Lecture 9 - Recovery

Question 1

What is EPOC

Answer 1

EPOC is the total oxygen consumed in recovery - the total oxygen theoretically consumed at rest during the recovery period

Question 2

What is the oxygen deficit

Answer 2

Difference between the oxygen consumed during exercise and that which would have been consumed if steady state VO2 was achieved instantly at exercise onset

Question 3

Why does EPOC matter

Answer 3

Monitors performance in intermittent sports, allows for training programme designs, optimises recovery

Question 4

What are the 7 contributory factors to EPOC

Answer 4

ATP- PCR resynthesis 
Lactate oxidation 
Electrolyte restoration 
Shift in substrate utilisation 
Thermogenics 
TG and FFA cycling 
Increased HR and ventilation

Question 5

What type of response is PCr resynthesis and state the equation

Answer 5

Biphasic response: initial fast phase and a slower secondary slower phase

Question 6

What are the benefits and disadvantages of creatine supplementation

Answer 6

Increased strength, creatine storage, free fat mass and faster ATP regeneration.

Increased time diminishes effects not the same for everyone

Question 7

What are the 3 none CHO precursors that form glucose

What is the cori cycle

Answer 7

Lactate purists and glycerol

Cori cycle is where lactate is converted to glucose in the liver and transported to the muscles

Question 8

Describe reesterfication

Answer 8

Glycerol + 3 FFA from adipose tissue, forms triacylglycerol, contributes to evergy needed during EPOC

Question 9

What is DOMS and the 7 contributory factors

Answer 9

Delayed onset muscle soreness
24-72 hours

Causes

Minute tears 
Fluid retention 
Muscle spasms 
Overstretching or tearing of connective tissue 
Acute inflammation 
Altered calcium regulation 
All of above
