Cognitive Regulation Training and Exercise (CORTEX)-II with Middle-aged Adults

项目摘要 在整个生命周期中，体力活动率都在下降。相对于其他年龄段，全国范围内 对身体活动的估计在中年人群中是最低的。每周平均健身使用量 美国的设施也远低于推荐的体力活动水平。此外，在 在开始有组织的锻炼计划的前6个月，辍学率大约是 50%。“助推策略”主要在运动干预中实施，以 提高对学习方案的遵从性，尚未确定是否在 开始参加锻炼计划可以减少消耗并增加长期的 在有限的专业指导下坚持和参与体育活动。证据 提示一般认知训练和针对运动相关认知的训练 加工具有提高自我效能和自我调节策略的潜力，并且 归根结底，锻炼行为的维持。在过去的十年里，活跃的视频游戏(努力游戏) 对老龄化人口采取了干预措施，使锻炼变得更愉快和 让大脑为行动做好准备。活动视频游戏已在中心内成功交付- 和基于家庭的干预措施，并在行动能力、认知能力方面产生了积极影响 功能、心理社会结果和体力活动行为。这次双打的目的是- 随机、盲法对照研究比较大脑皮层(认知调节训练 和运动)，这是一个多方面的、一般的和针对运动的认知训练计划- 包括20小时的积极和传统的计算机化认知培训，通过 培训中心和家里--对涉及健康和健康的注意力控制状况 信息性视频。更具体地说，认知训练组将强调双重任务 能力，记忆力，视觉-空间处理，以及自我锻炼的启动和自我 确定性训练。我们假设为期一个月的认知训练计划将增强 认知和相关的自我调节功能和自我效能感，进而增加 在为期12个月的有氧和耐力锻炼计划中坚持和参与锻炼 在当地的一家健身中心。我们还期待在认知和认知方面有更积极的改善 大脑皮质状况下参与者的心理社会功能与 视频控制条件在认知助推器训练后立即进行，并跨越时间。

Project Summary Physical activity rates decrease across the lifespan. Relative to other age groups, nationwide estimates of physical activity are among the lowest in midlife. Average weekly usage of fitness facilities in the U.S. is also well below recommended levels of physical activity. Moreover, within the first 6 months of initiating a structured exercise program, dropout rates are approximately 50 percent. “Booster strategies” have mainly been implemented within exercise interventions to increase compliance to study protocols, and it has yet to be determined whether training at the onset of enrollment in an exercise program can reduce attrition and increase long-term adherence and engagement in physical activity with limited professional guidance. Evidence suggests that general cognitive training and training specific to exercise- related cognitive processing has the potential to increase self-efficacy and self-regulatory strategies, and ultimately, exercise behavior maintenance. In the last decade, active videogame (exergaming) interventions have been used with aging populations to make exercise more enjoyable and prepare the brain for action. Active videogames have been successfully delivered within center- and home-based interventions and have yielded positive effects on mobility, cognitive functioning, psychosocial outcomes, and physical activity behavior. The purpose of this double- blinded, randomized controlled study is to compare CORTEX (Cognitive Regulation Training and Exercise), a multi-faceted, general and exercise-specific cognitive training program— involving 20 hours of active and traditional computerized cognitive training, delivered via a training center and at home—to an attention-control condition involving health and wellness informational videos. More specifically, the cognitive training group will emphasize dual-task abilities, memory, visual-spatial processing, as well as self-as-exerciser priming and self- certainty training. We hypothesize that a month-long cognitive training program will enhance cognitive and related self-regulatory functioning and self-efficacy and in turn, increase exercise adherence and engagement within a 12-month aerobic and resistive exercise program at a local fitness facility. We also expect more positive improvements in cognitive and psychosocial functioning among participants in the CORTEX condition as compared to the Video Control condition immediately following the cognitive booster training, and across time.
