Methods Twenty-four New Zealand white rabbits were surgically instrumented and underwent a bout of damaging eccentric exercise to the tibialis anterior muscle. Rabbits were randomly assigned to a protocol with massage frequency of 0.25 or 0.50Hz at a compressive force of 5 or 10N for 15 or 30 minutes. The contralateral limb served as the exercised, non-massaged control. A torque-angle relations...

A quasi-linear viscoelasticity (QLV) model was used to study passive time-dependent responses of skeletal muscle to repeated massage-like compressive loading (MLL) following damaging eccentric exercise. Six skeletally mature rabbits were surgically instrumented with bilateral peroneal nerve cuffs for stimulation of the hindlimb tibialis anterior (TA) muscles. Following the eccentric exercise, r...

The pathogenesis of ‘abfraction’ has been considered to be multifactorial with contributions from occlusal loading becoming increasingly prominent in recent years. The objective of this study was to find out whether the presence of an extensive occlusal amalgam restoration and eccentric parafunctional loads would cause increased cuspal movement and therefore, increase in cervical stress exceedi...

For the sole purpose of developing knee-flexor strength, power, and size, almost any weight room or training facility is equipped with a prone, face-down leg-curl weight-stack machine. Such commercially available machines all aim at targeting and isolating the knee-flexor muscle group. Depending on mechanical design, they differ somewhat with regard to external torque offered and hence muscle u...

Torque steadiness and low-frequency fatigue (LFF) were examined in the human triceps brachii after concentric or eccentric fatigue protocols. Healthy young males (n=17) performed either concentric or eccentric elbow extensor contractions until the eccentric maximal voluntary torque decreased to 75% of pre-fatigue for both (concentric and eccentric) protocols. The number of concentric contractio...

BACKGROUND Because muscle fascicle behavior affects to the force-generating capability, understanding of muscle fascicle length changes during dynamic movements is important. Preactivation may affect the muscle fascicle length changes, especially in the case of eccentric contraction. However, its influence has not been clarified. To this end, muscle fascicle behavior during eccentric contractio...

To analyze the clinical significance of eccentric aortic regurgitation (AR) complicating the right coronary cusp prolapse associated with a ventricular septal defect (VSD), the Doppler echocardiograms of 129 patients were reviewed. In 102 patients, AR was classified as mild and in 27 patients it was classified as moderate. Eccentric AR was defined as the jet distributing in an eccentric directi...

The purpose of this study was to determine whether superior concentric performance could be achieved in the bench throw with the use of additional eccentric loads. Fourteen male subjects performed bench throws in a smith machine with an eccentric-concentric load of 40-kg (40-40), and 40-kg concentric with additional eccentric loads of 20 (60-40), 30 (70-40), and 40 kg (80-40). A linear position...

Specifically, case two experiments centric eccentric loading solved. performed are used after for modelling when comprehensive set laboratory tests mechanical properties fiber-reinforced concrete also performed. compressive st...

Eccentric coloring is a new variation of coloring, where higher numbered colors can not be used as freely as lower numbered colors. In addition there is a correspondence between the eccentricity (max distance) of a vertex and the highest legal color for that vertex. In this note we investigate eccentric coloring of trees. We give the eccentric chromatic number or a bound on the eccentric chroma...
