I. Introduction

● What is freediving

Freediving is a form of underwater diving where the diver holds their breath and does not use any breathing apparatus, such as scuba tanks. The diver relies on their own lung capacity and physical fitness to stay underwater for as long as possible. Freediving encompasses a wide range of activities and disciplines, including recreational diving, competitive diving, and spearfishing.

Recreational freediving is done for the purpose of leisure, relaxation, and enjoying the underwater environment. Competitive freediving is a sport that involves divers competing in various disciplines such as depth diving, time, and distance swimming. Spearfishing is the practice of hunting fish or other aquatic animals using a spear or a similar tool.

Freediving is a challenging sport that requires a high level of physical fitness and mental discipline. Divers must be able to hold their breath for extended periods of time, have good control over their breathing and heart rate, and possess the ability to equalize the pressure in their ears as they descend. It is essential that divers take the proper safety precautions, such as having a buddy and using a dive watch or computer to monitor the time and depth of their dives.

Freediving has a rich history, dating back to ancient civilizations, such as the Greek and Roman empires, where spearfishermen and pearl divers used breath-hold techniques to harvest seafood. In recent years, freediving has grown in popularity, with many people discovering the sport as a way to connect with nature, experience the thrill of adventure, and push their physical and mental limits.

● Explanation of the different disciplines of freediving

Freediving is a diverse sport that encompasses a variety of disciplines, each with its unique set of rules, techniques, and equipment. Some of the most popular disciplines in freediving are:

• Constant Weight (CWT):

In this discipline, the diver descends and ascends using only their own strength, without pulling on the rope or using propulsion devices. The diver carries a weight that allows them to achieve neutral buoyancy at the surface, but not at depth. This discipline is considered one of the purest forms of freediving, as the diver is only using their own strength to reach depth and return to the surface.

• Free Immersion (FIM):

Similar to Constant Weight, but instead of using fins, the diver pulls themselves down and up the line using only their hands.

• Variable Weight (VWT):

In this discipline, the diver descends on a weighted sled and ascends using a rope. This allows the diver to reach greater depths than they would be able to using only their own strength.

• No Limit (NL):

In this discipline, the diver descends on a weighted sled and ascends using a buoyancy device such as a lift bag. There are no limits to the amount of weight that can be used, which allows divers to reach extremely deep depths.

• Static Apnea (STA):

This discipline involves holding one’s breath for as long as possible while floating on the surface of the water.

• Dynamic Apnea (DYN):

This discipline involves swimming horizontally under water for as far as possible on a single breath.

• Depth disciplines, Constant Weight Without Fins (CNF) and Free Immersion Without Fins (FIM) are also part of the freediving disciplines.

Each discipline requires a different set of skills and techniques, and divers must train specifically for each one. Understanding the different disciplines of freediving allows divers to choose the discipline that best suits their abilities and interests.
