This study aimed to investigate the effects of aerobic exercise on reactive inhibitory control in college students with internet addiction, examining both behavioral and electrophysiological changes over time.
A longitudinal study design was adopted, involving 48 male college students with internet addiction who were randomly assigned to either a control group or an experimental group. Participants in the experimental group engaged in 40 min aerobic cycling sessions three times per week for 12 weeks, while the control group maintained their usual physical activity levels without any intervention. A 3 × 2 × 3 mixed-factorial design was utilized, incorporating three time points (pre-experiment, 6 and 12 weeks), two groups (control and experimental), and three electrode sites (Fz, F3, F4). This design enabled the examination of the effects of aerobic exercise on reactive inhibitory control and its temporal dynamics in college students with internet addiction.
A significant main effect of group was observed. Specifically, the experimental group demonstrated a significantly higher Nogo accuracy rate compared to the control group at both the mid-test ( < 0.01) and post-test ( < 0.001). Within the experimental group, the Nogo accuracy rate at the mid-test and post-test was significantly higher than at the pre-test ( < 0.001), with the post-test accuracy rate also significantly higher than the mid-test (P < 0.05). Time-frequency analysis revealed that, under the Nogo task, the energy values in the beta frequency band during the early (100-500 ms) and late (600-750 ms) time windows were significantly higher at the mid-test and post-test compared to the pre-test ( < 0.05), with the post-test values significantly exceeding those at the mid-test ( < 0.05).
(1) Moderate-intensity aerobic exercise significantly improves reactive inhibitory control in college students with internet addiction, with the magnitude of improvement increasing over the duration of the intervention. (2) Increased beta band energy during the early (100-500 ms) and late (600-750 ms) time windows serve as a key neurophysiological indicator of this enhancement.
本研究旨在探讨有氧运动对网络成瘾大学生反应抑制控制的影响，考察行为和电生理随时间的变化。
采用纵向研究设计，纳入48名网络成瘾男性大学生，随机分为对照组和实验组。实验组参与者每周进行3次40分钟的有氧骑行，共12周，而对照组保持其平常的身体活动水平，不进行任何干预。采用3×2×3混合因子设计，包括三个时间点（实验前、6周和12周）、两组（对照组和实验组）和三个电极部位（Fz、F3、F4）。该设计能够考察有氧运动对网络成瘾大学生反应抑制控制及其时间动态的影响。
观察到显著的组间主效应。具体而言，在中期测试（<0.01）和后期测试（<0.001）时，实验组的Nogo准确率均显著高于对照组。在实验组内，中期测试和后期测试时的Nogo准确率显著高于实验前（<0.001），后期测试准确率也显著高于中期测试（P<0.05）。时频分析显示，在Nogo任务下，与实验前相比，中期测试和后期测试时早期（100 - 500毫秒）和晚期（600 - 750毫秒）时间窗内β频段的能量值显著更高（<0.05），后期测试值显著超过中期测试值（<0.05）。
（1）中等强度有氧运动显著改善网络成瘾大学生的反应抑制控制，且改善程度随干预持续时间增加。（2）早期（100 - 500毫秒）和晚期（600 - 750毫秒）时间窗内β频段能量增加是这种增强的关键神经生理指标。
