      <content:encoded><![CDATA[Male endurance athletes were measure at rest and during progressive cycling in hyperoxia (30% O2), normoxia (21% O2), and hypoxia (15% O2). Starting at 0 W, power was increased 100 W in 5-minute increments in the exercise task.
Maximal cardiac output, VO2max, and maximal performance were diminished in hypoxia. Diminished COmax in hypoxia was affected both by decreased maximal stroke volume and heart rate. In hyperoxia, COmax was increased only slightly despite a correspondingly greater increase in VO2max. 
Implication: Changes in oxygen saturation in the atmosphere are only partially related to observed changes in parameters associated with cardiac output.

      <content:encoded><![CDATA[In einem Experiment mit 6 Ausdauersportlern wird festgestellt, daß das maximale Herzminutenvolumen unter akuter Hypoxie signifikant vermindert wird zusammen mit der VO2max und dermaximalen Leistung. Die verminderte CO2max wird unter Hypoxie beeinflußt durch ein verringertes maximales Schlagvolumen und eine verminderte Herzfrequenz. Unter Hyperoxie erhöht sich die CO2max nur leicht, ungeachtet einer erhöhten VO2max.]]></content:encoded>
