Pronation

It is important to understand pronation and the way your foot moves when you run. Some people pronate more or less when they run. Learn about normal pronation, overpronation and underpronation, and how you can prevent injuries in this article published on Runnersworld.com.

Pronation

Pronation is the inward movement of the foot as it rolls to distribute the force of impact of the ground as you run. The foot “rolls” inward about fifteen percent, comes in complete contact with the ground, and can support your body weight without any problem. Pronation is critical to proper shock absorption, and it helps you push off evenly from the front of the foot.

Although pronation is a natural movement of the foot, the size of the runner’s arch can affect its ability to roll, causing either supination (underpronation) or overpronation. If you have a normal arch, you’re likely a normal pronator, meaning you’ll do best in a stability shoe that offers moderate pronation control. Runners with flat feet normally overpronate, so they do well in a motion-control shoe that controls pronation. High-arched runners typically underpronate, so they do best in a neutral-cushioned shoe that encourages a more natural foot motion.

 

Normal Pronation

IThe outside part of the heel makes initial contact with the ground. The foot “rolls” inward about fifteen percent, comes in complete contact with the ground, and can support your body weight without any problem. The rolling in of the foot optimally distributes the forces of impact. This movement is called “pronation,” and it’s critical to proper shock absorption. At the end of the gait cycle, you push off evenly from the front of the foot.

Overpronation

As with the “normal pronation” sequence, the outside of the heel makes the initial ground contact. However, the foot rolls inward more than the ideal fifteen percent, which is called “overpronation.” This means the foot and ankle have problems stabilizing the body, and shock isn’t absorbed as efficiently. At the end of the gait cycle, the front of the foot pushes off the ground using mainly the big toe and second toe, which then must do all the work.
Preventing Overpronation Injuries 
Overpronation causes extra stress and tightness to the muscles, so do a little extra stretching. Too much motion of the foot can cause calluses, bunions, runner’s knee, plantar fasciitis, and Achilles tendinitis.
If you’re an overpronator, here are a few tips to help you find the right shoes for your feet.
  • Wear shoes with straight or semi-curved lasts
  • Look for motion-control or stability shoes with firm, multidensity midsoles and external control features that limit pronation
  • Use over-the-counter orthotics or arch supports

Underpronation (Supination)

Underpronation (or supination) is the insufficient inward roll of the foot after landing. Again, the outside of the heel makes initial contact with the ground. But the inward movement of the foot occurs at less than fifteen percent (i.e., there is less rolling in than for those with normal or flat feet). Consequently, forces of impact are concentrated on a smaller area of the foot (the outside part), and are not distributed as efficiently. In the push-off phase, most of the work is done by the smaller toes on the outside of the foot.
This places extra stress on the foot, which can lead to iliotibial band syndrome, Achilles tendinitis, and plantar fasciitis. Underpronating will cause the outer edge of running shoes to wear sooner. To see if your shoes are unevenly worn, place them on a flat surface. If they tilt outward, supination is the culprit. Runners with high arches and tight Achilles tendons tend to be supinators.
Preventing Underpronation Injuries 
Supinators should do extra stretching for the calves, hamstrings, quads, and iliotibial band. Wearing the right type of running shoes and replacing worn shoes will also help avoid injuries.
If you’re an underpronator, here are a few tips to help you find the right shoes for your feet.
  • Wear shoes with curved lasts to allow pronation
  • Look for lightweight trainers as they allow more foot motion
  • Check for flexibility on the medial (inner) side of the shoe

There is a common misconception that muscle soreness through exercise is inevitable and necessary to see results. For many, soreness acts as an indicator of a great workout. But this is a shortsighted view of exercise benefits and can have detrimental effects in the long run.

To clarify, this is not about the minor muscle stiffness that can be felt the day after a workout. This is about excessive soreness—the kind of soreness that lasts for a few days, has you avoiding stairs and dreading everyday activities such as putting on pants, getting in and out of a car, and even sneezing. Some people actually strive to experience this. And while a little soreness is safe and may motivate even the most sensitive among us, when it crosses the line toward debilitating movement, your body is telling you that you went too far.

