对19例未经训练的初潮女性（平均年龄31.1 +/- 1.1岁，身高165.2 +/- 1.4 cm，体重64.8 +/- 2.1 kg，峰值摄氧量（Vo2） 41.6 +/- 1.4 ml.kg-1）的促黄体生成素（LH）和生长激素（GH）释放的脉动特性进行了评价。Min-1]在月经周期的卵泡早期（月经开始后3-4天）。每个受试者在两个连续的月经周期中按随机顺序进行研究：1)72小时内没有正式运动(C); 2)连续几天（EX）进行两次最大运动（峰值Vo2/乳酸阈值跑步机评估和3200米计时试跑或最大Vo2倾斜跑步机测试）后12-24小时。每10 min采血一次，持续12 h。通过聚类脉冲检测算法识别和表征LH和GH脉搏参数。在LH或GH的峰数、峰幅、峰间间隔、峰增量或12 h综合浓度方面，C和EX之间没有显著差异。我们得出的结论是，如果在评估促性腺激素或生长激素的脉动分泌之前允许12-24小时的恢复，通常用于运动评估的最大运动方案对未经训练的女性在月经周期卵泡期早期的LH或GH释放的脉动特征没有影响。
Pulsatile properties of luteinizing hormone (LH) and growth hormone (GH) release were evaluated in 19 eumenorrheic untrained females [mean age 31.1 +/- 1.1 yr, height 165.2 +/- 1.4 cm, weight 64.8 +/- 2.1 kg, peak oxygen uptake (Vo2) 41.6 +/- 1.4 (SE) ml.kg-1.min-1] during the early follicular phase of the menstrual cycle (days 3-4 after the onset of menses). Each subject was studied during two consecutive menstrual cycles under each of two conditions in random order: 1) no formal exercise for 72 h (C) and 2) 12-24 h after two maximal exercise bouts (peak Vo2/lactate threshold treadmill evaluation and a 3,200-m time-trial run or a maximal Vo2 inclined treadmill test) performed on consecutive days (EX). Blood sampling was performed every 10 min for 12 h. LH and GH pulsatile parameters were identified and characterized by the Cluster pulse detection algorithm. No significant differences were noted in the number of peaks, peak amplitude, interpeak interval, peak increment, or 12-h integrated concentrations between C and EX for LH or GH. We conclude that maximal exercise protocols typically used for exercise evaluation do not have an effect on the pulsatile characteristics of LH or GH release in untrained women during the early follicular phase of the menstrual cycle if 12-24 h of recovery are allowed before evaluation of the pulsatile secretion of gonadotropins or GH.
