چکیده
The difference between the performances of Sports Champions more than other times relates to their mental fitness and one of the important factors affecting mental fitness, physical fitness and even performance is physical pressure. Given that tDCS provides potential tools for enhancing performance in many areas, there is limited exploration for complex skills. The purpose of the current study was to examine the effect of direct transcranial electrical stimulation (tDCS) in the DLPFC area on visual attention of sitting volleyball players under physical pressure. In this blind randomized control trial with pre-test-post-test research plan and follow-up period of ۲, ۴ and ۶ days, ۲۴ athletes of the Premier League and national sitting volleyball team of the country were selected as a voluntary participation, and they randomly located in ۲ groups of TDCS in the DLPFC region and sham stimulation. The task of the current study was the test of the modified Volleyball Service, in which the participants performed ۱۰ attempts in the pre-test, which visual attention were recorded using the eye tracking device. The intervention phase was performed on ۶ consecutive days, in which the participants performed ۱۰ volleyball services every day after the desired exercises. Post-test phase was performed immediately after the intervention. ۴۸ hours after the post-test phase, the first retention phase, ۴۸ hours after the first retention phase, the pressure test phase and ۴۸ hours after the pressure test phase, the second retention phase which was performed in which the participants performed ۱۰ attempts in the pre-test, which visual attention were recorded using the eye tracking device. The results of repeated measures analysis of variance test showed that tDCS exercises in DLPFC area have a significant effect on increasing participants visual attention under normal conditions and pressure testing(P< ۰/۰۱). Conclusions: In general, the results of the present study emphasize the effectiveness of tDCS in the DLPFC area on performance and visual attention under normal and physical pressure conditions.کلیدواژه ها