The Science
In short, all muscle soreness is a result of microscopic tears that take place through workouts, followed by swelling as part of the repair and rebuilding process. This may sound like a violent way to treat your body, but it is a necessary process to stimulate changes that improve strength and fitness. But how much is enough? To answer this accurately, lets look at the available research and remove any anecdotal biases from the equation.

Cause and Effect
Many people argue in favor of soreness because they have experienced positive results and associate soreness with the results. But soreness does not necessarily equate with a cause and effect for the improvements. In fact, there is no scientific evidence that proves soreness gets better results. While there is a lack of research in this specific area, there is no shortage of research indicating that progressive challenges are responsible for improving fitness. The question then becomes, can we progress effectively without soreness? And the answer is a resounding YES.

Consider world-class athletes. No athlete, after falling short in competition, has ever said, “I should have trained to be more sore.” Yes, athletes do sometimes experience sore muscles from training. But it is neither the purpose nor the target of their training. In fact, workouts are often modified for athletes if they are experiencing excessive soreness. The measuring stick used to track success for an athlete has nothing to do with the level of soreness derived from day-to-day training and everything to do with the longer-term outcome of their training program and competition goals. In fact, too much soreness will negatively impact training and competition.

Overload
To improve fitness, it is true that an “overload” is required. This means you need to apply a challenge that is greater than what your body is accustomed to. However, this “overload” can be applied aggressively or it can be applied gradually. Many assume the more aggressively you overload, the faster you will see results. But the body is more complex than that and pain is its way of telling us to slow down with the overload.

Law of Diminishing Returns
Most improvements follow a basic premise of “the more you put in, the more you’ll get out.” However, there is a tipping point that suggests a certain level of extra work does not yield any additional benefits. In short, it means you are working overtime and not getting paid for it. This can be illustrated through the concept of exercise dosage. Much like medical prescriptions, too high of a dose does not provide additional benefits nor increase the speed of benefits. Additionally, repeated “overdosing” can invite negative consequences. Extreme soreness is often just that—an “overdose” to the body.

Why it is Important to Avoid Muscle Soreness?
The Hot Iron syndrome…
Most kids only need to touch a hot iron once. If you simply don’t like to feel pain, soreness is more likely to be a deterrent to exercise, not a motivator. In fact, it may be a subconscious reason it is so difficult to start up or get back to that first workout after a layoff.

Fitness should make everyday life easier, not harder…
Extreme soreness naturally alters choices for activity outside of workouts. If your weekly leg workout leaves you feeling sore for three days, and you choose escalators over stairs, it defeats the functional purpose of being more fit.

Tighten up those muscles…
This phrase, which is often used to describe a positive outcome, may literally mean “tighten” in this case. Consistent states of soreness can easily reduce range of motion and lead to permanent changes to your movement patterns.

Overtraining and overuse injuries…
Overtraining and overuse injuries take time to develop. Unfortunately, by the time they are noticed, you are too deep to reverse the process quickly. Aiming for and achieving soreness week in and week out is inviting either or both.

Distraction from more important goals of exercise…
Exercise and fitness success needs to have a far more sophisticated evaluation tool than the level of soreness. By aiming for soreness in the short term, we may be ignoring the true measurements of success for exercise, such as fitness, strength, functionality and longevity, among others.

How to Avoid Muscle Soreness and Still Achieve Great Results
Avoiding soreness is not the same as avoiding high intensities. High intensities and maximum effort can be reached through sensible and progressive overloading strategies. You just don’t want to start there. Gradual progressions are very effective and are a far more reasonable and comfortable way to improve fitness and reduce short- and long-term risks. This can be accomplished by understanding your current levels of fitness and strength, and applying small and frequent increases in intensities and volume according to where you are now—not the level you someday hope to reach.

