Oxygen and Athletic Performance: The Science Behind Endurance, Stamina, and Recovery

---

Whether you’re a competitive athlete or a dedicated weekend warrior, one factor shapes every workout, every race, and every recovery: oxygen. Your muscles can’t generate sustained energy without it. Your cells can’t clear waste without it. And when oxygen runs short, performance falls — fast.

This article pulls together what we know about oxygen and athletic performance, including a look at the clinical research conducted on Activated Stabilized Oxygen (ASO®), the formula used in OxygenSuperCharger™.

Why Oxygen Is the Engine of Athletic Performance

Your body runs on a fuel cycle. Carbohydrates stored as glycogen in the liver and muscles are converted to glucose during exercise, and glucose is then burned for the energy your muscles need. What makes that conversion possible? Oxygen.

This process — aerobic metabolism (from the Greek aer, meaning air; metabolism requiring oxygen) — is the backbone of endurance performance. The more efficiently your cells can take in and use oxygen, the longer and harder you can work before fatigue sets in.

When oxygen demand outpaces supply, your body shifts to anaerobic metabolism (energy production without oxygen). Energy is still produced, but at a cost: lactic acid accumulates in the muscles. The familiar burn, the cramping, the rapid breathing — these are all signs of lactic acid buildup. Performance is reduced. Recovery takes longer.

This is why oxygen isn’t just one factor among many. It’s the factor on which everything else depends.

Understanding VO2 Max

The gold standard for measuring aerobic capacity is VO2 max — maximal oxygen uptake. It expresses the maximum amount of oxygen your body can use during intense exercise, measured in milliliters of oxygen per kilogram of body weight per minute.

A higher VO2 max means your cardiovascular and muscular systems are more efficient at delivering and using oxygen. It’s the single best predictor of endurance performance, and it’s what separates elite athletes from recreational ones.

You can improve VO2 max through training — specifically, aerobic conditioning that increasingly stresses the cardiovascular system over time. High-altitude training is another well-documented approach: at elevations above 7,000 feet, reduced oxygen availability triggers the body to produce more oxygen-carrying red blood cells. When those athletes compete at lower elevations, they bring that enhanced capacity with them. It’s the reason East African marathon runners — many raised in Kenya’s Rift Valley or Ethiopia’s highlands — have long dominated distance events.

The Three Energy Systems Every Athlete Relies On

Understanding how your body produces energy helps clarify why oxygen matters across all sports, not just endurance events.

Aerobic metabolism uses oxygen to convert nutrients into energy. It’s the primary system for sustained effort — distance running, cycling, swimming, and team sports. It’s efficient and produces no harmful byproducts.

Anaerobic lactic metabolism kicks in during intense bursts of effort — sprinting, heavy lifting, high-intensity intervals. It generates energy without oxygen, using glucose exclusively, with lactic acid as the byproduct. This system can sustain effort for seconds to a few minutes before fatigue forces you to slow down.

Alactic anaerobic metabolism powers explosive, very short efforts — a maximal jump, a 40-yard dash, a single heavy lift. It produces energy without oxygen and without lactic acid, drawing on stored ATP in the muscle. It lasts only a few seconds.

Even in “anaerobic” sports, oxygen plays a critical role — in recovery between efforts, in clearing lactic acid between sets, and in maintaining output across repeated explosive actions.

What the Research Shows on ASO®

Three clinical studies have been conducted on the Activated Stabilized Oxygen (ASO®) formula. Here is an honest summary of each.

Study 1: Sprint Performance (Brunei Time Trial Study)

Citation: Zaheer, H.D., Zaheeruddin, H., & Hennessy, D. Sports Medicine & Research Centre, Department of Youth & Sports, Brunei Darussalam.

Full title: “Preliminary Study Into The Use of ASO®/O2-Power™ Stabilized Liquid Oxygen As an Ergogenic Aid for Sprinters In a Competition/Heat Scenario.”

Nine athletes participated in a double-sprint protocol. Half received ASO® stabilized liquid oxygen; the other half received a placebo.

The results were modest but directionally favorable. The mean finish-time differences between ASO® and placebo groups were marginal overall. However, looking at individual results, five of the nine athletes who received ASO® improved their second sprint times compared to their first. In the placebo group, only one of nine athletes improved on the second sprint.

The researchers concluded that while ASO® did not produce a dramatic across-the-board performance enhancement, it appeared to help athletes sustain consistent output across repeated efforts — maintaining their first-sprint performance into the second sprint, rather than declining.

