Sajjad Mohammad Yari Department of Sports Science, Imam Ali Officer University , Tehran, Iran. 0000-0003-1844-4032 Journal Article 2024 06 11 Background and Aims: The purpose of this study was to compare the effect of a selected physical fitness with and without transcranial direct current stimulation (tDCS) on reaction time and shooting performance in officer students. The statistical population of the present study was all the students of Imam Ali University. Methods: Due to the type and purpose of the research, 36 students were randomly divided into 3 groups (physical fitness without TDCS (12), physical fitness with TDCS (12) and Sham (12)) as a sample of the research. The study included the pre-test and post-test steps. In the pre -test, the participants performed 10 pistol shootings and 20 efforts for each of the simple and selective reaction times and their performance was recorded. The training and stimulation period consisted of 10 sessions. The next step was similar to the pre -test and with a 24 -hour difference. The statistical method of variance analysis was used for recruitment. LSD follow-up test was used to compare couples. Findings: The results showed that physical fitness and transcranial direct current stimulation (TDCS) had a significant effect on simple and selective reaction time. Also, physical fitness with TDCS has a significant effect on shooting performance and accuracy. Conclusion According to the results of this study, it can be suggested that transcranial direct current stimulation (TDCS), which is a kind of brain stimulation, as a technique and complement to physical fitness exercises to enhance performance and cognitive-perceptual factors in military student programs Be used.
