Cold-induced heat production preceding shivering.
Individual changes in heat production and body temperature were studied in response to cold exposure, prior to shivering. The subjects ten women (seven men) were of normal weight, had a mean age of 23 (SD 3) years and average BMI 22.2 (SD 1.6) Kg/m2. They were lying supine under thermoneutral conditions for 30 min and were subsequently exposed to air of 15 degrees C until shivering occurred. He...
متن کاملRegulation of shivering and non-shivering heat production during acclimation of rats.
DAVIS, T. R. A., D. R. JOHNSTON, F. C. BELL AND B. J. CREMER. Regulation of shivering and nonshiuering heat production during acclimation of rats. Am. J. Physiol. 198(s) : 471-475. 1g6o.-When cold acclimating rats are treated with diathermy, curare and a combination of both, two main fractions of the increase in cold-induced oxygen consumption can be delineated. First, a fraction which diatherm...
متن کاملThe relationship of muscle electrical activity, tremor and heat production to shivering thermogenesis in Japanese quail.
We measured the electrical activity and the tremor of the pectoral muscle and total body heat production in control and cold-acclimated Japanese quail at +26 degrees C, +12 degrees C and +2 degrees C before and after 3 weeks of acclimation, using electromyography, accelerometer recordings, and indirect calorimetry. Japanese quail shiver in 0.2- to 3-s bursts that occur in groups. An increase in...
متن کاملSome Characteristics of Heat Production Using the “cold Fusion” Effect
Additional evidence is presented to show that heat production resulting from the Pons-Fleischmann Effect has a positive temperature coefficient, has a critical onset current density, and originates at the palladium cathode. Introduction The Pons-Fleischmann effect is proposed to produce energy by initiating a fusion reaction between two deuterium atoms within an electrolytic cell. While an unde...
متن کاملHeat production during anesthetic-induced malignant hyperthermia.
Malignant hyperthermia (MH) is a pharmacogenetic disease which predisposes to the trigger of a life-threatening, hypermetabolic syndrome by potent inhaled anesthetics and by depolarizing skeletal muscle relaxants. Heat production in the anesthetized MH can be profound with 5-fold increases in oxygen consumption. The trigger anesthetics cause an abnormal, sustained rise in myoplasmic calcium lev...
