Ok kids, here’s the truth…
Forget about “midfoot, forefoot, heelstrike” and run natural. Threre is no wrong form when running barefoot.
“top” runners will strike on the heel when running at a fast, even pace. That is because the most energy efficient way for the human foot to move is heel-toe. We are not always trying to be energy efficient like in a 800m race or durring the kick of a 10000. we are going for fastest possible, not economy of energy.
I have seen WR runners at SUB 4:10 pace striking on the heel, barefoot! Anyone who tells you that you cant strike on the heel while running barefoot has not looked at the whole picture. The strike will change continously durring any given run but the body, like all things in nature, will ALWAYS return to the most energy efficient motion unless asked to do otherwise (like in a kick or durring a surge in pace)
FORGET ABOUT THE STRIKE! its all about running natural. Cushy running shoes do interfear with the feedback that the body gets from the ground and dulls the impact so the body will try to become MORE energy efficient by OVERSTRIDING and striking the heel too hard. This is not always a good thing.
The most gifted runners will strike the ground with up to 2 times their body weight and toe off with up to SEVEN TIMES their body weight. They have learded to minimize the waisted energy (absorbing the strike) and maximise their own muscle power (creating energy rather than absorbing it) which is far easier on the body. Most specialists will tell you that we strike with up to 4 times our body weight. That is from running in too much shoe. AT MOST we need the cushioning from a good racing flat but only for running on hard surfaces. Even then, its not really needed, depending on the volume and intensity of the training.
The best thing that you can do for your form is to run barefoot. As I said before, there is no wrong form when running barefoot. If you want to improve your skill as a runner do ALL of your running barefoot for a few weeks. Go to the track, find some grass, use a treadmill or tough it out on the sidewalks. Grass or the track is best. After two weeks break out your favorite racing flats and resume regular training making sure that your cadence is above 180 no matter what the speed. If you can run slow (1.5-2 min per mile below aerobic conditioning pace) at 180 you are well on your way to good running form.
As far as the back kick, forget about it. only at very high speeds can we really utilize the shorter lever of a high back kick. For that matter, its not really a “kick” but themost effecient way of returning the foot to the ground after a powerful stride that leaves the foot a higher off the ground after toe off. Its not forced at all, ti just comes with running very fast.
I’m going back to work. I wont even bother to spell check this crap.
