Analysis of GL architecture at the neutral ankle position along (regions P, C and D) and across (sections M, MS and L) its belly (see Fig. 3), at rest and during an ankle plantarflexor MVC. Mean ± s.d. values from three subjects on which all measurements were taken are presented, except

^†values from all six subjects.
