Greater Ground Forces

Expert Discussion Biomechanics and Physiology
1

I know this was discussed here before but not many touched on this subject.

But what are some ways to develop great ground forces w/ each foot strike? While keeping the Ground Contact time low?

I feel this is the main area to help sprinters shave off .45 off their sprint times, according to Mann and others.

Any ideals on training for this area?

Increase strength without increasing bodyweight? Brilliant! …no shit

Every session, deadlift 2-3sets of 2-3reps at 85%-95%? Gotta be some misinterpretation here.

This guy coaches one awesome girl and all of a sudden he is credited with discovering the “holy grail of sprinting”?

Sorry, I’m in sarcastic mode this morning.

I don’t know man, do you really think increasing ground contact forces is the answer? I would be more concerned about your hip height. This topic was covered in depth before, there were pages and pages. I am not sure where to find it, but read Charlie’s comments on the subject and you will have your answers.

Simplified…
Increase in strength allows you to apply more force to the grounde in a shorter amount of time. For every action there is an equal and opposite reaction so that the more force applied the higher the hip height to may achieve. Higher hip height give you more room for the swing phase in sprinting therefore helping you cut down ground contact time.

Its only one of the answers. Technique is important too. You have to apply great force properly.

I don´t remember where, but, i read some article about a German Lab ( Adidas ?? ) where they have an electronic “track” which can measure the forces generated in each step against that “digital surface”, so, if it is true, imagine how interest could be this equipment for Sprint Analysis.
Let´s call Kim Collins and Asafa Powell now !!

This topic is covered extensively in the forum review.

The other day my coach talked me into doing some triple jumps with a team mate who was preparing for comp. I did them off both legs and I’m really feeling some extra power when I sprint. That stuff makes you generate a lot of power.I’ll continue doing them (with moderation) to see how much I improve
