Muscle strength of the adductor pollicis (AP) was studied throughout the menstrual cycle to determine whether any variation in force is similar to the known cyclical changes in ovarian hormones. Three groups of young women were studied: trained regularly menstruating athletes (trained), untrained regularly menstruating (untrained) and trained oral contraceptive pill users (OCU). In addition a group of untrained young men was studied as controls. 2. Maximum voluntary force (MVF) of AP was measured over a maximum period of 6 months. Ovulation was detected by luteinizing hormone measurements or change in basal body temperature. There was a significant increase in MVF (about 10%) during the follicular phase of the menstrual cycle when oestrogen levels are rising, in both the trained and untrained groups. This was followed by a similar in MVF around the time of ovulation. Neither the OCU nor the male subjects showed cyclical changes in MVF.

研究了拇收肌（AP）的肌肉力量在整个月经周期中的变化，以确定力量的任何变化是否与已知的卵巢激素周期性变化相似。研究了三组年轻女性：定期训练的经期运动员（训练组）、未训练的定期经期女性（未训练组）和服用口服避孕药的训练女性（OCU组）。此外，还研究了一组未训练的年轻男性作为对照。2. 在最长6个月的时间内测量AP的最大自主力量（MVF）。通过黄体生成素测量或基础体温变化来检测排卵。在月经周期的卵泡期，当雌激素水平上升时，训练组和未训练组的MVF均显著增加（约10%）。随后在排卵前后MVF也有类似变化。OCU组和男性受试者的MVF均未显示出周期性变化。
