SWEET-SENIOR WOMEN ENJOYING EXERCISE TOGETHER

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。有氧和阻力相结合的训练对保持体力活动(PA)有独特的好处。然而，在老年人中结合这两种训练模式的最佳训练计划尚不清楚。传统上，3d/wk组合训练被认为是最佳的，而最近的研究表明，1d/wk组合训练可能会产生与更频繁的训练类似的适应能力。然而，我们先前和正在进行的研究表明，1d/wk的有氧和阻力联合训练(C1)可能不足以诱导最佳适应，而3d/wk联合训练(C3)对老年人来说可能太频繁了。这项研究将使我们能够比较C1、2d/wk组合训练(C2)和C3训练对身体素质、身体成分、PA、PA的舒适度和总自由生活能量消耗(TEE)的影响。我们假设C2将导致肌肉大小、骨密度、力量、有氧能力、力量、PA、PA和TEE的舒适度比C2或C3更大的增加。目的：我们将检测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、力量、PA、PA和TEE的舒适度的变化。设计：我们将年龄、种族和体重指数匹配的78名黑人和白人女性在16周训练前、16周后和32周后评估为C1、C2或C3组。意义：这项研究应该为综合训练频率对提高体能、PA的舒适度和保持高发球区的效果提供洞察。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. 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. 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. 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 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. 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.
