Physiology Of The Endurance Athlete

Question 1

Describe how an increase in muscle capilliarisation affects a-vO2 difference

Answer 1

Increased capillary density in muscle

Increase in mean transit time

Maintenance of a-vO2 diff. Even at high intensity

Question 2

How does training in a muscle glycogen depleted state improve endurance performance

Answer 2

Results in enhanced mobilisation of fatty acids for fuel

Results in enhanced use of fatty acids for fuel

Spare glycogen = deferred accumulation of waste products associated with glycolysis
