Effect of severe exercise on plasma catecholamines in differently trained athletes
Article Abstract:
Severe exercise may affect sprinters and runners differently. Researchers evaluated the oxygen demand on the bodies of eight male runners and nine male sprinters after completing a severe treadmill exercise test. The catecholamine content, such as norepinephrine sulfate and epinephrine sulfate, rose in both groups but more significantly among the sprinters. Compared to the endurance athletes, sprinters had also accumulated higher oxygen deficits after exercise.

Effects of iron repletion on blood volume and performance capacity in young athletes
Article Abstract:
This article examines the relationship between iron supplementation, blood volume, and aerobic performance in elite athletes with nonanemic iron deficiency. Findings indicate that iron repletion increased maximal aerobic capacity and oxygen consumption but did not significantly impact the volume of red blood cells in athletes.

Exercise with the intensity of the individual anaerobic threshold in acute hypoxia
Article Abstract:
The determination of the individual anaerobic threshold (IAT) during incremental treadmill tests in normoxia is presented. Relative intensities in normoxia and acute hypoxia are equivalent when endurance exercise is performed.
