09c. Chronic Ads - Aerobic Muscular Flashcards
What type of muscle fibre does not fatigue easily and has increased blood supply
Slow twitch fibres
Which energy system is associated with having a high LIP
aerobic
What are triglycerides?
fats stored in muscle
What is an advantage of using triglycerides as a fuel?
increased ATP resynthesised, increased yield
What is an disadvantage of using triglycerides as a fuel?
increased need for oxygen to break it down, decreased rate
What is an advantage of using glycogen as a fuel?
increased rate of ATP resynthesis
What is an disadvantage of using glycogen as a fuel?
limited stores, decreased yield
What is LIP?
the last point of balance where LA accumulation is equal to removal
What is the difference between the amount of oxygen in the arteries and the veins. It indirectly measures how much oxygen the muscles use.
AVO2 Difference
List 3 chronic aerobic muscular adaptations
Increased size and number of mitochondria, oxidative enzymes, triglyceride stores,
Outline how increased mitochondria size and number directly increases performance.
Oxidises glycogen and triglycerides faster to produce more aerobic energy
Outline how increased oxidative enzymes directly increases performance.
Produce aerobic energy faster by speeding up the breakdown (oxidise) of carbohydrates and fats.
Outline how increased oxidative enzymes and triglyceride stores together directly increases performance.
They breakdown triglycerides faster therefore increased ability to glycogen spare
What does myoglobin do
transport oxygen into the muscle
What does mitochondria do
produce aerobic energy
