Watching the women's 800, noticed the lead swimmers were only kicking for balance. The commentator observed this as well, and explained that your leg muscles are your largest muscles in your body, and use the most oxygen, yet only contribute 10-20% of speed/power to your freestyle -- hence, an inefficient use of oxygen in a distance event. They really only kick in the last 50M for the end.
Given this information, and the fact we tend to swim even longer distances, why would we kick in triathlon swimming?
