Fasted training sprints?
I'm interested in the concept of fasted training, AKA 'train low, race high', and I've tried it out a few times.
It makes sense to me that you could improve the efficiency of your metabolism and more easily switch to fat burning during a longer race, possibly reducing the effect of the dreaded 'bonk'.
But I've recently begun to realise I enjoy speed much more than endurance. I'd like to bulk up and be able to sprint very fast. Would fasted training be any help with this?
My understanding of the first explosive burst of speed during a 100 meter sprint, is that it is anaerobic, and uses the energy stored in the muscles. Obviously you need glycogen-loaded muscles for a race, but would sprint training in a fasted state make the muscles able to store more or be more efficient somehow? Or does effective explosive training require super-fuelled muscles?
