Figure 2.

Three daily bouts of low intensity vibration on mdx mouse posterior crural muscle contractility were compared to other exercise modalities in Study 2. Data are mean, SE. A: Peak isometric torque and rates of contraction and relaxation were not detrimentally affected by vibration. Main effect P-values from one-way ANOVA’s are indicated above each set of bars. Despite the significant main effect for peak isometric torque, post-hoc testing did not detect a significant difference among any of the four groups. B: Isometric torque as a function of stimulation frequency for non-vibrated Control, Vibrated, Wheel running and Eccentrically injured mdx mice. ^aSignificant difference determined from post-hoc testing with torque by Vibrated mice greater than that by Eccentric mice.
