Freediving encompasses several disciplines, each with its own characteristics and requirements:
- Static freediving: this involves holding your breath for as long as possible, remaining motionless on the surface of the water. The competitor's static apnea time is measured in seconds or minutes.
- Dynamic freediving with fins: here, freedivers must swim a predetermined distance using fins while holding their breath.
- Dynamic freediving without fins: unlike dynamic freediving with fins, this training is performed without the use of fins. Freedivers must swim using only the strength of their arms and legs.
- Constant weight diving: in this discipline, freedivers descend and ascend using vertical lines. They can use weights to help them descend and ascend more easily.