Honest framing: This was a small pilot study with nine participants. The results are preliminary and should not be overstated. What they suggest is a possible recovery and consistency benefit between efforts — which, as the researchers noted, matters in competition where margins are small.

Study 2: VO2 Max and Blood Lactate (The Most Significant Study)

Citation: Pericleous, N.Y., M.Sc., ACSM.

Full title: “The Concentration of Lactate in the Blood and the Improvement of the Maximum Reception of Oxygen after the Ingestion of ASO® Solution.”

This is the most rigorous of the three studies. Thirty-five athletes of varying ages, weights, and sports backgrounds participated. Each completed two exercise tests: 40 minutes of continuous running and a 400-meter run. In some trials, they ingested ASO® before exercise; in others, they did not.

The findings were consistent across all 35 subjects: blood lactate levels decreased in every time-trial period when ASO® was consumed, compared with trials without it. VO2 max also showed improvement.

The researcher concluded that ingestion of ASO® considerably affects blood lactic acid tolerance and improves VO2 max.

Honest framing: Thirty-five participants is a meaningful sample for this type of study. The consistency of the lactate result — every subject, every time trial — is notable. However, this study has not been replicated in the peer-reviewed literature, and larger independent studies would be needed to definitively establish the finding.

Study 3: Blood Oxygen Saturation

Citation: Aker, J.D., Ph.D., M.S., P.A., P.P.A.

Full title: “Capillary Microscope Oxygen Saturation Test conducted using Activated Stabilized Oxygen (ASO®) Solution at 100% Full Concentration.”

This study measured blood oxygen saturation directly using capillary microscopy. Every test subject who consumed ASO® showed an initial increase in oxygen saturation ranging from 35% to 58%. That elevation lasted a minimum of 30 minutes and up to 45 minutes in the majority of subjects (57.1%). Subjects who received the placebo showed no measurable change in oxygen saturation.

Honest framing: The measurable increase in blood oxygen saturation is the most directly relevant finding for athletes. If oxygen saturation increases meaningfully in the 30–45 minutes following ingestion, there is a plausible mechanism for the lactate and VO2 max findings in Study 2. The study was conducted by a single researcher and has not been independently replicated.

A full summary of all three studies is available in our Clinical Research PDF, and the research is also discussed on our dedicated Research page.

How ASO® Differs from Other Oxygen Supplements

Not all oxygen supplements work the same way — and the differences matter.

Most older-generation stabilized oxygen products use sodium chlorite chemistry. They contain no actual bio-available oxygen until a chemical reaction occurs in the stomach. They’re caustic, must be diluted before use, and have an alkaline pH that can burn skin and tissue.

OxygenSuperCharger™ uses a different technology entirely. The oxygen is already bio-available in solution — no stomach-acid reaction required. The pH is approximately 7.4, matching the body’s own blood pH. It can be taken directly under the tongue without dilution.

This matters for athletes because sublingual absorption is faster and more direct than waiting for a chemical reaction in the stomach.

Practical Notes for Athletes

Timing: Take OxygenSuperCharger™ at least an hour before or after meals. Food impurities will consume some of the available oxygen before it reaches your cells. Many athletes take it 30–60 minutes before training or competition.

Dosage: The recommended starting point is 5 drops three times daily, gradually increasing to 30 drops three times daily for the original formula. The Ultra Strength formula is 25% stronger, so the equivalent maximum is 23 drops. Athletes with high-demand training schedules often adjust dosage to their individual needs.

Consistency: Blood oxygen levels benefit from sustained supplementation rather than single-use doses. Athletes in the studies took ASO® before exercise as part of a consistent protocol.

Stacking: OxygenSuperCharger™ can be added to pure water and consumed. Do not mix it into juice, sports drinks, or protein shakes — the oxygen will interact with and neutralize impurities in those beverages before it reaches your cells.

The Bottom Line

Oxygen is not a marginal variable in athletic performance. It is the central mechanism behind energy production, endurance, and recovery. Training, altitude adaptation, and breathing technique all work because they improve the oxygen available to your cells.

The clinical research on ASO® — while preliminary and in need of larger independent replication — consistently points in one direction: measurable increases in blood oxygen saturation, reduced blood lactate, and improved VO2 max in athletes who consumed it before exercise.

OxygenSuperCharger™ is not a shortcut, and we don’t frame it as one. It’s a bio-available oxygen supplement with real research behind it, used by people who take their performance and recovery seriously.
