As a physio, I see a lot of running-related injury, dysfunction, and performance loss. Depending on who you read, injury incidence among runners can be as high as 85% many of which are due to training errors and poor mechanics. In that vein, this week's post is from Jeff Ford, a CrossFit Endurance and USA Triathlon Certified Coach, Owner and Founder of Fire Coaching Consulting, and excellent endurance athlete. Great dancer. Drives a nice car.
Foot-strike: Time and time again, I watch runners on the street and I just want to pull over. A large majority of the endurance athletes I get on tape are landing out-front and breaking themselves while landing on their heels as they chronically over-stride (increasing peak forces on the body). Your heel was not meant to land first guys. Trust me. Take your shoes off and have someone video-tape you running. Your body physically will not let you heel strike. It wasn’t meant to. When you strike heel first, you land primarily on bone and lose the ability to harness muscle elasticity in your foot/ankle complex. What that means in KISS (Keep It Simple Stupid) terms is that you’ve lost the ability to absorb your weight as you land. You’ve shut down your muscles ability to stretch and contract when force is applied. Not good at all, especially as the distance gets greater. So fall from your ankles, don't smash thru them. Seth and I recommend a consult prior to switching strike patterns as this is a daunting task on your own.
