CNS fatigue; what is that exactly? Sounds like a posh new word for knackered, or the slightly more scientific term, over-training.
you should be knackered after training, certain sports are very hard to 'over train' if you eat well and get rest but with sprinting you can do that right but still over train depending on how hard you go. you cant do a full on sprint, you work on diff pieces of the jigsaw, its only a small jigsaw with a few pieces, but if you put it together too quickly...
...that anology is going nowhere, basically you work on the start of the sprint and a sprint that is half the full distance of that event, then you work on the sprint endurace, you do the full sprint at race pace less often, that requires the most rest. if you go at 101% too often it wears you down and you go backwards. roadies/endurace riders have their 'shut up legs!', track sprinters have their 'shut up body!', theres only so many times you can tell your body to f*ck off before it says it back to you
