简要总结
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).

结局指标
主要结局
Medial gastrocnemius fascicle length
时间窗: 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 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
Medial gastrocnemius pennation angle
时间窗: 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 was measured at the inferior third of muscle llength (in °) using B mode ultrasound imaging
Medial gastrocnemius thickness
时间窗: 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 was measured at the inferior third of muscle llength (in mm) using B mode ultrasound imaging
Achille tendon cross sectional area
时间窗: 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.
Mid-portion Achille tendon cross sectional area was measured (in mm²) using B mode ultrasound imaging
Medial gastrocnemius muscle length
时间窗: 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 was measured using an extended-field-of-view (EFOV) ultrasound imaging
次要结局
