Apnea competitions are events where participants test their ability to hold their breath underwater. These competitions focus on different disciplines, such as static apnea, where competitors remain still while holding their breath, and dynamic apnea, which involves swimming a distance underwater without breathing. Participants are judged based on their performance, and safety measures are in place to protect them during the events. Freediving is a popular sport that encompasses these competitions, attracting athletes from around the world who seek to push their limits in breath-holding and underwater endurance.
