| 目的：探讨长期中等强度运动对健康女青年智力的影响。方法：选取2021年6月~2022年12月首都医科大学康复专业2019级女学生和中国康复研究中心进修的年轻女治疗师共60人作为研究对象，按照运动指数将其分成久坐组与运动组（中等强度运动组）。2组均进行中国修订韦氏智力量表（第四版）测试、持续操作性测试；采集受试者任务态的fNIRS前额叶22个通道氧合血红蛋白和脱氧血红蛋白浓度变化值，去除大脑纵裂通道4和19，双侧各取10个通道的平均重心值，同时记录持续性操作测试的正确率、命中率和平均反应时长。结果：韦氏智力量表结果显示运动组的操作智商显著高于久坐组（P<0.01）；而且2组间的言语智商和总智商的差异均存在统计学意义（P<0.05）；在木块试验、图片拼凑两个分测验中，运动组表现要优于久坐组（P<0.05）。持续性操作测试组间的正确率、命中率均无统计学差异。但相较于久坐组而言，运动组的正确率和命中率更高，反应时长更短。功能性近红外光谱显示左侧前额叶氧合血红蛋白变化的重心值运动组低于久坐组（P<0.01）。结论：运动可通过改善大脑左前额叶的激活水平，进一步提高健康女青年智力水平。但运动功能对于持续注意力水平改善程度仍需要进一步探讨。 |

| Objective: To explore the effect of long-term moderate exercise on intelligence of healthy young women. Methods: A total of 60 young female therapists who were enrolled in the 2019 rehabilitation major of Capital Medical University from June 2021 to December 2022 and studied in the China Rehabilitation Research Center were selected as the study subjects. They were divided into sedentary group and exercise group (moderate exercise group) according to the exercise index. Both groups were tested with the revised Wechsler Intelligence Scale (the fourth edition) and the continuous operational test. The concentration changes of oxygenated hemoglobin and deoxygenated hemoglobin in 22 functional near-infrared spectroscopy (fNIRS) channels in the prefrontal lobe of the subjects in task state were collected, the longitudinal fissure channels 4 and 19 of the brain were removed, and the average values of 10 channels on both sides were taken. Meanwhile, the correct rate, hit rate and average reaction time of the task were recorded. Results: The Wechsler Intelligence Scale showed that the operational intelligent quotient (IQ) of the exercise group was significantly higher than that of the sedentary group (P<0.01). Moreover, there were statistically significant differences in verbal IQ and total IQ between the two groups (P<0.05). In the two sub-tests, the exercise group performed better than the sedentary group, and there was a statistical difference between the two groups (P<0.05). There was no statistically significant difference in the accuracy rate, hit rate between CPT groups. However, the accuracy rate and hit rate of the exercise group were higher, and the reaction time was shorter in the exercise group than in the sedentary group. Functional near-infrared spectroscopy showed that the Central Value of changes in oxygenated hemoglobin in the left prefrontal lobe was lower in the exercise group than in the sedentary group (P<0.01).Conclusion: Exercise can further improve the intelligence level of healthy young women by improving the activation level of the left prefrontal lobe of the brain. However, the improvement of motor function on the level of sustained attention still needs further study. |
