The purpose of the study was to 1) determine the effects of a low-volume resistive exercise protocol on serum concentrations of estradiol (E2), progesterone (P4), growth hormone (GH), testosterone (T), and androstenedione (AN) and 2) ascertain whether the endocrine responses are affected by the phase of the menstrual cycle. Eleven untrained, healthy women were assigned to either an early follicular or luteal testing group. The subjects completed three sets of bench press, lat-pull, leg extension, and leg curl exercises at a 10 repetition maximum load on fixed machines with 2-min of rest between sets. Blood samples were collected through an indwelling cannula before, during, and after the exercise. Area-under-the-response-curve (AUC) data demonstrated that E2 concentrations were significantly elevated in both follicular and luteal phases with a greater response in the luteal phase. Moreover, data suggest there is a luteal phase-induced increase in GH and AN in response to the low-volume resistive exercise; however, P4 and T concentrations in untrained women are not increased by low-volume resistive exercise with 2-min rest periods, nor does the altered hormonal milieu produced by the phase of the menstrual cycle affect these hormonal responses.
1）确定低容量抗阻运动方案对雌二醇（E2）、孕酮（P4）、生长激素（GH）、睾酮（T）和雄烯二酮（AN）血清浓度的影响；2）确定内分泌反应是否受月经周期阶段的影响。11名未经训练的健康女性被分配到卵泡期早期或黄体期测试组。受试者在固定器械上以每组重复10次的最大负荷完成三组卧推、引体向上、腿部伸展和腿部卷曲练习，组间休息2分钟。在运动前、运动期间和运动后通过留置套管采集血样。反应曲线下面积（AUC）数据表明，卵泡期和黄体期的E2浓度均显著升高，黄体期的反应更大。此外，数据表明，黄体期会因低容量抗阻运动而导致GH和AN增加；然而，休息2分钟的低容量抗阻运动不会使未经训练女性的P4和T浓度升高，月经周期阶段产生的激素环境变化也不会影响这些激素反应。
