About

Long-distance mountain running is increasingly popular among European and North America countries. Long-distance races are organized in various mountains and can reach up to 160 km (100 miles) with several thousands meters of climbing. The pathophysiological consequences of such extreme effort is still a matter a debate. From a muskelo-skeletal perspectives, the potential lower-limb join damage is a major health issue. The present study aims to use objective magnetic resonance imaging (MRI) techniques to describe the consequences of performing long-distance mountain running races on the knee cartilage.

Full description

Healthy male runners will perform T2 MRI knee cartilage examination before, immediatly after and 1 month after 3 distinct long-distance mountain races of 40, 55 and 160 km. The physiological responses during the races (speed, heart rate, glycemia) will also be recordered.
