Y12 Chronic responses to exercise test

A chronic adaptation is:

• The body's short term responses to training
• The body's long term responses to training
• An enlargement of the heart
• JImprovements in motor unit recruitment and performance

What section of the heart increases?

• Right Ventricle
• Left Ventricle
• Right Atrium
• Aorta

An increase in aerobic training will also see:

• An increased a-VO2 difference
• An decreased a-VO2 difference

What happens to an individuals blood pressure following an extended training period?

• Increase
• Decrease
• No change

How does the increased capillary density of skeletal muscles benefit the individual?

• More blood flow around working muscles, which leads to an increase in oxygen uptake
• More oxygen extracted from alveoli
• No change in trained athlete
• Decrease in oxygen uptake and blood flow to working muscles

At sub-max, HR rate ___________. Which results in:

• Increases; the heart becoming more efficient
• Decreases; the lungs becoming more efficient
• Increases; the lungs becoming more efficient
• Decreases; the heart becoming more efficient

An increase in oxygen transportation occurs due to an increase in: 

• Heart Size
• Lung Capacity
• Glycogen Stores
• Mitochondria Volume

As a result of aerobic training, red blood cell count will:

• Increase
• Decrease
• Remain the same

Aerobic training changes the mitochondria by ...

• Increasing Size
• Increasing Number
• Increasing Surface Area
• All of the above

At maximal intensities, Stroke Volume increases and Heart Rate remains the same. This results in:

• an increase in Ventilation
• an increase in Blood Pressure
• an increase in Cardiac Output
• an decrease in Blood Flow to working muscles
