I would like to know how I can increase my speed in BALL hockey. In the last few months I've been doing running, anywhere from 2Km to 5km. I take a 10-minute break and do sprintings like two 200-meter sprintings (38 seconds each) and four 25meter-sprintings (4.2 seconds each). That running has been making a great difference in my playing since I can run faster and longer because my muscles no longer hurt that much and I'm not that much out of breath anymore. Are there specific exercises I should do to run even faster? Thanks!
