Effect of an Incremental Exercise to Exhaustion on Plasma Concentrations of Iron and Zinc in Athletes and Nonathletes

Abstract

Background: Trace elements are mineral nutrients involved in a lot of physiological processes during exercise. Some of the trace elements, such as iron (Fe) and zinc (Zn) play a major function in maintaining and regulating many of these processes. The variations in plasma Fe and Zn concentrations are dependent which follow intensity as well as the duration of the activity. Endurance exercise until exhaustion causes various changes in the body. Deficiencies in Fe and Zn can harmfully influence endurance performance. Objective: The purpose of the current study was to determine the effects of an incremental exercise until exhaustion on the plasma levels of Fe and Zn in athletes and nonathletes.
