Your science teacher is a *********.
Running is bad for your knees if you do it too much (for some people) because it puts pressure and alot of force on your knees constantly, knees are usually weak in most peolpe. If you go on the bike that is a whole other story, just like swimming, is great beause it doesn't put any force or strength on a certain part of your body so you can do that without any problems.
You should do alot of little sprints, suicides, squats and lundges. This is called interval training, you run for a bit, then for 1 minute, you sprint as hard as you can, then you slow down, and in a couple minutes you do it again. You should do that on a bike.
If your in the gym by yourself then you should do suicides, that is the best thing to do, and during rests you should do squats and lundges beacuse that will strengthen up your glutes, quads etc, and all the fast-twitch fibers in your legs that are needed for sprinting and jumping.
If your a good jumped, you should be a good sprinter as well.
