The Science

Oxygen is the most important nutrient when it comes to athletic performance.

O2 + Glucose = ATP (ultimate energy molecule for the body)

The body’s rate of fatigue is heavily dependent on oxygen. If the body goes into an oxygen deficit while training, large amounts of lactic acid is produced resulting in an increased rate of muscle fatigue. Oxygen reduces muscle fatigue by slowing down the lactic acid build up.

The History

The principles of martial arts teaches us that our focus and strength stems from how we breathe. The more oxygen taken in, the bigger the PUSH. Pure O2 is an intra-workout in the sporting arena which means it is used during or just before intense challenges. Oxygen naturally calms the mind during stressful situations reducing the build-up of cortisol enhancing clarity, focus and form. With mind and body receiving optimum oxygen supply, the ideal state is created for intense, focused explosiveness.


The Journal of Science and Medicine in Sport, found that with cyclists, training at moderate altitude,

breathing hyperoxic gas (concentrated oxygen) vs. ambient air allowed for higher training intensities. This higher intensity training resulted in significant improvements in maximal steady state power output and the time to complete a 120 kJ performance test. References, D.M. Morris, J.T. Kearney, E.R. Burke.

These findings show that breathing supplemental oxygen improves training intensities or explosive bursts. If this is done often enough muscle memory will kick in, allowing higher performance levels more regularly. Cyclists require quick bursts of energy for a break away or sprint. By fuelling the mind and muscles with 95% pure oxygen, the body has more than enough O2 to create ATP to get ahead. The high concentration of oxygen will also assist after intense climbing where altitude is high and you literally out of breath.


The applications for improvements in maximal steady state power output are specific to sports

involving a combination of stamina and power. The goal is to maximise the amount of work done in the SHORTEST space of Time. Intensity is essential for results and is measurable as work divided by time OR power. The more work done in less time, or the higher the power output, the more intense the effort. Supplemental oxygen not only creates the ideal state for explosiveness but also substantially reduces recovery time, as more often than not, the body’s oxygen requirements increase more than the increase in intensity. The effect of this is having to stop to catch you’re breath. Supplemental oxygen will help shorten this process such that you can get back quicker and more focused.


The nature of these sports don’t allow for much breathing during the different actions, as it is

virtually impossible to move the diaphragm while lifting something heavy. Because of this limitation the competitor literally holds their breath throughout the duration of the move or action. By breathing a higher concentration of oxygen before attempting heavy lifts, extends the time the body’s oxygen levels are depleted allowing more time to finish the lift or series of heavy lifts. Where there are a series of heavy lifts under time constraints, Pure O2 can be used in-between lifts to recover quicker and shake off any dizzy spells.

Building Muscle

The more reps achieved, the more muscle gained. Pure O2 will help achieve more reps by

significantly improving maximal steady state power output which will result in increased muscle size and strength. Another benefit of training with supplemental oxygen is that there are no calories or stimulants in it. This allows for intense training without the intake of calories to help lean out.

On Stage – Posing

Using the technique of oxygen loading (refer below) before walking on stage will ensure a calm

confident state of mind and see you hold stronger poses more frequently. Posing requires, energy, muscle contraction and limited breathing. By flooding the body with oxygen prior to walking on stage the athlete is in an ideal state for longer muscle contractions with limited breathing movements. Normal air indoors can contain oxygen levels anywhere between 17-19%. Pure O2 is 95% pure oxygen which ensures maximal oxygen intake before exertion.

If competing in any event, please consider the altitude of the location

Making sense of it…

In a nut shell, the higher the altitude the less the oxygen in the atmosphere. Typically coastal cities range between 20 – 21% in oxygen levels while areas like Johannesburg can range between 18 -19%. Climatic conditions as well as pollution also play a factor and in most cases can be worse than these ranges. Now a 2% change in oxygen levels might not sound like a lot, but as a percentage it is about a 10% deficit to anyone moving from a coastal region.

High Altitude Effects on Athletes

The symptoms of competing at altitude varies per individual, however these are the common effects:

  • Heavy/Rapid breathing during warm ups.
  • Needing more breaks during training sessions to catch your breath
  • Loss of focus or a lack “ooomph” in performance
  • Light headedness or slight dizzy spells during exertion
  • The air feels thin or dry

Who does it affect?

