The effect of one session endurance running (5000 m) on the level of serum electrolytes

The purpose this study was the effect of one session endurance running (5000 m) on the level of serum electrolytes. In this quasi-experimental، 14 male runners participated in the test، voluntarily. After warm-up، subjects ran distances of 5،000 meters in 23 minutes and participated in the second blood sampling. Photometer and spectrophotometer video device to determine blood electrolytes were used. 5،000-meter run at Tehran''s climate caused significant change in serum sodium (p=0/039، t=2/30). Serum calcium levels also rose significantly in the amount of 7/1 percent (p=0/005، t=-3/37). the 5000-meter run، Increases in sodium and calcium in the blood serum and Reduces the amount of potassium.
