Max Domi - NHL Hockey player is a Type 1 and I believe he wears a pump when he plays. Always wondered how the pump can withstand the hard physical contact of hockey but from what I was told he requires it because most hockey players are on for only a couple of minutes at a time - skate, hit and play like crazy and then are back on the bench with the next line change - talking about Adrenalin. He must use a special pump - getting hit by a puck that's going over 100 Km per Hour or getting crushed along the boards - gotta be a specially designed equipped pump.
I played as a kid - no pumps back in those days - so I never had an idea as to where my BG levels were at. Another hockey player who I always looked up too as did Max Domi was Bobby Clarke. He didn;t use a pump either and probably just went with it.
Anyway, interesting article on Max Domi - kind of like the part about his Helper Dog.
