关于游泳你可能不知道的5大真相

1. Why do Olympic divers use small towels？

为什么奥运会跳水运动员用小浴巾？

Olympic gold medalist Laura Wilkinson explains that the name of the little towel is called shammy. The shammy， made out of rayon or polyvinyl， can hold a lot of water and dry quickly， the former US diver reveals.

Divers use shammys in between dives to dry off， which prevents the diver from losing grip when competing.

前美国跳水运动员、奥运金牌得主劳拉·威尔金森表示，这个“小方巾”名为麂皮革。这种由人造纤维或聚乙烯化合物制成的麂皮革可以快速吸干运动员身上的大量水分。

运动员在每次跳水间隔期间都会用麂皮革吸干身上的水分，这样做可以避免他们在比赛时失去控制。

2. Why are there lifeguards at Olympic pools？

为什么奥运会泳池旁会有救生员？

You may think there is zero chance of Olympic swimmers needing lifeguards. But its necessary， according to a New York Times interview with Danielle Martelote， the lifeguard supervisor at the Olympic Aquatics Stadium. She mentions potential situations they would be needed in， such as if swimmers have debilitating cramps， heart attacks and head-crunching collisions into the wall.

Additionally， a Brazilian law requires lifeguards to be on-site at any swimming pool larger than 20 feet by 20 feet.

“Its a one-in-a-million type of event， but were prepared，” Anderson Fertes， one of the lifeguards， told the New York Times.

你或许会认为奥运水上运动员需要救生员的概率为零。《纽约时报》的记者曾就此对话奥林匹克水上运动场馆救生员主管丹妮尔·马特洛特，她表示，救生员在赛场上仍必不可少，并提到游泳运动员也可能发生严重抽筋、心脏病突发，以及头部撞墙的情况。

此外，巴西有专门的立法规定，面积大于400平方英尺的游泳池都必须配备救生员。

“虽然这种事发生的概率极小，我们还是为此做了充分的准备。”救生员安德森·费尔特斯告诉《纽约时报》的记者。

3. Why do Olympic divers get into the hot tub after competing？

为什么奥运跳水运动员在比赛后都要在热水浴池里泡一下？

The Washington Posts Jennifer Larue Huget asked former diver and sports psychology professor David Feigley why some Olympic divers dip in the hot tub after diving. Its simply because the water in the diving pool is chilly （which divers dont like） and the hot tub allows them to warm up， relax and focus， he explains.

《华盛顿邮报》的记者詹妮弗·拉吕·休格特曾就这个问题采访运动心理学教授、前跳水运动员大卫·费格利。后者表示，一些运动员在跳水后进入热水浴池仅仅是因为跳水池里的水很冷（这让他们感到不适），而热水浴池既能让他们感到暖和，又能让他们放松，并将注意力集中到下场比赛。

4. Why do Olympic swimmers splash water on themselves before they swim？

为什么奥运选手在游泳前要往自己身上洒水？

You may have noticed that some Olympic divers splash water onto themselves before competing. According to American swimmer Breeja Larson， “Your mouth feels parched before races a lot of the time. Thats why we splash.” Splashing water can also help swimmers acclimatize to the cold water.

你可能注意到了有些跳水運动员会在比赛前往自己身上洒水。美国游泳运动员布里亚·拉尔森表示：“大多数比赛前我们都会觉得口很干，这就是为什么我们会往身上洒水。”往身上洒水还能够让游泳运动员提前适应赛场的寒冷水温。
