Impacts of Repetitive Transcranial Direct Current Stimulation on Athletic Performance of College Male Volleyball Players
摘要
Abstract
This study mainly explores the impacts of transcranial direct current stimulation on the serving speed,serving accuracy and athletic performance of college male volleyball players in simulated matches.By the experimental method,Methods:28 healthy male college volleyball players are randomly divided into an anodal stimulation group and a sham stimulation group,receiving continuous 5-session,5-day transcranial direct current stimulation or sham stimulation targeting the primary motor cortex.Serving tests and simulated match performance tests are conducted before and after stimulation.A two-way repeated-measures ANOVA(stimulation condition×time)is used to compare the differences in serving speed,serving accuracy,serving initiative,active actions,neutral actions and negative actions in matches before and after the two types of stimulations.Research results:In terms of the athletic performance on serving,the anodal stimulation group's serving speed is significantly higher than which before stimulation(P<0.05),while there is no significant difference in the serving speed before and after stimulation in the sham stimulation group.The total score of serving accuracy in the anodal stimulation group is significantly improved(P<0.05),and there is no change in the total score of serving accuracy before and after stimulation under sham stimulation.The number of 7-zone serves significantly increases after anodal stimulation(P<0.05),whereas there is no change in the number of 7-zone serves before and after stimulation under sham stimulation.In simulated matches,under anodal stimulation,the number of active serving actions significantly increases after stimulation(P<0.05),and the number of neutral serving actions significantly decreases compared to before stimulation(P<0.05),whereas there is no significant difference in the scores of active and neutral serving actions before and after stimulation under sham stimulation.For overall active actions in the match,the overall active actions significantly increase after anodal stimulation(P<0.05),and overall neutral actions significantly decrease after stimulation(P<0.05);in terms of overall negative actions in the matches,there is no interaction between stimulation condition and time,and the main effects of both stimulation condition and time are not significant.It argues that:Five consecutive days of transcranial direct current stimulation can enhance the special technical performance and simulated match performance of college male volleyball players.This technology can help college male volleyball players improve their muscle strength control and neural excitability,thereby increasing the performance of active actions and reducing the display of neutral actions in actual matches.关键词
