1. 研究了月经周期不同阶段对19例月经规律的女性骨骼肌收缩特性的影响。在(1)雌激素和黄体酮浓度低（月经）、(2)雌激素升高和黄体酮低（卵泡晚期）、(3)雌激素和黄体酮均升高（黄体期）时测量肌肉功能。测量了最大等长四头肌强度、疲劳性和电刺激收缩性能。等速膝关节屈伸强度和疲劳也被评估，以及握力。通过测定雌激素、黄体酮、促卵泡激素和促黄体生成素来确定月经周期。在整个月经周期中，没有发现任何肌肉功能参数有显著变化（n = 15）。肌肉功能测量显示与任何雌性生殖激素浓度没有显著的相关性。这些结果表明，在整个月经周期中，女性生殖激素浓度的波动不会影响肌肉收缩特性。
1. The influence of the different phases of the menstrual cycle on skeletal muscle contractile characteristics was studied in 19 regularly menstruating women. Muscle function was measured when (i) oestrogen and progesterone concentrations were low (menstruation), (ii) oestrogen was elevated and progesterone was low (late follicular phase), and (iii) oestrogen and progesterone were both elevated (luteal phase).2. Maximal isometric quadriceps strength, fatiguability and electrically stimulated contractile properties were measured. Isokinetic knee flexion and extension strength and fatiguability were also assessed as well as handgrip strength. Menstrual cycle phases were confirmed through measurement of oestrogen, progesterone, follicle stimulating hormone and luteinising hormone.3. No significant changes were found in any of the muscle function parameters throughout thf menstrual cycle (n = 15). The muscle function measurements showed no significant correlations with any of the female reproductive hormone concentrations.4. These results suggest that the fluctuations in female reproductive hormone concentrations throughout the menstrual cycle do not affect muscle contractile characteristics.
