Just wondering if this is normal... we've finally started some lighter sparring and a few days ago I did my first pass where we increased the tempo some. It was fun as hell but I got hit a lot more than I hit the other guys (except when they let me do stuff). Especially after getting very tired, I must have been shambling around like a zombie half the time. But dang it was fun! We kept at it for about an hour and a quarter with only very short pauses. I drank a liter and a half of water, got a minor bloody nose, sweated like a pig and ended up on my back a few times (footswept and taken down), but wasn't knocked out or groggy.
So anyway, the next day I'm headachey, felt weak and shaky, slightly nauseous sometimes and heavy and dull in my head. Supposedly these are classic dehydration symptoms and maybe exhaustion as well. Being new to it all I wondered if I'd gotten a concussion but I don't think any of the hits were really more jarring than heading a football. Also I felt fine right after the pass, just normally tired. Another thing is that I'd done 3 very tiring sessions on alternating days just before this. I'm almost 40 and not athletically conditioned. (working on it)
Two days later I felt pretty much better, but am a little apprehensive about going to a similar session. Is this normal? Is it a warning sign, like take it easier maybe rest an extra day?
In any case I think I'm going to try to keep the tempo down for the time being to try to get better technique. It's just so easy to get caught up in a higher tempo than I'm maybe ready for (I'm talking like maybe 30% instead of 10% here guys).
Any input to this enthusiastic but inexperienced beginner would be very welcome.
