challenge for diabetics By MARK JOHNSONASSOCIATED PRESS WRITERALBANY, N.Y. --
During a game in her junior year, Ithaca College fieldhockeyplayer Sarah Gibble
knew something wasn't right."I started to feel very out of sorts, almost to the
point of gettingconfused,"she said. "Nothing was really working for me. I kept
fumbling with theball."Gibble, who has type 1 diabetes, left the game and tested
her blood sugarlevel- well below normal. Some juice and a granola bar got her
back on the field.She continued to play through her senior year, dealing with
the challengesfaced by thousands of athletes with diabetes. While exercise is
beneficialfordiabetics, helping to stave off complications and control blood
sugar, ittakesplanning and care to participate safely.Former NBA center Chris
Dudley, golfers Scott Ver!
  plank and Kelli Kuehne,Olympic swimmer Gary Hall Jr. and Hockey Hall of Famer
Bobby Clarke areamong along list of accomplished diabetic athletes.Around
800,000 people have type 1, or juvenile, diabetes in which thepancreasproduces
none of the blood-sugar regulating insulin. Type 1 diabetics needtotake daily
injections or use an insulin pump.Most of the nation's 18 million diabetics have
type 2, or adult-onsetdiabetesin which insulin is still present, but isn't used
properly by the body.Obesity,high cholesterol, high blood pressure, physical
inactivity and familyhistoryare all risk factors for type 2. Treatments include
diet, oral medicationandinsulin shots.The most common problem for type 1
diabetics is hypoglycemia, or low bloodsugar.During exercise, the body depletes
its stores of sugar, then cuts insulinproduction to compensate for the lower
sugar levels. But in people takinginsulin shots or using a pump, that doesn't
happen. Instead, hypoglycemiasetsin, causing symptoms!
  including dizziness, sweating, confusion andnervousness.Untreated, a 
 person can lose consciousness, become comatose or even die.Taking too little
insulin can cause problems for an athlete too, said Dr.JamesDesemone, director
of the Goodman Diabetes Service at Albany Medical Center.During physical
activity, the body releases hormones like adrenaline thatcounteract insulin.
That increases bloodstream levels of glucose andketones,byproducts formed when
fat is burned for energy, which can be dangerous.Diagnosed with type 1 diabetes
30 years ago, Desemone works with manyathleteswith diabetes, from hockey players
to cyclists.The key, he says, is setting up a regimen using insulin injections
or a pumptomimic the functioning of a normal pancreas during exercise, adjusting
howmuchinsulin is given to the body and when. Drinking enough liquids is
alsoimportantto maintain correct blood sugar levels, he said.Paula Harper, 61,
started the Diabetes Exercise and Sports Association in1985,a nonprofit group
with about 3,000 members in North America and Europe.!
  Alongtime runner and nurse who has competed in 35 marathons, Harper
wasfrustrated trying to come up with the right formula to keep her blood
sugarlevel up over long distances."When I started, it was all trial-and-error,"
said Harper, a diabetic since1972. "And trial-and-error can get you in trouble
sometimes."She recalled races when she ate a Fig Newton every two miles to keep
herbloodsugar up, and with the help of her husband, pricked her finger every
fivemilesto test it.A recent National Institutes of Health study showed that 58
percent ofpeoplewith pre-diabetes - where blood sugar is elevated but not to the
level oftype 2diabetes - staved off type 2 diabetes by exercising moderately 30
minutes adayand by cutting their weight by 5 to 10 percent."I so firmly believe
exercise is important for everybody, but especially fordiabetes," Harper said.
Her organization is "trying to help people with type1exercise safely and give
those with type 2 the motivation to get off thecouch!
