Wasn't Lydiards main point that too much lactic acid over too long of a period would eventually cause the blood ph to drop, thus affecting metabolism? I believe also that he thought that buffering against the effects of lactic acid could be accomplished within a 4-week time period, and that doing fast intervals during the buildup phase would only take away from aerobic development. I'm no Lydiard expert, so correct me if I am wrong.
Thus, according to Lydiard, your son's coach is doing the right thing. N'est pas?
