Gear up 4 freediving with preparation and knowledge by L.A. Need

Freediving used competitively by holding breath to attain the greatest depths, distances and overall time is also referred to as freediving apnea. Due to the serious nature of freediving, adequate training, freediving manuals and proper gear and wetsuit is required for competitive and leisure freediving.

Withholding breath while underwater and descending to greater depths makes certain demands on the body. Understanding the demands placed on your body in response to high pressure and lack of air will help a diver achieve their goals safely. Here are a few physiological demands that must be achieved safely with each freediving adventure.
* Pulse rate will drop
* Blood vessels will shrink resulting in blood flowing from the limbs to the heart, main arteries and brain.
* Blood plasma will shift to the blood vessels of the lungs reducing the likelihood of lung damage.
With proper training the above physiological demands can be met without sacrificing safety when freediving.

Training for freediving requires training your muscles for anaerobic conditions and to increase your overall tolerance for CO2 buildup. An example of anaerobic training on land is referred to as the apnea walk. The apnea walk requires the trainee to take 2 to 3 slow preparatory breaths before holding their breath for 1 minute and walking as far as they can before taking their first breath. This teaches the trainee the distance they achieved as well as the necessity of prepping their body with slow deep breaths before the breath holding. For adequate instruction refer to freediving manuals.

CAUTION: If not trained properly, hyperventilation can initiate shallow and deep water blackout and ultimately result in drowning. Like any sport that involves risk, freediving must be learned and practiced consistently to achieve competency with aquatic sports.
