4.   The players had their oxygen intake monitored as they rode stationary bikes.

5.   They say that randomly varying the amount of air coming in, from breath to breath, can decrease possible damage to tissues and maximize oxygen intake.

6.   In the lungs of cyclists, they measure the maximum oxygen intake in milliliters per kilogram of weight per minute.

7.   Jesse became comatose, his face swelled, his body was jaundiced and his oxygen intake dipped to dangerously low levels.
