Running produces substantial force and shock to the joints, bones and soft tissue of the lower extremity through repetitively loading and unloading of those structures.  Every time the heel strikes the ground, a force of 5-10 times the athlete’s body weight must be absorbed by the soft tissue such as muscles, tendons, ligaments and cartilage.  Over time, this repetitive cycle can wreak havoc on those tissues.  The most vulnerable of the at-risk structures are the hamstrings, meniscus and Iliotibial Band (ITB).

The ITB is of specific interest because it is one of the most common conditions that plague the recreational and competitive runner.  The ITB is a fibrous tissue that runs down the outside (lateral) side of the upper leg from the hip to the knee.  One of the ITB’s main functions is to stabilize the knee joint.  Increased mileage means increased workload for all of the structures involved in running including the stabilizing ITB.  The increase in activity often results in increased tension in the ITB that will ultimately change the mechanics of the knee joint.  In the case of a tight ITB, the knee is constantly being pulled in one direction resulting in a lateral and torsion load on the knee joint that will wear out the other structures of the knee.  Think about driving your car when the wheel alignment is off.  The car will always be pulled to one side of the road, so you have to steer in the opposite direction.  After hundreds of miles of slightly “turning to the left”, the tires are going to wear out far quicker than if the wheels were aligned properly.  Not only does this lead to injury and pain symptoms, but performance declines as well.  The body must expend energy to overcome an intrinsic force resisting proper knee motion before it is able to expend energy to perform the intended task, in this case running.

Many runners are great about maintaining their strength and flexibility, and others are not.  However, most runners, in general, forget to stretch their ITB.  It is a simple structure to stretch, but not in the classic sense.  Most people view stretching as a ‘position and hold’ type maneuver.  While this is appropriate for many muscles, the ITB is a certain exception.  Because there is not a large range of motion associated with the ITB, it is very difficult to place the body in a position that will lengthen ITB.  The most effective way to stretch the ITB is to “roll it out”.  This is accomplished by placing a foam roll (think rigid pool noodle) on the ground.  Orient your body so that the outside of your leg is on top of the foam roll and the foam roll is perpendicular to the leg.  Hold your upper body off the ground with your arms and move your body back and forth over the foam roll so that the rolling like a rolling pin on the ground.

Foam rolls are inexpensive and can be purchased from most sports supply stores or our clinic for $15.  They are also available at most gyms and fitness centers.

Rolling out the ITB in conjunction with stretching the hamstrings and quadriceps on a regular basis goes a long way in keeping the recreational and competitive runner fast and pain free.

Happy running!

A multi-year Dutch study published in 2010, for example, showed a 62% lower risk of fatal heart attack in people consuming even a modest amount of EPA and DHA (about 234 mg per day) from fish as compared to those consuming little (about 40 mg per day)

The current recommendations for Vitamin D intake are about 1000 IU per day. This is equivalent to 10 cups of milk. Other sources of Vitamin D are salmon and sardines and of course sunshine. Although more research is needed to determine the ideal amount of vitamin D, the current recommendation is that you get 1000 IU of vitamin D from your diet or an inexpensive supplement plus get 10-15 minutes of sunshine per day. Due to our climate, many people do not get enough vitamin D during the fall and winter months so a Vitamin D supplement during these months would be recommended.

A study in 2007 found that postmenopausal women who took 1000 IU of Vitamin D plus Calcium had their cancer risk reduced by a half versus those who took the placebo or calcium alone. Other studies have shown similar benefits.

Vitamin D is free in the summer! Light skinned individuals who spend about 15 minutes in the sunshine can get several thousand IU (3,000-10,000 IU) of Vitamin D while darker skinned individuals would need more like an hour of exposure to get the same amount of Vitamin D.

So what do we recommend?
1) Get at least 1000 IU of Vitamin D from your diet (milk, sardines, salmon, etc) or take a supplement.
2) Get at least 10-15 minutes of sunshine exposure per day
3) If you cannot get enough sunshine exposure then take an additional 1000 IU supplement

Please check with one of our chiropractors or your family doctor before taking supplements.

Nobel prize winner, Dr. Alf Breig, says that “loss of the cervical curve stretches the spinal cord 5-7cm and causes disease.” Nobel Prize winner for brain research, Dr. Roger Sperry, found that “90% of the stimulation and nutrition to the brain is generated by movement of the spine.” According to a study in Physiology of the Joints by Kapandji, “For every inch of forward head posture, it can increase the weight of the head by an additional 10 pounds.” According to a study in Cephalgia in 2009 and Dr. Rene Cailliet at University of Southern California, forward head posture decreases respiratory muscle strength and can cause reduced vital capacity of the lungs by 30%. This shortness of breath can lead to heart and vascular disease.

All of this points to the fact that being in an unhealthy position for a prolonged period of time can cause a wide range of health problems. So sit up straight, keep your chin back, and take frequent breaks from sitting or staring at your Blackberry. It might save your life.
