Can Extreme Endurance Running Damage Your Blood Cells?

Yes. A study of 23 trail runners found that ultramarathon races of 40 km and 171 km caused significant damage to red blood cells through inflammation and oxidative stress. The cells became less flexible and showed signs of accelerated aging after the races.

Red blood cells are the tiny disc-shaped cells that carry oxygen from your lungs to every part of your body. They need to be flexible enough to squeeze through the smallest blood vessels. When these cells get damaged or stiff, they cannot do their job as well. This study looked at what happens to these cells when runners push their bodies to the extreme, and the findings raise important questions about how much exercise is too much.

Does Oxygen During Exercise Training Help COPD Patients Who Don’t Need It at Rest?

Yes. This double-blind trial found that supplemental oxygen during high-intensity exercise training allows COPD patients to train harder and achieve greater improvements in endurance. Patients who trained with oxygen increased endurance time by 14.5 minutes compared to 10.5 minutes in the air group.

People with COPD often struggle with exercise, even when their oxygen levels at rest are normal. Researchers tested whether breathing extra oxygen during training would help these patients exercise more intensively and get better results.

Does Long-Term Oxygen Help COPD Patients with Moderate Low Oxygen Levels?

No. This landmark trial of 738 COPD patients found that long-term supplemental oxygen did not reduce death or hospitalization rates for patients with moderate oxygen desaturation. There was also no benefit for quality of life, lung function, or walking distance.

For decades, doctors have prescribed oxygen therapy to COPD patients with moderately low oxygen levels, assuming it would help. This large trial from the New England Journal of Medicine tested whether that assumption was correct.

Can Normal Oxygen Levels at Rest Hide Exercise Problems After COVID?

Yes. In this study, 43% of COVID pneumonia patients with normal oxygen at rest showed significant oxygen drops during a walking test. Normal blood gas readings at discharge cannot predict whether patients will struggle with exercise.

Researchers in Italy studied 70 patients ready for discharge after COVID-19 pneumonia. Even though all had normal oxygen levels at rest, nearly half experienced significant oxygen desaturation when they exercised. Most concerning, 83% of those who desaturated dropped below 90% oxygen during the test.

Can Rehabilitation Help People with Long COVID?

Yes. In this study, 30 people with Long COVID who completed a 6-week rehabilitation program showed significant improvements in exercise capacity, fatigue, breathing symptoms, and cognition. Walking distance improved by 112 meters, and there were no serious adverse events.

This UK study tested whether an adapted pulmonary rehabilitation program could safely help people struggling with lasting COVID-19 symptoms. The results showed clear benefits across multiple measures of function and quality of life.

Does Aging Reduce Oxygen Delivery to Your Tissues?

Yes. Oxygen transport into body tissues declines with age, primarily due to reduced heart output. However, Oxygen Multistep Therapy may counteract this decline by activating a “switch mechanism” that improves blood circulation for weeks, months, or even years.

This research describes how oxygen levels in your blood control a switching mechanism in your tiny blood vessels. When oxygen levels are high enough, your blood circulation improves and stays improved. When they fall below a critical threshold, circulation decreases for extended periods.

Does Breathing Extra Oxygen Really Improve Exercise Performance?

Yes. This meta-analysis of 51 studies found that breathing oxygen-enriched air has a large effect on time to exhaustion (effect size 0.89) and moderate effects on other performance measures. Higher oxygen concentrations correlated with greater performance improvements.

Athletes and fitness enthusiasts often wonder if supplemental oxygen can boost their workouts. Researchers analyzed decades of studies to find out. The results show clear benefits, especially for endurance activities.

Does Training While Breathing Extra Oxygen Improve Fitness?

Yes. This systematic review of 7 studies found that hyperoxic training improves performance with a large effect (Cohen’s d = 1.79) and oxygen uptake with a medium effect (d = 0.57). Training with 60-100% oxygen for 3-6 weeks produced notable improvements compared to normal-air training.

While scientists have studied altitude training (low oxygen) for decades, training with extra oxygen (hyperoxia) is less researched. This review analyzed what happens when people train while breathing oxygen-enriched air over several weeks.

Effects of Intermittent Hypoxia Protocols on Physical Performance

Does Intermittent Hypoxia Training Improve Athletic Performance?

Yes. This umbrella review of 22 systematic reviews analyzing 487 studies and 5,333 participants found that intermittent hypoxia protocols improve both aerobic and anaerobic performance, as well as muscular strength. Different hypoxia strategies work through different mechanisms.

Intermittent hypoxia (IH) involves alternating periods of low and normal oxygen levels. What started as a concern in sleep apnea has become a powerful tool for enhancing athletic performance. This comprehensive review examined all the existing systematic reviews on the topic.

Can Alternating Low and High Oxygen Improve Health?

Yes. This systematic review of 8 studies found that intermittent hypoxia-hyperoxia (IHH) improves exercise tolerance, peak oxygen uptake, cognitive function, and blood sugar control. The technique involves alternating periods of low-oxygen and high-oxygen breathing at rest.

Researchers have long known that brief exposures to low oxygen can trigger beneficial adaptations. This review examined whether replacing the normal-oxygen recovery periods with high-oxygen periods could enhance these benefits even more.

Does Hyperbaric Oxygen Therapy Help Athletic Performance or Recovery?

Not when used before or after exercise. This meta-analysis of 10 studies found no significant benefits from hyperbaric oxygen therapy before or after workouts. However, using it during exercise may help muscle endurance.

Athletes and fitness enthusiasts often look for ways to boost performance and speed recovery. Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized chamber. This systematic review examined whether timing matters for any potential benefits.

Exercise Intolerance and Impaired Oxygen Extraction in Long COVID

Why Can’t Long COVID Patients Exercise Normally?

Their bodies struggle to extract and use oxygen efficiently. This study of 59 long COVID patients found O2 pulse at only 79% of predicted values, with 41% showing reduced exercise capacity and significant chronotropic intolerance (inability to reach normal heart rate). The findings point to impaired energy metabolism as a key mechanism.

Chronic fatigue, exercise intolerance, and post-exertional malaise are among the most debilitating symptoms of long COVID, affecting 10-20% of survivors. Researchers used gold-standard cardiopulmonary exercise testing (CPET) to understand why these patients struggle with physical activity.
