Freediving is as much about mental focus and physiological adaptation as it is about exploring the underwater world. Whether you're new to the sport or a seasoned diver, breath-hold training is a critical component of improving performance. Two cornerstone methods for breath-hold development are CO2 tables and O2 tables. These exercises not only enhance your breath-holding capacity but also fine-tune your body's response to the challenges of freediving. Here's a closer look at how these tables work and their benefits for divers.
What are CO2 and O2 tables?
CO2 and O2 tables are structured breath-holding exercises designed to develop specific adaptations in the body:
- CO2 tables: Focus on building tolerance to elevated carbon dioxide (CO2) levels. They consist of breath-holding intervals with progressively shorter recovery times, simulating the conditions of breath-hold dives where CO2 levels rise.
- O2 tables: Aim to help the body adapt to low oxygen (O2) levels. They feature constant recovery times but progressively longer breath-hold durations, training the body to function efficiently under oxygen-deprived conditions.
These exercises are dry training methods, which means they are practiced on land, making them a safe and convenient way to improve your skills.
The benefits of CO2 and O2 tables
1. Improved CO2 tolerance: The sensation of needing to breathe during a dive is primarily triggered by rising CO2 levels. CO2 tables train your body to better handle this buildup, delaying the urge to breathe. Over time, this allows divers to remain calm and focused during longer dives.
2. Enhanced oxygen efficiency: O2 tables train your body to conserve oxygen more effectively by increasing the efficiency of oxygen usage in vital organs and tissues. This adaptation is essential for deep dives and extended bottom times.
3. Increased mental resilience: Both types of tables challenge you to stay calm under stress. By simulating the discomfort of breath-holding in a controlled environment, these exercises build mental toughness that translates into more relaxed and confident diving experiences.
4. Customizable to your needs: CO2 and O2 tables are highly adaptable. Whether you're a beginner working on holding your breath for a minute or an advanced freediver training for a five-minute static apnea, these exercises can be tailored to match your personal bests and training goals.
5. More accessible and safer: Unlike in-water training, CO2 and O2 tables can be practiced safely at home, reducing the risks associated with blackout. This makes them accessible for regular practice, even for those without access to a pool or open water.
