Unser Chat » foot is going to be freed to

I’ve thought a lot about these questions, and have some thoughts on each, but for this post I wanted to concentrate on point number 4. To do this, I solicited the help of Dr. Casey Kerrigan (see photo to the Nike Air Max 270 Hombre left), who has published over 90 peer-reviewed papers on walking and running gait (with a particular interest on the causes of osteoarthritis). Casey has an amazing background and an immense amount of clinical experience – she founded the gait labs at both Harvard and the University of Virginia. Recently, Casey took the amazing and gutsy step of resigning from her tenured faculty position at the University of Virginia so that she could start a shoe company called OESH. She had come to the point in her career where she felt that she could have a more positive impact on the Nike Air Max 90 Womens well-being of her patients by developing a shoe that works rather than by spending her days in the clinic or publishing papers. As a fellow tenured college professor, I can assure you that one does not give up a job like this without great risk (both professional and financial), and I’m incredibly impressed Nike Air Vapormax Womens by willingness to make such a move.For years, I’d been putting together force plate data with 3-D motion analysis data in walking. Combining these data and evaluating them in light of our clinical information (all the problems that came to our general clinic or to our specific runner’s clinic), we could finally understand how and why we get the types of repetitive injuries we do. Remarkably, this had never been done before. You could say that the “a-ha” event of all my best research was synthesizing the force plate data with Nike Air Max 2017 Femme the 3-D motion data—this was the classic 1 + 1 = 3 breakthrough that every researcher hopes to discover. If you’re interested you can read more about all this in my post The Rest of the Story.I first started looking at the forces associated with knee osteoarthritis. But what I found applies to nearly all of the typical injuries we see. The peak forces stressing nearly all the injury sensitive areas of our body Nike Internationalist Femme occur when our foot is fully planted (not at impact) and fully pronated. The specific forces at the moment of impact are miniscule and sometimes in the complete opposite direction to where injuries occur. More critically, the forces across virtually every injury prone area are highest at two points in walking that occur well after impact – when loading weight onto the foot and when lifting the foot off. These injurious Nike Air Force 1 Femme forces peak at one point in running – at midstance, well after the peak impact force.Our findings are quite logical when you think about them – we’re at risk for injuries when we also have to support and transfer our full body weight. But they really do fly in the face of what everyone, (including the athletic shoe industry) has always promoted – that foot impact is what causes the really bad things that happen to bones and joints, such as stress fractures and osteoarthritis. To this, I like to say that the only way a cushioned athletic shoe can protect you from injury is if you are in a car accident and happen to Nike Roshe Run Mujer have them strapped around your head.What is the effect of a traditional running shoe at this critical moment when we’re fully supporting and transferring our body weight and are at risk for nearly every single common running injury, second metatarsal fracture included? The raised cushioned heel and arch support / motion control features that are both inherent to every traditional athletic shoe (not just motion control Adidas Superstar Femme shoes) essentially freeze out the foot’s natural function in providing compliance that helps protect the rest of the body. Also, the cushioning, which doesn’t really give back in any physiologically meaningful Nike Air Max 2017 Dames way, just makes it harder to transfer the body weight, which increases peak joint torques at this critical moment.If you are running barefoot or in minimalist shoes, your foot is going to be freed to provide compliance at this critical moment. We’ve demonstrated that the foot arch compresses and releases in perfect harmony with the rise and fall of the peak body weight force. Of course, that compliance is good – it protects your body north of the foot from all the major injuries at that time. It also healthfully exercises your plantar fascia and foot intrinsic muscles. Good, good, good! But it does put more stress through Nike Air Max 90 Herr the second metatarsal than there ever was before.
