...Jarren C. Kay; Jocelyn Ramirez; Erick Contreras; Theodore Garland, Jr ABSTRACT Muscle pH decreases during exercise, which may impair function. Endurance training typically reduces muscle buffering capacity as a result of changes in fiber-type composition, but existing comparisons of species...

We then measured energetic expenditure both at rest and immediately following exercise to test whether such training alters the maintenance and production...

Ninety-six mice from generation 49 were familiarized with running on a motorized treadmill for 3 days. On days 4 and 5, mice were given an incremental speed test (starting at 20 m min...

The percentage of strides that each species ran bipedally, recorded using high speed video cameras, was positively related to body size and the proximity of the body centre of mass to the hip, and negatively related to running endurance. Speed was not higher for bipedal strides, compared...