Athletes living in LOW altitude regions and competing in high altitude areas e.g. Johannesburg

For those moving from any coastal region to compete in JHB, the unfortunate reality is that you are moving from oxygen rich levels i.e. coastal cities (20%-21%) to lower oxygen levels (18%-19%), which can result in less than optimum performance levels. Even with a week of acclimatisation the feeling of fatigue and breathlessness becomes more evident in high intensity sports.

Challenge: Low oxygen levels at higher altitudes

Solution:  Oxygen Loading – simulating an oxygen rich environment where training was completed. (refer below)

Athletes living and competing in HIGH altitude areas e.g. Johannesburg

Studies have shown that training at high altitudes and competing at sea level have great performance benefits i.e. moving from a low oxygen environment to a high oxygen environment. Living and training in high altitude areas has its advantages IF you going to compete at lower altitudes. If however you will be competing in a high altitude area, its best to create an oxygen rich environment during competition, replicating competing in a low altitude area.

Challenge: Oxygen levels too low to simulate a higher oxygen environment during competition

Solution:  Oxygen Loading – simulating an oxygen rich environment to maximise the effects of high altitude training. (refer below)

Oxygen Loading

Oxygen loading is done a few minutes before the start of a physically intense routine, time trial or taking the stage. It’s going to take 5 minutes in total. During a 5 minute period, every 20 seconds we recommend trying a 1 sec burst of Pure O2.

  • Press down the nozzle for 1 sec and breathe in. After you have let go of the nozzle, continue to breathe in. The lungs take about 3 sec to fill completely with air. We want, 1 sec out of those 3 sec to be with Pure O2. After you take a deep breath with a 1 sec burst of Pure O2, hold your breath for 3 seconds then breathe out.
  • Every 20 seconds, over the period of 5minutes we want you to do the above.
  • This translates to 3 shots every minute and a total of 15, 1 sec shots over the 5 min period.
  • This is a good start for oxygen loading. If you get light headed, it’s because your body isn’t used to the high oxygen levels. Simply increase the time between the shots, so do 2 shots every minute or even 1 if it helps.

This is a guide and should be tweaked according to tolerance levels. It’s best to have tried oxygen loading prior to an event and not for the first time on comp day. If dizziness is experienced which can occur simply revert to breathing as normal and the feeling will dissipate within seconds.

Pure O2 creates the ideal state to PEAK performance levels naturally. Peaking at the right time is the difference between being an athlete and a spectator. The only active ingredient in Pure O2 is 95% pure oxygen, infused in mint to enhance focus, control and explosiveness.

When do I use PureO2?


2 X 3sec bursts before a sprint, break or climb

3 X 3sec bursts for quick recovery after a sprint or climb

HIGH ALTITUDES – use the oxygen loading technique 20 min before and 5min before the start of the race. Use 2sec bursts whenever feeling fatigued or out of breath during the race.


Use the oxygen loading technique before any challenging routine and thereafter use 2sec bursts in-between heavy reps to help gain focus, balance and form. The goal is to maintain maximal steady state power output

HIGH ALTITUDES –  use the oxygen loading technique 20 min before AND 5min before the start of the competition. Use 2sec bursts whenever feeling fatigued or out of breath in-between routines.


Use the oxygen loading technique 5 min before any routine or BIG lift. Before attempting to pick up a weight inhale 2 X 3sec bursts and go for it. Together with oxygen loading and the last 2 deep breaths of Pure O2 the body should be holding enough oxygen to get the lifts through.

HIGH ALTITUDE – use the oxygen loading technique 20 min before AND 5 min before the competition. Use 3 sec bursts whenever feeling fatigued or out of breath in-between lifts.

Building Muscle

The goal is to increase the total rep count. Pure O2 should be used later on in the workout where form is starting to slip. Use 2X2sec bursts before attempting difficult sets.

For a 1 REP MAX use the powerlifting technique i.e. use the oxygen loading technique 5 min before the lift. Before attempting to pick up a weight inhale 2 X 3sec bursts and go for it.

On stage - Posing

Oxygen loading should be used 5 min before walking onto stage every time. The last 2 breaths should be at least 2 X 2sec inhalations. This will calm the nerves and help hold the poses longer under breathing constraints.

HIGH ALTITUDE – start oxygen loading 20 min before AND 5 min before going on stage.
