What is released in the body to replace low glucose?

Answer 22

Ketone bodies

Question 23

What are some general adaptations to endurance exercise?

Answer 23

Fatty acids are more easily mobilized from adipocytes, uptake of fatty acids into muscle cells is enhanced, number and size of mitochondria are increased

Question 24

T or F: Protein before or during endurance exercise has not been shown to improve performance over the consumption of carbohydrate alone.

Answer 24

True

Question 25

T or F: Consumption of protein after endurance exercise may help slow down or reverse the process of muscle degradation and may help recovery, particularly when combined with carbohydrates.

Answer 25

True

Question 26

T or F: It has been disproved that protein intake within 2-3 hours after resistance training is an important strategy for supporting skeletal muscle protein synthesis

Answer 26

False

Question 27

T or F: Protein intake >2.0g/kg/day is not associated with increased synthesis of muscle mass

Answer 27

True

Answer 29

Muscle glycogen- 1,500-1,200 kcals
Liver glycogen- 300-400 kcals
Blood glucose- 60-100 kcals
=2,500
