Week 1 Flashcards
What are the 5 aspects of exercise physiology
Physiology, homeostasis/steady-state, acute exercise, chronic exercise, exercise testing
Carbs role in the body
Energy source during intense exercise
Protein sparer
Fuel for the CNS
Metabolic primer
CHO intake (carbs)
Sedentary 70kg person- 300g or 40-50% of total cals
Physical active- 400-600g or 60%
Athlete- 70% or 8-10kg of body mass
What results from a low CHO diet
Rapidly compromises glycogen reserves for vigorous physical activity and intense training
Where and what does glycogen store
Carbs in the muscle and liver
Carbs in kcals stored as carbs
2000 kcals
Muscle stores about ____ of glycogen
400g
Liver stores___ glycogen
100g
What’s the upper limit of glycogen storage
15 g/kg BW
What does glycogen stores do during exercise
Provide major carbs supply for active muscles
GI
Serves relative qualitative indicator to raise blood glucose levels
Lipid’s role
-Energy source and reserve
-Protect vital organs
-Thermal insulation
-Vitamin carrier and hunger suppressor
Lipid intake
20-35% of daily kcal
More or equal of total lipids should be unsaturated fatty acids
Recommended % of saturated and trans fats
Saturated- <7%
Trans- <1%
Factors influencing fat consumption
Personal taste
Money spent on food
Geographical influences
Availability of lipid-rich foods
