Objective: To investigate the changes in sex hormones of female members of marines amphibious bri-gade reconnaissance team after maritime training, and observe the effects of the training on physiological functions of women. Methods: According to the standard scout training syllabus, a marine amphibious brigade reconnais-sance team of 30 female players underwent training from June to July for a total of 60 days, with 7 hours per day. Blood were collected one day before the training, at the moment that the training was just finished and 90 days later. Microparticle enzyme-linked immunosorbent assay was used to assess the levels of follicle stimulating hormone, luteinizing hormone, estradiol, progesterone, prolactin and testosterone in serum. Questionnaire survey was done to assess the change in height, weight, menstrual and nutrition status of female members before and after the training. Health education and psychological intervention were applied to the members after the training to help the members to recover. Results: The levels of these endocrine hormones were markedly decreased compared to those in the day before the training, and athletic menstrual cycle irregularities appeared more frequently in fe-male members one day after the training. However, the levels of these endocrine hormones in female members at 90 days after the training were significantly higher than those when the training was just finished(P<0.05). In ad-dition, the menstrual disorders were obviously recovered 90 days after the training. Conclusion: The female hor-mone disorders caused by high-intensity training program under high temperature and high humidity environmental conditions can be restored through enough rest and a balanced diet, which provide a basis for scientific maritime training to reduce the occurrence of training-related menstrual disorders in female members.%目的：通过监测海军陆战旅两栖侦察队女队员海练前后内分泌性激素的变化，观察海练对女性生理功能的影响。方法：海军陆战队某旅两栖侦察队女队员30名，按侦察兵训练大纲的标准于每年6~7月进行海练，每天训练7h，共60d。于海练前1d、海练后1d和海练后第90d抽血，采用微粒子酶联免疫法测定其血清促卵泡生成素、促黄体生成素、雌二醇、孕酮、泌乳素和睾酮的水平；通过问卷调查了解女陆战队员身高、体重、月经周期变化和营养等状况，并进行健康宣教和心理干预。结果：女队员海练后1d较海练前1d内分泌性激素水平显著降低，差异具有统计学意义（P<0.05）；海练后1 d，女队员月经失调的情况明显增多（P<0.05）；海练后第90 d内分泌性激素水平较海练后1 d显著升高，差异具有统计学意义（P<0.05）；海练后第90 d，女队员月经失调的情况显著改善（P<0.05）。结论：在高温高湿环境下长途奔袭、渡海、抢滩登陆等高强度海练造成的女陆战队员内分泌性激素水平改变及月经失调，可通过适当调整训练量和强度、平衡饮食保证能量供应、实施心理干预等措施降低其发生率，这为科学海练提供了依据，同时可预防运动性月经失调的发生。
