Project Summary The average age of the U.S. population is rapidly increasing and with it the prevalence of age-associated cognitive decline. Furthermore, the risk for age-associated cognitive decline may disproportionately affect many historically underrepresented groups. Regular physical activity (PA) is associated with lower risk for cognitive decline, but many people struggle to maintain PA over the long term. Goal setting presents one promising avenue to facilitate PA maintenance and has strong public health significance. Likewise, exercise intensity may further this aim as challenging goals for higher intensity PA may provide the most robust PA maintenance. Importantly, however, most existing research on goal setting, exercise intensity, and theory- based exercise interventions overall has been generated among high SES, low diversity samples, and the field has largely neglected this disparity, with recent reviews and meta-analyses failing to even report racial, ethnic, or socioeconomic demographic factors. While systems of oppression and structural racism undoubtedly influence disparities in health behavior and outcomes, it is also possible that existing individual-level theory- based interventions are not culturally appropriate for many communities, such as African Americans and Black immigrants (i.e., the Black community). In this application, we will take a community engaged research approach to tailor and test a theory-based intervention promoting adherence to recommended levels of PA in the Black community using the technique of person-centered goal setting. We will determine whether prescriptions of different PA intensities moderate the effectiveness of these goal-setting approaches and test the theoretical mediators associated with the effectiveness of these interventions on behavioral adherence and healthy changes in biomarkers associated with cognitive decline. Therefore, the overarching goals of this project are to take a community engaged research approach to 1) tailor a theory-based goal-setting exercise intervention in the Denver metropolitan area Black community (R61) and 2) utilize the Operating Conditions Framework to test the efficacy of the intervention for PA adherence, weekly volume of exercise, and changes in biomarkers associated with cognitive decline (R33). These objectives will be met through collaboration with our community partner The Gyedi Project to focus on and fully engage the Black community in the Denver metropolitan area in the research process.

项目摘要 美国人口的平均年龄正在迅速增长，与年龄相关的疾病的流行率也在迅速上升。 认知能力下降此外，与年龄相关的认知能力下降的风险可能不成比例地影响 许多历史上代表性不足的群体。定期的体力活动（PA）与较低的风险有关， 认知能力下降，但许多人难以长期维持PA。目标设定提出了一个 有希望的途径，促进PA的维护，具有很强的公共卫生意义。同样，锻炼 强度可以进一步实现这一目标，因为较高强度PA的挑战性目标可以提供最稳健的PA 上维护然而，重要的是，大多数关于目标设定、运动强度和理论的现有研究- 基于运动的干预措施总体上是在高社会经济地位、低多样性样本和实地中产生的。 在很大程度上忽略了这种差异，最近的综述和荟萃分析甚至没有报告种族，民族， 或社会经济人口因素。虽然压迫和结构性种族主义的制度无疑 影响健康行为和结果的差异，也可能是现有的个人水平的理论- 基于文化的干预措施不适合许多社区，如非洲裔美国人和黑人 移民（即，黑人社区）。在这个应用程序中，我们将采取社区参与的研究 一种方法来定制和测试一个基于理论的干预，促进遵守推荐的PA水平， 黑人社区使用以人为本的目标设定技术。我们将决定 不同PA强度的处方调节这些目标设定方法的有效性，并测试 与这些干预措施对行为依从性的有效性相关的理论中介， 与认知能力下降相关的生物标志物的健康变化。因此，本项目的总体目标 项目是采取社区参与的研究方法，1）定制基于理论的目标设定 运动干预在丹佛大都市区黑人社区（R61）和2）利用 操作条件框架，用于测试PA依从性干预措施的有效性，每周一次 运动量，以及与认知能力下降相关的生物标志物的变化（R33）。这些 目标将通过与我们的社区合作伙伴Gyedi项目合作来实现， 让丹佛大都会区的黑人社区参与研究过程。
