What is delayed onset muscle soreness (DOMS)?

• Immediate muscle pain during exercise

• Muscle pain or stiffness felt 24 to 72 hours after exercising

• Bone pain after exercise

• Joint pain during exercise

Which of the following increases during exercise to improve oxygen delivery?

• Tidal volume

• Bone density

• Muscle size

What is the result of increased stroke volume during exercise?

• Decreased cardiac output

• Increased cardiac output

• Decreased heart rate

• Decreased tidal volume

Which of the following is a long-term adaptation to regular exercise?

• Increased respiratory rate during exercise

• Increased size and strength of the heart

• DOMS

• Increased minute ventilation during exercise

What is cardiac hypertrophy?

• Decrease in heart size

• Increase in heart size and strength

• Decrease in muscle size

• Increase in bone density

Which adaptation leads to improved efficiency of gaseous exchange?

• Increased capillarisation of the lungs and muscles

• Increased bone density

• Increased muscle soreness

• Decreased tidal volume

What happens to resting heart rate after long-term regular exercise?

• It increases

• It decreases

• It stays the same

• It fluctuates randomly

Which muscles become stronger as a long-term adaptation to exercise?

• Only leg muscles
