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 ...

The fascicle length obtained by ultrasound imaging is one of the crucial muscle architecture parameters for understanding the contraction mechanics and pathological conditions of muscles. However, the lack of a reliable automatic measurement method restricts the application of the fascicle length for the analysis of the muscle function, as frame-by ...

Computer Methods in Biomechanics and Biomedical Engineering, 2013 Manual tracking of muscle fascicle length changes from ultrasound images is a subjective and time-consuming process. The purpose of this study was to assess the repeatability and accuracy of an automated algorithm for tracking fascicle length changes in ...

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.

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).

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.

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.
