Associations between daily physical activity (PA) and executive functioning have rarely been investigated among young adults. This study examined these associations among 162 university students (74 females and 88 males; mean age = 19.0, SD = 1.1 years). We measured PA objectively, using hip-mounted accelerometers, and assessed executive functioning in a task-switching paradigm. Anthropometrics measurements were gathered using standardized procedures. Through linear regression modeling, we found moderate-to-vigorous physical activity (β = -0.19, 95% CI = [-0.35, -0.03], p = .02) and light physical activity (β = -0.17, 95% CI = [-0.34, -0.01], p = .04) to be associated with smaller global reaction time switch costs. Total PA was not associated with task-switching performance, and there were no statistically significant associations between PA indicators and local switch costs. As both moderate-to-vigorous and light physical activities were associated with better executive function in young adults, there can be important cognitive benefits to remaining physically active.
在年轻人中，日常身体活动（PA）与执行功能之间的关联鲜有研究。本研究在162名大学生（74名女性和88名男性；平均年龄 = 19.0岁，标准差 = 1.1岁）中考察了这些关联。我们使用佩戴在髋部的加速度计客观测量身体活动，并在任务转换范式中评估执行功能。使用标准化程序收集人体测量数据。通过线性回归模型，我们发现中等到剧烈身体活动（β = -0.19，95%置信区间 = [-0.35, -0.03]，p = .02）和轻度身体活动（β = -0.17，95%置信区间 = [-0.34, -0.01]，p = .04）与较小的全局反应时间切换成本相关。总身体活动与任务转换表现无关，且身体活动指标与局部切换成本之间无统计学上的显著关联。由于中等到剧烈身体活动和轻度身体活动均与年轻人更好的执行功能相关，保持身体活跃可能会带来重要的认知益处。
