... prevented growing guinea fowl ( Numida meleagris ) from jumping. We compared the jump performance of our treatment group at maturity with that of controls and measured the morphology of the gastrocnemius elastic system. We found that restricted birds jumped with lower jump power and work, yet there were...

These different loading regimes were designed to separately influence the energy use...
