Hello, Insulin_John
I'm type1 too.
After I was diagnosed, I had once played Badminton for 2.5 hrs (not continuous). I strated on 2 hr after lunch and my blood sugar was not high about 100-120 mg/dl (sorry, i don't know how to change its to mmol/l)
In the evening, I injected and ate like everyday I did before.
But at night, My blood sugar was increase to 200-220 mg/dl, then I consulted to my personel
expert. he told me badminton is strong-impact sport that people in diabetes should not to play.
coz your mechanism know that you have to use much sugar for balancing.
so, it'll bring sugar in muscle , glycogen to go back to bloodsteam,
that why my blood sugar raised.
Now, when i want to exercise i'll walking , cycling instead of strong-impact sport.
Is he right?
sorry, if my language make you confuse, i don't good in Eng. - -"
