A swimmer is training for a 5-kilometre swim.

Which set of physiological adaptations is likely to occur?

  1. Decreased resting heart rate, increased stroke volume, decreased oxygen uptake
  2. Decreased resting heart rate, decreased stroke volume, decreased oxygen uptake
  3. Increased resting heart rate, increased haemoglobin levels, increased oxygen uptake
  4. Decreased resting heart rate, increased haemoglobin levels, increased oxygen uptake

D

Show Worked Solution
  • D is correct: Aerobic endurance training can decrease resting heart rate and increase haemoglobin levels and oxygen uptake.

Other options:

  • A is incorrect: Aerobic training increases rather than decreases the body’s capacity for oxygen uptake.
  • B is incorrect: Aerobic training increases stroke volume and oxygen uptake rather than decreasing them.
  • C is incorrect: Aerobic training generally decreases rather than increases resting heart rate.
