~ Kayaking is a sport that relies heavily on aerobic power.
A strong aerobic base will allow a kayaker to work longer, at higher intensity,
thereby delaying fatigue and improving recovery time.

The level of aerobic power is determined by measuring the rate at which the body can
breathe in oxygen to the lungs, transfer oxygen from the lungs to the heart, deliver the
oxygen through the blood to the working muscles, extract the oxygen from the blood to
the muscles, and then use the oxygen in the muscles for energy production.

Once the intensity increases beyond the aerobic threshold the body uses anaerobic
methods to produce energy. This causes lactic acid to be produced. ~
