(A) Comparison of peak torque production in COL6-RD, DMD and control groups. (B) Comparison of peak torque normalized to Non-Fat area between COL6-RD, DMD and control groups. *significantly different between DMD and COL6-RD at p < 0.05. +Significantly different from control at p < 0.05. COL6-RD- Collagen VI related dystrophy, DMD- Duchenne Muscular Dystrophy, KE – Knee extensors, PF – Plantar Flexors.
