Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Performance is defined as the physiological potential required for an individual's physical activity. The sportive activity that he creates with his potential is defined as the sportive performance level of the individual. There are many factors that determine athletic performance. These factors are; environmental factors such as heredity, physical structure, training level, technical capacity and mental adequacy, quality of training areas, nutritional quality, suitability in weather conditions. All these factors affect the planning of multidisciplinary and interdisciplinary approaches that affect the performance of the athlete.

Autonomic regulation is very important for the reorganization of the athlete's performance. Auricular vagus nerve stimulation (VNS) is a non-invasive method. With this method, autonomic nervous system regulation can be done practically. In the literature, there are no studies examining the effect of VNS on recovery and performance in athletes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study, the effects of auricular vagus nerve stimulation on performance and recovery were investigated, which was designed as a randomized controlled trial, a single session of VSU was applied to 60 male professional athletes (30 experimantal, 30 control). The normal application waveform was biphasic asymmetric, with a pulse duration of 300 microseconds and a frequency of 25 hertz, for 20 minutes and continuously.

Vagus nerve stimulation

Auricular Vagus Nerve Stimulation (AVNS) was applied to the experimental group. AVNS application was applied to both ears simultaneously for 20 minutes, with waveform biphasic asymmetric, pulse duration 300 microseconds and frequency 25 hertz. AVNS application was made with Vagustim brand device.

The acute effect of the application was evaluated in both groups by isometric quadriceps strength measurement, heart rate variability measurement, grip strength measurement and modified star balance test measurement performed before and after the single session AVNS.

Control group

Sham Auricular Vagus Nerve Stimulation (AVNS) was applied to the experimental group. AVNS application was applied to both ears simultaneously for 20 minutes, with no pulse. AVNS application was made with Vagustim brand device.

Before and after sham AVNS isometric quadriceps strength measurement, heart rate variability measurement, grip strength measurement and modified star balance test measurement performed.
