T2 L11: Energy during exercise Flashcards
1
Q
Which vascular receptors result in vasodilation?
A
Beta-2 adrenoreceptors
2
Q
What is the mechanism behind lactate accumilation?
A
When the oxygen supply is insufficient so lactate forms faster than it can be oxidised
3
Q
What can cause a decline in force generated by a muscle?
A
Pyruvate accumulation because it decreases muscle pH and glycolysis is inhibited by H+
4
Q
What are Catecholamines?
A
Molecules that help the body respond to stress
5
Q
What is meant by ‘hitting a wall’?
A
When exercise intensity drops because of lack of ATP. Fatty acid oxidation only generates 50% of maximum power output
6
Q
What are some symptoms of hypoglycaemia?
A
Dizziness, lack of cognitive function, lactis acidosis, confusion
