Ultrasound-derived Biceps Femoris Long Head Fascicle Length: Extrapolation Pitfalls [PDF]
Medicine & Science in Sports & Exercise, 2019 ABSTRACT Purpose This study aimed to compare biceps femoris long head (BFlh) fascicle length (Lf) obtained with different ultrasound-based approaches: 1) single ultrasound images and linear Lf extrapolation, 2) single ultrasound images and one of two different trigonometric equations (termed equations A and B), and 3)

Muscle in Variable Gravity: “I Do Not Know Where I Am, But I Know What to Do”
Frontiers in Physiology, 2021 Purpose: Fascicle and sarcomere lengths are important predictors of muscle mechanical performance. However, their regulation during stretch-shortening cycle (SSC) activities in usual and challenging conditions is poorly understood.

Change in length of relaxed muscle fascicles and tendons with knee and ankle movement in humans [PDF]
The Journal of Physiology, 2002 Ultrasonography was used to measure changes in length of muscle fascicles in relaxed human tibialis anterior and gastrocnemius during passively imposed changes in joint angle. Changes in the length of muscle fascicles were compared to changes in the length of the whole muscle‐tendon units calculated from joint angles and anthropometric data.

Scientific Reports, 2017 Because it is difficult to measure tendon length changes directly in humans, tendon length changes during dynamic movement have been evaluated indirectly from changes in muscle fascicle length and joint angle. The purpose of this study was to examine the

Pre-activation affects the effect of stretch-shortening cycle by modulating fascicle behavior
Biology Open, 2019 The torque attained during active shortening is enhanced after an active stretch (stretch-shortening cycle, SSC). This study examined the influence of pre-activation on fascicle behavior and the SSC effect.
