A very short introduction to the freediving science

We are no scientists, but we are freedivers, and we want to understand as much as we can about the freediving science; and of course we are happy to share it with you!

The human body is an amazing and high tech piece of equipment and only in the most recent years we found out that we can freedive, and why.
In the late 16th century, chemist Robert Boyle predicted that diving beneath the oceans surface to around 30 meters was impossible due to the pressure created by the water crushing the human lung. According to “Boyles Law”, when the pressure increases on the outside of the lung, as it does when we dive down deep in the ocean, the volume of the lungs and the oxygen inside them must decrease by the corresponding amount by squeezing and compressing.

FAQ#4: Which Freediving Disciplines are there? Part 2

On the first part of this article we focused on the depth freediving disciplines, while here we will illustrate the pool disciplines. These are three: Static, Dynamic with Fins and Dynamic without Fins. Sometimes competitions are made in lakes instead of pool, if the conditions allow.

FAQ#4: Which Freediving Disciplines are there?

By Benajmin Boehme

This is article is directed to beginners or non-freedivers as an overview of the different freediving disciplines. We will go through each one of them and explain their benefits and difficulties.
In freediving there are six competition disciplines and two non-competition disciplines which sums up to a total of eight. This at least are the recognized AIDA disciplines. There are endless other disciplines like dynamic under ice where the freediver tries to cover the longest distance while diving under ice. Submerging in one hole and coming back out at another one. People keep being inventive and create more and more disciplines like tandem no limit diving etc.
