In summary, the proposed setup is a vertical wind tunnel, where you train in a downdraft. The OP is asking about the effects of air resistance, which is quite different than the title.

If you want to produce low concentrations of Oxygen, it may be cheaper (the mechanics of it) to obtain Nitrogen to dilute the O2 level in the air.
Needless to say, Health and Safety would be a huge consideration here. You would need continuous and reliable checking.
If you want to drop the ambient pressure to the equivalent of high altitudes you may find the physical design could be expensive.
PS I don't like the idea of a re-circulating system. Using fresh air would avoid the problem of hypoxia and CO2 (or even CO) poisoning that you can get with a closed system.

What shortcomings of currently available training methods are your trying to address, that would justify building such a facility?matt56 said:

Maybe look for a Hypobaric Chamber (not Hyperbaric Chamber) facility near you, and see if you can rent time there. That would be much safer than you trying to McGyver some setup of your own.matt56 said:

At low speeds air resistance/drag is negligible. I think the reduction in air pressure would have a much greater impact on the persons physiology.
Not sure if it helps but in some countries pressures chambers are used to treat MS. Perhaps you could borrow one?

Which was why I asked if the setup was to prepare for high altitudes. It didn't occur to me that the OP was concerned that air resistance would have any effect on jogging or pushups, which would be minimal if not actually unmeasurable.CWatters said:

We need more info about the purpose of all this. To reproduce the effect of low air pressure on drag you could just compensate with fan-assist. By far the cheaper option would be to follow a runner with a large fan, run at a suitable speed - arrived at by calculation. The sort of fan that's used to propel hovercraft could do the job.
Alternatively, why not run on a treadmill with a fan pushing you backwards - again with the appropriate air speed to produce the drag you'd expect at high altitude.
But what sort of drag are we talking about for a runner at 10km/hr?

@matt56 Have you been put off by an over -enthusiastic response? PF is like that.

FAQ: Low Air Pressure Training (exercise)
What is low air pressure training?
Low air pressure training, also known as altitude training, involves exercising in an environment with reduced oxygen levels to simulate high altitude conditions. This type of training is believed to improve athletic performance and increase endurance.
How does low air pressure training work?
Exercising in low air pressure environments causes the body to produce more red blood cells, which are responsible for carrying oxygen to the muscles. This adaptation helps the body to utilize oxygen more efficiently and can lead to improved performance.
What are the benefits of low air pressure training?
The benefits of low air pressure training include increased endurance, improved cardiovascular health, and better oxygen utilization by the body. It can also help athletes acclimate to high altitude environments and improve their performance in these conditions.
Who can benefit from low air pressure training?
Athletes and individuals looking to improve their endurance and athletic performance can benefit from low air pressure training. It can also be helpful for individuals with certain medical conditions, such as chronic obstructive pulmonary disease (COPD) or asthma, as it can improve lung function.
Are there any risks associated with low air pressure training?
While low air pressure training can have numerous benefits, it also carries some risks. Exercising in high altitude environments can put strain on the body and may lead to altitude sickness, dehydration, or other health issues. It is important to consult with a medical professional before beginning any low air pressure training program.
