Study examined the current knowledge of the sensitivity of some blood components and electrolytes in serum and blood of athletes as a result the practice of different sports, as it was during the study survey of thirty athletes from male healthy and exposed to Voltages first by 9.6 km / hour and a slope of 4% and the second rate of 20.8 km / h and slope 20 %, as the samples were collected venous blood of these athletes was estimated by some blood components and trace elements (Concentration of hemoglobin, Volume of packed blood cells, red blood cell count, potassium, sodium, calcium, chloride) in addition to measure the number of heart rate and body temperature of these athletes were compared with (20) sample of healthy individuals as control group.The study results showed obvious changes in the concentrations of these variables above, as it showed Concentration of hemoglobin significant increase was (16.69 ± 3.4) and (16.60 ± 3.7), respectively, inthe effort I and II compared with the control group (14.00 ± 2.3), while showing Volume of packed blood cells significant increase arrived (52.68 ± 4.1) and (50.26 ± 5.6) compared with the control group (44.00 ± 2.3),The concentrations of electrolytes showed clear differences as it showed a potassium rise is morally reached (4.55 ± 0.29) and (4.81 ± 0.46) mmol / l compared with the concentration in the control group (4.9 ± 0.90), whilecalcium showed a significantly increase total (93.30 ± 1.6) and (87.50 ± 4.3) compared with the control group (98 ± 4.6), either the number of strikes heart showed an increase in athletes and effort during the first andsecond hit (90,75%) in addition to the high temperature objects these athletes when they are the first and second voltage.
