Changes in plasma glucose and lipid concentrations during treadmill exercise in domestic fowl

Fuel use and metabolic response to endurance exercise: a wind tunnel study of a long-distance migrant shorebird

“…This finding is in agreement with all studies of exercising birds, e.g. domestic fowl running on a treadmill (Brackenbury and El-Sayed, 1984), flying pigeons (Bordel and Haase, 1993;Schwilch et al, 1996;Vallyathan and George, 1969;John et al, 1988;George et al, 1989) and small passerines (Jenni-Eiermann and Jenni, 1991) as well as studies on exercising mammals and humans (e.g. Paul, 1975;Keul, 1975).…”

“…We observed lower plasma triglyceride and VLDL concentrations in flying than in resting knots. This is in accord with most studies on endurance exercise of mammals and larger birds (Keul, 1975;Liesen et al, 1975;Paul, 1975;Brackenbury and El-Sayed, 1984) in which decreased plasma triglyceride levels were recorded during heavy endurance exercise. In homing pigeons, triglyceride levels and the fraction of VLDLs were lower (short flights) or only slightly higher (longer flights) in flying than in resting birds (Bordel and Haase, 1993;Schwilch et al, 1996).…”

“…In two out of three species of flying small passerine, no changes in plasma glucose levels were found in comparison with fasted individuals (Jenni-Eiermann and Jenni, 1991). In flying pigeons (Bordel and Haase, 1993;Schwilch et al, 1996) and in exercising domestic fowl (Brackenbury and El-Sayed, 1984), unchanged or slightly lower glucose levels were found compared with resting birds.…”

Secretory Pattern of Growth Hormone, Insulin, and Related Metabolites in Growing Male Turkeys: Effects of Overnight Fasting and Refeeding

“…The current study (Experiment 2) indicated little evidence of a direct relation between GH and fat mobilization in vivo as indicated by previous studies (Brackenbury and El-Sayed, 1984;Brackenbury et al, 1987) that described the GH-released increases in the circulating levels of plasma nonesterified fatty acids. The mechanisms involved in lipolysis may be quite complex, as indicated by the dynamic nature of NEFA.…”
