There is a breath technique that is often confused with skip breathing. This is when divers wear very little weight but rather use their lungs to control their buoyancy. At full capacity, your lungs carry six to eight pounds of floatation, so by adjusting the amount of air you breathe, you can regulate you depth. Breathe in more deeply and you’ll increase your buoyancy; breathe in less, and you’ll submerge. The major technique for conserving air underwater is to breathe in as relaxed a mode as you can. Remember that breathing air underwater is different than breathing air on the surface. As you dive deeper, the density of the gas increases so you’ll be working harder to breathe unless you’re employing long, slow breaths . Says David Taylor, PADI Dive Master and Nitrox and Technical Diver, “That’s something people don’t usually catch on to until 40 or 50 dives.”
Tom Mount, president of the International Association of Nitrox and Technical Divers, recommends doing a t-ai chi breath exercise: breathing in for six to eight seconds, a natural two or three seconds pause, then exhaling for six to eight seconds. “While you’re doing it,” Mount says, “concentrate on breathing with your diaphragm. This is the way we were born breathing. But we lose it through bad habits and our cultural upbringing. You go to school and they say, ‘Chest out, shoulders up, stomach in,’ that destroys diaphragmatic breathing.” Mount suggests this exercise: Lie on your back, putting one hand on your chest and the other on your stomach. As you breathe, make sure your stomach rises and not your chest. “Once you learn to breathe with your diaphragm,” says Mount, “practice it all the time until it becomes a reflex.”
Diaphragmatic breathing is the only way to get air into the lower third of your lungs, which is where two-thirds of the blood supply is. This breath technique will increase the efficiency of your lungs. It will enhance your ability to metabolize oxygen. Breathe with your diaphragm – and you’ll improve your performance and endurance in any sport.
