🤿 Freediving Training Guide

Freediving Physiology Basics

Freediving — diving while holding the breath. The human body has an innate "mammalian dive reflex": upon entering water, the heart rate slows by 20–50%, blood is redirected to the brain and heart.

Breathing Techniques and Training

Extending breath-hold time depends on two factors: CO2 tolerance (how long you can ignore the urge to breathe) and O2 efficiency (how efficiently you use oxygen).

Breathing Exercise (CO2 Tolerance):

• CO2 Tables: 8 series of breath-holds with progressively shorter rest intervals.
• E.g.: Hold 1:30 → rest 2:00 → hold 1:30 → rest 1:45 → hold 1:30 → rest 1:30... until 0:15 rest.
• O2 Tables: Increasing hold times with constant rest.
• E.g.: Hold 1:00 → rest 2:00 → hold 1:15 → rest 2:00 → 1:30... until 3:00.

Preparatory Breathing:

• Diaphragmatic breathing: Deep abdominal breathing, not chest breathing.
• "Round" Breathing: Inhale 4 sec → hold 4 sec → exhale 8 sec.
• Final Inhale: Before diving — a full inhale, but not "forced". Too much air creates pressure.

Equalization

The biggest obstacle to deeper diving is not lack of oxygen, but the inability to equalize pressure in the ears. The Frenzel maneuver is the most effective method.

Pressure Equalization Methods:

• Valsalva: Pinch the nose and blow — suitable for shallow diving, does not work deeper than 10 m.
• Frenzel: Pinch the nose, use the tongue to push air into the Eustachian tubes — effective up to 30–40 m.
• Mouthfill: Air is stored in the mouth, used for deeper diving — an advanced technique.

Safety Protocols — Absolutely Essential

In freediving, safety is everything. Never, never, NEVER dive alone.

Golden Rules:

• 1. One Dives, One Safeguards: The safety diver always watches the diver.
• 2. Meeting at Depth: The safety diver meets the diver at half their maximum depth.
• 3. No Hyperventilation: Calm, normal breathing before diving.
• 4. After the Dive — Recovery Breathing: 3 quick inhales-exhales, then a deep inhale and hold for 2–3 sec.
• 5. Know Your Limits: Never dive deeper than your trained maximum.

🏆 Athlete's Nutrition and Recovery Guide

Regardless of the sport, these nutrition and recovery principles are universal and help achieve the best results.

Key Nutrition Principles:

• Protein: 1.6–2.2 g/kg of body weight per day. Consume protein every 3–4 hours to maintain a stable amino acid concentration in the blood.
• Carbohydrates: 4–7 g/kg per day (depending on the sport's intensity). Before training, choose fast carbohydrates; after training, choose complex ones.
• Fats: 0.8–1.2 g/kg per day. Prioritize unsaturated fatty acids (omega-3, olive oil, avocados).
• Hydration: 35–40 ml/kg of body weight per day. During training — an additional 500–1000 ml per hour.
• Micronutrients: Magnesium (300–400 mg/d), zinc (15–25 mg/d), iron (for athletes up to 18 mg/d), vitamin D3 (2000–4000 IU/d).

Recovery Protocol:

• Sleep: 8–9 hours of quality sleep. During sleep, growth hormone is released, which is responsible for muscle recovery and adaptation.
• Active Rest: 1–2 days per week without intense training. Light walking, swimming, or stretching exercises accelerate recovery.
• Massage and Self-Massage: At least 10–15 min per day for problem areas. A foam roller is an excellent tool for self-massage at home.
• Contrast Shower: 1 min hot water + 30 sec cold, repeat 3–4 times. Improves blood circulation and reduces muscle pain.
• Post-Workout Nutrition: Within 30–60 min after training — protein (25–40 g) + carbohydrates (50–80 g) for optimal recovery.

💊 Sports Supplement Usage Guide

Properly selected sports supplements can significantly improve training results, accelerate recovery, and reduce the risk of injury. Here is what sports nutrition specialists recommend:

🏥 Injury Prevention in Sports

Injuries are an inevitable part of sport, but proper prevention can reduce their risk. Here are universal injury prevention principles applicable in all sports:

• Warm-Up: 10–15 min of dynamic warm-up before every training session. The warm-up should imitate the main movements of the sport.
• Stretching after training: 10 min of static stretching after training helps maintain muscle elasticity and reduces the risk of injury.
• Progressive Load Increase: Never increase training load by more than 10% per week. Too-rapid progression is one of the most common causes of injury.
• Proper equipment: Footwear, protective gear, equipment — everything must be properly fitted and checked regularly.
• Rest Days: Muscles, tendons and bones need time to adapt. 1–2 rest days per week are essential.
• Hydration: Dehydration increases the risk of muscle strain. Drink water regularly throughout the day.
• Listen to your body's signals: Pain is not a sign of weakness — it is the body's warning. Sharp pain means you need to stop.

🧠 Mental Preparation for Competition

An athlete's success is determined 60–70% by physical preparation and 30–40% by psychological mindset. Here are mental strategies used by professionals to help achieve the best results during competition:

Before Competition:

• Visualization: 2–3 days before competition, mentally "review" your performance — from warm-up to finish. Visualization activates the same brain areas as real action.
• Creating a Routine: Create a consistent pre-competition routine — the same food, the same warm-up, the same music. Routine calms the nervous system.
• Goal Setting: Set process goals (e.g., "perform the technique well"), not only outcome goals (e.g., "win"). Process goals are within your control.

During Competition:

• Breathing Control: Deep diaphragmatic breathing (inhale for 4 sec, exhale for 6 sec) helps maintain calm and concentration.
• Focusing on the Present: Do not think about the past mistake or the future result. One action at a time — only what you are doing now.
• Positive self-talk: "I am ready", "I can do this", "I trust my training" — positive statements block negative thoughts.
