Do mice bred selectively for high locomotor activity have a greater reliance on lipids to power submaximal aerobic exercise?

Abstract excerpt

Patterns of fuel use during locomotion are determined by exercise intensity and duration, and are remarkably similar across many mammalian taxa. However, as lipids have a high yield of ATP per mole and are stored in large quantities, their use should be favored in endurance-adapted animals. To examine the capacity for alteration or differential regulation of fuel-use patterns, we studied two lines of mice that...
