I think I meant “elastic” strength instead of eccentric because I was trying to get my jumps [b]higher[/b] in the long jump. Does it matter which one it is? And is there a way to just stop getting shin splints?
Until you get your shins in order, you could do jump squats. Just don’t toe off. Basically push explosively but don’t raise up on your toes. You can control this by adding enough weight to keep you from leaving the ground. When your shins are better, you can return to jumps.
