To explore the effects of acute high-intensity interval rope skipping exercise and acute moderate-intensity continuous rope skipping exercise on cognitive function in 9-10-year-old children, this study aims to inform the selection of appropriate jump rope methods for cognitive training in physical activities. A total of 60 students from two classes of fourth grade in a primary school were selected as research subjects. After matching according to gender, they were randomly divided into HIIT group, MICT group and control group. The Digit Span Test (DST), Attention Network Test (ANT) and Stroop Color Word Test were conducted three days before the intervention and 5 min after the intervention. During the intervention, the HIIT group performed a high-intensity intermittent rope skipping exercise (required fast jumping with feet together, practice for 1 min and rest for 1 min, jump continuously for 5 groups, and the exercise intensity is ≥ 85% of the maximum heart rate), while the MICT group performed a moderate-intensity continuous rope skipping exercise (required to medium jumping with feet together, jump continuously for 5 min, and the exercise intensity is 60-80% of the maximum heart rate), and the control group rests in place. After the intervention, both HIIT and MICT groups showed increased DST total scores, improved executive control network efficiency, and faster inhibitory control response speeds, with no significant changes in accuracy. The HIIT group also exhibited increased orienting network efficiency and no significant changes in accuracy. Acute rope skipping exercises using HIIT and MICT methods can improve the working memory, executive control network efficiency and inhibitory control ability of children aged 9-10 years old. Additionally, conducting acute rope skipping exercises using HIIT method can also enhance their orienting network efficiency.
为探讨急性高强度间歇跳绳运动和急性中等强度连续跳绳运动对 9-10 岁儿童认知功能的影响，本研究旨在为体育活动中认知训练选择合适的跳绳方法提供依据。选取某小学四年级两个班的 60 名学生作为研究对象，按性别匹配后随机分为 HIIT 组、MICT 组和对照组。在干预前 3 天和干预后 5 分钟进行数字跨度测试（DST）、注意网络测试（ANT）和斯特鲁普色词测验。干预期间，HIIT 组进行高强度间歇跳绳运动（要求双脚并拢快速跳跃，练习 1 分钟，休息 1 分钟，连续跳 5 组，运动强度≥最大心率的 85%），MICT 组进行中等强度连续跳绳运动（要求双脚并拢中速跳跃，连续跳跃 5 分钟，运动强度为最大心率的 60-80%），对照组原地休息。干预后，HIIT 组和 MICT 组的 DST 总分均增加，执行控制网络效率提高，抑制控制反应速度加快，准确性无显著变化。HIIT 组定向网络效率也有所提高，准确性无显著变化。急性 HIIT 和 MICT 跳绳运动均可提高 9-10 岁儿童的工作记忆、执行控制网络效率和抑制控制能力，急性 HIIT 跳绳运动还可提高定向网络效率。
