0
Q
Catecholamines during exercise:
A
Increase linearly
Favour FFA mobilisation and maintenance of plasma glucose
1
Q
Three major classes of hormones:
A
Steroid
Protein and peptide
Tyrosine derivatives
2
Q
FFA mobilisation decreases during heavy exercise
A
In spite of persisting hormonal stimulation
3
Q
Cortisol:
A
Stimulates FFA mobilisation
Mobilises amino acids for gluconeogenesis
The Dawn Phenomenon
4
Q
Plasma cortisol during exercise at: low intensity and high
A
Low= decreases High= increases
5
Q
Insulin and exercise:
A
Decreases
Prevents rapid uptake of plasma glucose
Favours mobilisation of FFA
6
