Maximal inspiratory mouth pressure (MIP) is a common measurement of inspiratory muscle strength, which is often used in a variety of exercises to evaluate the effects of inspiratory muscle training. The characteristics of MIP in elite female athletes remain unclear. This study aimed to determine the characteristics of MIP at rest in a variety of sport-specific elite female athletes. We also aimed to clarify if there is a sex difference of MIP in elite athletes. We studied 169 Japanese elite female athletes and 301 Japanese elite male athletes. MIP was assessed using a portable autospirometer with a handheld mouth pressure meter. Female athletes who regularly experienced exercise-induced inspiratory muscle fatigue tended to have higher MIP values. The mean absolute MIP value in females was significantly lower than that in males. However, when this value was expressed relative to body mass, this difference disappeared. Our findings provide essential information for prescribed, sport-specific, inspiratory muscle training in elite female athletes.
最大吸气口腔压力（MIP）是吸气肌力量的常用测量指标，常用于各种运动中以评估吸气肌训练的效果。精英女性运动员的MIP特征尚不清楚。本研究旨在确定各类特定运动项目的精英女性运动员静息时的MIP特征。我们还旨在阐明精英运动员中MIP是否存在性别差异。我们研究了169名日本精英女性运动员和301名日本精英男性运动员。使用带有手持口腔压力计的便携式自动肺活量计评估MIP。经常经历运动诱发吸气肌疲劳的女性运动员往往具有较高的MIP值。女性的平均绝对MIP值显著低于男性。然而，当该值相对于体重表示时，这种差异消失。我们的研究结果为精英女性运动员进行特定运动项目的吸气肌训练提供了重要信息。
