The purpose of this systematic review was to determine the effects eccentric training on muscle architecture in adult population. Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with muscular training. Four databases used: PubMed, Scopus, SPORTDiscus Web Science. Methodological quality assessed PEDro scale. A total 12...

INTRODUCTION Despite structural distinction between the transverse and oblique heads of the adductor pollicis, in vivo testing continues to consider the adductor pollicis as functionally simplistic. As a muscle's architecture is a strong indicator of function, in this study we aimed to determine whether the physiological cross-sectional areas (PCSAs) of both heads were uniform. METHODS Classi...

The present study examined the morphometric properties of the forelimb, including the inertial properties of the body segments and the morphometric parameters of 21 muscles spanning the shoulder and/or elbow joints of six Macaca mulatta and three M. fascicularis. Five muscle parameters are presented: optimal fascicle length (L(0)(M)), tendon slack length (L(S)(T)), physiological cross-sectional...

Introduction: After rotator cuff tendon tear, the corresponding musculotendinous unit may retract massively, accompanied by severe fatty infiltration of the muscle tissue. The retraction of the tendon and muscle is the main reason for the irreparability of long-standing rotator cuff tendon tears. The amount of retraction of the musculotendinous unit is usually estimated by the size of the gap b...

Proton density (PD) and diffusion tensor imaging (DTI) are techniques that enable the acquisition of data from living subjects can be used in fine-tuning subject-specific models’ architectural parameters. The aim this study was to determine vivo 3D parameters (volume, pennation angle, fiber length physiological cross-sectional area) gastrocnemius medialis, lateralis, soleus tibialis anterior mu...

Scratch-digging mammals are commonly described as having large, powerful forelimb muscles for applying high force to excavate earth, yet studies quantifying the architectural properties of the musculature are largely unavailable. To further test hypotheses about traits that represent specializations for scratch-digging, we quantified muscle architectural properties and myosin expression in the ...
