The effect of long-term (7 weeks) swimming training on the content of beta-endorphin, met- and leu-enkephalins in various brain regions and adrenal glands has been studied in Wistar rats. It has been shown that the adaptation to exercise induced an increase in the content of opioid peptides in most of the brain regions and in adrenal glands. This increase in the level of opioid peptides seems to play an important role in the increase of the resistance to stress.
在Wistar大鼠中研究了长期（7周）游泳训练对不同脑区和肾上腺中β-内啡肽、甲硫氨酸脑啡肽和亮氨酸脑啡肽含量的影响。结果表明，运动适应导致大多数脑区和肾上腺中阿片肽含量增加。阿片肽水平的这种增加似乎在应激抵抗力的增强中起重要作用。
