Underwater blackout vs surface blackout in competition. What’s the difference?
Had my first pool competition and it was a really nice experience.
Most people were very friendly and relaxed, and it was a great opportunity to learn from athletes who have been practicing freediving for years and to observe how they prepare themselves before performing.
Blackouts were not pleasant to witness, even in a safe environment, but I understand they are part of a sport where people push themselves to their limits.
I noticed a distinction between an underwater blackout and a surface blackout. In the first case, the athlete was forbidden from competing the following day, while in the case of a surface blackout, the athlete was only disqualified from that specific discipline.
Technically and medically, what are the differences between the different types of blackout, and what is the reasoning behind those rules?
From a medical perspective, a blackout is still a blackout. The only additional concern I can think of with an underwater blackout would be water aspiration into the lungs, although that could also depend on the safety response and how quickly the athlete was recovered, rather than solely on the athlete’s condition itself.
