The Effect Of Professional Skill Training On Brain Network Reconfiguration Efficiency

The brain is a complex network system with subtle but important changes in the brain's functional network in different states.The resting state network functional connection of the brain is highly correlated with the task state network functional connection.A higher correlation indicates a more efficient network reconfiguration efficiency of the brain.Efficient network reconfiguration efficiency reflects the higher neural efficiency of the brain.Individuals with better behavioral performance tend to have higher network reconstruction efficiency.Elite athletes have excellent cognitive functions and executive functions.By comparing athletes with novices with no sports experience,it helps us to understand the impact of athletes on brain network reconfiguration efficiency after long-term professional skills training.This study takes basketball players as an example,using functional magnetic resonance imaging techniques to perform Multiple Object Tracking task(MOT)and basketball anticipation task,collecting brain structural T1,resting state,and task state of basketball players and ordinary college students of the fMRI data.The graph theory method is used to construct the brain resting state function network and the task state function network of the two groups,and compare the whole and local network properties to explore efficient brain networks.The results show that:(1)In terms of behavioral results,the correct rate of the athlete group in the Multiple Object Tracking task and the basketball anticipation task is significantly higher than the novice group.(2)The reconfiguration efficiency of the brain functional connection network is significantly positively correlated with the behavior data.(3)The brain functional connection network reconfiguration efficiency of the athlete group is significantly better than that of the novice group,and the athlete's brain function connection network reconstruction efficiency is positively correlated with the training years.(4)The network reconfiguration efficiency of the default mode network(DMN)is positively correlated with behavior data in both tasks.(5)The default mode network of the athlete group has better network reconfiguration efficiency than the novice group and is positively correlated with the training years.The results show that the brain network of high-level basketball players has more efficient network reconfiguration capabilities,reflecting the higher neural efficiency of athletes,which is related to long-term professional training.Through long-term professional skill training,athletes are pre-configured in the resting state of the brain,so that they can get into work more quickly in the task state,and get excellent task results through faster and more efficient reconfiguration.At the same time,long-term professional skills training has a greater impact on the default mode network,which can organize and transmit brain information more efficiently during tasks,and accomplish tasks more excellently.
