Dear Editor

Judging from our animal studies, there is an opportunity to improve performance by supplementing hepatic oxygenation from an enteric or even a peritoneal source.

The idea might be especially appealing to the armed forces but might conceivably be applied in a manner conducive to endurance sports. In our study oxygenating just half of the gut eliminated the compensatory increase in cardiac output induced by hypoxaemia [1].
