Front (Question)

What are the two main categories of Hormones ?

Back (Answer)

• Amine & Polypeptide 2. Steroid derived

Front (Question)

Plasma concentration of hormones is determined by?

Back (Answer)

Rate of secretion Rate of metabolism or excretion Quantity of transport proteins Plasma volume

Front (Question)

Magnitude of hormone effect depends on ?

Back (Answer)

Concentration of hormone Number of receptors affinity Up or down regulation

Front (Question)

Two ways in which Growth Hormone affects energy fuel during exercise

Back (Answer)

• Decreases tissue glucose uptake 2. Increase Fatty acid mobilisation

Front (Question)

How does cortisol affect fuel during exercise

Back (Answer)

• stimulate FFA mobilisation from adipose tissue • enhance gluconeogenesis in the liver • decrease the rate of Glucose utilisation by cells

Front (Question)

Cortisol during low intensity exercise will? Increase or decrease

Back (Answer)

Decrease

Front (Question)

Cortisol during high intensity exercise will? Increase or decrease

Back (Answer)

Increase

Front (Question)

What is the function of Catecholamines during exercise in regards to BGL

Back (Answer)

• Muscle Glycogen mobilisation • liver glucose mobilisation • FFA mobilisation • interfere with glucose uptake • Inhibits pancreatic Beta cells • Stimulates pancreatic alpha cells

Front (Question)

What happens to plasma insulin during exercise

Back (Answer)

Concentration decreases

#10

Front (Question)

What happens to insulin following training

Back (Answer)

Decreased response

#11

Front (Question)

Essentially, during exercise Epinephrine, Ne, GH, Cortisol, Glucagon will all___________ and insulin will _________

Back (Answer)

Increase Decrease

#12

Front (Question)

What hormones are released from Adipose tissue ?

Back (Answer)

Leptin Adiponectin

#13

Front (Question)

What is the function of Leptin

Back (Answer)

• influences appetite • increase insulin sensitivity • fatty acid oxidation

#14

Front (Question)

What is the function of Adiponectin

Back (Answer)

Increase insulin sensitivity and fatty acid oxidation

#15

Front (Question)

How does leptin and adiponectin respond in Obesity

Back (Answer)

Increased leptin levels Decreased Adiponectin

#16

Front (Question)

How can skeletal muscle be justified as an endocrine Gland

Back (Answer)

It releases Myokines during contraction

#17

Front (Question)

List 3 ways hormones can affect enzymes within a cell

Back (Answer)

• stimulate enzyme production • increase or decrease effectiveness (Allosteric modulation) • increase total activity (Activates inactive enzyme forms)

#18

Front (Question)

List actions of Growth Hormone

Back (Answer)

• release IGF • amino acid uptake and synthesis • long bone and muscle growth • spares plasma glucose ( increases gluconeogenesis) • Fatty acid mobilisation • decreases tissue glucose uptake

#19

Front (Question)

Three functions of testosterone

Back (Answer)

• Promotes tissue building • Performance enhancement • Masculine characteristics

#20

Front (Question)

List the hormones implicated in regulation BGL

Back (Answer)

• insulin • Glucagon • GH • Cortisol • Catecholamines • somatostatin

#21

Front (Question)

How does somatostatin effect BGL

Back (Answer)

• inhibits Glucagon and thereby decreases BGL

#22

Front (Question)

With regards to intensity, when will NE and Epi be released?

Back (Answer)

NE - around 50% VO2 max. E - higher release as intensity increases (highest concentration seen at 100-110% of VO2 max)

#23

Front (Question)

What is the common intracellular mediator of Catecholamines

Back (Answer)

• Cyclic AMP

#24

Front (Question)

How does training effect Catecholamines?

Back (Answer)

• NE release is lower in trained individuals - NE and Epi output both decrease within weeks of training
