Week 02 Flashcards
How do you determine the CHO?
By the number of CHO units
glucose has ___ units
6
monosaccharides include…(3)
glucose, fructose and galactose
Disaccharides include…(3)
sucrose, lactose and maltose
polysaccharides include…(2)
starch, glycogen
3-5 hours before competition you should have __________ g of CHO
140 to 330
30-60 mins before competition you should have …..?
small amounts of CHO (with high GI)
Immediate recovery (0-4 hr):
1.0-1.2 g/kg/hr
Daily recovery from moderate duration/low intensity training:
5-7 g/kg/day
Daily recovery from moderate to heavy endurance training:
7-10 g/kg/day
Daily recovery from extreme exercise programmes (4-6 hours per day):
10-13 g/kg/day
What is the optimal fuel source during high intensity exercise
Muscle glycogen
Gluconeogenesis is…?
glucose from fats, protein & other precursors (aside from glucose)
Glycogenolysis is…?
Breakdown of glycogen
Hepatic CHO metabolism is governed by (3):
- insulin (stimulates glycogen synthesis)
- Glucagon (stimulates glycogenolysis & gluconeogenesis)
- Catecholamines (stimulates glycogenolysis & gluconeogenesis)
Effects of exercise on insulin level…?
insulin decreases
Effects of exercise on glucagon level…?
glucagon increases
Effects of exercise on catecholamine level…?
catecholamines increase
From the change in these hormone levels with exercise, what happens to glycogen synthesis, glycogenolysis and gluconeogenesis with exercise?
- glycogen synthesis decrease
- glycogenolysis increases
- gluconeogenesis increases
Hepatic glucose output at rest: ____% from glycogenolysis and ___% from gluconeogenesis
60% from glycogenolysis
40% from gluconeogenesis
Hepatic glucose output with exercise: ____% from glycogenolysis and ___% from gluconeogenesis
90% from glycogenolysis
10% from gluconeogenesis
Hepatic glucose output increases/decreases with exercise?
increases
