Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Previous evidence showed hyperbaric oxygen can enhance aerobic and anaerobic performance during the exposure. The effect of continuous exposure of hyperbaric oxygen on performance was never evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In recent years, several options for physical performance enhancement by increasing blood oxygen content were explored. One option is increasing the number of red blood cells by blood transfusions. Another option is using the erythropoietin hormone. These methods showed an effective increase of maximal oxygen consumption rate (VO2MAX) by 10%. However, due to their inherent risks, the international sports associations banned their uses. A third option of training in high altitude environments, but this option was never proved to be effective.

Another strategy would be increasing the blood oxygen content by increasing the plasma dissolved oxygen concentration. This would only be possible using hyperbaric oxygen therapy -which includes inhaling 100% oxygen in a pressure higher than the normal atmospheric pressure.

Previous evidence showed hyperbaric oxygen can enhance aerobic and anaerobic performance during the exposure. These studies evaluated the effect during a single hyperbaric oxygen exposure. The effect of continuous exposure of hyperbaric oxygen on performance was never evaluated.

The study is designed as a randomized controlled study aiming to evaluate the therapeutic effects of hyperbaric oxygen therapy (HBOT) on the aerobic and anaerobic performance.

After signing an informed consent form, patients will be randomized into 2 groups: treatment and control group. Patients will be invited for baseline evaluations. All patients would be evaluated 2 times - at baseline and after 2 months of follow up, The evaluation will include physical examination, VO2MAX, muscle biopsy for mitochondrial function, aerobic function measurements, cognitive assessment, brain MRI, brain EEG.

Protocols:

Treatment: Patients will receive 40 daily sessions, 5 days/week, 60 minutes each with 5 minutes air break every 30 minutes, 100% oxygen at 2 atmospheres (ATA).

Control: Patients will receive 40 daily sessions, 5 days/week, 60 minutes each with 5 minutes air break every 30 minutes, 21% oxygen (air) at 1.01 ATA.

Upon completion of the study, control group would be offered to crossover and complete additional 40 sessions of 100% oxygen at 2 ATA. A third evaluation would be performed in case patients will complete the protocol.
