Preparing For Exercise
Proper warm-up consisting of 5–10 min of aerobic activity
Activity session 15- 30 mins
cool-down should be structured similarly to the warm-up and should last about 5–10 min
Types of Physical Activity
The Mnemonic: “SAFE” exercises are recommended:
Strengthening exercises Aerobic exercises Flexibility exercises Endurance exercises
Aerobic exercise
With Oxygen Aerobic exercise is the type
that moves large muscle groups and causes you to breathe more deeply and your heart to work harder to pump blood. It's also called cardiovascular exercise. It improves the health of your heart and lungs.
Anaerobic (Resistance) Exercise
Anaerobic exercise uses large muscles that do not require oxygen for short periods of exercise. It helps build strong muscles; lowers blood glucose makes the action of insulin more effective.
Flexibility (Stretching) Exercise Flexibility exercises
are aimed at increasing or maintaining range of motion at joints, also improve tone in muscles and keep it supple. They develop better muscular and body control.
Endurance Exercises
Low Resistance, High Repetition Exercises
Examples: Walking, cycling,
swimming, or upper extremity ergometry that involve the use of the large muscle of the body.
How much exercise?
Exercises should be done according to FITT principle. FREQUENCY: Exercising 4 to 6 times a week. INTENSITY: 30-40 min of exercise at 50- 60 % of
target heart rate. TYPE: SAFE exercises are recommended. TIME: Morning is ideal

Warm Up Target Zone Exercising Cool Down Time Total
Week 1
Session A Walk normally 5 min. Then walk briskly 5 min. Then walk normally 5 min. 15 min.
Session B --Repeat above pattern--
Session C --Repeat above pattern--
Continue with at least three exercise sessions during each week of the program. If you find a particular week's pattern tiring, repeat it before going on to the next pattern. You do not have to complete the walking program in 12 weeks.
Week 2 Walk 5 min. Walk briskly 7 min. Walk 5 min. 17 min.
Week 3 Walk 5 min. Walk briskly 9 min. Walk 5 min. 19 min.
Week 4 Walk 5 min. Walk briskly 11 min. Walk 5 min. 21 min.
Week 5 Walk 5 min. Walk briskly 13 min. Walk 5 min. 23 min.
Week 6 Walk 5 min. Walk briskly 15 min. Walk 5 min. 25 min.
Week 7 Walk 5 min. Walk briskly 18 min. Walk 5 min. 28 min.
Week 8 Walk 5 min. Walk briskly 20 min. Walk 5 min. 30 min.

Week 11 Walk 5 min. Walk briskly 28 min. Walk 5 min. 38 min.
Week 12 Walk 5 min. Walk briskly 30 min. Walk 5 min. 40 min.
Week 13 and thereafter:Check your pulse periodically to see if you are exercising within your target zone. As you get more in shape, try exercising within the upper range of your target zone. Gradually increase your brisk walking time to 30 to 60 minutes, three or four times a week.

Hypoglycemia Management
The person should be instructed to stop exercising. People at risk for hypoglycemia should always carry a source of glucose with them such as glucose tablets, candy or juice in order to treat hypoglycemia.
Remember- it is a medical emergency
Snacking to prevent hypoglycemia
Basic Rules: Snack prior to activity to prevent hypoglycemia
Adjust quantity based on pre-activity BG or direction of BG
BG low or dropping: usual carbs BG OK or stable: usual carbs BG High or rising: usual carbs
Snack at least once per hour during prolonged activity
Choose high-glycemic forms of carbohydrate

Useful Tips For Exercise Always carry an
identification card with you
Check your feet before you walk
Choose good footwear, light clothing
Drink lots of water
Don’t exercise during hot seasons, and when not feeling well

What Can Physical Activity Do For You?
Improve blood glucose control
(lowers A1C)
Physical activity lowers blood glucose in type 2 diabetes by helping:
muscle cells become more sensitive to insulin keep the liver from producing too much glucose build more muscle you lose weight and keep it off
What Can Physical Activity Do For You?
Keep your heart healthy
Physical activity helps your heart by:
Strengthening heart muscle Lowering resting heart rate Lowering blood pressure Improving cholesterol Reducing risk of heart attack and stroke
“Sitting” through life increases your risk of:
heart disease high blood pressure high cholesterol overweight type 2 diabetes
We now must plan physical activity into our schedule
Getting Started
Check with your doctor if you: Are over age 35 Have had diabetes more than 10
years Have high blood pressure, heart
disease, poor circulation, or other diabetes complications
Aerobic Activity Walking briskly Dancing Bicycling Hiking Jogging/running Skating Stair climbing Swimming Water exercise
Resistance Activities
“Push, Pull, and Lift” Activities increase muscle strength prevent falls increase mobility improve blood glucose control
Stretching
Improves your balance and coordination
Makes you more flexible Reduces stiffness Reduces your risk of injury
How Can You Begin?
Choose activity (example: brisk walking)
Set a long-term goal - at least 30 minutes a day, 3-5 days a week
Buy comfortable walking shoes Get a partner
