Conclusion
blood lactic acid, fatigue, pain
SAID
In our study, we saw that BS application gave positive results in reducing pain and fatigue due to cycling exercise compared to other applications. Similar results were obtained when we evaluated the data on a daily basis. We believe that VNS will be beneficial in reducing pain and fatigue, especially during and after the competition halftime.It can be said that our research is a pioneering study by evaluating the sportive effects of vagus nerve stimulation. It shows that especially bilateral application can improve physiological parameters (such as blood lactic acid level, blood pressure and pain) related to sports activity together with tonomic nervous system changes. Bilateral application can be a promising technique to improve sports activities (performance and recovery) by its noninvasiveness and without doping and apparent side effects.
