目的：为了同时研究急性运动强度和自由生活的体力活动和久坐不动的行为对认知功能的影响，在年轻，健康的adults.Patients和方法：使用一个平衡，交叉，随机对照设计，87名年轻人（平均年龄，21.4岁）完成了各种认知评估，并没有一个急性回合的运动之前的评估。参与者被随机分为4组，以完成30分钟的急性运动：对照组（不运动），轻度强度（预测最大心率[HRmax]的40%-50%），中度强度（预测HRmax的51%-70%）或剧烈强度（预测HRmax的71%-85%）。主观和客观确定（加速度）的身体活动和久坐行为进行了评估，以检查这些自由生活行为和认知功能之间的关联。研究持续时间为2013年8月26日至2014年9月11日。结果：30分钟急性中等强度运动后的集中相关认知（平均+/- SD特征匹配测试得分）（145.1 +/- 26.9）显著高于无运动的认知评估（121.3 +/- 19.2; P = 0.004）。此外，由意志力决定的久坐行为与视觉注意力和任务转换（连线测试A评分）呈负相关（β = -0.23; P = .04）。最后，估计心肺健康（最大耗氧量）与推理相关的认知功能正相关（Odd One Out测试）（β = 0.49; P = 0.05）;当将每周任务分钟数的代谢当量添加到该模型中时，结果不显著结论：这些发现为急性中等强度运动、久坐行为和心肺适能与年轻健康成人的执行功能相关认知功能相关提供了一些支持。(C)2015年马约医学教育和研究基金会
Objective: To simultaneously examine the effects of acute exercise intensity and free-living physical activity and sedentary behavior on cognitive function in young, healthy adults.Patients and Methods: Using a counterbalanced, crossover, randomized controlled design, 87 young adults (mean age, 21.4 years) completed various cognitive assessments with and without an acute bout of exercise preceding the assessment. Participants were randomized into 1 of 4 groups to complete a 30-minute bout of acute exercise: control (no exercise), light intensity (40%-50% of predicted maximum heart rate [HRmax]), moderate intensity (51%-70% of predicted HRmax), or vigorous intensity (71%-85% of predicted HRmax). Subjectively and objectively determined (accelerometry) physical activity and sedentary behavior were assessed to examine the association between these free-living behaviors and cognitive function. The study duration was August 26, 2013, to September 11, 2014.Results: Concentration-related cognition (mean +/- SD Feature Match test score) was significantly higher after a 30-minute acute bout of moderate-intensity exercise (145.1 +/- 26.9) compared with cognitive assessment without exercise (121.3 +/- 19.2; P = .004). Furthermore, questionnaire-determined sedentary behavior was inversely associated with visual attention and task switching (Trail Making Test A score) (beta = -0.23; P = .04). Last, estimated cardiorespiratory fitness (volume of maximum oxygen consumption) was positively associated with reasoning-related cognitive function (Odd One Out test score) (beta = 0.49; P = .05); when adding metabolic equivalent of task minutes per week to this model, the results were not significant (beta = 0.47; P = .07).Conclusion: These findings provide some support for acute moderate-intensity exercise, sedentary behavior, and cardiorespiratory fitness being associated with executive functioning-related cognitive function in young, healthy adults.
