Muscle fascicle lengths produced by the model, normalized by optimal muscle length, and averaged over all subjects.

<p>The error bands of these profiles represent the standard deviation over different participants and their spread is largely provided by a constant offset rather than different shapes, as evidenced by the relatively constant standard deviations (over time) and <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004912#pcbi.1004912.g008" target="_blank">Fig 8</a>.
