不知道啥意思，在网上research了一下。
跑步者的愉悦感和内啡肽
跑步者的愉悦感（runner's high）是指当运动量超过某一阶段时 ， 体内便会分泌脑
内啡 。 长时间、连续性的、中量至重量级的运动、深呼吸也是分泌脑内啡的条件 。
长时间运动把肌肉内的糖原用尽 ， 只剩下氧气 ， 脑内啡便会分泌 。 这些运动包括
跑步 ， 游泳 ， 越野滑雪 ， 长距离划船 ， 骑单车 ， 举重 ， 有氧运动舞或球类
运动(例如篮球 ， 足球或美式足球) 。
内啡肽（endorphin）亦称安多芬或脑内啡 ， 是一种内成性（脑下垂体分泌）的类吗
啡生物化学合成物激素 。 它是由脑下垂体和脊椎动物的丘脑下部所分泌的氨基化合物
(肽) 。 它能与吗啡受体结合 ， 产生跟吗啡、鸦片剂一样有止痛和欣快感 ， 等同天
然的镇痛剂 。 利用药物可增加脑内啡的分泌效果 。 英文endorphin是endomorphin的
简化写法 ， endo有内在之含意 ， 而morphin则为吗啡的英文名称 ， 故endorphin有
大脑自我制造的类吗啡物质之意 。 它是归于药理学的范畴 ， 并不是化学公式化 。
endorphin具有吗啡样活性的神经肽的总称 。
Runner's high
A publicized effect of endorphin production is the so-called "runner's high"
, which is said to occur when strenuous exercise takes a person over a
threshold that activates endorphin production. Endorphins are released
during long, continuous workouts, when the level of intensity is between
moderate and high, and breathing is difficult. This also corresponds with
the time that muscles use up their stored glycogen. During a release of
endorphins the person may be exposed to bodily harm from strenuous bodily
functions after going past his or her body's physical limit. This means that
runners can keep running despite pain, continuously surpassing what they
once considered to be their limit.[citation needed]
In 2008, researchers in Germany reported on the mechanisms that cause the
runner's high. Using PET scans combined with recently available chemicals
that reveal endorphins in the brain, they were able to compare runners’
brains before and after a run.[11]
It is also suggested by many[who?]that endorphins are some of the many
chemicals that contribute to runner's high; other candidates include
epinephrine, serotonin, and dopamine.
Previous research on the role of endorphins in producing runner's high
questioned the mechanisms at work, their data possibly demonstrated that the
"high" comes from completing a challenge rather than as a result of
exertion.[12] Studies in the early 1980s cast doubt on the relationship
between endorphins and the runner's high for several reasons:
The first was that when an antagonist (pharmacological agent that blocks the
action for the substance under study) was infused (e.g. naloxone) or
ingested (naltrexone) the same changes in mood state occurred as when the
person exercised with no blocker.
A study in 2003 by the Georgia Institute of Technology found that runner's
high might be caused by the release of another naturally produced chemical,
anandamide.[13][14] The authors suggest that the body produces this chemical
to deal with prolonged stress and pain from strenuous exercise, similar to
the original theory involving endorphins. However, the release of anandamide
was not reported with the cognitive effects of the runner's high; this
suggests that anandamide release may not be significantly related to runner'
s high.[14] | p***r
