In a recent Runners’ World article, it was brought out that by adjusting your running, you can avoid injury. The author correctly brought out that faulty running is a major cause of injury. Typically, this happens when you try running longer or faster, at which time your running form breaks down, leading to injury. His recommendation was to keep doing checks on your form to make sure you are running effectively and thus, prevent injuries.
But, when you are tired, as you usually are near the end of a race or when running faster, it becomes almost impossible to check on or correct your running form. Your form will automatically change with fatigue. More effective than merely doing checks on your form would be to do physical exercises to strengthen the muscles so that you can go faster and longer without any major changes in technique. It’s easy to say that you should adjust technique, but muscles that don’t respond when you are tired make it impossible to effectively change technique the way you must to prevent injury.
