General
Exercise Tips For People With Diabetes
- The
more often you move your body, the more benefit you will get from it.
- How long you exercise is more important then how hard you "work out".
-
Wear
medical identification bracelet or necklace at all times.
-
If you take insulin or are on certain diabetes pills:
- Be alert for hypoglycemia during and several hours after exercise.
- Carry
fast-acting carbohydrate during exercise and use to prevent or treat
hypoglycemia. Stop the exercise
at the first sign of a reaction and treat it. Do not keep exercising.
- Wear
supportive shoes and comfortable clothes.
- Shoes & socks: Be sure you exercise with new socks (to prevent blisters) and
appropriate shoes that are properly fitted to provide good support to your
feet.
- Clothing: Clothes should allow freedom of movement. Wear layers if it's cold outside and don't forget hats and gloves.
In hot weather, light-colored, loose-fitting clothes are best. The fabric closest to your skin should be chaff-resistant.
-
Avoid the risk of dehydration (which may be a problem when blood glucose control
is less than desired) by taking extra fluids or by skipping exercise on particularly hot days.
-
Choose
activities you enjoy and can perform safely.
-
Let
your exercise partner, or if you play a team sport, another team-mate know
of your diabetes. Educate them
about any help you may need. If
you exercise alone, let someone know where you went, and when you expect to
be back.
Parts
Of An Exercise Routine
Type: The kind of activity you choose to do. Your routine may include activities for
flexibility, aerobic conditioning, or muscle strengthening.
Frequency: How often you do the activity. Daily exercise is best for diabetes,
especially those on medication because of the balancing of food and medication.
Exercise three to five times a week will give cardiovascular benefit from
aerobic activity.
Intensity: How hard you do the activity. The
correct intensity of exercise depends on your fitness level. Start at the level
you feel comfortable with.
Duration: How long an exercise session lasts.
Developing Your Exercise Plan
An exercise plan includes three important parts:
The warm up, the work out, and the cool down.
-
The warm-up: This is extremely
important in preventing injury to your muscles. The best warm-up is to actually do the exercise you will be doing at
a slow pace for ten minutes.
-
The work-out: The portion of
the exercise when the muscles are working and sugar is being used for fuel.
Choose an activity the you enjoy (walking, swimming, tennis, biking,
hiking, etc).
The appropriate intensity of exercise for the "work-out"
portion of your exercise is in the "fairly light" to
"somewhat hard" area (see the scale below).
|
Perceived
Exertion Scale
very, very
light very light fairly
light somewhat
hard hard very hard very, very
hard
|
Another general guide for the right level of intensity is the "talk
test". You should still be able to carry on a conversation while you
are "working out".
- The cool-down: Take ten minutes from the time you finish your
work-out to let your body return to normal. Continue to do the same activity
at a slower pace so your body recovers from the exercise. This will prevent
sore muscles and dizziness.
Example of Starting an Exercise Plan:
If your goal is a non-stop walk for at least 30
minutes every day, you need to gradually work up to this goal. Start by walking 5 minutes every day for 3 days, then add 5 minutes to
walking time every two days until you have worked up to your goal.
Avoiding
Low Blood Sugar When Exercising
Since
less insulin is needed during exercise, if you take a sulfonylurea drug, Prandin,
Starlix, or insulin injections, your BG may drop too low with exercise.
-
Carry
fast-acting carbohydrate with you at all times. Be alert for signs and
symptoms of hypoglycemia (low blood glucose).
If it occurs, treat it and stop exercising.
-
The best time to exercise is 30 - 60 minutes after a meal, depending on the
intensity of the exercise.
-
If you are exercising more than an hour after eating, eat some carbohydrate
before you start. Usually 15-30
grams is enough for a half hour of moderate or an hour of light activity.
-
Extended strenuous exercise (cross-country skiing, hiking) can deplete your liver
stores of sugar. In this case,
you should double your bedtime snack that night. Often this will prevent hypoglycemia during the night or the
following morning.
