During exercise, circulatory reflexes ensure that the cardiac output is sufficiently elevated to meet the oxygen delivery requirements of the contracting skeletal muscles and the heat delivery requirements of the body to the skin. The latter requirements are met by increasing skin blood flow. These increases are largely driven by elevations in the body temperatures, although non-thermal effects on the control of skin blood flow occur in certain conditions. These effects are largely the consequence of high and/or low baroreflex stimulation. Even in the face of such non-thermal effects, which occur during exercise in the heat, the body's requirements for heat transfer from core to skin are largely met by the increased skin blood flow. Thus, non-thermal effects on the control of skin blood flow are relatively unimportant in the body's overall regulatory response to exercise.
在运动过程中，循环反射可确保心输出量充分增加，以满足收缩的骨骼肌对氧气输送的需求以及身体向皮肤散热的需求。后一种需求是通过增加皮肤血流量来满足的。这些增加在很大程度上是由体温升高驱动的，尽管在某些情况下对皮肤血流控制存在非热效应。这些效应主要是高和/或低压力反射刺激的结果。即使在热环境中运动时出现这种非热效应，身体从核心向皮肤传热的需求在很大程度上仍可通过增加的皮肤血流量来满足。因此，对皮肤血流控制的非热效应在身体对运动的整体调节反应中相对不重要。
