Proliferative retinopathy, nephropathy or microalbuminurea

CAD, cerebrovascular disease, PAD, autonomic neuropathy, peripheral vascular disease

Question 3

What do exercise programs need in design?

Answer 3

Intensity, duration, frequency, mode, appropriate progression

Question 4

Describe warm up

Answer 4

5-10 minutes of alow activiry to gradually increase heart rate, blood flow, body temp, oxygen availability and breathing

Question 5

Decribe benefits of cool down

Answer 5

Prevent blood flow from pooling in extremities, removes metabolic byproducts

Question 6

Is it recommended for asymptomatic persons at low risk for CAD to get a stress test?

Answer 6

No

Question 7

Describe intensity exercise regimen

Answer 7

Moderate to vigorous
55-90% age adjusted max heart rate
40-85% max oxygen uptake or heart rate reserve

Question 8

Describe duration for exercise regimen

Answer 8

150 min per wk wth no less than 10 min per session

Question 9

Describe frequency of exercise regimen

Answer 9

Spread over 3 nonconsecutive days per week
No more than 2 consecutive days of inactivity
5 days per week most effective

Question 10

Exercise intensity of ___ to ___ of HRR (heart rate reserve)

Answer 10

40-85% which translates to 55-95% of max heart rate

Question 11

True or false:

Exercise performed at low levels (60% max heart rate

Answer 11

True

Question 12

What effects can vigorous exercise have on blood pressure and blood sugar

Answer 12

Transient hyperglycemia and rise in systolic blood pressure

Question 13

Formula for HHR (heart rate reserve)

Answer 13

Max HR - resting HR

Question 14

Formula for percent HRR

Answer 14

HRR x percent intensity

Question 15

Formula for % HR max

Answer 15

Max HR x percentage intensity

Question 16

Formula for target heart rate

Answer 16

((HRmax - HRrest) x desited percent intensity) + HRrest

Question 17

Target heart rate calculation

Answer 17

Eatimated hrmax = 220-age
Can be off by 12 to 15 beats per minute depending on the SD
can overestimate with type 2 diabetics, especially with autonomic neuropathy

Question 18

Alternate equation used to estimate target heart rate, especially in older population

Answer 18

Eatimated hrmax= 208-(0.7xage)

Uses 70% age

Question 19

Can you achieve the same cardiorespiratory gains in 3 short 10 minute workout versus 1 30 minute workout?

Answer 19

Yes

Question 20

Answer 20

60 m

Question 21

Why is regular PA needes for WL and glyemic control?

Answer 21

Duration of glycemic control after exercise session = 2-72 hours

Question 22

Intensity recommendations

Answer 22

Moderate to vigorous
40-85% vo2r or hrr
55-90% hrmax

Question 23

Resistance training precautions:

Microvascular macrovascular complications

Answer 23

Decrease strain on cardiovascular system

Question 24

Resistance training precautions:

Unstable proliferative retinopathy or severe nephropathy

Answer 24

Resistance training increased risk of excessive systolic blood pressure

Question 25

Dm or cvd patients can not have…

Answer 25

Ejection fraction

Question 26

Describe body effects when taking b adrenerg blocking agents in t2 dm patientss

Answer 26

Lower heart rate reaponse to PA

Mask hypoglycemic symptoms and lessen counterregulatory response
