Effect of acute maximal aerobic exercise upon the trace element levels in blood.

This study was carried out in order to determine the effect of acute maximal aerobic exercise on the copper and zinc levels in blood. The study was participated by 16 healthy male university students with an average age of 19.44+/-1.63. There were 5 cc blood samples taken from the participants before and after they had been subjected to aerobic loading process (20 m shuttle run). The copper and zinc levels in the blood samples were determined by the use of Anodic Stripping Voltammetry (ASV) technique. The data obtained were evaluated by simple t test and SPSS software. The results revealed the fact that the blood Zn levels of the participants increased and Cu levels decreased with statistical significant extent (p<0.01) after maximal aerobic loading. There found no correlation between the maximal aerobic power levels (Max VO2) of the participants and their resting copper and zinc blood levels. However blood zinc and Max VO2 levels of the participants were positively correlated after maximal aerobic loading. The participants were fed on a zinc and copper free diet six week prior to the program. They were also asked not to use copper and zinc containing vitamins during this period.
