Sleep complaints are one of the most common health problems facing middle- and older-aged adults, resulting in significant medical utilization along with reduced psychological well-being and quality of life. In light of the cost and potential adverse effects accompanying long-term use of sedative-hypnotic medications, the development of alternative strategies for improving sleep in older populations is strongly indicated. One such potentially efficacious strategy is regular physical activity, a health behavior that typically diminishes with age. Although results from the first randomized, controlled trial evaluating the effects of increases in physical activity on sleep quality among healthy older adults with initial sleep complaints were promising, the study suffered from several methodological constraints that require further investigation. The objectives of this study are to: (1) determine the initial (6 months) and longer-term (12 months) effectiveness of a moderate-intensity physical activity program in promoting significant improvements in subjectively and objectively measured sleep quality in older adults with moderate sleep complaints; (2) evaluate the efficacy of the physical activity regimen for promoting initial and longer-term changes in a broad array of psychological and physical functioning (quality of life) variables; and (3) investigate a selected set of potential mediators and moderators of the physical activity/sleep relationship. The study design is a one-year randomized trial in which 120 sedentary women and men ages 55 years and older with moderate sleep complaints will be randomly assigned to one of two conditions: moderate-intensity physical activity training, or an attention-control (health education) condition. Both programs are designed to enhance long-term participation. Data will be collected at baseline and at 6 and 12 months using age-relevant physical performance and physical activity instruments, self-rated and objective sleep quality measures collected in the natural environment, and a comprehensive set of psychological and physical functioning scales. Our primary hypotheses are that subjects assigned to physical activity training will demonstrate significant increases in sleep quality along with other quality of life measures, maintained through 12 months, relative to the non-exercise control condition. This study will contribute important information with respect to the development of effective nonpharmacologic approaches to improving sleep quality among the large segment of healthy, community-dwelling older adults with sleep complaints.

睡眠问题是中老年人面临的最常见的健康问题之一，导致沿着的心理健康和生活质量下降。 鉴于长期使用镇静催眠药物的成本和潜在的不良反应，强烈建议开发替代策略来改善老年人群的睡眠。 其中一个潜在的有效策略是定期的身体活动，这种健康行为通常会随着年龄的增长而减少。虽然第一个随机对照试验的结果是有希望的，但该研究受到了一些方法上的限制，需要进一步研究。本研究的目的是：（1）确定初始（6个月）和更长期（12个月）中等强度体力活动计划在促进中度睡眠投诉老年人主观和客观测量的睡眠质量显著改善方面的有效性;（2）评估身体活动方案促进广泛的心理和身体功能的初始和长期变化的功效（生活质量）变量;以及（3）调查一组选定的身体活动/睡眠关系的潜在调解者和调节者。 研究设计是一项为期一年的随机试验，其中120名年龄在55岁及以上的久坐不动的女性和男性，有中度睡眠投诉，将被随机分配到两个条件之一：中等强度的体力活动训练，或注意力控制（健康教育）条件。 这两项计划都旨在加强长期参与。 将使用年龄相关的身体表现和身体活动工具、在自然环境中收集的自我评定和客观睡眠质量测量以及一套全面的心理和身体功能量表，在基线和6个月和12个月时收集数据。 我们的主要假设是，相对于非运动控制条件，分配到体力活动训练的受试者将表现出睡眠质量沿着其他生活质量指标的显著增加，并维持12个月。 这项研究将提供重要的信息，有效的非药物方法，以改善睡眠质量的大部分健康，居住在社区的老年人与睡眠投诉的发展。
