How to maintain good running form with fatigue

Is this you at the end of a race?😂

It is no secret that as fatigue sets in during a run, there are changes to running technique and loading forces. Called ‘Early Foster’ collapse position, these changes include unstable steps, an increase in trunk forward bend and lowered head-position (Claire-Gibson et al, 2013). Furthermore, the ankles will often lose their alignment (Increased eversion) causing higher vertical impact forces (Koblbauer et al, 2014).

So what’s the best way to combat fatigued running and get better race photos? 🏃🏻‍♀️

Awareness of posture and quieter running has been shown to reduce degradation in running technique (Pirscoveanu et al, 2021). So practising this and ensuring you’re sufficiently trained for a race will allow running strong right till the end.

As for strength training, Koblbauer found that core endurance did not influence the degree of trunk fatigue, but they theorized that fatigue of the leg (calves) would then increase the demand on proximal muscles of the trunk and hips. So strength training could still benefit here, but it doesn’t necessarily need to be the core!
