Brief Summary

DHEA or dehydroepiandrosterone is a naturally occurring hormone secreted by tghe adrenal galnds. The secretion of HDEA declines with aging. DHEA is considered a food supplement and it is not regulated by the FDA. The purpose of this research is to evaluate ceratin of the biological effects of a reaplcement dose of DHEA. As you get older, DHEA levels are lower than you were younger. The replamcent dose is the dose of DHEA that will raise DHEA levesl to the levels found in young people. Anotehr purpose is to determine whether DHEA enhances the adaptations to an exercise training program.
