Dolphin diving has several benefits for triathletes. Knowing how to properly dolphin dive can put you far ahead of other swimmers who don't know how to use this technique. It allows you to build up a tremendous amount of momentum before you start swimming. In addition, when swimming against strong waves, dolphining will help ensure you aren't taken back to the shore by the current [source: NYC Swim].
You can even use dolphin diving to return to the shore when you finish swimming as well. When coming back, dolphin dive a few times as you approach the shore and ride the current in. This will help you transition from the swimming stage to the next phase of the triathlon.
Keep in mind that doing the dolphin dive has some drawbacks as well. Some swimmers argue that it's just as fast to walk or run into the water and start swimming right away. Also, if you're swimming in a big group of triathletes, you may not have enough room to perform the dolphin dive. Some triathlons even ban the practice of dolphining.
One warning: If you decide to do the dolphin dive at your next triathlon, remember to keep the diving shallow. If you dive too deep, you could seriously injure yourself.
