Interval training....with no intervals

If you take the rest intervals out of an interval session.....you get a single all out sprint.  Why do we assume you need to do lots of separate sprints?  Just because Tabata has become a training cliche? Would we get the same effects from a single hard sprint?  Why not?

Well at last scientists are starting to look at this idea.  If we want to keep things simple, lets start with one hard sprint before we start to add complexity.

Check out what James Steele has to say about this idea and the recent new research.

Simply Single Bout Sprinting

....and of course if a single sprint works, why not just do hard resistance training, working to sequentially recruit as many fibres as possible, taking the exercises to failure?
