As an athlete I often hear people talk about alto rendimiento. I gathered an idea of what it meant by the way it is used. The meaning I extracted had to do with getting the most you can out of your abilities. Yesterday while browsing through the clothing section of Wal-Mart I saw a shirt that had the words performance and rendimiento on it.
Rendimiento is performance. It is also the yield that a recipe gives you.
also when something RINDE, it means it last long, or a little goes a long way.
