Obese super athletes: fat-fueled migration in birds and bats

CG Guglielmo - Journal of Experimental Biology, 2018‏ - journals.biologists.com
Migratory birds are physiologically specialized to accumulate massive fat stores (up to 50–
60% of body mass), and to transport and oxidize fatty acids at very high rates to sustain flight …

The role of the antioxidant system during intense endurance exercise: lessons from migrating birds

C Cooper-Mullin… - Journal of Experimental …, 2016‏ - journals.biologists.com
During migration, birds substantially increase their metabolic rate and burn fats as fuel and
yet somehow avoid succumbing to overwhelming oxidative damage. The physiological …
