Physical exercise has the potential to affect cognitive function, but most evidence to date focuses on cognitive effects of fitness training. Cognitive exercise also may influence cognitive function, but many cognitive training paradigms have failed to provide carry-over to daily cognitive function. Video games provide a broader, more contextual approach to cognitive training that may induce cognitive gains and have carry over to daily function. Most video games do not involve physical exercise, but some novel forms of interactive video games combine physical activity and cognitive challenge.
METHODS/DESIGN: This paper describes a randomized clinical trial in 168 postmenopausal sedentary overweight women that compares an interactive video dance game with brisk walking and delayed entry controls. The primary endpoint is adherence to activity at six months. Additional endpoints include aspects of physical and mental health. We focus this report primarily on the rationale and plans for assessment of multiple cognitive functions.
This randomized clinical trial may provide new information about the cognitive effects of interactive videodance. It is also the first trial to examine physical and cognitive effects in older women. Interactive video games may offer novel strategies to promote physical activity and health across the life span.The study is IRB approved and the number is: PRO08080012ClinicalTrials.gov Identifier: NCT01443455.
体育锻炼有可能影响认知功能，但迄今为止，大多数证据都集中在健身训练对认知的影响上。认知锻炼也可能影响认知功能，但许多认知训练模式未能将其效果延续到日常认知功能上。视频游戏提供了更广泛、更具背景的认知训练方法，可能会引起认知上的提高，并将其效果延续到日常功能上。大多数视频游戏不涉及体育锻炼，但一些新型的互动视频游戏将身体活动和认知挑战结合在一起。
方法/设计：本文描述了一项针对 168 名绝经后久坐超重女性的随机临床试验，比较了互动视频舞蹈游戏与快走和延迟进入对照组。主要终点是六个月时的活动依从性。其他终点包括身体和心理健康的各个方面。我们主要关注本报告中对多种认知功能进行评估的基本原理和计划。
这项随机临床试验可能提供有关互动视频游戏对认知影响的新信息。这也是第一个研究老年人身体和认知影响的试验。互动视频游戏可能为促进整个生命周期的身体活动和健康提供新的策略。该研究已获得机构审查委员会的批准，编号为：PRO08080012。ClinicalTrials.gov 标识符：NCT01443455。
