Olympic cyclists put themselves in near-death situation: study

Last Updated: Tuesday, August 8, 2000 - 00:00

Kevin Norton, of the university of south Australia, said that studies of Australian cyclists including Olympic and world champion gold medallists had uncovered amazing biochemical changes in the blood during strenuous exercise.

“We put a catheter in an artery and every 15 seconds we take blood and have a look at the level of Oxygen in their blood,” said Norton, of the university's School of Physical Education, Exercise and Sport Studies.

At rest, these guys have virtually 100 percent of Red Blood Cells saturated with Oxygen.

When they're exercising really strenuously, like in a team pursuit or an individual pursuit, their level of Oxygen saturation drops down to about 84 or 85 percent.
