... maximal oxygen consumption metabolism Peromyscus maniculatus wheel-running Over the past three decades, exercise and environmental physiologists have painstakingly described the energetics of locomotion in a wide range of animals. In quadrupedal mammals running at near-thermoneutral...

... intermittency has evolved in lines of house mice (Mus domesticus) that have been selectively bred for high voluntary wheel-running (wheel diameter 1.12 m) activity. After 23 generations, female mice from four replicate selection lines ran 2.7 times more revolutions per day than individuals from four random-bred...

...John G. Swallow; Pawel Koteja; Patrick A. Carter; Theodore Garland, Jr ABSTRACT To test the hypothesis that body size and activity levels are negatively genetically correlated, we conducted an artificial selection experiment for increased voluntary wheel-running activity in house mice (Mus...
