The aim of the study was to investigate the short and long-term effects of breathing exercises on reaction time.

A total of 40 participants who volunteered to participate in the study from the students of the Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Bandırma Onyedi Eylül University will be included in the study. Participants will be randomly divided into two groups using a simple random numbers table. The study group (15 people) will be given respiratory exercises (12 sessions). The control group (15 people) will receive no intervention. In the study, after the demographic characteristics of the participants are obtained, reaction time will be evaluated with auditory and visual reaction tests and upper extremity reaction tests. All evaluations are planned to take a total of 15 minutes.

The same assessments will be performed in both groups. To measure the long-term effect, after the initial evaluations are completed, the study group will be given a total of 12 sessions of breathing exercises for 4 weeks (3 days a week). After 4 weeks, both groups will be evaluated again. To measure the short-term effect, the respiratory exercise program will be started after the 1st evaluation in the study group, and the 2nd evaluation will be made after the first session.

Canan Demir will perform breathing exercises, and the other researchers who will evaluate will not know which group the participants are in. In this way, the study will be single-blinded.
