Diabetes and Physical Activity Flashcards
What are the recommendations for PA for adults and youth?
A: 150min/w = 20min/d Y: 60min/d mod-vigorous intensity no more than 2 days off strength training 2-3d/w
What are the 4 benefits of PA on diabetes?
- weight management
- reduced cardiovascular risks
- improved insulin sensitivity
- psychological benefits
Why does exercise lead to hypoglycemia?
no physiological decrease
What is GIR and what is it for?
Glucose infusion rate
To maintain euglycemia
Why are type 1 more at risk for nocturnal hypoglycemia after exercise? (4 things)
- increased glucose requirements
- impaired counter-regulation
- relative excessive circulating insulin
- absence of carb intake
What happens with insulin and fat due to exercise?
improves insulin sensitivity
better utilization of fat (leading to weight loss)
What type of exercise can cause hyperglycemia?
anaerobic
What type of exercise results in more stable glucose profile?
resistance training
What type of exercise can cause hypoglycemia?
aerobic
What kind of exercise can reduce the risk of hypoglycemia?
intermittent high intensity exercise that last 4-5s
or a 10s sprint
What are the warm up and cool down recommendations?
Warm up:
- if hyper, don’t exercise until hyperglycemia and ketones are restored with insulin
- if mildly hyper, do a 10-15min mild aerobic warm up
Cool down: always cool down fo 20min - aerobic, easy intensity
What is the bolus insulin dose reduction for 30 min of mild, moderate and heavy aerobic exercise?
mild: 25%
moderate: 50%
heavy: 75%
intense: none (why not?)
What is the effect on basal insulin levels if we disconnect the pump?
minimal effects if disconnected for a short period of time
What is the basal insulin dose adjustment before aerobic exercise for MDI and CSII?
MDI: reduce by 20%
CSII: reduce by 60-80%
What is the basal insulin dose adjustment after aerobic exercise for MDI and CSII?
MDI: reduce night time dose by 20%
CSII: reduce dose by 20% to 3am
