Chapter 12_Adaptations to Anaerobic and Aerobic Training

In response to chronic endurance training, capillary density

• increases

• decreases

• fluctuates

• remains the same

Chronic endurance training results in what change to muscle fibers?

• type I fiber hyperplasia

• type II fiber hypertrophy

• type I fiber hypertrophy

• Type IIa fibers behave more like type IIx fibers.

VO₂ max=

• max heart rate × max (a-v) O₂ difference

• max stroke volume × max heart rate

• max HR × max SV × max (a-v) O₂ difference

• max stroke volume × max cardiac output

Which of the following is not a mechanism of increased stroke volume after endurance training?

• increased resting and submaximal heart rate

• increased plasma volume

• increased filling time

• increased LV wall thickness and chamber volume

Which chamber of the heart adapts most to chronic endurance training?

• right atrium

• left atrium

• right ventricle

• left ventricle

In response to aerobic training, muscle fiber mitochondria

• increase in size and number

• increase in number only

• decrease in number but increase in size

• increase in number but decrease in size
