Glycaemic Control After A Single Exercise Bout And Chronic Exercise Training

Question 1

Effect of 1hr run on glucose transporter location

Answer 1

Exercise transiently increased concentration of glucose transporters in cell membrane

Question 2

Effect of AICAR perfusion on glut 4 translocation

Answer 2

AICAR increased glut 4 in translocation

Question 3

What are the effects of a single exercise bout on glycemic control

Answer 3

Single bout can transiently improve the uptake of glucose in skeletal muscle by a number of mechanisms:

Increased perfusion of active muscle increases exposure to target tissue

Increased expression of glut 4 gene

Increased glycogen synthase activity

Question 4

How could exercise training alter glycemic control

Answer 4

1.delivery of glucose and insulin to the muscle
2.amount of glut 4
3.glycogen synthase activity
