DESCRIPTION (provided by applicant): Combined aerobic and resistance training have unique benefits for maintaining a physical activity (PA). However, the optimal training program for combining these two modes of training in older adults is unknown. This study builds on current and past studies showing that training induced gains in aerobic fitness, muscle strength, and ease of PA are important for maintaining an active lifestyle, a favorable body composition, and high bone density. Traditionally 3 d/wk combined training has been felt to be optimal while recent studies suggest 1 d/wk combined training may create similar adaptations as more frequent training. However, our previous and ongoing studies suggest that 1 d/wk combined aerobic and resistance training (C1) may be insufficient stimulus to induce optimal adaptations and that 3 d/wk combined training (C3) may be too frequent a stimulus for older adults. This study will enable us to compare the effects of C1, 2 d/wk combined training (C2), and C3 on fitness, body composition, ease of PA, PA, and total free-living energy expenditure (TEE). We hypothesize that C2 will result in a larger increase in muscle size, bone density, strength, aerobic capacity, power, ease of PA, PA, and TEE than either C1 or C3. Circulating cytokines and psychological mood states linked to chronic overstress will also be examined. Objectives: We will examine changes in circulating cytokines, mood states, muscle size, bone density, aerobic capacity, strength, power, ease of PA, PA, and TEE following 16 and 32 wks training. Design: We will to evaluate 78 (>60 yrs) Black and White women matched for age, race, and BMI into C1, C2, or C3 groups prior to, after 16, and after 32 wks training. Women will undergo evaluation of metabolic parameters in a General Clinical Research Center. Significance: This study should provide insight into the effects combined training frequency has on improving fitness, ease of PA, and maintenance of a high TEE. Such information is critical to our understanding of ways to improve well being, quality of life, and independence of an aging population.

描述（由申请人提供）：有氧运动和阻力训练相结合对于维持体力活动 (PA) 具有独特的益处。然而，对于老年人来说，结合这两种训练模式的最佳训练计划尚不清楚。这项研究建立在当前和过去的研究基础上，这些研究表明，训练引起的有氧健身、肌肉力量和体力活动轻松度的提高对于保持积极的生活方式、良好的身体成分和高骨密度非常重要。传统上 3 天/周的联合训练被认为是最佳的，而最近的研究表明 1 天/周的联合训练可能会产生与更频繁的训练类似的适应。然而，我们之前和正在进行的研究表明，对于老年人来说，每周 1 天的有氧运动和阻力训练 (C1) 可能不足以刺激产生最佳适应，而每周 3 天的联合训练 (C3) 可能过于频繁。这项研究将使我们能够比较 C1、2 天/周组合训练 (C2) 和 C3 对健身、身体成分、PA 轻松度、PA 和总自由生活能量消耗 (TEE) 的影响。我们假设，与 C1 或 C3 相比，C2 会导致肌肉大小、骨密度、力量、有氧能力、爆发力、PA、PA 和 TEE 的容易程度有更大的增加。还将检查与慢性过度压力相关的循环细胞因子和心理情绪状态。目标：我们将检查 16 周和 32 周训练后循环细胞因子、情绪状态、肌肉大小、骨密度、有氧能力、力量、功率、PA、PA 和 TEE 的易用性的变化。设计：我们将在 16 周训练前、16 周训练后和 32 周训练后对 78 名（> 60 岁）黑人和白人女性进行评估，这些女性的年龄、种族和 BMI 相匹配，分为 C1、C2 或 C3 组。女性将在综合临床研究中心接受代谢参数评估。意义：这项研究应该深入了解组合训练频率对改善体能、轻松 PA 和维持高 TEE 的影响。这些信息对于我们了解改善老龄化人口的福祉、生活质量和独立性的方法至关重要。
