Fowl weather workout
The researchers placed six guinea fowl on a treadmill and gave them three different workouts. During one, they wore a weighted backpack to work the stance muscles; a second featured ankle weights to work the swing muscles. The third was a no-load workout.
So says a May 16, 2006 report in ScienceNow.
The formal study is titled “The energetic costs of trunk and distal-limb loading during walking and running in guinea fowl Numida meleagris : I. Organismal metabolism and biomechanics.”
