Peripheral and central fatigue cause similar decreases on dynamic postural stability in male recreational runners.

Decreased dynamic postural stability could be linked to a great number of injuries. Moreover, fatigue -both central and peripheral- may diminish dynamic postural stability and have an impact on injuries. Therefore, the main objectives of our study were to identify and compare the effects of central and peripheral fatigue on dynamic postural stability. The Modified Star Excursion Balance Test (mSEBT) in anterior, posterolateral and posteromedial directions was performed in eighteen male recreational runners before and after a central or peripheral fatigue protocol. Central fatigue was induced by a 30-minute run at 85% of maximal aerobic speed on a treadmill, while a localized fatigue protoco…
