Muscle Activity Adaptations to Spinal Tissue Creep in the Presence of Muscle Fatigue - Fig 3

<p><b>Mean RMS (A) and MDF (B) values over time on the right and left sides</b> (RMS: Root Mean Square; MDF: Median Frequency). Error bars indicate standard deviations. ★ represents a main effect of fatigue. ✦ represents a main effect of creep. Post hoc results are illustrated by * = <i>p</i> ˂ 0.01 and ** = <i>p</i> ˂ 0.001.
