I am type 1 diabetic and I was diagnosed when I was 26, active duty military and in the best shape of my life. Type 1 means your pancreas does not produce insulin, you can be diagnosed at any age. They used to refer to it as juvenile diabetes because it was mainly diagnosed in children, that is beginning to change so they have started calling it type 1. I jump with it, but I just check my sugar a lot, and eat as needed. The adrenaline speeds your metabolism up so account for that as well. It could cause any recent insulin you have given yourself to metabolize quicker, leading to a low. of course you can jump, you just have one more thing to remember when getting ready! Have fun
