Sprints

What exactly is a wind sprint?
Any sprinting/plyometric drills that someone can do to increase speed power and leg musculature?
As for weights ive got front and back squats cleans leg curls and maybe snatches?
thanks for any help

wind sprints are when you alternate sprints with jogging. so you would say jog for 40meters and the sprint for 20-40 meters then back to jogging and so forth.
