Figure 3From: Effects of fatiguing isometric and isokinetic ankle exercises on postural control while standing on firm and compliant surfacesChanges in ML CoP velocity and variability. Mean and standard deviation of CoP parameters in ML (pooled data from isometric and isokinetic fatiguing exercises). ML CoP velocity (A) and ML CoP variability (B) significantly increased with fatigue when standing on the compliant surface only. ** p < 0.01; *** p < 0.001.Back to article page
