36. 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

37. Types of Physical Activity
The Mnemonic: “SAFE” exercises are
recommended:
 Strengthening exercises
 Aerobic exercises
 Flexibility exercises
 Endurance exercises

38. 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.

39. 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.

40. 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.

41. 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.

42. 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

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 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.

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

54. 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
