Vitomir Maričić, a Croatian freediver, broke the record for the longest voluntary breath-hold underwater, achieving 29 minutes and three seconds. This record surpasses the previous one by almost five minutes. Prior to the attempt, he breathed pure oxygen for 10 minutes, significantly boosting his blood oxygen levels. This preparation method, denitrogenation, allowed Maričić to enhance his breath-holding capacity, making it comparable to marine mammals. His performance occurred in a three-metre pool with judges and spectators on June 14.
Croatian freediver Vitomir Maričić set a Guinness World Record by holding his breath underwater for 29 minutes and three seconds, surpassing the previous record by almost five minutes.
By breathing pure oxygen for 10 minutes prior to the record attempt, Mr Maričić increased his blood oxygen levels to five times the normal limit, a method known as denitrogenation.
The technique allows for increased oxygen absorption in the lungs and blood, effectively expanding a person's 'safe apnea time', which is crucial in medical scenarios.
Mr Maričić’s achievement puts him on par with marine mammals, as he held his breath for twice the record length of a bottlenose dolphin's longest dive.
