I use to research this stuff (increasing your vert) years ago...
From what I gathered, when you do squats, instead of coming up slow like a BodyBuilder would do, you must make a quick "explosive" movement. Thisactivates a different Twitch Fiber.
Instead of doing 8-12 reps like a BodyBuilder would do, use enough weight so you can only do 5-8 reps.
The reason I keep mentioning "bodybuilder" is becaue they train for hypertrophy (muscle size), instead of strength/power/speed.
As for the calf raises, you should do them on one leg to increase the resistance. And I'm not sure if it actually does anything, but when I do them with myfeet facing outwards instead inwards, it seems to hit a different area of the calves.
