Questions from this subtopic

Each one with the model answer underneath.

1
What happens to lactic acid after exercise?
Model answer
Most lactic acid is oxidised to carbon dioxide and water. Some is converted back to glycogen and glucose.
2
What is the Cori cycle?
Model answer
The Cori cycle is the process in which lactate is carried to the liver and converted back to glucose. The glucose can return to the muscles.
3
How does an active cool-down speed the removal of lactic acid?
Model answer
Light exercise keeps blood flowing through the muscles. Lactic acid is carried away and oxidised more quickly.
4
How do ice baths aid recovery?
Model answer
Cold water narrows the blood vessels and reduces swelling. Fresh blood then flushes the muscles as the body rewarms.
5
How does compression clothing aid recovery?
Model answer
Compression garments squeeze the limbs and improve venous return. Waste products are removed more quickly.
6
How does massage aid recovery?
Model answer
Massage increases blood flow to the muscles and relieves tension. It may reduce soreness.
