Answer 11

30-40%

Question 12

Explain the mechanism of exercise on reducing type 2 diabetes risk?

Answer 12

exercise is a potent stimulus of muscle glucose and TAG uptake due to increased energy demand of activity

• skeletal muscle plays important role in regulating storage and/or oxidation of glucose and TAG during the postprandial period
• insulin plays central role in this regulation
• reductions in peripheral insulin sensitivity lead to abnormalities in glucose and TAG metabolism

Question 13

What are the effects on an acute bout of exercise?

Answer 13

• increased glucose transport into muscle
• insulin-stimulated glucose uptake is elevated for at least 16 hours
• glucoregulatory effect spans many meals (about 3 days)
• exercise is a potent and non-pharmacological strategy for increasing muscle insulin sensitivity and improving postprandial glucose control

Question 14

What are the exercise guidelines for adults aged 19-64 years?

Answer 14

• 150 minutes of moderate aerobic activity a week and strength exercises on two or more days a week that work all major muscles
• 75 minutes of vigorous aerobic activity and strength exercises on two or more days a week that work all major muscles
• mix of moderate and vigorous aerobic activity every week (such as two 30 minute runs and 30 minutes of fast walking) and strength exercises on two or more days a week that work all major muscles

Question 15

What aspect of exercise is thought to be the main determinant of the magnitude of improved glycaemic responses?

Answer 15

Question 21

What are some things that the future of diabetic healthcare will have?
