Eccentric Exercises to Increase Run Durability
by Jeff Shilt, M.D.
I've written in the past regarding the benefits of eccentric exercises for rehabilitation of a variety of overuse injuries. I also feel strongly that eccentric leg exercises are very valuable in strength training for runners who may have biomechanical limitations in regard to training volume.
I will commonly reduce training volumes in athletes with these concerns and replace some training with eccentric exercises to increase the durability in the muscles crucial for running. Note that most of these exercises were developed to fix chronic tendinopathy. In this use, returning the limb to neutral by the uninjured limbs is important. This isn't the case in using the eccentric training for increasing run durability.
My routine includes strengthening the following muscles:
The eccentric strengthening of the muscles allow them to be more resistant to the destruction we see during race efforts and hard running.
I hope you find these helpful.
