Module 2 - Chapter 5: Macronutrient Metabolism In Exercise & Training Flashcards
Which one is the one that drives most of it when a person is doing High-Intensity endurance exercise?
A. Fats
B. Glucose & Glycogen
C. Protein
B. Glucose & Glycogen
What are the source of energy for ATP systhesis?
Carbohydrates (liver & muscle glycogen)
Fat (Triacylglycerol within Adipose tissue & active muscle)
Protein (amino acids within the skeletal muscle donate those carbon skeletons)
What is Gluconeogenesis?
It refers to the combination pathways to make Glucose with lactate, glycerol and certain amino acids.
What are the 3 hormones use during exercise?
Glucagon
Epinephrine
Cortisol
Which nutrient are able to generates 6% of energy per unit of oxygen consumed?
A. Fat
B. Carbohydrates
C. Protein
B. Carbohydrates
Generally what nutrient do we use as energy for lower intensity activity like walking, resting?
Fat
What is the minimum Carbohydrate requirements for a Heavy exercise / duration 90 mins endurance training?
A. 6 - 10g/kg
B. 3 - 5g/kg
C. 1 - 2g/kg
A. 6 - 10g/kg
Low carbs diet will affect the performance, why?
- Can’t have much glycogen store to use will affect performance
- Affect both aerobic and anaerobic exercise capacity
- Decrease exercise intensity
Which Macronutrients is important to have stored for prolonged exercise?
A. Fat
B. Carbs
C. Protein
A. Fat
What is going to affect when diet too low in fat?
Decrease testosterone levels
Affect recovery
Muscle protein synthesis
Where does the fatty acids go after released out from fat cells?
It delivered to muscle as free fat cells bound to plasma albumin
Which 4 endocrine that we use to regulate the fat and help to activate the lipase to open up the fat cells and mobilizes free fatty acids?
Epinephrine,
Norepinephrine,
Glucagon
Growth hormone
What is lipase’s responsibility after being activated?
Helps to open up fat cells, lipid cell and mobilize free fatty acid from Adipose tissue.
What does Hormones do in our body?
Influence the availability of substrates Mobilization from body tissue stores Uptake at tissue site of utilization Uptake within tissue itself Trafficking among storage, oxidation & recycling
What does BCAA do in our body and what are the components?
Helps to oxidize within the skeletal muscle rather than the liver.
Leucine
Isoleucine
Valine
