The idea seems sort of foolish, just another exercise trick. Stand for a few minutes on a platform that vibrates. Get off and try to do some weight lifting. Or see how high you can jump. You are【C1】______supposed to be able to lift heavier weights and jump higher.
But maybe it’s not so【C2】______, exercise experts say. Although they don’t really know why vibrations should work, researchers report that they actually seem to slightly improve【C3】______in the few minutes after a person gets off the machine.
The problem,【C4】______, is that there is little【C5】______on how fast the vibrations should be or in what direction platforms are【C6】______to vibrate. Some studies have【C7】______to show any effects from vibrations. And then there is the question of【C8】______exactly vibrations are doing to muscles and nerves.
"It【C9】______is arousing interest, and a large portion of the【C10】______would support that something is happening," said Lee E. Brown, an expert at California State University. But he added, "We are still trying to【C11】______exactly what the mechanism is."
Meanwhile, several companies make the vibrating platforms, and they are being used at gyms and【C12】______some athletes. One company, Power Plate,【C13】______that stars like Serena Williams and Justin Morneau, of the Minnesota Twins, train with its【C14】______. Another company, Wave, says the United States ski team used its vibrating plates in training【C15】______the coming Winter Olympics.
But researchers are【C16】______. "There is something to it," said William J. Kraemer, a professor at the University of Connecticut,【C17】______it "another tool" for athletic conditioning. But he added that other conditioning methods might【C18】______the same or better results. Researchers say, people should be appropriately skeptical about the effects of standing on a vibrating platform. "We don’t know a lot about prescribing it," Dr. Kraemer said. "There’s the【C19】______. Research is trying to【C20】______up."
【C16】
选项
A、alert
B、controversial
C、confused
D、confident
答案
A
解析
上下文语义题。句首的But表明本句与上文存在转折关系,上一段提到运动员用振动机来训练,暗示该仪器的确具有一定的效果,本句应与此意相反,且结合本段下文提到的“研究人员说人们应该对振动机的效果保持适当的质疑”(skeptical about)可知,本段内容是对振动机效果的怀疑,故填入A项alert,表示“研究人员很警惕”。
