Peroneus Brevis Tendinitis in Runners

What this episode covers

In the earlier episodes we explained that peroneal tendinitis is just inflammation of one of two tendons on the outside of your ankle: peroneus brevis and peroneus longus. In most runners these are overuse injuries. Although they have similar names and they’re both in a similar location they each have very different functions when you run. In the simplest terms, they work together to act as your landing gear when your foot hits the ground and you decelerate. They both stabilize your foot. But these two tendons stabilize your foot in very different ways. In this episode we’re going to focus specifically on the peroneus brevis tendon, how it works, how it becomes inflamed, and what you can do to make sure that you calm it down. We will also discuss how you can strengthen the peroneus brevis so it doesn’t become a problem again that could disrupt your running in the future.
