Fig. 5. The relationship between peak strain (strain at Po) and
muscle-tendon unit (MTU) length for each of the five segments defined in this
study: DA, dorsal aponeurosis; MA, middle aponeurosis; PA, proximal
aponeurosis; PT/DA, proximal tendon/distal aponeurosis; TEND, tendon. Strains
in the tendon were significantly (P<0.05) less than those in all
regions of the aponeurosis and did not vary significantly with increasing MTU
length. By contrast, peak strains in the aponeurosis tended to increase with
lengthening of the MTU. Values are means ± 1 S.D.
(N=4).
