Running and flying require a substantial increase in energy expenditures and therefore a substantial elevation of respiration. Mammals and birds may have evolved mechanisms to achieve these large increases in breathing with exercise that minimizes the added cost of the breathing itself. The body of a bird is full of air sacs that are used as bellows to move air in and out of their lungs. The muscles and bones that are active and moving during flight may simultaneously assist the movement of air through its respiratory system by expanding and compressing the air sacs. This project will investigate the ways in which the muscular activities of flying and breathing are coordinated. It will provide insights into fundamental questions about the control of breathing in vertebrates, especially during exercise. Comparative studies of different species of birds and of different classes of vertebrates will also address questions about the evolution of the control of breathing during exercise. Such studies are also of value to those interested in human performance and rehabilitation.

跑步和飞行需要大量增加能量 因此，呼吸量大幅上升。 哺乳动物和鸟类可能已经进化出了实现这些功能的机制 通过运动大量增加呼吸， 呼吸本身的代价。鸟的身体充满了空气 气囊是用来作为风箱移动空气进出他们的 肺活动和运动的肌肉和骨骼在 飞行可以同时帮助空气通过其 呼吸系统通过扩张和压缩气囊。这 该项目将调查肌肉活动的方式， 飞行和呼吸是协调的。它将提供见解 关于控制吸入的基本问题 脊椎动物，尤其是在运动时。的比较研究 不同种类的鸟类和不同种类的脊椎动物 还将讨论有关控制的演变问题， 锻炼时呼吸。这些研究对那些 对人类的表现和康复感兴趣
