Postcontraction changes of muscle architecture in human quadriceps muscle

Muscle & Nerve, 2004
AbstractMaximal voluntary contraction changes the mechanical properties of skeletal muscle. Using ultrasound, we investigated whether these changes are reflected by changes in muscle architecture in the vastus lateralis muscle of 8 healthy volunteers. The mean pennation angle during the time interval from 3 to 6 min after maximal voluntary contraction (

Effect of resistance training to muscle failure vs non-failure on strength, hypertrophy and muscle architecture in trained individuals

Biology of Sport, 2020
The aim of this study was to compare the effects of resistance training to muscle failure (RT-F) and non-failure (RT-NF) on muscle mass, strength and activation of trained individuals.

Muscle-fibre architecture of the rat medial pterygoid muscle

Archives of Oral Biology, 1987
The detailed fibre architecture of the rat medial pterygoid muscle, including the courses and attachment points of muscle fibres, was investigated histologically in 10 micron thick serial sections in the horizontal, coronal and parasagittal planes.

Rate of Force Development, Muscle Architecture, and Performance in Elite Weightlifters.

International Journal of Sports Physiology and Performance, 2020
PURPOSE The purpose of the present study was to investigate the relationship between weightlifting performance and the rate of force development (RFD), muscle architecture, and body composition in elite Olympic weightlifters.

Shoulder and Upper Arm Muscle Architecture

The Journal of Hand Surgery, 2011
To examine the architecture of the shoulder and upper arm muscles and generate data that could serve as a guide for comparison, compatibility, and relative performance among these muscles for use in transfer.Eleven shoulder and arm muscles were dissected bilaterally in 5 fresh cadavers.

Fiber architecture of canine abdominal muscles

Journal of Applied Physiology, 2002
During respiration, abdominal muscles experience loads, not only in the muscle-fiber direction but also transverse to the fibers. We wondered whether the abdominal muscles exhibit a fiber architecture that is similar to the diaphragm muscle, and, therefore, we chose two adjacent muscles: the internal oblique (IO), with about the same muscle length as ...

Rotator Cuff Muscle Architecture

Clinical Orthopaedics and Related Research, 2006
We examined the architectural properties of the rotator cuff muscles in 10 cadaveric specimens to understand their functional design. Based on our data and previously published joint angle-muscle excursion data, sarcomere length operating ranges were modeled through all permutations in 75 masculine medial and lateral rotation and 75 masculine abduction

Clinical Significance of Skeletal Muscle Architecture

Clinical Orthopaedics and Related Research, 2001
Skeletal muscle architecture is one of the most important properties that determines a muscle's force and excursion capability. In the current review, basic architectural terms first are reviewed and then specific examples relevant to upper extremity anatomy are presented.

Architectural differences between the hamstring muscles

Journal of Electromyography and Kinesiology, 2012
The purpose of this study was to understand the detailed architectural properties of the human hamstring muscles. The long (BFlh) and short (BFsh) head of biceps femoris, semimembranosus (SM) and semitendinosus (ST) muscles were dissected and removed from their origins in eight cadaveric specimens (age 67.8±4.3 years).

Architecture of the Human Pterygoid Muscles

Journal of Dental Research, 1995
Muscle force is proportional to the physiological cross-sectional area (PCSA), and muscle velocity and excursion are proportional to the fiber length. The length of the sarcomeres is a major determinant of both force and velocity. The goal of this study was to characterize the architecture of the human pterygoid muscles and to evaluate possible ...
