Michael Johnson, when he's commentating on Sanya Richards doing the 400m in around 49s, always says that you can't sprint flat-out for 400m and you have to relax and maintain along the back straight. And he's got to be the guru, right?

See, I know how good sprinting is for you, but it makes me feel so terrible I'm reluctant to do it. Did it a couple of weeks ago with my 9-year-old as a rabbit (I never caught her!) doing 4x30s with 4mins recovery in between, and afterwards I felt so sick I had to miss having my tea!
A couple years ago, after being what I thought was very thoroughly warmed up, (I had hiked extensively a bit earlier in the day,) I took a Karate class and while executing front kicks, to my disappointment and surpirse, badly injured a hamstring.) Although I want to preserve the ability to sprint if ever necessary, (thinking more life and death than catching a train, for example,) for training situations I have now leaned in the same direction as you ecole66. I've done "sprints" with: Heavybag, rebounder, squat/row movements with resistance bands and, IME, the most brutal, the Scwinn Airdyne.
The best thing is to start out gradually and build up intensity. Sprints are not supposed to be a nice walk in the park, so if you want great results, continue to sprint, just remember that things must proceed gradually! Right now I have injured a tendon in one of my calves, so my stair sprints cannot be an all-out effort these days, but I still jog up the stairs…
