Biceps femoris fascicle length during passive stretching
Journal of Electromyography and Kinesiology, 2018The purpose of this study was to quantify the relative changes in fascicle (FL) and muscle-tendon unit (LMTU) length of the long head of the biceps femoris (BFlh) at different combinations of hip and knee joint positions. Fourteen participants performed passive knee extension trials from 0°, 45° and 90° of hip flexion.

Vastus Lateralis Fascicle Length Changes During Stair Ascent and Descent
Journal of Orthopaedic & Sports Physical Therapy, 2008Experimental descriptive laboratory study.To describe the change in fascicle length of the human vastus lateralis (VL) muscle during the stance phase of stair ascent and descent.Muscle fascicle length changes during lower limb functional activities, such as walking and jumping, do not always coincide with joint angle changes.Thirty-three healthy ...

Muscle enlargement in sumo wrestlers includes increased muscle fascicle length
European Journal of Applied Physiology, 2000Skeletal muscle architecture was measured in 28 college sumo wrestlers (Sumo) and 30 control subjects. Pennation angle (PAN) and muscle thickness (MTH) of the triceps long head (TL), vastus lateralis (VL) and gastrocnemius medialis (MG) and lateralis (LG) muscles were measured by B-mode ultrasonography, and fascicle length (FAL) was estimated.

Fascicle Length Change of the Human Tibialis Anterior and Vastus Lateralis During Walking
Journal of Orthopaedic & Sports Physical Therapy, 2007A single-group descriptive experimental design.To determine the fascicle length change in the tibialis anterior (TA) and the vastus lateralis (VL) muscles during walking.The length of the muscle fibers during isometric actions and during dynamic functional activities is affected by the compliance of the tendon and aponeurosis.

In vivo Measurement of Fascicle Length and Pennation Angle of the Human Biceps femoris Muscle
Cells Tissues Organs, 2001The purpose of this investigation was to measure in vivo fascicle length (L<sub>fas</sub>) and pennation angle (PA) of the long head of the biceps femoris muscle (BF<sub>lh</sub> m.) at different hip and knee angles while the muscle was relaxed using ultrasonography (US).

Forefoot running requires shorter gastrocnemius fascicle length than rearfoot running
Journal of Sports Sciences, 2019This study aimed to investigate the influence of foot strike patterns on the behaviour of the triceps surae muscle-tendon unit, including the Achilles tendon whose length nearly corresponds to force of the triceps surae, and the medial gastrocnemius muscle (MG) during running.

Effects of dynamic resistance training on fascicle lengthand isometric strength
Journal of Sports Sciences, 2006The aims of this study were to assess changes in muscle architecture, isometric and dynamic strength of the leg extensor muscles, resulting from dynamic resistance training, and the relationships between strength and muscle architecture variables. The participants (n = 30) were randomly assigned to one of two groups.

In vivo operational fascicle lengths of vastus lateralis during sub-maximal and maximal cycling
Journal of Biomechanics, 2010Instantaneous contractile characteristics of skeletal muscle, during movement tasks, can be determined and related to steady state mechanical properties such as the force-length relationship with the use of ultrasound imaging. A previous investigation into the contractile characteristics of the vastus lateralis (VL) during cycling has shown that ...
