Descent is assisted by a weighted sled sliding down a line, the ascent may be by pulling up along the line or swimming without fins. We found that the end tidal partial pressure of oxygen decreased the longer the breath was held during underwater exercise and was lower in synchronized swimmers compared to controls when the order of BH began with the short BH periods.
