This past weekend I had a chance to adjust runners after they finished marathons, half marathons, and 50K races. After seeing a lot of people in pain, I decided to do some research on safe training and recovery as well as the risk of endurance training.



Over the last several years there have been reported deaths during marathons of experienced and inexperienced runners alike. Have the risks increased?



The answer is no - the risk of sudden cardiac death (SCD) is still 1 in 100,000 people. What has changed is the number of people who are participating in these races (an increase of twentyfold of the past 30 years)! Although it’s great to see more people exercising and getting into shape, there are some risks and things to avoid.



Contrary to popular belief it is actually the younger population that is more likely to be at risk than the older population. Individuals over 40 may already be diagnosed with a disorder such as coronary artery disease and thus be more aware of their limits.



Those under 40 may never know that anything is wrong until it’s too late due to underlying conditions of the heart. Although the risk is rare (1 in 100,000) it is still a concern and is being researched more and more recently.



During training the left ventricle wall actually increases in thickness, the heart increases cardiac mass overall, and the left atrium increases in size as well. In the general population this is considered predictive of a poor cardiac outcome.



These changes are no longer thought to be harmless in athletes. Over time this dilation may result in cardiac scarring which can trigger arrhythmias and fibrillation. After a marathon 50% of runners have increased levels of biomarkers (which assess cardiac damage) and renal (kidney) dysfunctions.



However, our bodies are able to adapt to these changes when they occur in small amounts. With sufficient recovery, your body will heal itself. However, repeating training and recovery over and over again can lead to structural changes which result in fibrosis and scarring.



Another study showed aortic stiffness in marathoners which is associated with cardiovascular risk for any population. Marathoners’ higher artery calcium and plaque levels lead to decreased diastolic filling time. These issues contribute to scarring which can cause fatal arrhythmias and fibrillation.



Currently the only indicator to look for in younger runners (under 40) who might be genetically predisposed to heart problems is a very expensive cardiac MRI. In most cases a cardiac murmur may be all that shows up in physical exam (75%).



However, running is still beneficial: in moderation, it causes a 19% overall reduction in all-cause mortality. According to studies the most effective way to run is 2-5 times per week, 1 to 20 miles per week, and at a pace of 6-7 miles per hour. No benefits were seen going beyond this recommended amount and running more than these amounts can actually be worse for your health in the long run.



Some things you can do to decrease the risk of endurance training: Increase recovery time, make sure you get enough sleep, eat a healthy diet, and manage stress. After running there is an increased risk of upper respiratory tract infections, so make sure to rest, stay hydrated, and replace lost electrolytes.



A 4:1 carb to protein level is recommended for recovery for any exercise over 60-90 minutes. This ratio stimulates muscle protein synthesis at a higher level. Also, according to studies, vitamins E and C have been shown to partially prevent skeletal muscle damage caused by exhaustive exercise.



Running is still very good for you and risks are low. Don’t let these studies stop you from running - just take precautions and remember that proper rest and recovery afterwards makes all the difference.

Nervous system flowing out through the spine
Nervous system flowing out through the spine

Above, Down, Inside, Out: describes the flow of nervous system communication in your body.


Your brain sends signals down the spinal cord, which run through your vertebrae (inside) and travel through nerves to every area of your body.



Chiropractors work with the nervous system through the spine and with the individual nerves in places like shoulders, knees, wrists, elbows, ankles and even fingers and toes.


Our bodies have an ability to heal themselves. When you were a child and scraped your knee did you need a prescription or surgery? No, your body took care of that cut on its own!


Our goal is to get your nervous system functioning at its highest level so that your body can heal itself.


Two people can be in the same room and touch or eat the same thing and one gets sick but the other doesn’t. Why is this? One person’s body has the ability to fight off infection and remain unaffected, while the other simply isn’t able to perform at the same level. There are other factors that may play a role in this - however, on some level one person adapted better than the other.


So why does your body need to be adjusted? When nerve flow gets impeded we call this “subluxation”, simply meaning a bone is out of place or a joint isn’t moving properly and we want to restore motion and nerve flow.


There are 3 ways in which subluxation occurs:


1. Physical Stress: Obvious examples would be a fall, sport’s injury, or car accident. However, some

other examples are less obvoius. Birth maybe one of the most traumatic things we go through in life.

Sixteen hours of pressure on your head can be very traumatic and if forceps are used on your head and

neck it can cause further issues. Another example: Looking down at a computer screen or cell phone can

be very straining on your neck, in between your shoulders and even your low back.


2. Emotional Stress: If you are constantly depressed or angry and thinking negative thoughts all the time

not only does this effect your mood and personality but it also can affect your body through the spine or

other joints.


3. Chemical Stress: If we are constantly putting things in our bodies that aren’t healthy or even harmful,

our bodies will experience negative effects and this includes the spine.
