Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Nineteen recreational cyclists performing "L'ETAPE DU TOUR (EDT) de France" a cycling ride (175 km, 3600 m of positive altitude difference) on July 4 2021 will be included in this study. Each participant will complete a detailed questionnaire detailing their training history. All participants will have exercise testing approximately 1 week before the EDT stage to set aerobic and anaerobic gas exchange thresholds, as well as VO2max.
In part 2 of the study cardiac MRI will be performed at rest before the EDT cycling ride completion. An ECG registration using a RootiRx will be realized during and up to 6 hours after the cycling ride. An echocardiography and cardiac MRI will be repeated in each cyclist between 3 and 6 hours after EDT cycling ride completion. A blood sample will be obtained at that time after the ride. This time point is chosen based on the highest troponin release that 3 to 6 hours post-exercise would allow a sufficient amount of time for inflammation to develop and be detectable, corresponding with the time when cardiac Troponin T is typically detectable and representing the liberation of enzymes from damaged myocytes.
Finally, a third cardiac MRI will be repeated 24 hours after start of the cycling ride to verify the evolution of possible inflammation over this time period.

Recreational cyclists performing the 'étape du tour (EDT) de France 2021
cardiac MRI
T1 and T2 relaxation times will be evaluated on basal and mid-cavity SA maps; a single ROI measurement in the septum will be manually drawn sufficiently far from tissue interfaces to avoid the impact of susceptibility artifacts from adjacent tissues. The differences in T1 and T2 relaxation times between rest and post-exercise will be analyzed.
Cardiac ventricular volumes, function and LV mass will also be quantified.
Echocardiography
Measurements of mass, volumes and function will be obtained of both the left and right ventricles enabling comparisons with cardiac MRI and traditional echo measures.
RootiRx for the ECG monitoring during the cycling ride
The final report will include the amount of recorded beats, the average heart rate, the maximum and minimum heart rate, the amount of cardiac pauses defined as an interruption in the ventricular rate \> 2 seconds. Reported atrial events include atrial ectopic beats and supraventricular tachycardia and ventricular events include ventricular ectopic beats, doublets, triplets, bigeminy, trigeminy and ventricular tachycardia.
Blood sample
Blood sample will be performed 3 to 6 hours after the stage to analyze high-sensitivity cardiac Troponin T (high-sensitivity) levels, Creatine Phosphokinase (CPK) to eliminate the hypothesis of Troponin elevation induced by rhabdomyolysis and C-reactive Protein to corroborate the inflammatory aspect if there is any.
