Ditch the Shoes? Try These Barefoot Science Tips
Who doesn’t love a sweet pair of sneakers? Not only are they functional but they are fashionable, but sometimes you may need to ditch the Nikes to help improve your mobility. Celebrity podiatrist Dr. Emily Splichal drops by to discuss some barefoot science that will help prevent injury and improve your mobility!
Barefoot science at its finest
For a dancer, athlete, surgeon or pilot – precision of movement is crucial to the success of their career.
Even the slightest deviation in movement accuracy can have devastating ramifications – not just to themselves but also others. Although the demands of the above movements may not apply to all of us, can we still take the concept of movement accuracy and apply it to our everyday lives?
Absolutely!
Movement Accuracy & Overuse Injuries
As a Podiatrist in NYC, I am presented with patients experiencing foot pain such as Achilles tendonitis, plantar fasciitis, and stress fractures – all injuries I associate with poor control of impact forces and inaccuracy in movement patterns.
The inaccuracy in movement patterns I am referencing is in their gait or walking.
As the second most common subconscious activity we do daily (besides breathing) the demands and movement accuracy needed for walking are often taken for granted.
All too often the interaction between foot and ground is not appreciated and is overlooked by most patients.
Potential Energy & Impact Forces
Often referred to as a series of controlled falls, walking should require very little external energy. With each step we take gravity is accelerating our swing leg forward into initial contact or heel strike.
Upon heel contact 1 – 1.5x, our body weight in impact forces enters our body in less than 50 milliseconds. This rapid input of impact forces is designed to be damped or absorbed by the body, stored as potential energy, and released as elastic energy.
Due to the rapid acceleration of impact forces, the only way the body can effectively load this potential energy is if the ground is anticipated. If we wait for the foot to strike the ground to react to the impact forces – it is already too late.
Delayed loading response can lead to movement inaccuracy, compensation patterns and injury.
Movement Anticipation
Movement accuracy is deeply linked to movement anticipation or pre-programmed motor responses set to known movement patterns. Often referred to as feed-forward or pre-activation responses these motor patterns are stored in the cerebellum and are based on past experiences.
One of my favorite researchers on this topic is Dr. Benno Nigg out of the University of Calgary.
Imagine if we were able to walk and be able to anticipate the ground and the impact forces before each heel strike?
How would this impact our injury risk?
If we begin to anticipate the ground we would be able to load impact forces faster and more effectively. In theory, we would be able to improve the accuracy of our movement patterns and reduce our risk of overuse or impact-related injury.
Improving Movement Accuracy
When it comes to improving movement accuracy the biggest concept here is that our movement patterns are only as good as the information we bring into our nervous system.
Bad movement patterns create movement inaccuracy.
When it comes to walking and the loading of impact forces, one of the biggest contributors to movement inaccuracy is our shoes.
With the plantar foot containing thousands of highly sensitive mechanoreceptors, any barrier between the ground and the skin on the bottom of the foot will alter the accuracy of information coming into the nervous system.
The accuracy of impact force rate and intensity will be altered. The accuracy of foot placement and perception of surface compliance will be altered.
Ultimately the risk of injury will be higher.
Enter Barefoot Training
Part of the prescription I give patients every day is to integrate barefoot stimulation into their daily routine.
This may be as simple as a barefoot trigger point release first thing in the morning. Or it may be 5 minutes of barefoot movement prep before a run.
Whatever the technique the benefit of getting out of the shoes and stimulating the nervous system from the ground up cannot be expressed enough. Want to kick it up a notch – these are my favorite barefoot strong tips:
- Plantar foot stimulation – 5 minutes 2x a day and before working out
- Short foot activation – 5 minutes 2x a day and before working out
- Barefoot balance exercises – 5 minutes before working out and 30 minutes 2x a week
