INTRODUCTION: The aging process is reportedly associated with connective<br />
tissue changes, although no data exists to substantiate such changes in elderly<br />
women. The present study investigated the effect of age on the crosssectional<br />
area (CSA) of the Achilles tendon.<br />
METHODS: The CSA was obtained with MRI in young (Y) healthy untrained<br />
women (n=9, age=290.7 yrs (meanSE)) and elderly (E) healthy untrained women<br />
(n=10, 79.41.9 yrs). Mean CSA was obtained from 3 measures 3 cm proximal<br />
to the Achilles tendon insertion. CV for the measures was 3.4 %. Achilles<br />
tendon force was obtained from maximal i<strong>som</strong>etric ankle moment and moment<br />
arm data from MRI. Pearson correlation coefficients and unpaired t-tests<br />
were used for statistical evaluation.<br />
RESULTS: (meanSE) Y and E did not differ in height (Y: 1673 cm, E: 1633 cm)<br />
or weight (Y: 71.34.4 kg, E: 62.13.6 kg). Achilles tendon CSA was greater in E<br />
(56.3+3.0 mm 2 ) compared to Y (46.0+ 1.9 mm 2 ), P 0.01. Tendon force was greater<br />
in Y (1930393 N) compared to E (982107 N), P
