项目摘要

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）：有氧和抵抗训练的组合在维持体育活动（PA）方面具有独特的好处。但是，尚不清楚用于结合老年人这两种培训模式的最佳培训计划。这项研究以当前和过去的研究为基础，表明训练引起的有氧健身，肌肉力量和PA的易感性对于维持积极的生活方式，有利的身体成分和高骨密度很重要。传统上，3 d/wk的组合训练被认为是最佳的，而最近的研究表明1 d/wk的组合训练可能会产生与更频繁的训练相似的适应。但是，我们以前正在进行的研究表明，1 d/wk的有氧和耐药性训练（C1）可能不足以诱导最佳适应性，而3 d/wk组合训练（C3）可能过于频繁地刺激老年人。这项研究将使我们能够比较C1，2 d/wk合并训练（C2）和C3对健身，身体组成，PA，PA的易感性和总自由生活能量消耗（TEE）的影响。我们假设C2会导致肌肉大小，骨密度，强度，有氧能力，功率，PA，PA和TEE的易感性更大。还将检查循环的细胞因子和与长期过度应力有关的心理情绪状态。目的：我们将检查16和32周后，我们将检查循环细胞因子，情绪状态，肌肉大小，有氧能力，力量，PA，PA和TEE的易感性，易感性，功率，易感性。设计：我们将评估78岁（> 60年）的黑人和白人妇女在16周之前，经过32周后，在C1，C2或C3组中匹配了年龄，种族和BMI。妇女将在一般临床研究中心评估代谢参数。意义：这项研究应深入了解联合训练频率对提高健身，易于pa和维持高发球的影响。这些信息对于我们对改善福祉，生活质量和老龄化人口独立的方式的理解至关重要。
