Summary

This study aimed to assess the longitudinal changes in triceps surae muscle-tendon architecture to an ultra distance trail running. Experienced trail runners (N=55, 78% men, age: 45.2 \[13.5\] years) participated in a 156-km trail run (6000m climbing) consisting in six 26-km laps. The resting architectural properties of triceps surae muscle-tendon were measured using ultrasound imaging for Achille tendon cross-sectional area (AT CSA), medial gastrocnemius muscle pennation angle, thickness, length and fiber length. Measurements were performed the day before the race (Baseline), at 52-km (T1), at 104-km (T2), at 156-km (T3) and 12 hours after the race (H12).

Conditions

  • Achilles Tendinopathy
  • Calf Injury
  • Sport Injury
  • Lower Limb Injury

DIAGNOSTIC_TEST

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.
