...Yan-Feng Sun; Zhi-Peng Ren; Yue-Feng Wu; Fu-Min Lei; Robert Dudley; Dong-Ming Li ABSTRACT Limits to flight performance at high altitude potentially reflect variable constraints deriving from the simultaneous challenges of hypobaric, hypodense and cold air. Differences in flight-related morphology...

... flight mechanical theory, wingbeat frequency and air speed should increase with decreasing air density, i.e. increasing flight altitude. Although wind tunnel experiments have shed light on many aspects of avian flight, the effect of air density remained ambiguous, because air density could not be...

...Mark A. Chappell; Elizabeth M. Dlugosz SUMMARY Hypoxia at high altitudes is often assumed to constrain exercise capacity,but there have been few high- versus low-altitude comparisons of species native to a wide range of altitudes. Such studies are ecologically realistic, as wild-caught animals...

Cardiorespiratory function during maximal exercise at different altitudes or at different oxygen fractions of inspired air provides a definitive test for the presence of a governor and its function. If skeletal muscle anaerobiosis is the protected variable then, under...
