A.2.3.2VO2 Max

What is VO2 max primarily a measure of?

• Muscle strength and power

• Maximum oxygen consumption rate

• Lung capacity only

• Heart rate at rest

How is VO2 max typically expressed when considering activities like running?

• Watts per minute

• Liters per minute

• Milliliters per kilogram per minute

• Calories per hour

What is the typical VO2 max range for moderately trained biological males?

• 35-40 ml/kg/min

• 45-55 ml/kg/min

• 60-65 ml/kg/min

• 70-75 ml/kg/min

At what age do both biological males and females typically reach their peak VO2 max?

• 18-25 years

• 25-30 years

• 30-35 years

• 35-40 years

Which factor accounts for approximately 69% of the differences in VO2 max scores among individuals?

• Age

• Gender

• Body mass

• Training status

Which type of muscle fiber has the highest oxygen consumption?

• Type IIb fibers

• Fast-twitch fibers

• Type I (slow oxidative) fibers

• Mixed fibers

Why do biological females typically have lower VO2 max values than biological males?

• Lower motivation during testing

• Smaller lung capacity and blood volume

• Slower metabolic rate only

• Different muscle fiber types

Which exercise mode typically produces the highest VO2 max values?

• Cycling

• Swimming

• Treadmill running

• Arm ergometry

What adaptation occurs in trained athletes that contributes to higher VO2 max?

• Decreased muscle mass

• Lower hemoglobin concentration

• Increased cardiac output

• Reduced capillary density

What happens to VO2 max at higher altitudes?

• It increases due to adaptation

• It remains constant

• It decreases due to lower oxygen availability

• It fluctuates randomly
