Cardiorespiratory Endurance Quiz

Which of the following is a reason why cardiorespiratory endurance decreases with age?

• Increased elasticity of lungs

• Increased haemoglobin levels

• Decreased muscle mass and mitochondria

• Increased oxygen uptake

Why do males generally have higher cardiorespiratory endurance compared to females?

• Smaller size of lungs

• Lower haemoglobin levels

• Greater muscle mass and more mitochondria

• Fewer slow-twitch muscle fibers

What effect does a greater percentage of slow-twitch muscle fibers have on cardiorespiratory endurance?

• Decreases ability to work aerobically

• Increases ability to work aerobically

• Reduces number of mitochondria

• Decreases oxygen transport

Which factor directly increases oxygen transport in the body?

• Decreased haemoglobin

• Increased haemoglobin

• Decreased muscle mass

• Decreased elasticity of lungs

A student is planning a training program to improve their cardiorespiratory endurance. Based on the summary, which muscle fiber type should they aim to increase, and why? (DoK Level 3)

• Fast-twitch fibers, because they have more mitochondria

• Slow-twitch fibers, because they increase the ability to work aerobically

• Fast-twitch fibers, because they increase oxygen uptake

• Slow-twitch fibers, because they decrease oxygen transport

What does flexibility reflect in the human body?

• The ability of muscles and connective tissues to stretch

• The strength of bones

• The speed of muscle contraction

• The endurance of the heart

Which of the following best describes flexibility according to the key definition?

• The ability to lift heavy weights

• The range of motion of a joint

• The speed of running

• The endurance of muscles

Which statement is true about flexibility?

• Good flexibility in one joint means you have good flexibility in all joints

• Flexibility is the same for every person

• Flexibility is joint-specific

• Flexibility only applies to athletes

Which of the following sports is NOT typically associated with flexibility?

• Gymnastics

• Hurdles

• Chess

• Martial arts

A student wants to improve their flexibility for rock climbing. Which concept should they focus on based on the information provided?

• Increasing the range of motion in specific joints used in climbing

• Running faster

• Lifting heavier weights

• Improving memory skills
