Cardiorespiratory Endurance

1
Cardiorespiratory Endurance

• Chapter 6

2
Basic Cardiorespiratory Physiology A Quick Survey

• Pulmonary, cardiovascular, muscular systems
• ATP
• Oxygen uptake (VO2)
• Aerobic anaerobic exercise

3
Benefits of Aerobic Training

• Higher maximal oxygen uptake (VO2max)
• Increased O-carrying capacity of blood
• Decrease in resting heart rate
• Lower HR _at_ a given workload
• Increased number/size of mitochondria

4
Benefits of Aerobic Training

• Increase in number of functional capillaries
• Ability to recover rapidly
• Lower BP blood lipids
• Increase in fat-burning enzymes

5
Physical Fitness Assessment

• Purposes
• Responders vs. nonresponders

6
Assessment of Cardiorespiratory Endurance

• Components of oxygen uptake
• Heart rate
• Stroke volume
• Amount of oxygen removed from blood

7
Tests to Estimate VO2max

• 1.5-Mile Run Test
• 1.0-Mile Walk Test
• Step Test
• Astrand-Rhyming Test
• 12-Minute Swim Test

8
Tests to Estimate VO2max

• Interpreting the results of your maximal oxygen
  uptake
• Predicting oxygen uptake caloric expenditure
  from walking jogging
