Effects of Transcutaneous Vagus Nerve Stimulation on Recovery

In sports where physical loads are high, athletes can usually participate in more than one training or race during the day. Such work increases the athlete's fatigue, affects their performance and can cause serious declines. Therefore, an efficient and effective recovery process after high-intensity work and training that causes a decrease in performance is also very important for the athlete's next performance. With the start of sports activity or exercise, sympathetic activation in the body increases and after a while reaches a plateau value at maximum activity. With the end of exercise, this time the suppressed parasympathetic activity begins to increase and the sympathetic system returns to a resting state over time. There are insufficient studies in the literature investigating the use of Transcutaneous Auricular Vagus Nerve Stimulation on the athletic population. Although it is clear that the application has effects on the sympathetic and parasympathetic nervous systems, more clinical research is needed on athletes. In this study, we aimed to investigate the effects of auricular vagus nerve stimulation (VNS) on vagal activity by examining the effect of transcutaneous auricular vagus nerve stimulation on recovery in amateur athletes through applications such as pulse and SpO2, blood pressure, perceived fatigue, and respiratory function tests.
