In competitive free-diving—also called competitive apnea—individuals attempt to reach extreme depths or distances underwater on a single breath without using breathing equipment. Some events allow the use of fins or weights, while others do not. Because a lack of oxygen can result in a loss of consciousness, free-diving requires intense training and supervision. What is the current record for timed underwater breath-holding as recognized by the International Association for Development of Apnea? Discuss
