Predictability of skeletal muscle tension from architectural determinations in guinea pig hindlimbs.
TLDR
A specific tension value of 22.5 N X cm-2 appears to be a reasonable value for all mixed muscles studied in the guinea pig hindlimb and can be used to estimate their Po.Abstract:
The position of small metallic markers embedded within the lung parenchyma and glued to the pleural surface of four excised right caudal dog lobes were determined during stepwise deflation from an ...read more

Functional and clinical significance of skeletal muscle architecture.
Richard L. Lieber,Jan Fridén +1 more
TL;DR: The basic architectural properties of human upper and lower extremity muscles are described and the ability of muscles to change their architecture in response to immobilization, eccentric exercise, and surgical tendon transfer is reviewed.

A Model of the Lower Limb for Analysis of Human Movement
TL;DR: A new model of the lower limb based on data that quantifies the muscle architecture of 21 cadavers is described, which includes geometric representations of the bones, kinematic descriptions of the joints, and Hill-type models of 44 muscle–tendon compartments.

A mechanism for increased contractile strength of human pennate muscle in response to strength training: changes in muscle architecture.
Per Aagaard,Jesper L. Andersen,Poul Dyhre-Poulsen,Anne-Mette Leffers,Aase Wagner,S. Peter Magnusson,J Halkjaer-Kristensen,Erik B. Simonsen +7 more
TL;DR: The present data suggest that the morphology, architecture and contractile capacity of human pennate muscle are interrelated, in vivo, and this interaction seems to include the specific adaptation responses evoked by intensive resistance training.

Developing maximal neuromuscular power: part 2 - training considerations for improving maximal power production.
TL;DR: This series of reviews focuses on the most important neuromuscular function in many sport performances, the ability to generate maximal muscular power, and the factors that affect maximal power production.
Journal ArticleDOI
Are Current Measurements of Lower Extremity Muscle Architecture Accurate
TL;DR: This work disassembled 27 muscles from 21 human lower extremities to characterize muscle fiber length and physiologic cross-sectional area, which define the excursion and force-generating capacities of a muscle.

The variation in isometric tension with sarcomere length in vertebrate muscle fibres.
TL;DR: The variation of isometric tetanus tension with sarcomere length in single fibres from frog striated muscle has been re‐investigated with special precautions to ensure uniformity of sarcomeres length within the part of the fibre being studied.
Journal ArticleDOI
Dynamic properties of mammalian skeletal muscles.
TL;DR: The author examines the relationship between ATPase activity of myosin and intrinsic speed of shortening, and the effects of nerve cross-union on properties of myOSin.

Hindlimb muscle fiber populations of five mammals
TL;DR: It was found that the soleus and vastus intermedius muscles had the highest proportion of slow oxidative fibers in all five species, demonstrating the constancy of muscle fiber profiles dependent upon anatomical position and functional utilization.

The effects of length and stimulus rate on tension in the isometric cat soleus muscle
P. M. H. Rack,D. R. Westbury +1 more
TL;DR: By subdividing ventral roots and supplying stimulating pulses to different groups of motor units in rotation, smooth contractions of soleus could be obtained with low rates of stimulation.
Journal ArticleDOI
Muscle Architecture of the Human Lower Limb
TL;DR: The architectural features of the major knee extensors and flexors and ankle plantarflexors and dorsiflexors were determined in three human cadavers and grouped according to whether they showed a predilection for tension or velocity of shortening.
