force in creating speed
  • When it comes to speed, force production is critical!
  • It is a well-documented phenomenon that force applied to the ground is a key distinction between elite and sub-elite sprinters
  • Ground reaction forces for elite sprinters can exceed six times bodyweight on ground contact once they reach top speed.
  • For a 170lb sprinter, that’s 1020lbs, or 4,500 Newtons of force!!
  • Many coaches who argue against heavy strength work make the case that since peak strength generally takes .3-.5 seconds to generate in most barbell movements—and these enormous ground reaction forces have to be applied during ground contacts that are less than .1 seconds
  • To use the weight room in the same time constraints as sprinting shows a misunderstanding on strength and speed
  • Raising max strength is to raise your “strength reserve” just like speed with distance running
  • so if my max strength I can achieve in .4 is 300lb then I might be able to achieve 120lb in .1
BUT
If I can achieve 400lb in .3 then I might be able to achieve 200lb in .1 of a second, make sense??
