I'm not sure if you know or not but us diabetics make good scientists with all the experimenting we do. I mean, every day is an experiment.
I did some stair reps last night. I tested my blood after the third rep and was worried it would go too low before I got a chance to finish my work out and maybe I would have to down some glucose. So I went ahead and wasted a bunch of strips and did an experiment. Keep in mind I had my temp basal pre-workout set at %25 for an hour ahead of time.
Here are my findings:
Before I started I was 9.9mmol/l (180mg/dl). I ate a few candies because I had a little bit of insulin on board and I like to be higher than that for the stairs. Also, the stairs as I mentioned in a post awhile ago are 330steps. It's approximately 4 minutes up, 3 minutes down totalling 7 minutes per rep.
After 3 reps I was at 7.7 (138)
After rep #4 I was at 7.2 (130)
rep #5 6.9 (124)
rep #6 6.6 (118)
rep #7 6.3 (113)
rep #8 6.0 (108)
My Conclusion? For every 7 minutes of stairs my blood sugar drops an average of 0.36 mmol/l (6mg/dl). Therefore, working backwards for example, if I want to do 10 reps of stairs, and I want my finishing blood sugar to be 5.0 mmol/l (90mg/dl). Taking into account my temp basal is at 25% for one hour prior:
(0.36 X 10) + 5 = 8.6 mmol/l
(6 X 10) + 90 = 150 mg/dl
Starting blood sugar needs to be at least 8.6 (I can't forget the few candies I ate beforehand, they must have played a role in there somewhere) Either way, not bad for an hours worth of cardio. I'm really glad I did that. The next experiment I'm going to do is running. I'm going to test after each km and see what I can come up with as a solution!
