I have a question concerning lactate build up and the possible danger for kids by the build up. Now I have read that kids do not produce enough enzymes in their bodys to process lactate which could then harmful to their hearts and liver. Now I'm 35 years old and have been doing CrossFit for more than 2 years now and know that there are a lot of kids doing CrossFit (I think Conner from XFit BandX grew up with it and looks healthy to me). Are there any studies out there telling that anerobic workouts are not harmful to youngsters?

The last chapter of Starting Strength is an article by Lon Kilgore - a prof in exercise physiology. Does not address lactate buildup, but does address overall safety for anaerobic exercise.

His findings? Properly coached, anaerobic exercise is a good thing, and far safer than most sport activities kids are already involved in (e.g. soccer, basketball, hockey etc.)

IIRC, his bibliographic references, from standard peer-reviewed journals etc., stretch to a couple of pages.

My 3 kids CrossFit - either working with scaled versions of the WODs, or combining competitive rowing with anaerobic lifting.

The youngest (8) smokes us all.
