Who could forget Rocky Balboa getting up at a crazy hour in the morning, washing down 3 raw eggs for breakfast and running the streets of Philadelphia. Forget the fact that he was wearing his Chuck Taylor's during training. When it comes to running and other sports injuries just as important if not more than the shoes we wear is how much recovery sleep we get,not over training and paying attention to strengthening his core and other leg stabilizing muscles in our trunk .
A study by Tracy Dierks, assistant professor of physical therapy at Indiana University, found that toward the end of a normal running session, runners generally displayed an increase in motion in their hips, knees and ankles. It is thought that larger movements lead to more injuries. This coincided with the runners' perceived level of exertion.
In a separate study conducted at the Manchester Marathon the running form of marathoners changed between the 10 and 32 km points. At the beginning most runners were using a forefoot to heel pattern while at the end it reversed.
We all know the effects of individual muscle fatigue on injuries, your leg muscles get tired and all of a sudden you injure your knee. EMG studies have shown that the anterior shin muscles fire 85 % over their fatigue threshold in running. Hence it is no surprise that many runners develop shin splints. It turns out that over all fatigue plays an important role just as localized muscular failure to an area. No one has been able to prove decisively why this happens but it is probably multifactorial. As our
form degrades with fatigue we are in a less stable position to prevent injury. It is also reasonable to assume that as you fatigue the brain's ability to execute precise movement patterns also degrades. What to do? Develop the core and support muscles. Heighten the body's spatial awareness with agility drills. This is why track work deconstructs the running stride and uses drills to help perform more efficiently.
So what can we conclude? Improper sleep, fatigue and over training are big factors relating to injury. To help counter this we can do specific training exercises to strengthen some of the muscles that degrade before injury. Maybe Rocky was on to some by not wanting to break training with Adrienne!
You ever find yourself up one night clicking through for the local ESPN station and come across one of these hucksters pushing some magic elixir that's going to change your life?? It's pretty funny. It is also shocking how many people get on board the cable and internet health train. Just a modern version of the traveling medicine man pedaling stuff out of the back of a wagon, really. This particular guy goes on a rant how there is no good evidence supporting supplements with glucosamine and then tells you how you are going to become arthritis free with their natural product backed by studies. Guess what the magic ingredient is?? Right, glucosamine! What about the satisfaction guaranteed part? How many people that buy this stuff off a cable TV ad have it together enough to save the receipt , unused product and get it sent out to the post office in 30 days? I'm guessing about the same number that have an old Motown Blue Magic "Sideshow" 45 somewhere in their attic.
I started this blog to share cutting-edge knowledge from my medical practice and my experience with athletes and as an athlete myself. I was a walkon at I.U. for track and after getting hurt my first season switched over to bike racing and raced in the "Little 500". I teach skiing professionally and also fit soccer in between bike riding and running. You know who you are: the weekend warrior and more serious athletes: the best insights, protocols, tips, and tricks for training and living injury free. I welcome your feedback.
