Study Summary

This research is being done to better understand the pulmonary consequences of completing an ultra marathon at altitude and a sea level city.

Primary Outcome

Cardiac ultrasound (Philips CX50) will be performed to determine left and right ventricular morphology and function. Ultrasound will be performed in accordance with the recommendations of the American Society of Echocardiography guidelines (ASE). Imaging of the ventricles and the diameter during relaxation (diastole) will be captured and evaluated. Normal value for right ventricle EDA indexed to body surface area ranges between 5-12.6 cm\^2/m\^2 for males and 4.5-11.5 cm\^2/m\^2 for females .

Interventions

  • PROCEDURE Pulsed Electromagnetic Field therapy (PEMF)
  • PROCEDURE Pulsed Electromagnetic Field Sham therapy
