Constant Weight Apnea is a type of freediving discipline where divers hold their breath while descending and ascending in the water without changing their weight. The goal is to reach a specific depth and return to the surface while maintaining a constant weight, typically using a weighted belt or similar equipment. In this discipline, divers must manage their buoyancy and breath-holding ability effectively. Constant Weight Apnea is often practiced in competitive settings, where athletes aim to achieve greater depths while ensuring safety and proper technique throughout the dive.
