由于原文实在太长,因此就不贴原文了。
你提到的第一篇论文:Is advice for breakfast consumption justified? Results from
a short-term dietary
and metabolic experiment in young healthy men. (Martin et al.,2000)
文章实际上要说的是,
早餐摄取高热量与低热量饮食的比较,结果发现低热量饮食比较好,
而论文的设计没有用低热量饮食vs完全不吃。
A high glycaemic response was observed in the morning after the high-energy br
eakfast period, while there was a peak of free fatty acids after the low-energ
y breakfast. The high-energy breakfast induced a strong inhibition of fat oxid
ation throughout the day. Although long-term adaptation to a high-energy break
fast cannot be excluded, the high-energy breakfast in this study did not appea
r to be favourable to health. Our results do not support the current advice to
consume more energy at breakfast.
第二篇提到的论文: Breakfast, blood glucose, and cognition.(Benton D, & Parker
PY,1998)
Abstract提到:早餐禁食会让记忆力和认知能力下降,而喝含葡萄糖补充品可逆转此现象
morning fasting was found to adversely affect the ability to recall a word lis
t and a story read aloud, as well as recall items while counting backwards,
the decline in performance associated with not eating breakfast was reversed b
y the consumption of a glucose-supplemented drink
第三篇提到的论文:Breakfast reduces declines in attention and memory over the
morning in
schoolchildren.(Wesnes KA et al., 2003)
这篇更让我笑出来,论文标题本来就已经在谈:帮助减缓注意力和记忆力下降的早餐
所以不用看内文就已经知道这article不是在论述不吃早餐能提升认知能力
不过我还是看了内文,文中提到:
只喝葡萄糖饮料而完全不吃早餐,会让注意力和记忆力下降,
不过吃麦片则能维持这方面的认知能力。
The glucose drink and No breakfast conditions were followed by declines in att
ention and memory, but the declines were significantly reduced in the two cere
al conditions. This study provides objective evidence that a typical breakfast
of cereal rich in complex carbohydrates can help maintain mental performance
over the morning.
第四篇提到的论文:The effect of a lowcarbohydrate diet on performance, hormona
l and metabolic responses to a 30-s bout of supramaximal exercise.
本论文提到:
1.低碳饮食对于无氧运动的表现有害,因为会减少肌肉内的肝糖储存以及降低葡萄糖分解
作用
2.在运动后三天内休息时减少碳水化合物摄取会增加交感神经作用(个人解读,本文没提
到增加交感神经作用对运动表现会怎么样,无法以此来解读增加交感神经作用就能提升运
动表现,其实个人认为,过高的交感神经作用对人体其实是有害的,例如血压升高,注意
力不集中等等)
(1) a L-CHO diet is detrimental to anaerobic work capacity, possibly because o
f a reduced muscle glycogen store and decreased rate of glycolysis; (2) reduce
d carbohydrate intake for 3 days enhances activity of the sympathoadrenal syst
em at rest and after exercise.
第五篇提到的论文:Relative effects of glycogen depletion and previous exercise
on muscle force and endurance capacity
由于图书馆没买到相关期刊,无法阅读全文,
只能看研究设计前面的部分
文中提到:
运动前完全不摄取碳水化合物,或过量的摄取碳水化合物,都可能会让肌肉持久力下降
Endurance capacity of human vastus lateralis muscles was observed 24 h after h
ard exercise followed by either a carbohydrate-restricted or a carbohydrate-lo
aded diet (depletion and repletion conditions). In a control condition the sub
jects did no previous exercise and ate their normal diet. Each of these condit
ions was followed by an experimental protocol in which the five male subjects
made a series of alternating 25-s static contractions of each leg at 50% maxim
al voluntary contraction until one leg failed to achieve the required force (T
lim). Glycogen concentration before the experimental protocol in both legs was
significantly lower in the depletion than in the repletion condition. Muscle
lactate and creatine phosphate concentrations were within normal limits before
the static contractions. The number of contractions the repleted (12.7 +/- 2.
2) and depleted (10.3 +/- 1.5) legs could sustain before Tlim were not differe
nt from each other, but both were 35% (P less than 0.05) fewer than the contro
l (17.6 +/- 3.0).
欢迎各位帮忙补充这paper的内容
第六篇提到的论文:Interactions of cortisol, testosterone, and resistance train
ing: influence of circadian rhythms.
嗯,的确没错,大部分人傍晚时训练的状况其实较好
第七篇:Changing concepts on the control of growth hormone secretion in man.
这篇完全没提到“为什么吃高GI碳水(化合物)”
整篇Article都在论述生长激素(Growth hormone),标题早就一目了然告诉读者这篇不是
在讲高低GI饮食
第八篇:Intracellular mechanisms underlying increases in glucose uptake in res
ponse to insulin or exercise in skeletal muscle.
的确没错,运动能增加Insulin hypersensitivity,能有效的帮助降血糖
本文没有要引战的意思,
我起初看到你po的文,想说很有心贴出这么多论文标题,就打算每篇找出来确认后真实性
后再佐证你的看法,
没想到事与愿违。
本篇打脸文重点:
没证据显示完全不吃早餐、训练前完全低碳饮食、高GI食物能有效减脂增肌
当然,没证据显示不代表一定不行,但仍欢迎提供相应的证据出来供大家参考及讨论
