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."
【C12】
选项
A、in
B、by
C、beyond
D、between
答案
B
解析
语义逻辑题。空格前用了被动语态are being used,空格后的some athletes是used这个动作的发出者,被动语态中,用介词by引出动作发出者,故选B。
