How to practice Apnea Tables
Have you ever wonder, can you hold your breath for longer?
James Nestor in his book Deep has an exciting story about the breathtaking competition that pushes the boundaries of human abilities. Only with a single breath, divers will submerge to depths of 300 feet, to grab a flag that hangs at the bottom of a piece of rope. At those depths the water pressure is bone-crushing. A typical trip down and back takes nearly four minutes. But these freedivers are able to train their bodies to do nearly the impossible.
Actually, freedivers are improving their breath-hold times for years with the apnea tables and other exercises.
Safety first!
The static Apnea tables are designed to be done in a safe environment. It’s forbidden to perform the tables near water without a person who is informed what are you doing.
Know your limits and train without feeling too uncomfortable. Consistency is more important than intensity. Better slow progress than no progress at all.
Don’t Hyperventilate!
Hyperventilation tricks your body into thinking you have more oxygen than you do by reducing the amount of CO2 in your bloodstream.
When you breathe, the oxygen coming in is converted into CO2. When you hold your breath, this CO2 starts to build up, and when this buildup begins to reach a critical level, you feel that overwhelming urge to take a breath and get some new oxygen into your system. When you hyperventilate, you reduce the amount of CO2 in your blood, but you don’t boost its oxygen. These lower levels of CO2 delay the activation of the body’s “need to breathe” reflex far past the point where it should have been triggered. In short, the reason you can hold your breath longer when you hyperventilate isn’t because of an increase in oxygen, but because of a decrease in CO2.
What it is:
Apnea table workouts aim to make our bodies adapt and get used to low levels of oxygen and high levels of carbon dioxide.
Before you start
You should measure your best time in the Tables Best Times section of the app. Upon a new best time your O2 and CO2 tables are going to be recreated for your new time.
You can hold your breath on inhaling or exhaling. There is no general rule which one is better.
If you are already experienced enough to practice in the water the inhale tables are considered to be safer. If you have less time in the day, exhale tables can save you some time. You can start with inhale tables for a month and switch to exhale tables for the next month, just to surprise the body and move away from the comfort zone.
CO2 Table
This table gives you less and less time to recover in between breath-holds. So the co2 in your blood and tissues slowly build up throughout the exercise. This slow increase develops your tolerance to the CO2. People who have a really strong, or early desire to breathe need to concentrate on CO2 tables.
Here’s an example of a CO2 static apnea table:
Let’s say your best hold time is 1min. and 30sec. The maximum hold should be no more than 50% of that time.
- Breathe 1:00 – Hold 0:45
- Breathe 0:52 – Hold 0:45
- Breathe 0:45 – Hold 0:45
- Breathe 0:38 – Hold 0:45
- Breathe 0:31 – Hold 0:45
- Breathe 0:24 – Hold 0:45
- Breathe 0:17 – Hold 0:45
- Breathe 0:10 – Hold 0:45
During your rest period, it’s important to breathe normally – don’t hyperventilate! Here you can use the Hold Prep breathing assist just to make sure that your breathing is consistent during the current exercise and different workouts.
O2 Table
While CO2 tables train your body to deal with high levels of CO2 in your system, O2 tables condition your lungs to store more oxygen, and your body to operate on lower levels of it. With O2 tables, your breath holds will get longer while your rest periods will stay the same.
Here’s an example of an O2 static apnea table:
Let’s say your best hold time is 1min. and 30sec. The maximum hold should be around 75-80% of that time.
- Breathe 1:00 – Hold 0:36
- Breathe 1:00 – Hold 0:40
- Breathe 1:00 – Hold 0:45
- Breathe 1:00 – Hold 0:49
- Breathe 1:00 – Hold 0:54
- Breathe 1:00 – Hold 0:58
- Breathe 1:00 – Hold 1:03
- Breathe 1:00 – Hold 1:07
Again during the rest period, just breathe normally! And again here you can use the Hold Prep breathing assist just to make sure that your breathing is consistent during the current exercise and different workouts.
Simple Training plan:
Measure your inhale best time. Start with 2 weeks of doing the CO2 Inhale tables. After that switch to 2 weeks of doing the O2 Inhale tables. After the first month, measure your exhale best time and switch to Exhale tables for the next month. Use the same 2 weeks schedule.
When you gain more experience you can make both tables on the same day separated by at least 6-8 hours. However, keep in mind that quality is more important than quantity.
When you already feel comfortable enough you can switch the CO2 table with Wonka / One Breath. Or create your custom tables.
What to expect:
The 3 stages of breath-hold
In the first stage, you’ll get an urge to take a breath because of the CO2 building up in your system, and if you resist it, your diaphragm will start having contractions. You can train yourself to go through these contractions.
In the second stage, your spleen releases up to 15% more fresh, oxygen-rich blood into your bloodstream. When this oxygen-rich blood hits your system, the body calms down and an experienced freediver will often feel a surge of energy. In this stage, you should learn to listen to your body and know your limits.
Because stage three is the loss of consciousness. Your brain uses about 20% of your body’s oxygen, and will just shut down when it senses there’s not enough in your bloodstream. If this happens underwater, the exit can be fatal.
Where and when to do it:
Find a place where you won’t be disturbed. Depending on your training plan you should spread your workouts in the time when your stomach is empty. You can still do the training on a full stomach, but you are going to feel more discomfort.
How to do it:
The breathing.
- Find somewhere comfortable to sit or lie down. If you can, close your eyes.
- No deeper or faster breathing than you would normally. Use the Hold Prep breathing assist if you feel difficult to stay consistent.
- Depending on the hold type (inhale or exhale):
- Inhale – Take a deep breath in around 75% of your full capacity, then exhale everything, then take a really deep breath… as deep as you can manage. Hold
- Exhale- Take a really deep breath… as deep as you can manage, then exhale everything, then take a deep breath in around 75% of your full capacity and finally exhale around 50 – 60% of your full capacity. Hold
- Relax. Every move or tension in the body is going to reflect on your performance.
The retention.
Stop the air escaping at the glottis or the back of the throat, not at the lips. Never release any air until you intend to breathe again. Relax your mind and body.
What to keep in mind:
A good physical condition is critical for your overall success. If you don’t feel well, take a day off. Drink a lot of water during the day. Eat healthily and don’t overeat. Don’t drink coffee or alcohol before your workout.
Consider including aerobic and anaerobic training in your physical training regime!
