10名健康正常体重的年轻男性在四种测试情况下进行了研究，旨在阐明体温升高与运动本身对垂体激素释放的相对作用。在测试期间连续记录鼓膜温度。由外部加热引起的静息体温升高导致血清催乳素（PRL）的平行变化，也发现温度自发恢复正常时。相反，通过运动（450 kpm/min，40 min）相同幅度的温度升高不会引起Prl分泌的变化。结果表明，核心温度的升高是一种催乳素分泌的刺激，运动明显抑制这种刺激作用。
Ten young healthy normal-weight males were studied in four test situations designed to elucidate the relative role of body temperature increase vs that of exercise per se for pituitary hormone release. Tympanic temperature was recorded continuously during the tests. Elevation of body temperature at rest induced by external heating resulted in parallel changes in serum prolactin (Prl), also found when temperature spontaneously returned towards normal. In contrast, temperature elevation of the same magnitude through exercise (450 kpm/min for 40 min) induced no change in Prl secretion. It is concluded that increase in core temperature is a stimulus of Prl secretion and suggested that exercise apparently inhibits the stimulatory effect.
