Question

i dont get how people in the olympice get like 3:30 on the 1500 meters and then the next four years, they do worser or better by 1 sec. how can you only improve by a little in 4 years.

Answer 1

Once you get to a point of being that fast, it's extremely hard to drop times.   That's why it takes so much to break a world records and why not just anyone can break them.

Also sometimes they have bad races.  They also could have suffered injuries during the four years.  Shorter distances like that, age has a lot of impact on it.  They aren't getting any younger and they're still receiving the harsh impact of running.

Answer 2

Sometimes you just have a bad race. Sometimes your body reaches it's top peak potential and then you can only match or do lesser than you did before.
