The extracellular K concentration ([K]) increases during physical exercise. We here studied whether moderately elevated [K] may increase force and power output during contractions at -like frequencies and whether such potentiation was associated with increased free cytosolic [Ca] ([Ca]) during contractions.

The delivery of mechanical power, a crucial component of animal motion, is constrained by the universal compromise between the force and the velocity of its constituent molecular systems. While the me...
Epigenetic alterations occur in various cells and tissues during aging, but it is not known if such alterations are also associated with aging in skeletal muscle. Here, we examined the changes of a pa...
Myonuclei gained during exercise-induced skeletal muscle hypertrophy may be long-lasting and could facilitate future muscle adaptability after deconditioning, a concept colloqiually termed "muscle mem...
Beta power suppression in the basal ganglia is stronger during movements that require high force levels and high movement effort but it has been difficult to dissociate the two. We recorded scalp EEG ...
Interoception has been shown to influence self-regulation of effort and perceived exertion during exercise. However, whether interoceptive accuracy influences submaximal and maximal exercise performan...
The aim of this study is to assess whether the 1 minute Sit to Stand (STS) test can be used as a measure of submaximal endurance during a pulmonary exacerbation of Cystic Fibrosis (CF) for...
Chitosan is a natural product that is produced commercially through the deacetylation of chitin, which is found in the exoskeleton of crustaceans. It has been suggested that chitosan has a...
Blood transfusions are required for patients undergoing a craniosynostosis repair due to the significant amount of blood loss. Irradiated or non-irradiated transfusions have many risks inv...
The objective of this study is to address the anti-inflammatory effect of tocotrienol supplementation in subjects with moderately elevated inflammation. It is hypothesized that 6 months s...
In the context of public health, reformulation of bread in terms of salt content remains an important measure to help achieve a reduction in salt intake in the population. Therefore, the a...
The rotational force about an axis that is equal to the product of a force times the distance from the axis where the force is applied.
Condition in which no acceleration, whether due to gravity or any other force, can be detected by an observer within a system. It also means the absence of weight or the absence of the force of gravity acting on a body. Microgravity, gravitational force between 0 and 10 -6 g, is included here. (From NASA Thesaurus, 1988)
Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.
The force applied by the masticatory muscles in dental occlusion.
Force exerted when using the index finger and the thumb. It is a test for determining maximum voluntary contraction force.
