It was found that in 8-9-year-old children, the hormonal part of the sympathoadrenal system more rapidly develops in boys, while the transmitter part develops more rapidly in girls. The androgenic and glucocorticoid function of the adrenal cortex matures earlier in girls. To the end of the school year, excretion of epinephrine and norepinephrine decreased, which attests to the development of fatigue.
研究发现，在8至9岁的儿童中，交感肾上腺系统的激素部分在男孩中发育得更快，而递质部分在女孩中发育得更快。肾上腺皮质的雄激素和糖皮质激素功能在女孩中成熟得更早。到学年末，肾上腺素和去甲肾上腺素的排泄量减少，这证明了疲劳的产生。
