Simon Elvmarker and Azam Hamid

We all think of streamlining when swimming under water, and we know it makes a big difference to train for a good streamline. Now we have been wondering how much of a difference it actually makes - can we put numbers to this?

Enter Simon Elvmarker on his AIDA instructor course with us. Simon happens to have a background which allowed him to run the numbers on this and deliver a qualitative analysis of fluid dynamics in freediving.

As a bonus, he also looked at the fluid dynamics of shark skin and the (in-)famous swimming suits that carry that name. 

We were surprised by the results. - Read his paper attached below.

Oli Christen

Oli Christen, AIDA Instructor, is the  founder of the freediving school Freedive Flow in Bali, Indonesia and has been a valuable member of the AIDA Education work group.

During his AIDA Instructor Course with We Freedive Thailand,  Oli applied his background in psychology to his new career and gave a brilliant presentation on Action vs. State Orientation in Freediving, a topic that very likely all freedivers have experienced who have gone to a new depth.

Gary McGrath training in the pool

Our friend Gary McGrath went through his AIDA Instructor training with us and his final presentation was about 

Shallow Water Conditioning for Depth and Diaphragm Conditioning for Freedivers

It's a lovely read looking at preparation for the pressure and general big-hug-from-the-sea feeling we are exposed to at depth - and that preparation without having access to said depth. This preparation will make a big difference towards staying far away from sqeezes (ear, sinus, trachea or lung barotrauma) and enjoying your limited time at depth just that much more.

This one is for all of you pool freedivers in cold-water and landlocked exile with some excellent suggestions.

Clinton Laurence, psychologist and multiple black belt, came to us for his Freediving Instructor Course.

The intense exchange with an accomplished athlete - who not only has some very good insights into the human mind, but is also a generally great guy - was rewarding and fun at the same time and we are happy to have trained with Clinton.

As his Instructor Course presentation, Clinton gave an excellent talk on Mindfulness in Freediving.
