This summer I reviewed the research on walking and joint
pain. The findings will surprise you.
Here's what I found.
1) Barefoot walking produces significantly lower knee
forces and torques than walking in any kind of shoe! Even high-tech walking
shoes.
2) Only one type of shoe produces equivalent forces and
torques to barefoot walking: Shoes that are ultra light weight and flat.
3) Any kind of ultra light weight and flat shoe produces
the same result. High tech materials are not required. The requirement is ultra
light weight and flat.
4) Barefoot walking results in zero to 5 degrees of
plantarflexion when the foot strikes the ground. This is called a forefoot
strike. The heel is slightly elevated when contact is made with the ground.
There is no heel strike.
5) Barefoot walking is less efficient than heel-strike
walking. This is actually a good result. It means you will burn ''more"
calories if you perform barefoot walking.
If you put all of these
findings together here's what you can conclude:
1) If you switch from heel-strike walking to forefoot
walking you will reduce joint pain and burn more calories.
2) Wearing any kind of ultra-light and flat shoe produces
similar results to barefoot walking.
I've been forefoot walking
since July. Here is what I can tell you.
1) I am experiencing less knee pain & low back pain.
2) Forefoot walking must be practiced (a lot). If I don't
concentrate on the forefoot landing, I immediately go back to a heel-strike
landing. But, after 3 months it's getting easier!
3) Forefoot walking is ''not" toe walking. Your heel
should only be slightly elevated when your foot makes contact with the ground.
4) Forefoot walking feels really, really awkward.
5) When I started forefoot walking, my calf muscles
(gastrocnemius and soleus) really ached. I think this contributes to the extra
energy expenditure (i.e., burn more calories).
Have you seen any studies that compare oxygen consumption of forefoot walking and heel-strike walking? Is there a statistically significant difference between the two?
ReplyDeleteI just posted an outline of the relevant research related to forefoot walking. The last article in the outline addresses oxygen consumption differences and the possible reasons for the difference. Check it out.
