为了探讨月经周期对呼吸肌功能的影响，对30名健康成年女性在月经周期卵泡中期和黄体中期的呼吸肌和肺功能进行了测量和比较。呼吸肌力量以最大静态吸气和呼气压力表示。吸气肌耐力由压力负荷与持续时间的乘积确定，即压力-时间指数，受试者在改良的Nickerson-Keens装置上对吸气压力负荷进行呼吸。结果表明，黄体中期吸气肌耐力大于卵泡期（815 +/- 43比649 +/- 62 cmH2O）。分别为Min)，而呼吸肌力量和肺功能不变。我们的结论是，吸气肌耐力受月经周期的影响，即黄体中期较高，卵泡中期较低。
To investigate the effect of the menstrual cycle on respiratory muscle function, respiratory muscle and pulmonary functions were measured and compared in the midfollicular phase and in the midluteal phase of the menstrual cycle in 30 healthy adult women. Respiratory muscle strength was indicated by maximal static inspiratory and expiratory pressures. Inspiratory muscle endurance was determined by the product of pressure load and the sustained time, i.e., pressure-time index, while the subject breathed against an inspiratory pressure load on a modified Nickerson-Keens device. The results showed that the inspiratory muscle endurance was greater in the midluteal phase than in the follicular phase (815 +/- 43 versus 649 +/- 62 cmH2O.min, respectively), whereas the respiratory muscle strength and pulmonary function were unchanged. We conclude that inspiratory muscle endurance is affected by the menstrual cycle, i.e., higher in the midluteal phase and lower in the midfollicular phase.
