A pleasure to burn: Why do people like spicy foods?

Humans are the only animals known to willingly eat foods that cause irritation, discomfort, and even pain.Theories for why range from thrill-seeking behavior to an evolutionary adaptation for seeking foods that reduce pathogens.Taste results from an interplay of genes, culture, memory, and personality, a complex design that scientists are only now beginning to understand. None If a Martian anthropologist found its way to a Clifton Chili Club Chili Eating Contest, it would discover one the univer...

Cushioned shoes aren't good for your feet

A new study from Helsinki found that the more you cushion your feet, the more likely you'll get injured. This follows previous studies showing that cushioned shoes leave you more susceptible to pain and injury. A few million years of evolutionary design has been usurped by shoe marketing campaigns. None A lot happened to our feet in the transition from being quadrupeds to exclusively bipedal. While the upright organization of our limbs and organs resulted in many benefits in our communication s...

T. Rex Couldn't Sprint But It Could Still Move Faster Than You

Films like Jurassic Park have led us to believe that Tyrannosaurus rex was capable of chasing down its prey at full tilt. New research done with simulations suggest this dino was no sprinter, and that it couldn’t move any faster than a brisk walk. Well, a brisk walk for a nine ton carnivore. At a top speed of 12 miles…Read more...

G.S. George Gymnastics articles

An archive of newsletter articles by Dr. Gerald George can be found here. A sample — “The Mechanics of Impact“: … The effectiveness of the take-off sets the uppermost limits of what the gymnast can hope to obtain during the airborne phase of any skill. During this moment, the path (trajectory) followed by the performer’s center of gravity, as well as the quantity of rotary motion (angular momentum) available for skill execution, are irrevocably established. … Once the gun has been fired, there...

Gymnastics – safest landing positions

Dr. Dave Tilley is concerned: … the unfortunate reality is that the typical way gymnasts were taught to land growing up (me included) may not be the safest for them and most effective to stick skills. Not to mention coaches are also unfortunately very mis-informed about what the best available science suggests for proper landing mechanics. The concerning typical landing position that we need to move away from is one of • Knees and feet together • Glutes engage with the “hips tucked under” into h...

Understanding the Mechanics of Fatigue

When we think of fatigue, we generally think of burning muscles, lactic acid building up, and several other descriptors that have rightly or wrongly entered the lingo of endurance athletes and coaches over the years. In essence though, fatigue is all about slowing down, or preventing that from happening. From a coaching standpoint we often think of the physiologic items that either cause this slow down or prevent it. Traditional coaches might think of increases in VO2max, HR, or acidic condition...

What do Orthotics and shoes actually do? Looking at data from a professional runner

Often times in research we focus on norms.  We look at the average effect of different interventions and then apply them to everybody.  In this way, as a whole we get what the effects are for most people.  By doing this, sometimes we miss the individual effects.  So in today’s first blog of 2013, I want to share with you some data on the effects of running shoes on data with one  individual athlete, Jackie Areson, who runs professionally for Nike. In this data, what we did was stick her on a tre...

The most important information you will ever read about Running Form: Passive vs. Active

I’ve been hanging onto this post for a while now, as I wrote most of it a couple months ago for a coaching friend.  It seemed like a relevent topic and a good enough time to post it here for the rest of you. It might seem like I’m being overly dramatic with the title, but the following two concepts are critical for understanding running form, or even human movement in general.  With the rise in popularity of running form and the increase in running form guru’s that accompanies that, I it was a g...

180 isn’t a magic number- Stride Rate and what it means

Speed= Stride Rate X Stride length It’s simple. It warrants repeating. Through in Ground contact in and you’ve got a nice model….But I digress… There have been a recent surge in articles and blogs in regards to stride rate. It seemed to start with Jay Dicharry’s blog on stride rate and impact forces. Which led to Amby Burfoot and others to join in on the foray. This post isn’t to address that particularly point, but rather a different one that Alex over at Sweat Science brought up in a recent bl...

How to Run: Running with proper biomechanics

The simple question of how do you run is largely unanswered in the running community. You have a bunch of pseudo-guru styles like Pose or Chi, but the key to running correctly to maximize performance is a topic that is largely left to elite coaches or biomechanics experts. As Pete Larson pointed out in his blog, elite coaches like Alberto Salazar extol the benefits of working on running form, but no one has told the masses how. In the following article, it’s my goal to unmask the “secrets” and p...

To change or not: Salazar, Ritzenhein, and running form changes

Ritz and his new form: There is a lot of buzz going around about Dathan Ritzenhein and his form changes. You either fall into one of two camps as Amby Burfoot stated in his blog on the subject: it’s great or insane (his article is here). I’ve got to observe Salazar working on mechanics twice. I was fortunate enough to watch Salazar work on running mechanics with none other than Paula Radcliffe and Kara Goucher when I was up in Portland for the Nike HS Cross Country Champs last fall with Ryan.
