Skeletal muscle blood flow in exercise

Give 5 methods of measuring skeletal muscle blood flow. Briefly explain what each of them are.

At the start of measuring skeletal blood flow we recorded lower values. What kind of values were recorded at this time?

What kind of values would we expect to see when using micro-dialysis as a method of measuring skeletal blood flow? Give some problems with this method of measurement.

Give some potential reasons for the sudden increase in blood flow at the onset of exercise.

What is sympatholysis?

Describe the process of functional sympatholysis.

Explain why we need a balance of vasoconstriction and vasodilation.

Explain what happens to blood flow during a isometric contraction. How does this effect time until fatigue?

Out of isometric contraction and intermittent contraction which allows us to sustain the contraction longest before fatigue. Explain why this is a case.

Describe what can happen when we contract our muscles and also try to vasodilate the vessels.

Describe the differences in blood perfusion of different muscle types.

What does tortuous mean?

We match capillary density to ______ content of the cell.

If we increase blood flow we _____ transit time. The higher the transit time the ____ gas exchange can take place

Explain what is meant by capillary recruitment. Describe the slight controversy with this concept.

Give some determinants of oxygen delivery in exercise.
