When I was doing my undergrad in Kines we had to write a "senior thesis" - 25 pages, but no experiments, so it was more like a large review of the literature. My topic ended up being "the effect of static stretching on athletic performance" as this was the point in time where lots of popular writers and researchers were arguing over whether or not static stretching before doing some sort of athletic activity reduced performance.
During my review it seemed that nearly all the studies which used sprinting as their marker of athletic performance reported decrements after static stretching, whereas nearly all the studies which used vertical jump as their marker of athletic performance reported no difference. I concluded that this effect may have been due to the fact that sprinting relies much more on stored energy than vertical jumping.
Long story short, it seems like an interesting thing to test, I can confirm there are tons of other studies in the literature that you can reference, and you could make it unique by testing both of these and comparing the results in a single study.
It requires virtually no equipment - just a vertical jump tester and a stop watch (or laser timer if you have one) and find a bunch of students to run and jump. The variables are simple so the data will be easily explained. You could probably make things more interesting by using exercises in the gym, but that will make the experiment harder and require more advanced equipment.