Remember, fitness is built. It is not injected. Build it wisely…

Spring is upon us and that means that more people will be heading outdoors to go running. There’s nothing better for the mind and body than exercise, especially when it’s outdoors. However, avid runners are prone to overuse injuries that can hinder performance and possibly stop it altogether. Here are a few helpful hints that will help to keep you running throughout the warm weather months.
Injuries in runners generally occur in the legs and low back. The following are the most common along with some tips on how to prevent them from happening to you.

Low Back Pain- Eight out of ten Americans suffer from this. Running uphill for too great a distance can contribute to this because the torso will be swayed back into an uncompromising position. Running on uneven or hard surfaces can also cause back pain. Uneven surfaces cause asymmetrical forces on the lower back region while hard surfaces increase stress on the area due to increased force of impact on the ground.

* TIPS*
1. Run with proper trunk posture
2. Run on soft, even, dirt track with short, intermittent hills
3. Increase abdominal, back and leg strength to support low back
4. Stretch all trunk and leg muscles to prevent strains and tears

Hip or Buttock Pain:
1. Trochanteric (hip) Bursitis- This can result from increased stress to the outside of the hip as runners tend to overuse the muscles due to the one-legged stance

2. Piriformis Syndrome- The piriformis is one of the deep rotators of the hip. If this is tight, it can cause pain and increased pressure on the sciatic nerve as well as shooting pain down the leg.

* TIP*
STRETCH! Specific stretches are the ITB and piriformis illustrated at end of article

Anterior Knee Pain- This is common in most athletes, especially teenage girls. It is often due to poor body mechanics, faulty muscular strength, or poor muscle flexibility. This creates an abnormal tracking of the knee cap in the groove of the knee. This is usually easy to cure, but may require physical therapy or even surgery.

* TIP*
You should see a doctor to determine the best treatment options

Iliotibial Band (ITB) Friction Syndrome- This is lateral knee pain along the outside of the knee down past the knee. The one-legged stance in runners causes increased tightening of the ITB and will cause friction between it and the bony protuberances of the knee.

* TIP*
Again STRETCH that ITB!

Shin Splints- This is pain in the front of the shins. It is debatable what causes this but one factor is usually tight calf muscles, especially the soleus. Many hills can be the culprit of tight calves.

* TIPS*
1. Stretch the gastroc and soleus muscles
2. Monitor and modify hill training

Ankle Sprains- Usually caused by turning the ankle on a curved or uneven surface.

* TIPS*
1. Strengthen ankles
2. An ankle brace/support may help if you are prone to sprains

Asymmetrical Pain- Pain in one sector of the back or one leg vs the other probably means you are running on uneven surfaces. Many runners run on the crown of the road, so if you are always on the right side of the road, the left foot lands with the inside down and the right with the outside down.

* TIPS*
1. Find a flat surface to run on

In general, because of the repetitive pounding, battling elements, and the nature of runners to push themselves beyond limits, injuries will occur. Many of these injures start slowly and gradually become worse. Often there is not a specific cause of injury, which causes them to be overlooked until the pain limits activity.

The best prevention is to address pain when it first starts. To cure it, you may only need to do a few simple stretches, strengthening exercises, or maybe just changing running surfaces. However, at the onset of pain, if it is significant and lasts for at least a week, consult a physician.
Other Common Causes of Pain

Improper Footwear
Increasing intensity or distances too quickly
Running while sick or fatigued

* Final Tips *

1. Watch the Weather
-hypo vs hypotension
2. Wear Proper Clothing
-light, breathable material for proper sweat evaporation
3. Maintain Proper Fluid Intake
-drink water even before you feel thirsty
-sports drinks are fine
-don’t take salt tablets
4. Don’t be Overzealous
-don’t do too much too soon
-keep pace and distance to an achievable level
5. Stretch
-take the time to stretch every time you run
6. Wear Proper Sneakers
-you may need to be evaluated by a PT for this
-good sneakers vs orthotics
7. Enjoy and Don’t Push too Hard
