Neuromodulation of the Autonomic Nervous System in Athletes

Summary

There are few studies in the literature that have evaluated the effects of using percutaneous stimulation of the auricular branch of the vagus nerve for sports purposes (to accelerate recovery after physical exertion). It has been demonstrated that tVNS in athletes improved the rate of heart rate recovery, reduced lactic acid levels in blood plasma, reduced pain, reduced overtraining syndrome and fatigue levels.

Eligibility

Inclusion Criteria:

* Heart rhythm and conduction disorders (frequent ventricular and supraventricular extrasystoles, first-degree atrioventricular block (P-Q \> 0.21 s, not shortened during hyperventilation or physical exertion), second or third degree);
* Expressed sinus bradycardia with resting heart rate \< 40 bpm;
