AIM To investigate whether there is a sex difference in exercise induced muscle damage. MATERIALS AND METHOD Vastus Lateralis and patella tendon properties were measured in males and females using ultrasonography. During maximal voluntary eccentric knee extensions (12 reps x 6 sets), Vastus Lateralis fascicle lengthening and maximal voluntary eccentric knee extensions torque were recorded eve...

Explants of fetal rat sensory ganglia, cultured under conditions allowing axon and Schwann cell outgrowth in the absence of fibroblasts, occasionally develop nerve fascicles that are partially suspended in culture medium above the collagen substrate. In these suspended regions, fascicles are abnormal in that Schwann cells are decreased in number, are confined to occasional clusters along the fa...

This fascicle is based on data from the Québec Longitudinal Study of Child Development (QLSCD 1998-2010) which is being conducted by the Institut de la statistique du Québec (Québec Institute of Statistics) in collaboration with various partners (lis ted on the back cover). The goal of this study is to gain a better understanding of the trajectories which, during early childhood, lead to childr...

The developmental goal of 3D ultrasound imaging (3DUS) is to engineer a modality to perform 3D morphological ultrasound analysis of human muscles. 3DUS images are constructed from calibrated freehand 2D B-mode ultrasound images, which are positioned into a voxel array. Ultrasound (US) imaging allows quantification of muscle size, fascicle length, and angle of pennation. These morphological vari...

INTRODUCTION When a muscle shortens it must increase in transverse crosssectional area in order to minimize any changes in volume. This increase in cross-sectional area may occur as a bulging in depth or in width. Pennate muscles have structural asymmetries due to the nature of the pennation, and thus may have asymmetries between the bulging in depth or width. Muscle depth can be considered as ...

The Achilles tendon (AT) consists of distinct fascicle bundles arising from the gastrocnemius and soleus muscles that intertwine and twist before inserting onto the calcaneus [1]. Current musculoskeletal models simplify this architecture by representing the gastrocnemius and soleus as independent muscle-tendon actuators [2], which may be an appropriate assumption if the fascicles freely slide r...

Rehabilitative body weight supported gait training aims at restoring walking function as a key element in activities of daily living. Studies demonstrated reductions muscle and joint forces, while kinematic patterns appear to be preserved with up 30% support. However, the influence support on architecture, respect fascicle series elastic behavior is unknown, despite this having potential clinic...
