Values are means and (s.d.), N=number of specimens.

(T), specimen obtained from region subject to habitually prevalent/predominant tensile strains; (C), specimen obtained from region subject to habitually prevalent/predominant compressive strains.

This region receives predominant tension at higher gait speeds.

*N=19; **N=18; N=9; N=8.

A-FSignificantly different (P<0.05) from test mode/region indicated by superscripted letter.
