Measurement Tools Used in the Study of Eccentric Contraction-Induced Injury
TLDR
In studies in humans and animal studies, it was concluded that measurements of maximal voluntary contraction torque and range of motion provide the best methods for quantifying muscle injury. Expand

TLDR
The best treatment for delayed-onset muscular soreness appears to be muscular activity, although the sensation again returns following the exercise, and training for the specific contractile activity that causes DOMS reduces the soreness response. Expand
Eccentric exercise-induced injury to rat skeletal muscle.
TLDR
The data generally indicated that eccentric exercise causes greater injury to the muscles, and questions remain. Expand
Muscle fiber type composition of the rat hindlimb.
TLDR
Fiber-type mass data are compared with physiological and biochemical data for the muscles taken from previous studies, and it is demonstrated that these functional properties are closely related to the proportions of muscle mass composed of the various fiber types. Expand

  • 1 August 1990
TLDR
Immediately following unaccustomed exercise, particularly that with eccentric contractions, there is evidence of injury to skeletal muscle fibers: a) disruption of the normal myofilament structures in some sarcomeres and b) loss of intramuscular proteins into the plasma, indicating damage to sarcolemma. Expand
Mechanisms of Exercise-Induced Muscle Fibre Injury
TLDR
It is argued that stresses imposed on sarcolemma by sarcomere length inhomogeneities occurring during eccentric contractions cause disruption of the normal permeability barrier provided by the cell membrane and basal lamina, and that future bouts of exercise of similar type, intensity, and duration cause less injury to the muscle.

HINDLIMB MUSCLE FIBER POPULATIONS OF FIVE MAMMALS
TLDR
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. Expand
Muscular blood flow distribution patterns as a function of running speed in rats.
Muscle blood flow (BF) was measured using the radiolabeled microsphere technique within and among nine major muscles of rats before exercise and during treadmill walking or running at speeds of 15,Expand
E-C coupling failure in mouse EDL muscle after in vivo eccentric contractions.
TLDR
Comparable reductions in Po and K+-induced force, and minor reductions in the maximal SR Ca2+ release rate, suggest that the E-C coupling defect site is located at the t tubule-SR interface immediately after injury. Expand
Enzyme activity and fiber composition in skeletal muscle of untrained and trained men.
TLDR
Succinate dehydrogenase and phosphofructokinase activities and the histochemical identification of fiber types and localization of oxidative activity were determined on biopsy samples from the vastus lateralis and deltoid muscles of 74 untrained and trained men. Expand
