Neural system regulation of athletes based on FNIRS and thermal radiation images: Rehabilitation of motor function

In the rehabilitation of sports function, the adjustment ability of nervous system directly affects the training effect and competitive state of athletes. In this study, FNIRS and thermal radiation imaging technology were combined to deeply analyze the nervous system activity and body surface temperature changes of athletes under different exercise loads. The athletes were asked to complete a series of standardized exercise tasks while monitoring changes in blood oxygen levels in their cerebral cortex using FNIRS devices and recording body surface temperature distributions using high-precision thermal imaging cameras. The correlation between nervous system activity and body surface temperature was studied by comparing FNIRS and thermal radiation image data under different exercise loads. The results showed that blood oxygen levels in specific areas of the athletes’ brains changed significantly during increased exercise load, indicating increased neural activity in these areas. The thermal radiation images showed that with the increase of exercise intensity, the athletes’ body surface temperature also increased significantly, especially in the areas with more muscle activity. Further analysis shows that there is a certain correlation between the rise of body surface temperature and the changes of brain blood oxygen level, especially in the key areas of motor function rehabilitation. As a non-invasive tool for real-time monitoring of body surface temperature changes, thermal radiation images can provide important physiological information for sports rehabilitation.
