The aim of this investigation was to examine the influence of different types of exercise exertion on primary school children's working memory (WM).
Participants (N = 71, 9.4 yr, 39 girls) were randomly assigned to a cardiovascular exercise (CE), a motor exercise (ME), or a control group (CON). They underwent a letter digit span task (WM) before and after an intervention period that involved 10 wk of an additional afterschool exercise regimen, which took place three times a week for 45 min. Students in the control group participated in assisted homework sessions.
WM performance of the 9- to 10-yr-old children benefited from both the cardiovascular and the motor exercise programs, but not from the control condition. The increase in WM performance was significantly larger for children in the ME compared with the CE or CON.
These findings add to the knowledge base relating different types of exercise and WM. Besides the efficiency of cardiovascular exercise training, a special motor-demanding intervention seems to be a beneficial strategy to improve WM in preadolescent children.
本研究旨在探讨不同类型的运动对小学生工作记忆（WM）的影响。
参与者（N = 71，9.4岁，39名女孩）被随机分配到心血管运动组（CE）、体育锻炼组（ME）或对照组（CON）。在为期10周的课外锻炼干预期前后，他们接受了字母数字广度任务（WM）测试，干预期每周进行三次，每次45分钟。对照组的学生参加辅导作业课程。
9至10岁儿童的工作记忆表现受益于心血管运动和体育锻炼计划，但对照组则不然。与CE组或CON组相比，ME组儿童的工作记忆表现提升显著更大。
这些发现增加了与不同类型运动和工作记忆相关的知识库。除了心血管运动训练的效果外，一项特殊的高运动需求干预似乎是改善青春期前儿童工作记忆的有益策略。
