Male, Wistar rats were sprint trained using a high intensity, interval type, treadmill running protocol. Sprint training produced a significant decrease in plasma beta-endorphin levels. Conversely, animals who performed a high intensity acute run displayed significant increases in the concentration of plasma beta-endorphin which may be stress-related. Neither training nor acute running had any significant effect on the beta-endorphin levels of the pituitary, cortex, posterior or anterior hypothalamus.
雄性Wistar大鼠采用高强度间歇式跑步机跑步方案进行冲刺训练。冲刺训练使血浆β-内啡肽水平显著降低。相反，进行高强度急性跑步的动物血浆β-内啡肽浓度显著升高，这可能与应激有关。训练和急性跑步对垂体、皮质、下丘脑后部或前部的β-内啡肽水平均无显著影响。
