我们试图确定口服避孕药是否会改变在等长握力运动中观察到的运动加压反射的性别相关差异。15名男性、15名正常运动的女性（WomenNM）和15名服用双相口服避孕药的女性（WomenOC）完成了两项3分钟等长握力运动试验，在30%的最大自主收缩下进行：（1）在3分钟恢复期内对先前运动的手臂进行动脉闭塞（闭塞试验）;（2）在恢复期间未进行动脉闭塞（对照试验）。与两组女性相比，男性的平均动脉压（MAP）升高幅度更大（P
We sought to determine whether oral contraception alters the gender-related differences observed in the exercise pressor reflex during isometric handgrip exercise. Fifteen men, fifteen normally menstruating women (WomenNM), and fifteen women taking monophasic oral contraceptives (WomenOC) completed two trials of a 3-min isometric handgrip exercise protocol performed at 30% of their maximal voluntary contraction: (1) where arterial occlusion was applied to the previously exercising arm during a 3-min recovery period (Occlusion trial); (2) where no arterial occlusion was applied during recovery (Control trial). Handgrip exercise elicited greater increases in mean arterial pressure (MAP) in MEN compared to both female groups (P
