And, below is a detailed outline of podcast #3.

1. NEWS  OF THE DAY:

Hello:  I recently saw you guys speak at the NSCA clinic at Chicago State University and I am immensely impressed and relieved to find someone able to clearly explain gait in such thorough detail. The Gait Guys blog has been immensely helpful in myself and my running clients. I would like to inquire if “either of you” would be interested in being a guest speaker at the AMA as a part of our Wellness Program’s monthly seminar series.

2. TOPIC:

 Computer simulation of stress distribution in the metatarsals at different inversion landing angles using the finite element method

 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2903174/

Abstract:  Metatarsal fracture is one of the most common foot injuries and is often associated with landing in inversion. The deformation and stresses of the metatarsals during landing at different inversion angles (normal landing, 10 degree inversion and 20 degree inversion angles) were comparatively studied. The results showed that in the lateral metatarsals stress increased while in the medial metatarsals stress decreased with the angle of inversion. The peak stress point was found to be near the proximal part of the fifth metatarsal, which corresponds with reported clinical observations of metatarsal injuries.Landing in inversion is another factor which potentially could affect the metatarsals leading to deformation and fractures; however, most published studies on landing in inversion have focussed on ankle ligaments and sprains during this abnormal movement

3. TOPIC:

Pencil Skirts: walking in one and how it is troublesome for normal gait

4. EMAIL FROM A COACH:

*( we will be answering most of your questions on these podcasts. It may take a week or 2-3 to get to them. We hope to have a “podcast table of contents for each podcast” on our new website when it gets launched. That way you can search for topic lists and look for your email. We will only use your first name, or whatever name you wish to provide. We will not give out your email. 

 \5. YOUTUBE AUDIO CLIP:

The body’s biomechanics are different running up and down hill,  but you are also dealing with gravity differently.

  Einstein did these things called “Thought experiments”.
 It is a YOUTUBE CLIP , type “albert einstein-2"  into the SEARCH box.
we will start the clip at 4:14 min clip  to 8:40

6. REVIEW of our favorite BLOG POST OF THE WEEK:

The Secrets to Running Downhill Fast.Last month we contributed to Jene Shaw’s article in Triathlete Magazine.

Please hit the link here for the entire great article by Jene Shaw. There is lots more here. LINK

Here were some of our Form tips used in Jene’s article for going fast downhill. Hear about them on the podcast.

7. EMAIL CASE
Hi there
I’ve been going to physio therapists for a while with lower back and posture problems, which I now think are related to how I walk (duck footed). So far the only thing I have really got from this would be a nice massage.
What is the main issue with the "Duck footed” posturing and what kind of professional or practioner should I see about correcting issues like this?
Thanks very much, MIKE

8. SHOE TALK:

The vivobarefoot

9. EMAIL CASE

Hello Gait Guys,

In the past, I have sprained my left ankle in which has led me to think that this is the cause for me having a flat foot.

This in turn has led me to having problems around the knee and the hip.

Are there any exercises I can do to improve my medial arch? 

If there are videos that you are selling to teach how to deal with this problem, could you link me to it?

Sincerely, Zac

response:   youtube video:  The foot tripod: the importance of the toe extensors in raising the arch.  also read our blog post ( February 16th, 2012 blog post for more)

10. EMAIL CASE:

Hi There,

My name is Damien and i am writing you from Ireland. I’ve watched a lot of your videos online on YouTube. They are amazing. Congratulations on such a great and informative service. It’s so refreshing seeing people want to diagnose and fix feet rather than putting insoles or arch supports in place. I have alot of things going on with my body, let me get started … . .

So that is the topic list for this week, podcast 3. We hope you can find time to lend  us your ears.

Gait Pathomechanics: Walking in a Pencil Skirt.

If you want more on this topic, Drs Allen and Waerlop go on a fun and informative rant on fashion, pencil skirts and high heeled shoes on Podcast # S1-E3 (Season1-Episode3), a soon to be released podcast episode.

Who knows why this video is even on Youtube. It is 6 minutes of this gal walking back and forth, so do not watch  more than the first 60 seconds for anything exciting, trust us.  Read the blog post and then come back to the video and see what we talk about. There are some severe gait compromises in a skirt like this, let alone with the high heel shoes accompanying the gait.

According to wikipedia:
The slim, narrow shape of a pencil skirt can restrict the movement of the wearer so pencil skirts often have a slit at the back, or less commonly at the sides. Sometimes a pleat, which exposes less skin, is used instead of a slit. The classic shoes for wearing with a pencil skirt are high heels,^[3] with sheer stockings or tights. The predecessor to the pencil skirt is the hobble skirt, a pre-WWI fad inspired by the Russian Ballet. This full-length skirt with a narrow hem seriously impeded walking. The French designer Christian Dior introduced the classic modern pencil skirt in the late 1940s. The pencil skirt feels different from looser skirts, and can take some adjustment by the wearer in terms of movement and posture in order to manage it successfully. Walking needs to be done in short strides; entering and leaving a car gracefully takes practice; and when sitting the legs are held close together which some find restrictive (though others like the feeling of their legs being “hugged” by the skirt). Activities such as climbing ladders and riding bicycles can be very difficult in a pencil skirt. The pencil skirt is warmer due to the reduced ventilation, and is less likely to be blown up by gusts of wind.

The Gait Guys dialogue on pencil skirts :
Tie a rope or theraband around your knees, you will suddenly experience the short cute steps that this gals does devoid of almost all hip flexion and hip extension, both serious gait cycle restrictions.
Without hip flexion-extension the entire timing of the swing phase is off. No longer can there be adequate use of the obliquity of the pelvis and thus abdominals or contralateral leg swing to initiate supination and toe off.
Step and stride lengths are dictated by the tightness of the roap, and in this case the diameter and give of the bottom of the skirt.  Not to mention the bloody complication added by the high heels !
- There is an unnatural oscillation of the pelvis due to the restrictions mentioned above.

The Pencil skirt:  Never again will you be able to wear one and not notice its gait impairments. Nor will men be able to just watch the ladies in the skirts for the appreciation of beauty and style. Men, you will have much more to study now, you just may hate us for your undying need to evaluate the biomechanics in skirt wearers forevermore ! Just be sure you do not abuse this new evaluation superpower as an excuse to your spouse to watch girls walk by.  We are not responsible for abuses of acquired superpowers.  And although we many have actually just become your new heros, just remember, with great powers come great responsibilities.

Once the website launches you will find our new product, “pencil skirt training noose” on our online store.  $50 for the finest of roap loops ! 

There is so much more on this topic in Podcast #3 . Be sure not to miss it. We will launch it here on the blog and on our Facebook page and in iTunes once we get permissioned by Apple.

Shawn and Ivo, your new superheros of gait. Gait Fashonistas, perhaps we have a purpose and calling in the fashion industry !
