Currently many women cannot meet military requirements for heavy and very heavy lifting tasks. The overall goal of this proposal is designed to discover which type of women's strength training is most effective for achieving the result the Army wants. We intend to determine the contribution of upper body strength training to meet this goal. Our strategy will be to then transfer our initial findings to a strength training program for field unit use. For comparison and determination of program effectiveness, a group of 100 untrained men will serve as "standards'. Although the study will take three years, the formal training will take six months with testing at three month intervals. The training program utilizes the most advanced programs in resistance training. Tests include neuromuscular strength and power tests, electromyography and magnetic resonance imaging for muscle size. Performance tasks which are uniquely relevant to the military will be performed. We will monitor selected physiological changes which are taking place in the blood of women during and after training. Because we know that many women may not tolerate high intensity training (i.e. the 'overtraining syndrome'), we propose to monitor immune status as an indicator of health. We will also measure certain anbolic hormone levels in the blood of the test subjects because they are known to be key regulators of muscle size and neuromuscular function. We believe that the blood levels of anabolic hormones will change depending upon which of the six training programs is used: if so, we should be able to correlate performance achievement with hormone concentration. The product of this effort would be the development of "blood markers of trainability". Such a product would be extremely useful to achieving the goal of attaining and maintaining women who are able to meet these military requirements. In summary, our training programs will establish: 1) the maximal gains in physical performance that are possible in untrained women; 2) how that maximal performance compares to that of the average male; and 3) markers of health and trainability that could be routinely used in large field training efforts in the future.

目前，许多妇女不能满足军事上繁重和非常繁重的搬运任务的要求。 这项提案的总体目标是发现哪种类型的妇女力量训练是最有效的实现军队想要的结果。 我们打算确定上肢力量训练对实现这一目标的贡献。 我们的策略是将我们的初步发现转移到一个力量训练计划中，供野战部队使用。 为了比较和确定计划的有效性，一组100名未经训练的人将作为“标准”。 虽然这项研究将需要三年时间，但正式培训将需要六个月，每隔三个月进行一次测试。 训练计划采用最先进的阻力训练计划。 测试包括神经肌肉力量和力量测试，肌电图和肌肉大小的磁共振成像。 将执行与军事有关的独特任务。 我们将监测妇女在训练期间和训练后血液中发生的某些生理变化。 因为我们知道许多女性可能无法忍受高强度训练（即“过度训练综合征”），我们建议监测免疫状态作为健康指标。 我们还将测量测试对象血液中的某些促性腺激素水平，因为已知它们是肌肉大小和神经肌肉功能的关键调节器。 我们相信，血液中合成代谢激素的水平会根据使用六种训练计划中的哪一种而变化：如果是这样，我们应该能够将成绩与激素浓度联系起来。 这一努力的成果将是开发“可训练性血液标志”。 这种产品将非常有助于实现获得和维持能够满足这些军事要求的妇女的目标。 总之，我们的训练计划将建立：1）未经训练的女性可能获得的体能最大收益; 2）与平均男性相比，最大表现如何; 3）健康和可训练性的标志物，可以在未来的大型野外训练中常规使用。
