The influence of myosin regulatory light chain phosphorylation on the contractile performance of fatigued mammalian skeletal muscle
… without a significant metabolic cost. Twitch force was potentiated to a greater extent in wildtype muscles until peak force had diminished to ~60% of baseline (37.2 ± 0.05% vs. 14.3 ± 0.02%). Despite no difference in peak force (Po) and shortening velocity (Vo), rate of force …

Central and peripheral determinants of fatigue in acute hypoxia
… exercise-induced decrease in maximal voluntary force produced by a muscle. Fatigue may arise from central and/or peripheral mechanisms. Supraspinal fatigue (a component of central fatigue) is defined as a suboptimal output from the motor cortex and measured using transcranial magnetic …

Sex differences in the neural control of muscle
… were seen in elbow flexor strength and rate of force development (RFD). Normalization by either maximum strength or neural factors couldn’t account for all sex-differences in RFD, resulting in an ambiguous interpretation. In contrast, both variables were able to be incorporated in an ANCOVA to …

The acute effects of whole-body vibration and heavy resistance exercise on countermovement jump
… has been recognised as an improvement in muscle-twitch force following conditioning contractile activity. The phosphorylation of myosin regulatory light chains has been identified as the principal mechanism underlying PAP. Contractile activity has been shown to produce both PAP and fatigue, and …

Myocardial force and intracellular Ca2+ in an animal model of hypertensive heart failure
… intracellular calcium ([Ca2+]i) and isometric force during the relatively narrow time frame in which long-standing compensated hypertrophy progresses to decompensated end-stage heart failure in an animal model of human essential hypertension. In order to carry out this aim, left ventricular …

Neuromuscular characteristics of eccentric contractions of the knee extensors and their muscle damage profiles
Muscle can generate greater force with lower muscle activation during eccentric (ECC) than isometric (ISO) and concentric (CON) contractions (actions). Unaccustomed ECC exercise induces muscle damage represented by prolonged impairment of muscle function and delayed onset muscle soreness (DOMS), …
