Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Heart rate

    Heart rate variability was controlled for autonomic measurement evaluation in both groups. Polar H7 heart rate sensor chest strap and wrist watch were used to measure analytical heart rate variability.

    1 day

Study Arms (2)

Vagus nerve stimulation

EXPERIMENTAL

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.

Device: Auricular vagus nerve stimulation

Control group

SHAM COMPARATOR

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.

Device: Sham Auricular Vagus Nerve Stimulation (AVNS)
