DESCRIPTION (provided by applicant): Back pain is a common health problem among pregnant women. Back pain can have important adverse consequences including a reduced quality of life and a reduced ability to function well both at work and at home. Given that many women prefer to avoid taking medications during pregnancy it is useful to consider non-pharmacological approaches to minimizing back pain and improving quality of life. Moderate intensity resistance exercise training offers a plausibly effective method for attenuating back pain among pregnant women. The broad objective of this project is to further our understanding of the health consequences of moderate intensity resistance exercise training for pregnant women. Moderate intensity aerobic exercise has been found to be safe and healthful for pregnant women, but little is known about the health effects of moderate intensity resistance exercise. Accordingly, the specific aims of the proposed research are to test the hypotheses that: (1) 16 weeks of moderate intensity resistance exercise training of the legs, back, abdominal and truck musculature performed twice weekly during the second and third trimesters will significantly attenuate back pain; (2) the resistance exercise training program will significantly attenuate pregnancy-induced loss of back function; and (3) the resistance exercise training program will significantly improve pain-related quality of life. To accomplish these goals 180 healthy pregnant women with back pain will be recruited to begin participating during the first two months of their second trimester. The participants will be randomized to perform sixteen weeks of either a supervised twice weekly, moderate intensity resistance exercise program, a pregnancy-related education program (i.e., placebo condition), or a waiting list control condition. Valid measures of back pain, back function and pain-related quality of life will be used to test the outcome of the randomized controlled trial. There is an urgent need to learn more about the health consequences of resistance exercise training among pregnant women in part because women increasingly are performing resistance exercise during their pregnancy. Unfortunately, at the present time there is a lack of scientific information available to nurses, physicians and other health professionals concerning the health outcomes associated with moderate intensity resistance exercise training among pregnant women.

描述（由申请人提供）：背部疼痛是孕妇常见的健康问题。背部疼痛会产生严重的不良后果，包括生活质量下降，工作和生活能力下降。鉴于许多妇女在怀孕期间宁愿避免服用药物，考虑使用非药物方法来减少背部疼痛和提高生活质量是有用的。中等强度的阻力运动训练为减轻孕妇背部疼痛提供了一种看似有效的方法。该项目的总体目标是进一步了解中等强度的抗阻运动训练对孕妇健康的影响。人们已经发现，中等强度的有氧运动对孕妇是安全和健康的，但人们对中等强度的阻力运动对健康的影响知之甚少。因此，本研究的具体目的是验证以下假设：(1)在妊娠中期和晚期，每周两次进行16周的中等强度的腿部、背部、腹部和卡车肌肉的阻力运动训练将显著减轻背痛；(2)抗阻运动训练方案能显著减轻妊娠所致的背部功能丧失；(3)抗阻运动训练方案能显著改善疼痛相关的生活质量。为了实现这些目标，将招募180名患有背痛的健康孕妇在妊娠中期的前两个月开始参与研究。参与者将被随机分配进行为期16周的监督，每周两次，中等强度的阻力运动计划，怀孕相关的教育计划（即安慰剂条件），或等待名单控制条件。有效的背部疼痛、背部功能和与疼痛相关的生活质量测量将用于测试随机对照试验的结果。迫切需要更多地了解孕妇抗阻运动训练对健康的影响，部分原因是越来越多的妇女在怀孕期间进行抗阻运动。不幸的是，目前护士、医生和其他卫生专业人员缺乏有关孕妇中等强度抗阻力运动训练的健康结果的科学信息。
