Understanding Your Lungs as an Athlete

Why Do Lungs Matter So Much for Endurance Performance?

During intense exercise, your oxygen consumption can increase from about 250 mL/min at rest to over 5,000 mL/min—a twentyfold increase. According to research published in the European Respiratory Journal, the respiratory system can become a limiting factor in highly trained athletes, particularly during high-intensity efforts.

Your lungs perform two critical functions during running:

• Oxygen delivery: Pulling oxygen from the air and transferring it to your bloodstream

• Carbon dioxide removal: Expelling the metabolic waste produced by working muscles

When either function is compromised—whether by environmental factors, seasonal challenges, or suboptimal respiratory health—performance suffers.

How Does Endurance Training Change Your Respiratory System?

Consistent aerobic training creates measurable adaptations in your respiratory system. A 2023 study in the Journal of Sports Science and Medicine found that trained endurance athletes demonstrate:

• Improved respiratory muscle endurance

• Better ventilatory efficiency (more oxygen extracted per breath)

• Enhanced ability to maintain breathing patterns under fatigue

However, these adaptations take time and can be supported through targeted respiratory wellness strategies.

Training Your Respiratory System

Can You Actually Train Your Lungs Like You Train Your Legs?

Yes—and it's increasingly recognized as a missing piece in many training programs. The respiratory muscles, particularly the diaphragm and intercostals, respond to training stimulus just like skeletal muscles.

Research from the University of British Columbia has shown that inspiratory muscle training can improve time-trial performance and reduce perceived effort during high-intensity exercise. This suggests that respiratory fitness is trainable and directly impacts performance outcomes.

What Breathing Techniques Help Runners Most?

Several evidence-based breathing strategies support better running economy:

• Diaphragmatic breathing: Engaging your belly rather than shallow chest breathing maximizes lung capacity

• Rhythmic breathing patterns: Coordinating breath with stride (such as a 3:2 inhale-to-exhale ratio) promotes efficiency

• Nasal breathing for easy efforts: Builds aerobic base while filtering and humidifying air

• Controlled exhalation: Fully emptying lungs allows for greater fresh air intake

Practice these techniques during easy runs before implementing them in harder efforts.

Common Breathing Challenges for Runners

Why Do I Sometimes Feel Like I Can't Get Enough Air?

That sensation of breathlessness during hard efforts is normal—it's your body responding to increased CO2 levels and signaling for more ventilation. However, chronic or exercise-limiting breathlessness may indicate underlying factors worth addressing.

Common contributors include:

• Environmental irritants (pollution, pollen, dust)

• Seasonal respiratory challenges

• Insufficient warm-up before intense efforts

• Running in cold, dry air without proper adaptation

• Exercise-induced airway narrowing (consult your healthcare provider if persistent)

How Does Air Quality Affect My Running?

Air quality significantly impacts respiratory comfort and performance. The American Lung Association notes that ground-level ozone and particulate matter can affect breathing during outdoor exercise, particularly for those with respiratory sensitivities.

During poor air quality days, consider:

• Running earlier in the day when pollution levels are typically lower

• Choosing routes away from heavy traffic

• Moving workouts indoors when AQI exceeds healthy thresholds

• Supporting your respiratory system with targeted wellness strategies

Natural Support for Respiratory Wellness

What Ingredients Support Lung Health for Athletes?

Several natural compounds have traditional use and emerging research supporting respiratory wellness:

Mullein Leaf: Used for centuries in traditional herbalism, mullein supports natural mucus clearance and promotes comfortable breathing. Its soothing properties make it popular among those seeking respiratory support.

NAC (N-Acetyl L-Cysteine): This amino acid derivative supports the body's production of glutathione, a powerful antioxidant. Research suggests NAC may support healthy respiratory function and mucus consistency.

Elderberry: Rich in antioxidants, elderberry supports immune function—particularly relevant for athletes whose training loads can temporarily affect immune response.

