Reduced visual and middle temporal gyrus activity correlates with years of exercise in athletes using resting‐state fMRI

Abstract

Background and PurposeDifferent types of physical training can lead to changes in brain activity and function, and these changes can vary depending on the type of training. However, it remains unclear whether there are commonalities in how different types of training affect brain activity and function. The purpose of this study is to compare the brain activity states of professional athletes with those of ordinary university students and to explore the relationship between training and differences in brain activity states.MethodsThis study primarily utilizes resting‐state MRI and the degree centrality metric to investigate spontaneous brain activity in 86 high‐level athletes with extensive training and 74 age‐ and gender‐matched nonathletes. Additionally, a correlation analysis between brain activity in relevant regions and years of training was conducted.ResultsThe analysis revealed that, compared to nonathletes, high‐level athletes exhibited reduced activity in the Calcarine (a visual area) and Middle Temporal Gyrus. Furthermore, changes in the activity of the Calcarine and Middle Temporal Gyrus were significantly correlated with the number of years of professional training.ConclusionsThe study results indicate that long‐term physical training is associated with changes in brain activity in athletes, providing insights into the neural mechanisms underlying behavioral performance in professional athletes.
