I find that sometimes when I'm sparring, particularly if I'm sparring someone around my own level of ability, I can get quite riled up - particularly if I take a heavy hit. This gives me a serious energy boost: I'll throw more techniques, faster and harder. It also makes me more reckless: I'm more likely to take a hit if I think it will lead to an opening. My techniques, and more worryingly, my tactics, get sloppier. My footwork suffers.
Some of these results are good, some are bad, and some could go either way. I feel like there's a great deal of potential in harnessing this intensity properly: the increased speed and power I can manage when the adrenalin is really pumping is substantial.
Are there any mental techniques I can use to focus my emotions, to get more of the good results and fewer of the bad? Are there particular meditation techniques which can improve my control of this sort of thing? Or is this a dead-end, and I should find a less-emotive way to tap into my full potential?
