How long should you wait between running marathons and what in the mean time should you be doing that will both help recover from the last one and prepare for the next?
There is no simple answer to your question, because there are so many variables that affect an individual’s response to running and exercise. A persons BMI (body mass index), for example intuitively will affect how much trauma the joints sustain during running. Then, there is genetics. Some people are more prone to osteoarthritis than others and may not respond to running distance as well as others. What about cardiovascular issues, diabetes, anatomical differences such as flat feet? I could go on indefinitely.

However, there is one way we are all alike. Our body has an amazing ability to adapt to stress. So, in order to avoid overuse injury and trauma to the joints, we each have to figure out as individuals, how our body responds. As an example, if a person with normal BMI, no health problems, normal orthopedic exam (anatomy) and no history of running more than 6 miles asked me this question, I would say start with one marathon per year and double that every year of continuous training using a 16 week regimen to prepare for big race. This allows the body adequate time to build up bone density, ligament strength, cardiovascular stamina and fluid maintenance to prevent injury. Take 6-8 weeks off per year from running and focus on strength training, biking, swimming, etc.

Just remember, that overuse injuries and stress fractures are purely dependent on the “rest/workout ratio”. Therefore, a good rule of thumb is not to increase your intensity or volume of training more than 10%/week and always cross-train (i.e. bike one day a week when marathon training).

When undergoing an MRI at AOC for the left leg and left kneeā€¦..Is the MRI machine opened or closed? How long is the procedure?
We have two MRIs at AOC. The first is a 1.5T short bore, which means it has a wide opening for the patient with a portion of the body not being scanned possibly extending outside of the magnet. The second MRI is a 0.7T open magnet.
The typical scan time ranges for about 22 minutes for a knee MRI to about 30 minutes for a wrist. A more complicated body part, such as a pectoralis tear, may take 35-40 minutes. The scan times for the open magnet runs about 2-3 minutes longer per study, although both magnets produce excellent images and they are both accredited by the American College of Radiology. Scan times are also subject to various factors (IE. patient compliance, patient’s body type, or even a specific diagnosis by the ordering physician).
Intravenous contrast for our MRIs is not typically needed for sports injuries, although we may use contrast for patients with recent lumbar surgery or for investigating a soft tissue unknown mass.
