... magnitude of thermal plasticity may be masked or modified under food restriction. This reduction in RMR was associated with atrophy and decreases in in vivo protein synthesis rates, primarily in non-essential tissues. Remarkably, food deprivation had no effect on maximum oxygen uptake rates and thus aerobic...

... for swimming (CTS max ) while exercising aerobically until fatigue and the critical thermal maximum (CT max ) under static conditions until loss of equilibrium (LOE). In the CTS max protocol, warming caused a profound increase in the rate of oxygen uptake ( Ṁ O 2 ), culminating in a gait transition from steady...

Although influential theory claims that metabolic scaling is constrained by internal body design, our study builds on previous work to show...

Thus, bar-headed geese reared at high altitude exhibited a reduced oxygen demand at rest and a modest but significant increase in oxygen uptake and delivery during progressive hypoxia compared with bar-headed geese reared at low altitude. Each goose...
