Brief Summary

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

A significant medical risk associated with hypothermia during exercise in a cold environment cardiac arrhythmia due to a possible autonomic conflict. However, little is known about the changes in heart rate and cardiac function after prolonged cold water swimming.

The investigators propose to measure the changes in core temperarure during and after a cold water swim at at a water temperature below 15.5°C qualifying for English Channel swim and to test the association with changes in heart rate variability, resting electrocardiogram and left ventricle function.
