Freediving competitions are events where participants dive underwater without the use of breathing apparatus, relying solely on their ability to hold their breath. Competitors aim to reach the greatest depth or distance while adhering to specific rules and safety protocols. Various disciplines exist, including Constant Weight, Free Immersion, and Static Apnea, each testing different skills and techniques. These competitions are governed by organizations like AIDA International and CMAS, which ensure fair play and safety standards. Divers are often supported by safety teams and use surface markers to track their progress. The sport emphasizes both physical and mental training, making it a unique challenge for athletes.
