把下面的英语翻译成汉语

The reason, they suggest, is that the reactive oxygen compounds, inevitable byproducts of exercise, are a natural trigger for both of these responses. The vitamins, by efficiently destroying the reactive oxygen, short-circuit the body’s natural response to exercise.
“If you exercise to promote health, you shouldn’t take large amounts of antioxidants,” Dr. Ristow said. A second message of the study, he said, “is that antioxidants in general cause certain effects that inhibit otherwise positive effects of exercise, dieting and other interventions.” The findings appear in this week’s issue of The Proceedings of the National Academy of Sciences.
The effect of vitamins on exercise and glucose metabolism “is really quite significant,” said Dr. C. Ronald Kahn of the Joslin Diabetes Center in Boston, a co-author of the report. “If people are trying to exercise, this is blocking the effects of insulin on the metabolic response.”
The advice does not apply to fruits and vegetables, Dr. Ristow said; even though they are high in antioxidants, the many other substances they contain presumably outweigh any negative effect.
Dr. Kahn said it might be that reactive oxygen is beneficial in small doses, because it touches off the body’s natural defense system, but harmful in higher doses.
Andrew Shao of the Council for Responsible Nutrition, a trade association of dietary supplement makers, said the new study was well designed but was just one bit of evidence in a complex issue. Most available evidence points to the opposite conclusion, that antioxidants benefit health by reducing oxidative stress, he said.
“I wouldn’t change recommendations for anyone based on one study,” he said. “This is one small piece of the puzzle.”

研究人员表示,原因是因为活性氧化合物--这种锻炼过程中产生的不可必免的副产品,是这两种机能反应的天然引发剂.维生素通过破坏活性氧,使人体不会对锻炼产生自然的反应.

"如果你想要通过锻炼来促进身体健康,那你就不应该服用大量的抗氧化剂,"迈克尔博士说."这项研究的第二个启示就是,抗氧化剂通常会产生某些影响,它们会抑制锻炼、饮食和其它调节活动的积极作用."这一发现刊登在本周出版的美国国家科学院期刊上.

维生素对锻炼和糖代谢的影响"真的非常重要,"波士顿乔斯林糖尿病研究中心的罗纳德博士说道,他是此篇报道的合著者之一."如果人们正在尝试去锻炼,这种作用就会阻碍胰岛素对代谢反应的影响."

这条建议并不适用于水果和蔬菜,迈克尔博士说,尽管它们的抗氧化剂含量很高,但它们含有的许多其它物质想必胜过任何负面影响.

卡恩博士说"也许小剂量的活性氧是有益的,因为它激发了人体的自然防御系统,但更高的剂量就是有害的."
可靠营养品协会（生产膳食补充品的商贸协会)的安德鲁.邵说:"这项新研究是精心设计的,但它只是整个复杂课题中的一个小小的证据.大多数现有的证据指向了相反的结论，即抗氧化剂通过减少氧化应激促进健康."

"我不会因为任何人做的单独一项研究而改变想法,"他说,"这只是整幅拼图中的一小片."

原因，他们建议，氧气混合物反作用，以及在锻炼中产生的不可避免的副产物。是这两个反应的一个自然的诱发因素。维生素，通过有效地破坏没用的氧 ，使身体的自然的反应短路锻炼 ，“如果你锻炼促进健康，你不应该使用过量的抗氧化剂 ”Dr. Ristow 说，研究中的第2条消息 ，他说：“那抗氧化剂在一般原因内是不会这样抑制练习的，忌食和其他负面的影响的会有个效应 。”结论在这星期的国家科学院的诉讼的发行过程中出庭。

维生素对锻炼的影响和葡萄糖新陈代谢"确实重要"， Joslin糖尿病中心的Dr. C. Ronald Kahn 在波士顿，报告的合著者说。 "如果人们试图锻炼，这是正堵塞胰岛素对代谢反应的影响"。

建议不要用于水果和蔬菜，Dr. Ristow 说； 即使他们在抗氧化剂内高，他们包含的很多其他物质也大概超过任何负的效应。

Dr. Kahn说，天气可能是无功氧在小剂量内有利，天气发射身体自然辩护系统，但是在更高的剂量内有害。 天气可能是无功氧在小剂量内有利，天气发射身体自然辩护系统，但是在更高的剂量内有害。

负责任的营养的委员会的Andrew Shao ，饮食补贸易协会充的创造者说，新研究设计不错，但是存在一个复杂的问题。 大多数可得到的证据指向相反的结论，通过降低氧化的压力的抗氧化剂，这样更有益于健康，他说。

“我将不基于一项研究为任何人改变建议，”他说。 "这是一个小谜团。”
