This study aimed to investigate the differences in cerebral cortex activation during a static balance task between sporting and non-sporting groups using functional near-infrared spectroscopy (fNIRS). The Clinical Test of Sensory Interaction on Balance (CTSIB) was employed to assess balance performance in both groups.
The study involved 70 participants, assigned into 2 equal groups; the sporting (N = 35) and non sporting (N = 35) group. Hemodynamic changes measured as oxyhemoglobin (oxy-Hb) and deoxyhemoglobin (deoxy-Hb) concentrations, were recorded using a portable fNIRS system.
The results revealed significant differences in CTSIB scores between the sporting and non-sporting groups in five out of the six balance conditions. The sporting group showed superior balance performance compared to the non-sporting group. The fNIRS data showed activation patterns in various regions of interest (ROIs), including the occipito-parietal, prefrontal, and temporo-parietal regions. Differences in activation between the two groups were observed in the occipito-parietal and prefrontal cortex regions, indicating distinct neural responses during the balance task.
These findings suggest that regular participation in sports activities may contribute to improved balance control and associated changes in cerebral cortex activation. The activation patterns observed in different cortical areas provide valuable insights into the neural mechanisms underlying static balance and the potential effects of sporting activities on balance control. The research findings offer insights for targeted interventions aimed at improving balance in both athletes and non-athletes. These interventions have the potential to reduce the risk of falls and enhance overall physical performance, benefiting a diverse range of individuals.
本研究旨在使用功能近红外光谱(fNIRS)研究运动和非运动组在静态平衡任务中大脑皮层激活的差异。临床感觉平衡测试(CTSIB)用于评估两组的平衡表现。
该研究涉及 70 名参与者,分为两组,每组 35 名;运动组(N=35)和非运动组(N=35)。使用便携式 fNIRS 系统记录作为氧合血红蛋白(oxy-Hb)和脱氧血红蛋白(deoxy-Hb)浓度的血流动力学变化。
结果显示,在六种平衡状态中的五种状态下,运动组和非运动组的 CTSIB 评分存在显著差异。运动组的平衡表现优于非运动组。fNIRS 数据显示在各种感兴趣区域(ROI)中存在激活模式,包括枕顶、前额和颞顶区域。在枕顶和前额皮层区域观察到两组之间的激活差异,表明在平衡任务中存在不同的神经反应。
这些发现表明,定期参加体育活动可能有助于改善平衡控制和大脑皮层激活的相关变化。不同皮层区域的激活模式为静态平衡的神经机制和体育活动对平衡控制的潜在影响提供了有价值的见解。研究结果为旨在改善运动员和非运动员平衡的针对性干预提供了参考。这些干预措施有可能降低跌倒风险,提高整体身体表现,使各种人群受益。
