Exercise Physiology + Demands of Endurance + Metabolism

Question 1

When do exercise and nutrition link?

Answer 1

Body composition (train adaptation, recovery, performance)

Carbohydrate, fat, protein and amino acid metabolism

Macronutrient inflammation and immune system function

Gastrointestinal function, water and electrolyte balance

Question 2

What four things effect an individuals V02 max?

Answer 2

Cardiac output

O2 difference

Question 3

What effects an individual‘s lactate threshold?

Answer 3

Oxidative capacity of muscle quantity of muscle mass

Question 4

What affects an individual’s economy?

Answer 4

Type 1 fibre mechanics

Question 5

Glycogen sparring (Increases/Decreases)

Answer 5

Increased Lypolysis and mobilisation of FFA’s

Increase in catecholamines (norepinephrine, plopanine epinephrine)

Increased time to exhaustion

Decreased RER are not consistent

Question 6

Glycogen sparring is when

Answer 6

Adenosine binds receptors to CNS to inhibit neuromuscular release (Antagonist)

5.6% decrease in RER with caffeine

Improved rapid visual processing

Question 7

Glycogen sparring w/ CAF (Side effects)

Answer 7

Anxiety, jitters, Gl discomfort, insomnia

Dose of CAF < 9 mg/kg/bw aren’t dangerous

> 9 mg/kg/bw of CAF can cause muscular trauma, muscle impairment and decreased coordination
