The Effect Of Transcutaneous Auricular Vagus Nerve Stimulation On Sports Performance And Physiological Parameters (VNS001)

Objective: The aim of this study is to investigate the effect of non-invasive auricular VNS (Vagus Nerve Stimulation) on sportive performance and physiological parameters in healthy individuals.

Material and Method: 46 healthy young individuals aged 19.2(±1.5) years participated in the study. The participants were randomly divided into 3 groups as Above Threshold Group (n:15; 10 females, 5 males), Under Threshold Group (n:15; 10 females, 5 males), and Control Group (no stimulation) (n:16; 11 females, 5 males) according to the sensation of electrical current on ears. The participants were evaluated 3 times; before the application, after the first and second bicycle exercises. Numerical pain scale (NPS), pulse rate, blood pressure, respiratory rate, and distance traveled during exercise for sportive performance were recorded in kilometers as the evaluation method. The stimulation was done during the first bicycle exercise with 5 minutes of duration. The Kruskal-wallis, mann-whitney u test were used for the quantitative independent data obtained. In the analysis of qualitative independent data, chi-squared test was used.
