Abstract:
Objective To explore the effect of transcranial direct current stimulation(tDCS) with differ-ent stimulation models over primary motor cortex(M1) on motor skill acquisition after sports fatigue in basketball players. Methods Twenty-nine basketball players(9 females and 20 males;age:19.79±0.77 year;training experience:3.40±2.16 year) received the concurrent dual-site anodal tDCS over M1,anodal tDCS over left M1(cathodal tDCS over right M1) and sham stimulation session in a coun-terbalanced order,with an interval between two sessions no less than one week. The tDCS lasted 10 min at the intensity of 2 mA,while the sham was only given for the first 30 s. In each session,sports fatigue was induced by the maximal incremental cycling exercise protocol,followed by tDCS. Subsequently,the motor skill acquisition was evaluated using the serial reaction time task(SRTT) and basketball shooting accuracy test. Results In the basketball shooting accuracy test,the shooting accura-cy increased significantly after concurrent dual-site anodal tDCS over M1 compared with sham stimula-tion(P=0.010). For SRTT,the mean errors(block 2,3 and 7) of each block decreased significantly af-ter concurrent dual-site anodal tDCS over M1,in comparison with the sham stimulation(P values<0.05 for all). Conclusion Concurrent dual-site anodal tDCS over M1 can effectively improve motor skill ac-quisition after sports fatigue in basketball players.
