Arms/Interventions Module

Arm Groups

Label	Type	Description	Intervention Names
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)	Diagnostic Test: Ultrasound measurement of triceps surae muscle-tendon architecture

Interventions

Name	Type	Description	Arm Group Labels	Other Names
Ultrasound measurement of triceps surae muscle-tendon architecture	Diagnostic Test	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.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Achille tendon cross sectional area	Mid-portion Achille tendon cross sectional area was measured (in mm²) using B mode ultrasound imaging	Five time points: (1) at baseline, the day before the 156-km race, (2) during the race, at 52-km, (3) during the race, at 104-km, (4) immediately after the race, at 156-km and (5) at 12-hours after arrival.
Medial gastrocnemius thickness	Medial gastrocnemius thickness was measured at the inferior third of muscle llength (in mm) using B mode ultrasound imaging	Five time points: (1) at baseline, the day before the 156-km race, (2) during the race, at 52-km, (3) during the race, at 104-km, (4) immediately after the race, at 156-km and (5) at 12-hours after arrival.
Medial gastrocnemius pennation angle	Medial gastrocnemius pennation angle was measured at the inferior third of muscle llength (in °) using B mode ultrasound imaging	Five time points: (1) at baseline, the day before the 156-km race, (2) during the race, at 52-km, (3) during the race, at 104-km, (4) immediately after the race, at 156-km and (5) at 12-hours after arrival.
Medial gastrocnemius fascicle length	Medial gastrocnemius fascicle length was calculated under the assumption of linearity as Fascicle Lnegth = Muscle Thickness / sin (Pennation angle) measured at the inferior third of muscle length (calculated in mm) using B mode ultrasound imaging	Five time points: (1) at baseline, the day before the 156-km race, (2) during the race, at 52-km, (3) during the race, at 104-km, (4) immediately after the race, at 156-km and (5) at 12-hours after arrival.
Medial gastrocnemius muscle length	Medial gastrocnemius muscle length was measured using an extended-field-of-view (EFOV) ultrasound imaging

Secondary Outcomes

Measure	Description	Time Frame
Finisher status	Participants were classifioed as "Finishers" or "Did not finish" whether they completed the 156-km race, or not	One time point, after the race
Average speed	Average speed was calculated using the time per lap and distance for each lap
