Note: (a) the P values under the force data are the paired t-test of the forces at the specific time point compared to that measured at the prior time point (e.g., WT force at 20 min compared to that at 10 min); (b) the P values in the last row are the unpaired t-test of forces between WT and dysferlin-null groups at each time point.
