Science at UM [S04-ep14]: Heart and lungs put to the test in ultra-triathlons
This week on A l’UM la science, Christophe Hedon, cardiologist at the University Hospital, and Olivier Cazorla, researcher at PhyMedExp, discuss the link between lung disorders and cardiac fatigue in ultra-triathletes. Sylvain Wagnon, researcher at Lirdef, is our last-minute guest, presenting a Wednesday knowledge session on the theme of School in and with nature. The program is broadcast every Wednesday on Divergence FM 93.9.
As we start the new year in January, we wish you all a very happy 2025. Perhaps you are one of the vast majority of French people who have put sport at the top of their list of New Year's resolutions! This is a godsend for gyms, which generally see a spectacular increase in membership in January. If, like me, you are not one of those who are motivated from the outset, don't feel guilty! Half of them will no longer be going to the gym in a month's time and only 20% will continue their efforts until October.
Some may become true athletes, to the point of wanting to take on the ultimate challenge: the marathon! And the craziest will aim for extreme competitions called ultra-triathlons or ultra-trails. The best known of these isthe Ironman: a 3.8 km swim, 180 km bike ride, followed by a short marathon, or 42 km run. This madness was created in 1978 in Hawaii, a country that also invented the Big Mac Supersize menu.
And before accusing me of blatant bad faith, motivated solely by my laziness, I suggest you take a look at the study our guests conducted on the possible consequences of these Herculean physical efforts on cardiac and pulmonary function. Previous studies had already revealed that this type of exercise could temporarily alter athletes' cardiac and pulmonary capacities, but these researchers are the first to have worked on the hypothesis of an association between pulmonary dysfunction and cardiac disorders.
Joining us in the studio are Christophe Hedon, cardiologist at Montpellier University Hospital, and Olivier Cazorla, CNRS researcher at the PhyMedExp laboratory.
Our last-minute guest will be Sylvain Wagnon, a researcher at Lirdef. He will present the next Wednesday Knowledge Conference on the theme of School in and with Nature.
At UM Science, you have the program, so let's get started!
