1-90 secs and its glycogen/CHO
|
|
How long is the Aerobic system available for and what is its fuel source?
|
hours and fatty acids/ glucose/ and protein
|
|
How are carbohydrates stored in the body?
|
as glycogen
|
|
What is glycogen a key fuel for and a secondary fuel for?
|
high intensity muscle contractions and secondary for aerobic exercise
|
|
What is bound to glycogen and what parts of the body is it stored in?
|
Water…muscles, liver and blood
|
|
Why are carbohydrate rich foods essential?
|
If you have a limited ability to store carbohydrates you must replenish glycogen after activity and carbohydrates provide important nutrients.
|
|
What are glycogen stores in the muscles of runners with high carb diets?
|
they are three times as high
|
|
What happens to endurance athletes when they don’t have enough carbs?
|
glycogen is depleted…more 02 is used to maintain speed…and fatigue
|
|
What happens to power athletes when they don’t have enough carbs?
|
power is reduced, muscle broken down for energy
|
|

|
it is broken down faster

|
antioxidants that help reduce disease risk
|
|

|
amino acids and a structural component of all body tissues
|
|
