常春藤生活英语【41】Pedaling to Health踏向健康（在线收听）

One of the most famous bike makers in the world is Taiwan's own Giant. When Giant started in 1972 in Taichung, it only produced bikes for bigger companies like Schwinn. In 1986, Giant decided to compete in the high-end bikes business because the market was expanding quickly. Now, Giant has over 10,000 stores around the world and sells more than three million bikes every year.

People in Taiwan are finally living up to the name "Bicycle Kingdom." Lately, more and more cyclists have been seen on the streets. Friends or families often ride together in mountains or along rivers during the weekends.

Riding a bike is great exercise for everyone. The amount of calories that you burn depends on how hard you pedal and how much you weigh. For example, if a woman that weighs 50 kilograms rides for one hour at a relaxing pace, she would burn 500 calories. If she decided to race with her friends the whole time, she could double that number. The same thing applies to men. If an average man that weighs 70 kilograms rides casually for an hour, he would burn 450 calories. But if that same man decided to really push himself, he could lose up to 1,100 calories. To burn the same amount of calories through hiking, he would have to walk for three full hours without stopping.

世上最有名的自行车制造商之一便是台湾自产的捷安特。1972年捷安特于台中成立之初，仅为Schwinn等较大的公司制作脚踏车（编按：Schwinn 为美国的自行车制造商，1895年于芝加哥成立）。1986年，因为市场正急速扩大，捷安特便决定投入高级自行车业的竞争行列。如今捷安特在全球有超过一万家店面，每年更卖出超过三百万辆自行车。

台湾的人民总算不负『单车王国』的盛名。最近在街上看到了越来越多的自行车骑士。周末常有好友或家人结伴骑乘在山中或河边。

骑乘自行车对每个人来说都是很棒的运动。您燃烧的热量有多少，端看您骑得有多卖力及您本身的体重有多重。举例来说，如果一名体重五十公斤的女士以轻松的步调骑上一小时，她会消耗掉五百卡路里。若她决定这整段时间内都跟她的朋友比赛，她就能使燃烧的热量加倍。同样的结果也适用于男性。假如一名体重七十公斤的一般男性悠闲地骑上一小时，他会燃烧掉四百五十卡路里。但假使这名男子决定很卖力骑车，他能消耗多达一千一百卡路里。要以健行来燃烧等量的热量，他就必须一口气走上三个小时。
