I've had type 2 diabetes for awhile, but haven't been testing my blood for awhile at home because my A1c readings (A1c readings measure average blood sugar over three months time) have been good, and the A1c was the only thing a Nurse Practitioner who specialized in Diabetes cared about (she was my Nurse Practitoner). But lately I've been having symptoms that concerned me, so I started testing myself again. And I found doing martial arts for as little as ten minutes will lower my blood sugar 40 points! I was at 160 and after around ten minutes of practice I was down to 120! And even after eating a two scoop bowl of no sugar added ice cream topped off with whip cream, and than practicing martial arts for ten to twenty minutes my blood sugar went down to 104! I was practicing axe hand chops, chin jab upper cuts, low kicks,knee strikes to the groin, working up a good sweat. I encourage those of you who do have diabetes to practice martial arts to lower your blood sugar. And tell a diabetic friend.
