During exercise, lungs take in air and transfer oxygen to the blood, which is then pumped by the heart to the muscles that need it. Oxygen pulse is the amount of oxygen put through this process with ...

Research on the effects of exercise in low-oxygen environments on the brain demonstrated that cognitive performance worsens when lower-than-usual amounts of oxygen are carried by the blood.

Low blood-oxygen levels were found to be the distinguishing factor that affected executive control-related neural activity and cognitive performance when exercise was performed in low-oxygen ...

Cardio fitness shows heart-lung strength, predicts longevity, and improves health at any age.

When physically demanding activities are performed at high altitudes or in other low-oxygen environments, excellent coordination, judgment, and decision-making are important. In some cases, such as ...
