Low force x less ground contact time = greater impulse. the guy that is running faster is spending less time on the ground than the slower kid. Same overall tempo but way different impulse created. Focus on running mechanics and doing anything in your power to have a solid cyclical action of your l...

Your comment of the vertical application of force is just false A study done by Peter Weyand states "Faster top running speeds are acheived with greater ground forces not more rapid leg movements" which was published in the journal of applied physiology if you want to check that out. What he says i...

What I am writing is what The USATF (do you know what that is) coaching staff is teaching. Maybe it stands for USA Track & Field. And it is the National Governing Body for track and field (oh yes, this includes race walking). Anyways, my ideas behind the focus on sprinting being with pushing of...

During drive or acceleration it is about power because you have to overcome inertia by performing more or a driving action. ONce you near top end speed it is about conserving energy. There is no driving motion. It is a clawing or pawing action in an attempt to tap your foot on the ground. The less ...

Thank you altius for beating a dead horse. We have all said that you do claw the ground when you run...no one has denied this statement, not even me. What I and one other person have been saying is that your power does not come from that clawing motion. Everything you have said is correct in terms o...

I watched your video. I will agree they hit the ground at the same time. But watch it again very carefully. Which person breaks contact with the ground sooner. As it progresses the guy who is running faster speeds less time on the ground. By the last step shown it is almost 2 frames or more which i...

If done properly the deadlift is designed to work your hamstring and gluteus not your quads. Not true. The deadlift is the most complete lower body lift you can do (even better than squats). It works your hams, quads and gluts with emphasis on the latter two. Therefore, the muscles used to apply fo...

Watching a clip of bubka on http://www.stabhoch.com/ only confirms what I've been saying all along. For any running activity your foot hits out in front of your C.M. and you do claw at the ground to continue forward movement. This is no different in pole vaulting. The thing that nobody is getting is...

For PoleVaulter what I was saying before is that a vaulter doesn't get to the same position as a sprinter is in at 60-70m, which is where the information about horizontal and vertical forces applied is usually taken What you wrote is simply not true. The studies have all been taken for constant spee...

Holding the pole verticle has nothing to do with the position your trunk and legs are in. The picture of dragilla is most likely in her first few steps and as she continues down the runway she will become more upright but she will never rely on clawing the ground. Nobody who runs should. The force y...

well here's a picture of your beloved Yelena Isinbayeva (I'll find one of bubka later). http://gblx.cache.el-mundo.net/elmundodeporte/especiales/2005/03/atletismo/zonamixta/isinbayeva.jpg Anyways, she even has a slight forward lean, but the one thing you should notice is that her foot has yet to hit...

i.e. after the start, drive phase and transition, and so the sprinter is just maintaining their speed and slowing as little as possible, for top sprinters this will be after about 60-70m. My point is that I don't think a vaulter could, or should ever get into this situation. The only way sprinter c...
