Quick Running Tip: Try Forefoot Striking

Running injuries are nothing new. In the 1970s, when running injury data was first collected, about 20 percent of runners had injuries, with the top five injuries affecting the knee, Achilles tendon, shins, foot, and ankle. (1) Since the 70s, both the number of runners and their injuries have gone up: Today it is estimated that up to 70 percent of all runners will experience an injury every year (with the top five running injuries found in the foot, Achilles tendon, upper leg, knee, and shins). (2,3) And this increase in injuries is despite of latest running shoes designed to cushion, support, and control runners' feet.

There are lots of possible reasons for all these injuries (e.g., modern shoes, asphalt running surfaces, poor training, popularity), but one surprisingly controversial cause might be how you strike the ground.

A person can initially make contact with the ground while running in one of three different ways: With the hindfoot-, mid-, or forefoot. Hindfoot (or heel) strikers will first land on heel of their foot, while midfoot strikers land with their entire foot. Forefoot strikers will land on the balls of their feet.     
Heel strikers impact the ground with their heel first; midfoot strikers place their whole foot on the ground; and forefoot strikers land on the balls of their feet (and may also lightly make contact with their heel before pushing off).

Although heel striking is popular with today's runners, (4,5) it seems that forefoot striking is a more natural way to contact the ground while jogging and running. You can test this out by trying to run barefoot. No matter what your running style is when you wear shoes, we all run on the balls of our feet when we run barefoot. Heel striking is only possible in modern running shoes.

Rapid PT Food Pyramid: The 7 Deadly Foods (Foods to Avoid)


UPDATED - 27 April 2013: I have updated the list of chemical additives that you should avoid.

This is the first of four posts that describe my Rapid PT Food Pyramid. This pyramid is the synthesis of everything that I've learned over the past four years. It combines perspectives from the Paleo, Primal, and traditional diet philosophies, as well as some of my other investigations (e.g., sports performance, optimal nutrition). Following this generalized diet outline should help you easily maintain a more ideal body weight, enjoy more energy, and possibly eliminate some/most of your current health problems (of course, the diet and lifestyle history of you and your family can limit how much you can reset your health).

My food pyramid is divided into four sections: Avoid, Minimal, Optional, and Foundational. It's basically designed so that the foods found at the bottom of the pyramid (Foundational) are eaten the most; those found at the top (Avoid) are eaten the least.

The Foods You Should AVOID
The Avoid section contains all the foods that you just shouldn't eat if you want to be healthy and fit (except for your cheat meals). It contains seven foods: Wheat, soy, gluten grains, refined sugar, chemical additives, high omega-6 oils, and trans fats. I like to call this group The 7 Deadly Foods because, from an evolutionary point-of-view, they are new to the human diet and (I believe) cause most of the diseases that plague Western societies.

The main reason that I chose these seven foods is because they are associated with the negative consequences of the agricultural, industrial, and green revolutions. I will talk about these consequences in greater detail in a later post.  

Wheat
Originally, when humans were hunter-gatherers, they ate a variety of meats, eggs, vegetables, and fruits. These early diets produced strong, healthy people.

About 10,000 years ago, a few humans in the Fertile Crescent started to cultivate wheat (and other grains), ushering in agriculture. While grains provided a storable form of food, it came at the expense of poor health and disease because it was a food that the human body was unfamiliar with. Although it took a while, grain-eating humans eventually adapted genetically to grains and figured out how to make them more nutritious and less toxic (through fermentation, sprouting, and soaking), allowing human health in these populations to eventually recover.

For thousands of years, human health wasn't too affected by older species of wheat (einkorn, emmer, and durum) because these species of wheat contained little gluten and were properly prepared. Then came the Green Revolution in the 1950s. A higher-yielding dwarf wheat was created to eliminate the many famines experienced at that time. This modern dwarf wheat slowly replaced the wheat traditionally grown and consumed for thousands of years.

Since then, wheat has been further modified to continue to increase its yield and baking qualities. An unfortunate consequence of all this modification was the creation of a wheat that now produces fewer nutrients and more gluten, starch, and lectin. Together, these three ingredients of modern wheat can cause: (1)
  • Autoimmune disease
  • A less robust gut barrier
  • Cancer
  • Chronic pain syndromes
  • Increased appetite and hunger
  • Insulin resistance
  • Gut irritation
  • Leptin resistance
  • Poor nutrient absorption

My New Blog: Mayo's Mind


What started as a simple 10-page diet and exercise program written for a friend struggling to pass his PT test has become the expansive Rapid PT blog (with over 60 posts) that you are reading now. Over the last year and a half, this blog has helped hundreds of people in the Air Force pass their PT test and encourage hundreds more to improve their health by simply changing their diet. And although many of my posts required a lot of exhaustive research, I never really thought of it as work.

But recently I have realized that I have used this blog as a place for me to talk more about disease prevention than passing the PT test. So, to re-focus the Rapid PT blog, I have revived an old blog called Mayo's Mind to talk about less PT-related topics. I will then start writing more posts on this blog that are specifically concerned with improving your push-ups, sit-ups, run times, and waist measurement.

And thanks again for making this blog as popular as it is. As always, if you know someone who is struggling with passing their PT test, please tell them about my 42-day program.

How Leptin Resistance can Cause Obesity


I just posted on my Mayo's Mind blog about how I believe that malfunctioning feedback controls not only cause someone to be overweight, but also cause their brain to actively defend this abnormally heavy bodyweight, producing the familiar yo-yo like effect on bodyweight if they try to consciously restrict their calories (either through eating fewer calories, trying to "burn" off extra stored calories, or both). This could prevent someone from losing weight even if they are technically starving themselves. Check it out!

Lost 14 lbs and 2.5 Inches!

Bryan,

Figured I would drop you a line and say thank you for the information you put on your PT site. I started the program right after Thanksgiving and tested today, so I went a little over the 42 days. I moved to a desk job that allowed me to get lazy. Knowing that my PT test was coming soon I looked to your site for guidance. Well it worked, I dropped 14 pounds and 2.5" off my waist, my run could have been better but it was brutal cold for Mississippi (39 degrees) so I ended with a 13:04 run time (last week in the warm I was pushing 12:30s easy, way better then the 14s I was pushing in November). Sit-ups--I did 50--were a breeze; I could have done my push-ups, but I have profile due to bursitis in my elbow. Either way your "program" worked for me, with some "funky" type modifications. Just figured I would tell you of a success story.

Thanks,

Mike
