儿茶酚胺是一类由酪氨酸衍生而来的单胺类生物活性物质的总称,包括肾上腺素、去甲肾上腺素两种肾上腺髓质激素和脑中枢化学递质多巴胺等三种。肾上腺素和去甲肾上腺素是体内重要的升血糖激素。尤其是在运动这种应激状态下,机体需要迅速动员,大量产能,以供肌肉收缩,完成运动所需的能量。许多研究都表明运动时血浆儿茶酚胺浓度增加。国 Catecholamines are a group of monoamine bioactive substances derived from tyrosine, including adrenergic, norepinephrine and adrenergic neurotransmitter dopamine three kinds of central neurotransmitter. Epinephrine and norepinephrine are important in vivo glucagon hormones. Especially in sports such stress state, the body needs to be mobilized quickly, a lot of capacity for muscle contraction, the energy required to complete exercise. Many studies have shown that plasma catecholaminergic concentrations increase during exercise. country
