Back in 2015, Red Bull took their athletes through a series of “fear exercises” to help them perform better under pressure.
回顾2015年，红牛车队（奥地利一级方程式车队之一）带领队员经历了一系列“恐惧训练”以帮助他们在压力下激发更好的表现。
They had to drive racing cars on a dirt track, hold their breath under water as long as possible, and even crawl through a tunnel filled with snakes. At the end of the “fear training”, the athletes measured their heart rate, blood pressure, and mental comfort.
他们要在一条很脏的赛道上开赛车，在水下尽可能长时间憋气，甚至要爬过满是蛇的地道。“恐惧训练”结束后，队员测了心率、血压和精神舒适度。
Guess what happened?
猜猜结果怎样？
They were able to move faster, they were able to think faster, and they were able to act faster. Most importantly, their brain and body adapted under pressure. What was first a mentally exhausting and stressful activity, became something that they could do with ease and much more quickly.
他们移动速度更快，思维更敏捷，反应也更迅速。最重要的是，他们的大脑和身体适应了压力下的状态，原本是耗费脑力和施加压力的活动，反倒让他们能轻松应对，并且完成速度更快。
