Exercise at 1.3 ATA: What a 2025 Study Found

A 2025 study by Hisamoto et al. looked at exercise in a 1.3 ATA chamber with 35% oxygen. That matters because O2 Box is designed around the same 1.3 ATA mild hyperbaric pressure range, giving this study a strong connection to the type of environment O2 Box is built to provide.

The study included 19 healthy men who completed stationary cycling exercise under three conditions: 0.7 ATA with 14.7% oxygen, 1.0 ATA with 21% oxygen, and 1.3 ATA with 35% oxygen.

In the 1.3 ATA mild hyperbaric condition, people could exercise harder before breathing became difficult. Their blood pressure stayed lower and their hearts worked with far less effort, meaning less overall strain on the heart and lungs. That is why O2 Box is positioned as a wellness tool designed to support oxygen availability, circulation, and whole-body recovery.

In simple terms, participants were able to handle more work before reaching a tougher breathing zone. That is why O2 Box is positioned as a wellness tool designed to support oxygen availability, circulation, and whole-body recovery.
