Hormone and Tendon stiffness measurement in female runner athletes between 18-55 yrs.
Summary
Our study goal is to recruit two groups of runners who are active, healthy females between the ages of 18-35 and 35-55 years old. We are including individuals who are both naturally menstruating (pre-menopausal) and those that have at least 9 cycles a year but may have changes in menstrual flow and in the length of the cycle (peri-menopausal).
We are studying the tendon stiffness differences in hormone levels by age groups; and (2) whether there is an association between achilles tendon stiffness-ability to gerenerate force and hormone levels (estrogen and progesterone) regardless of age during a running treadmill protocol.
