The objective of this experiment was to evaluate the effects of acute exercise on memory interference and determine if this potential relationship is moderated by sex. A randomized controlled experiment was conducted (N = 40), involving young adult males (n = 20) and females (n = 20) completing two counterbalanced visits (exercise and no exercise). The exercise visit involved an acute (15 min), moderate-intensity bout of treadmill exercise, while the control visit involved a time-matched seated task. Memory interference, including both proactive interference and retroactive interference, involved the completion of a multi-trial memory task. In a factorial ANOVA with the outcome being List B, there was a main effect for condition (F(1,38) = 5.75, P = 0.02, n = 0.13), but there was no main effect for sex (F(1,38) = 1.39, P = 0.24, n = 0.04) or sex by condition interaction (F(1,38) = 1.44, P = 0.23, n = 0.04). In conclusion, acute moderate-intensity exercise was effective in attenuating a proactive memory interference effect. This effect was not moderated by biological sex.
本实验旨在评估急性运动对记忆干扰的影响，并确定这种潜在的关系是否受到性别的调节。进行了一项随机对照实验（N=40），涉及 20 名年轻成年男性和 20 名女性，他们完成了两次平衡的访问（运动和不运动）。运动访问包括一次急性（15 分钟）、中等强度的跑步机运动，而对照访问则涉及时间匹配的坐姿任务。记忆干扰，包括前摄干扰和后摄干扰，涉及到多试记忆任务的完成。在以 List B 为结果的因子方差分析中，条件有一个主要影响（F(1,38)=5.75, P=0.02, n=0.13），但性别没有主要影响（F(1,38)=1.39, P=0.24, n=0.04）或性别与条件的相互作用（F(1,38)=1.44, P=0.23, n=0.04）。总之，急性中等强度运动有效地减弱了前摄记忆干扰效应。这种效应不受生物性别调节。
