It’s not da shoes. Could it be da feet?
Quads, hamies, calves, gluteus maximus. These are the areas you’re told over and over again to train. The prime movers. Where all the power is generated. No dispute there. Get them as strong as you possibly can.
Now lets think about this for a minute. Where does the energy generated by the quads or any of the larger muscles actually go?
Eventually it gets applied against the ground in order to propel you upward.
Check. So far so good.
But how does it get there?
Does it fly magically out into the air and then down to the ground?
No. It travels down your leg, through your feet and only then is it applied to
the ground creating enough force to hopefully send you into the atmosphere.
Muscles and bones act together to form levers. A lever is a rigid rod (usually a length of bone) that turns about a pivot (usually a joint). Levers can be used so that a small force can move a much bigger force. This is called mechanical advantage.
So the final lever in this sequence before all of your force is released is the ankle/foot. Are you with me?
Now what happens to some of that force if your
ankle & foot aren’t strong enough to transfer most or all of it against the
ground? Yep… It’s lost. Just like when your core is week and you go to plant
from a running approach to launch into a jump, a certain amount of your energy
(force = mass x velocity/time) will be lost because a week core can’t stabilize well
enough to transfer all of your forward momentum upward.
A chain is only as strong as it’s weakest link.
Because the ankle & foot get very little training focus, it makes sense that this could easily be the weakest link in the power chain as you attempt to improve your vertical and jump higher.
So how do we strengthen the ankles & feet?
First of all take a look at the shoes you’re wearing. Huge padded heel, arch
support etc… They’re protecting your feet well. A little too well. Your shoes are actually making your feet weaker. That’s right. And on top of that they are the main cause of running related injuries because they promote landing on your heel which sends a shock wave up your knee and skeletal system instead of letting your muscles act as shock absorbers When you land on the pad or ball of the foot. To test this just run barefoot for about 20 seconds. You will notice you automatically will use proper running (shock absorbing) form because if you don’t you will have heel pain immediately.
In addition, an arch is structurally designed to get stronger as you push down on it. When you apply pressure from underneath the arch (arch support in shoes) you actually weaken it.
So now that we know shoes are actually hurting & not helping in the effort to gain ankle and foot strength what can you do?
Bingo… Take them off.
Not during the game, practice or when you go out to eat (cuz they wont let you
in the restaurant and you’ll starve to death) but just enough to allow your feet
to start regaining their natural strength they had before Nike decided to start
the multi billion dollar shoe wars a few decades ago.
Activities for natural ankle/foot strength – perform these barefoot!
Walking & running.
Ankle hops.
Weight lifting – work up to heavy lifting gradually.
Jumping – make sure you have a semi soft area to Land on.
Calf raise or toe raises.
Single leg hops.
Active foot release ie.. Foam rolling the feet.
