The Effect of Vagus Nerve Stimulation on Cycling Ergometry and Recovery

Summary

It is aIt is aimed to examine the possible benefits and effects of the use of Transcutaneous Auricular Vagus Nerve Stimulation to be applied in healthy individuals for sportive purposes on recovery and sportive performance level.

Conditions

• Healthy
• Sports Physical Therapy
• Activity, Motor

Interventions

DEVICE

Unilateral Stimulation

With the Vagustim device, vagus nerve stimulation will be applied in one ear for 20 minutes, with a frequency of 10 Hz, a pulse width of 300 μs in Modulation mode, and a constant current that the participant will feel the current comfortably.

DEVICE

Bilateral Stimulation

With the Vagustim device, vagus nerve stimulation will be applied in one ear for 20 minutes, with a frequency of 10 Hz, a pulse width of 300 μs in Modulation mode, and a constant current that the participant will feel the current comfortably.

DEVICE

Bilateral Sham Stimulation

Participants were shown that the device was working, but no current was given.

DIAGNOSTIC_TEST

Bicycle Ergometer Test

Participants in this group were asked to perform bicycle exercise with maximum performance under 30 watts for 30 minutes.

DIAGNOSTIC_TEST

Lactat Scout

For lactic acid analysis measurement, the middle fingertip of the athlete is disinfected with an alcohol swab and a blood sample is taken by puncturing the finger.The measuring range is 0.5 - 0.25 mmol/L.

DIAGNOSTIC_TEST

Polar H10

RR times transferred to computer with Polar H10 are used in heart rate variability analysis. Heart rate data will be transferred to the Kubios program and heart rate variability parameters will be calculated and data on the autonomic nervous system (RMSSD, PNS index, Stress index, SNS index, pNN50, Power LF, Power HF and LF/HF ratio) will be obtained.

DEVICE

Vagustim Device

Vagustim Health Technologies Vagus stimulator device is used for this experiment.
