The effect of a selected physical fitness with and without transcranial direct current stimulation (tDCS) on reaction time and shooting performance in officer students
With the aim of comparing the effect of a period of selected physical training exercises with and without transcranial direct electrical stimulation of the brain (tDCS) on reaction time and shooting performance in officer students.
Design
36 students are randomly divided into 3 groups of physical fitness without tDCS, physical fitness with tDCS and placebo group. Sampling is done randomly. The total sample size will be 36 people. The clinical trial will have a control group with parallel groups.
Settings and conduct
The research will be done in Afsari University. The number of stimulation and training sessions will be 10 sessions in total.
Participants/Inclusion and exclusion criteria
Among the criteria for entering the research, students were familiar with shooting techniques, no smoking, no history of cardiovascular disease, blood, liver, respiratory diseases, and no use of energizing supplements and androgenic drugs. The criterion for not entering the study was that the subject was not able to perform the physical fitness test or perform other psychological exercises at the same time as the psychological interventions of the current study.
Intervention groups
36 students are randomly divided into 3 groups of physical fitness without tDCS, physical fitness with tDCS and placebo group. The physical fitness group without tDCS does physical fitness exercises in 10 sessions and each session lasts 60 minutes.
In the physical fitness group with tDCS, participants will receive and perform 10 sessions of tDCS along with physical fitness exercises.
The placebo group will also receive 10 sessions of sham tDCS stimulation.

Randomization (investigator's opinion)
Randomized
Randomization description
In this study, the purposeful sampling method is used. The random number table method will be used to assign people to two experimental and control groups. In this method, a list of people (third and fourth year entering the university) who want to be selected as a sample is prepared. Determining a random list To perform a simple random sampling, the Random Number Generator tool in Google is used. The randomization unit is also individual. The control/experimental group ratio will be 1:1.
