The importance of β-adrenergic signaling in the heart has been well documented, but it is
only more recently that we have begun to understand the importance of this signaling …

Impaired calcium release from the sarcoplasmic reticulum (SR) has been identified as a
contributor to fatigue in isolated skeletal muscle fibers. The functional importance of this …

Thermogenesis by resting muscle varies with conditions and plays an active role in
homeostasis of body weight. The low metabolic rate of living resting muscles requires that …

Our aim is to describe the acute effects of catecholamines/β‐adrenergic agonists on
contraction of non‐fatigued skeletal muscle in animals and humans, and explain the …

Skeletal muscle excitation–contraction (EC) coupling is initiated by sarcolemmal
depolarization, which is translated into a conformational change of the dihydropyridine …

Resting skeletal muscle is a major contributor to adaptive thermogenesis, ie, the
thermogenesis that changes in response to exposure to cold or to overfeeding. The …

Important differences exist between perfused and incubated (or perifused) skeletal muscle
preparations with regard to their metabolism and control. A growing body of evidence …

Although force fluctuations during a steady contraction are often heightened in old adults
compared with young adults and are enhanced in young adults during the stress response …

A long-duration, submaximal contraction of a hand muscle increases central fatigue during a
subsequent contraction in the other hand. However, this' cross-over'of central fatigue …

Background β 2-adrenergic receptors (β 2 ARs) are the target of catecholamines and play
fundamental roles in cardiovascular, pulmonary, and skeletal muscle physiology. An …
