ADAPTATION TO AEROBIC AND ANAEROBIC TRAINING

1. 1. What is the best indicator of cardiorespiratory endurance ?

• Stroke volume

• Residual volume

• Heart rate

• VO2 max

2. 2. What happens to resting heart rate after aerobic training ?

• Increases dramatically

• Decreases (bradycardia)

• Remains unchanged

• Becomes irregular

3. 3. Which heart chamber shows the greatest adaptation to endurance training ?

• Right atrium

• Left atrium

• Left ventricle

• Right ventricle

4. 4. What causes the increases in blood volume after aerobic training ?

• Decreased plasma

• Increased plasma volume

• Loss of electrolytes

• Dehydration

5. 5. What happens to tidal volume during maximal exercise after aerobic training ?

• Decreases significantly

• Increases

• Disappears

• Remains constant

6. 6. What change is observed in submaximal heart rate after several months of training ?

• Increases by 30 - 50 bpm

• Decreases by 20 - 40 bpm

• Remains the same

• Becomes erratic

7. 7. How do muscle fibers adapt to aerobic training ?

• Type I fibers decreases

• Mitochondria dissapear

• Type I fibers increase in size and number

• Type IIx fibers take over to muscle work

8. 8. How does aerobic training affect lactate threshold ?

• Lowers it for faster fatigue

• Has no effect

• Causes more lactate accumulation

• Raises it to a higher % of VO2 max

9. 9. What change occurs in oxidative enzymes after training ?

• Increases in activity

• Complete inactivity

• Reduction in number

• Become anaerobic enzymes

10. 10. What happens to pulmonary diffusion at maximal intensity post training ?

• Becomes blocked

• Increases due to better lung perfusion

• Decreases

• Reverses gas exchange
