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).

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | 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. | |
Primary | 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. | |
Primary | 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. | |
Primary | 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. | |
Primary | Medial gastrocnemius muscle length | Medial gastrocnemius muscle length was measured using an extended-field-of-view (EFOV) 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. | |
Secondary | 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 | |
Secondary | Average speed | Average speed was calculated using the time per lap and distance for each lap | Four time point (1) during the race, at 52-km, (2) during the race, at 104-km, (3) during the race, at 156-km and (4) for the whole race. |
