I think the whole thought-process of going from one type of workout to another is the CNS fatigue associated with each. Int. Tempo has the least b/c it is run the slowest, and then split runs are increasing CNS fatigue and so on and so forth with SE1/speed endurance being the most demanding. It's all based on how things are planned. I think things would change, however, with a short sprinter, but I'm not for sure.
Well said :yes:.
