One of the New Years' resolutions is to work through the backlog of fitness publications. Just got through a neat little book called Lactate Lift-Off. It's a laymen's guide to lactate handling. The author's contention is that "LT (lactate threshold) is the best-possible predictor of physical performance in all activities which last for two minutes or more."

Surprisingly, the book is already out of print. (It was published in '98.) I'm going to take a guess and say that the target audience of distance runners didn't like the message. To wit:

-long slow distance is counterproductive
-tempo training is mostly worthless
-heart rate training is mostly worthless
-"lactate zone" training is mostly worthless
-intensity invariably trumps duration
-VO2max has no predictive value for performance
-endurance runners should train like sprinters
-compound movement strength training is good
-high intensity circuit training is very good

This is all conventional wisdom for Crossfit adherents, but perhaps a bit too much to swallow for the pavement pounding crowd... Still, some good stuff here for the CrossFit athlete. For example, Anderson points out that LT encompasses both general metabolic qualities as well as sport specfic capabilities like efficiency/economy. It's easy to see from this that a well developed systemic ability to handle lactate can carry over to a variety of activities and can permit an athlete to be effective in areas that he hasn't specfically trained for.

I'd recommend picking up a copy, but I don't know where you can get one and can't remember where I got mine.

I tried to post a link last night, but apparently I am not capable from that machine. I think google will provide a site with a decent thumbnail of that particular theory.
