Experienced long-distance trail runners
All the participants of the First 'Trail Scientifique de Clécy 2021". This was a multidisciplinary protocol to investigate the mechanisms that contribute to performance during an ultradistance trail race (156-km)
Ultrasound measurement of triceps surae muscle-tendon architecture
The resting plantar-flexors MTU architecture assessment was performed using a conventional B-mode and extended-field-of-view (EFOV) ultrasound imaging. Achille tendon cross-sectionnal area, Medial gastrocnemius thickness, pennation angle, fascicle length and muscle length were collected on the dominant lower limb.
