The influence of resistance exercise and training on hormone levels of postmenopausal females.

摘要

The goal of this study was to determine if resistance trained postmenopausal females had elevated steroid hormone levels compared to untrained subjects and to evaluate the effect of different resistance exercise volumes on these hormones.;Twelve volunteer subjects were recruited for the first phase; six who had been resistance training for a minimum of one year and six untrained control subjects. These subjects were matched for age and use of hormone replacement therapy. All subjects completed the Canadian Physical Activity, Fitness and Lifestyle Appraisal and a blood sample was taken in order to measure resting levels of DHEA, DHEAS, testosterone, and cortisol.;For the second phase, five postmenopausal women who had been resistance training for a minimum of one year were recruited. Each subject completed three supervised sessions; one with one set of eight exercises at 10RM intensity, one with three sets of eight exercises and one resting control session. The three sessions were randomized for order and performed at the same time of day. Blood samples were taken before, immediately after, and one hour after each session. All samples were analyzed for DHEA, DHEAS, testosterone, and cortisol. (Abstract shortened by UMI.).
