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).

Sprint performance is related to muscle fascicle length in male 100-m sprinters
Journal of Applied Physiology, 2000The purpose of this study was to investigate the relationship between muscle fascicle length and sprint running performance in 37 male 100-m sprinters. The sample was divided into two performance groups by the personal-best 100-m time: 10.00–10.90 s (S10; n = 22) and 11.00–11.70 s (S11; n = 15).

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 ...