Vitamin D: Often called the "sunshine vitamin," adequate vitamin D levels are associated with healthy respiratory and immune function. Many athletes, especially those training indoors or in northern latitudes, may benefit from supplementation.

How Can Supplements Support My Respiratory System?

For runners seeking comprehensive respiratory support, BetterLungs Capsules offer a doctor-formulated combination of seven key ingredients including Mullein Leaf, NAC, Vitamin D, Maritime Pine Bark Extract, and Elderberry. Formulated by Dr. Chris Jackson, PharmD, this daily supplement is designed to support lung health and respiratory wellness for active individuals.

Those who prefer faster absorption may consider BetterLungs Mullein + Chlorophyll Tincture, which delivered impressive results in clinical testing. In a 60-day Citruslabs clinical trial, 77% of participants reported clearer airways, and 81% reported less frequent coughing—results particularly relevant for athletes training through seasonal transitions.

All BetterLungs products are third-party tested by ISO Certified Labs, manufactured in a GMP certified facility, and backed by a 365-day money-back guarantee.

Optimizing Performance Through Better Breathing

When Should Runners Focus on Respiratory Health?

Respiratory support should be a year-round consideration, with particular attention during:

• Pre-season buildup: When training volume increases and respiratory demands grow

• Seasonal transitions: When environmental allergens and air quality fluctuate

• Race preparation: When you need your respiratory system performing at its best

• Recovery periods: When immune function may be temporarily compromised from training stress

Consistency matters—supporting respiratory wellness daily builds the foundation for breakthrough performances.

What's a Simple Respiratory Wellness Routine for Athletes?

A practical daily approach combines:

• Morning: BetterLungs supplement with breakfast

• Pre-run: 5 minutes of diaphragmatic breathing exercises

• During run: Conscious breathing patterns matched to effort level

• Evening: BetterLungs Detox Tea for respiratory support and relaxation (caffeine-free, perfect for sleep quality)

This routine addresses respiratory wellness from multiple angles without requiring significant time investment.

Frequently Asked Questions

Does cold air damage my lungs when running in winter?

Cold air doesn't permanently damage healthy lungs, but it can cause temporary discomfort and bronchospasm in some individuals. When you breathe cold, dry air during exercise, your airways work harder to warm and humidify it before it reaches your lungs. Supporting your respiratory system year-round may help maintain comfortable breathing during cold-weather training. Consider using a buff or gaiter to pre-warm air on extremely cold days.

How long before a race should I start focusing on respiratory support?

Begin supporting respiratory wellness at least 4-6 weeks before your goal race. This allows time for consistent supplementation to support your system, for breathing technique improvements to become habitual, and for any seasonal respiratory challenges to be addressed. Many athletes using BetterLungs products report noticing benefits within 2-4 weeks of daily use.

Can respiratory support help with altitude training or racing?

At altitude, lower oxygen partial pressure means your respiratory system must work harder. While no supplement can substitute for proper altitude acclimatization, supporting overall respiratory wellness may help your body adapt more comfortably. Research on altitude training and respiratory function continues to evolve, but maintaining healthy lung function provides a foundation for altitude performance.

Are there specific foods that support lung health for athletes?

Anti-inflammatory foods rich in antioxidants appear beneficial for respiratory wellness. These include leafy greens, berries, fatty fish rich in omega-3s, nuts, and colorful vegetables. Hydration also matters—adequate fluid intake helps maintain optimal mucus consistency for healthy airways. Combined with targeted supplementation like BetterLungs, a nutrient-rich diet supports comprehensive respiratory wellness.

Should I breathe through my nose or mouth when running?

Both have their place. Nasal breathing during easy efforts promotes efficient air conditioning and may support aerobic development. During harder efforts, mouth breathing allows greater air volume. Many coaches recommend a combination approach—nasal breathing during warm-up and recovery efforts, transitioning to mouth or combined breathing as intensity increases.
