Clinical diagnoses depend on a variety of physiological variables but the full range of these variables is seldom known. With the load placed on the human body during competitive rowing, the physiological range for several variables is illustrated. The extreme work produced during rowing is explained by the seated position and the associated ability to increase venous return and, thus, cardiac output. This review highlights experimental work on Olympic rowing that presents a unique challenge to the human capacities, including cerebral metabolism, to unprecedented limits, and provides a unique opportunity to reveal the extreme range of many physiological variables.
临床诊断取决于多种生理变量，但这些变量的完整范围很少为人所知。通过竞技划船运动中施加在人体上的负荷，可以说明几个变量的生理范围。划船时产生的高强度运动是由坐姿以及随之而来的增加静脉回流从而增加心输出量的能力所解释的。这篇综述重点介绍了关于奥运划船运动的实验工作，该运动对包括大脑代谢在内的人体能力提出了前所未有的挑战，并提供了一个独特的机会来揭示许多生理变量的极端范围。
