I commented a few months back about how adrenaline during a Judo tournament severely spiked my blood sugar. It doubled to nearly 400 after just a few minutes of fighting. It appears it may not have been all the adrenaline's fault. I was taking an antibiotic "doxycycline" at the time and it may have also been to blame. Apparently I have an allergy to the serum in that family of antibiotics. But nonetheless, I had another Judo tournament over the weekend and monitored by blood sugar very closely before and after fighting. My blood sugar barely changed after my fights, even though I was just as nervous or more nervous beforehand this time. A few things I did notice though were while waiting for my first fight, the adrenaline would come in waves, so I jumped rope or jogged around the gym when I felt the nerves coming on. This helped to relieve the bad feeling and kept my blood sugar under control. I know the adrenaline or cortisol played a part in my blood sugar though because I barely ate anything all day and I stayed at a consistent 185 for most of the day. A little high but manageable. I did some studying on how to control adrenaline before a fight and the hints I picked up really did help. Learning to manage the adrenaline is vital to performance because it can ruin you if you let it. I did not tire out as quickly this time and was more clear-headed during the fight. I can actually remember most of it and I won a very nice, although not uncontested, gold medal.
