Those are some pretty big shoes!

This gentleman actually looks like he has acromegaly. Watch his movements and note his facial features throughout the video.

Acromegaly is a condition where excess growth hormone is produced after puberty and the bones steadily increase in girth. Abraham Lincoln was thought to be a acromegalic.

Everything gait. we are…The Gait Guys

Liquid Mountaineering.

Yup, we thought we had seen it all…And they appear to be serious about this. It takes all kinds to make the world go around, but who are we to judge.  It is our guess that that lake was pretty shallow for those first 10 steps or so.  You be the judge.  Even Wallace Spearman Jr. could not reproduce this feat on Mythbusters (until they made an underwater floating bridge !).

Have a good Friday!

Oxygen cost of running barefoot vs. running Shod.

This study concluded that at 70% of vVO (2)max pace, barefoot running is more economical than running shod, both overground and on a treadmill.  So, if you have a competent enough foot to run barefoot or in minimalistic footwear, and it is important to note that some people are not purely from an anatomical perspective, you can improve your economy of running and use your energy sources efficiently. But if you are one of those unfortunate ones that has excessive pronation or other functional foot challenges, you will have to settle for the less economical shod running.  That does not mean you will not have as good a workout, it just means that you will be protecting your foot doing so.  Sure, you might not be the fastest one on the track, but you will be able to show up every day having not compromised  your feet.

Abstract

The purpose of this study was to investigate the oxygen cost of running barefoot vs. running shod on the treadmill as well as overground. 10 healthy recreational runners, 5 male and 5 female, whose mean age was 23.8±3.39 volunteered to participate in the study. Subjects participated in 4 experimental conditions: 1) barefoot on treadmill, 2) shod on treadmill, 3) barefoot overground, and 4) shod overground. For each condition, subjects ran for 6 min at 70% vVO (2)max pace while VO (2), heart rate (HR), and rating of perceived exertion (RPE) were assessed. A 2 × 2 (shoe condition x surface) repeated measures ANOVA revealed that running with shoes showed significantly higher VO (2) values on both the treadmill and the overground track (p<0.05). HR and RPE were significantly higher in the shod condition as well (p<0.02 and p<0.01, respectively). For the overground and treadmill conditions, recorded VO (2) while running shod was 5.7% and 2.0% higher than running barefoot. It was concluded that at 70% of vVO (2)max pace, barefoot running is more economical than running shod, both overground and on a treadmill.

In this Neuromechanics weekly, Dr Waerlop Introduces the cerebellum and talks about its importance clinically, since it contains more than 1/2 of the neurons in the brain! It’s anatomy and inputs from the periphery are discussed. The take home message is the cerebellum is the key to understanding and directing movement, since it receives feedback from most ascending and descending pathways.

Effects of children’s shoes on their gait.

“Shoes affect the gait of children. With shoes, children walk faster by taking longer steps with greater ankle and knee motion and increased tibialis anterior activity. Shoes reduce foot motion and increase the support phases of the gait cycle. During running, shoes reduce swing phase leg speed, attenuate some shock and encourage a rearfoot strike pattern. The long-term effect of these changes on growth and development are currently unknown. The impact of footwear on gait should be considered when assessing the paediatric patient and evaluating the effect of shoe or in-shoe interventions.” -Study

What The Gait Guys have to say…… First of all, we are in line with this studies findings.

To get started with some hard and simple research facts, current research has been conducted showing that plantar (bottom of the foot) sensory feedback plays a central role in safe and effective locomotion, that more shoe cushioning can lead to higher impact forces on the joints and higher risk of injury, that unshod (without shoes) lowers contact time , that there are higher braking and pushing impulses in shod versus unshod, that unshod presents a reduction of impact peak force that would reduce the high mechanical stress that occurs during repetitive events and that the unshod foot induces a neural-mechanical adaptation which could enhance the storage and restitution of elastic energy at ankle extensor level. These are only some of the research findings but they are some of the more significant ones.  Bottom line, shoes can be a problem. Give a shoe that has the minimal amount of necessary support (if the foot needs come pronatory control) and the maximal amount of ability to allow the child to “feel” the ground.  A shoe with a thick cushioned or stiff sole must be like, one might assume, what the foot senses in a diabetic peripheral neuropathy.  Why would we want to numb our child’s attention to the surfaces they are on, Especially with the broad spectrum of neuroreceptors in the foot ?
