请帮忙翻下这段话，雅思6阅读第一篇的一段A lot of their work es down to measurement-everything from the exact angle of a swimmer's dive to the second-by-second power output of a cyclist.This data is used to wring improvements out of atheletes.The focus is on individuals,tweaking performances to squeeze an extra hundredth of a second here,an extra millimetre there.No gain is too slight to bother with.

【答案】 归结到底，他们的主要工作是以潜水项目严谨的角度来逐秒测量一个自行车运动员的能量输出数据。这些数据是用来开发运动员的潜能，对于他们来说，奋力拼搏，随时随地去争取每一个百分之一秒和每一个毫米是十分关键的。因为轻视微不足道的进步而不去费心，最终将一无所获。
