Fig. 6. The relationship between stiffness (N/% strain) and muscle-tendon unit
(MTU) length for each of the five segments defined in this study; for
definitions of abbreviations, see Fig.
5. Tendon stiffness was greater than that of all regions of the
aponeurosis and did not vary significantly with increasing MTU length. The
stiffness of the aponeurosis was relatively constant across lengths but was
significantly (P<0.05) higher at Lo+2 mm than
at any other length. Values are means ± 1 S.D.
(N=4).
