Table 3.
Similarity of muscle force, normalized muscle fiber length, and muscle activation predictions between the two approaches. Similarity was quantified using mean and standard deviation of MeanD, RMSD, and r values for Approach B relative to Approach A. Statistically significant differences (p < 0.05) in MeanD are indicated by an asterisk (*).
