The cost of muscle power production: muscle oxygen consumption per unit work increases at low temperatures in Xenopus laevis.
Metabolic energy (ATP) supply to muscle is essential to support activity and behaviour. It is expected, therefore, that there is strong selection to maximise muscle power output for a given rate of ATP use. However, the viscosity and stiffness of muscle increases with a decrease in temperature, which means that more ATP may be required to achieve a given work output. Here, we tested the hypothe...
متن کاملBody temperature and oxygen consumption of newborn rats at various ambient temperatures.
The thermogenic response and rectal temperature (Tre) of newborn rats (0 to 32 days old) on exposure to various ambient temperatures (Ta) were investigated. The O2 consumption (VO2 in ml . min-1 per 100 cm2 surface area) was measured for one rat at a time by means of a closed circuit system. The results were that (1) within the thermal neutral ranges, Tre stood at 36--37 degrees C regardless of...
متن کاملTissue temperatures and whole-animal oxygen consumption after exercise.
BROOKS,GEORGE A., KARL J. HITTELMAN,JOHN A. FAULKNER, AND ROBERT E. BEYER. Tissue temperatures and whole-animal oxygen consumption after exercise. Am. J. Physiol. 22 l(2) : 427-43 1. 197 l.-Forced treadmill running caused rat muscle and rectal temperatures to increase 8.1 and 5.1 C, respectively. After exercise, muscle temperature fell exponentially but did not reach control values in an hour. ...

متن کاملReset Noise at Low Temperatures
This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...
