physiology of training:

Question 1

How does endurance training affect performance

Answer 1

Changes in type and capillary content:
-shift in fast to slow fibers
-increase capillary supply
-intensity and duration dependent

Mitochondrial changes:
- increase up to 50-100% within 6 weeks
-amount of O2 consumed during sub maximal work is not affected by endurance training

Muscle fuel utilization:
- decrease utilization of plasma glucose
-increased fat metabolism
