Background: The purpose this study was the effect of one session endurance running (5000 m) on the level of serum electrolytes.
Materials and methods: 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.
Results: 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).
Conclusion: the 5000-meter run, Increases in sodium and calcium in the blood serum and Reduces the amount of potassium.

Background and purpose: In recent years, psychological and physiological effects of music on athletic performance have become an attractive field of research. The present study investigates the effect of various kinds of music on mood characteristics and performance accuracy in skilled and semi-skilled female basketball players. Methods: The population for this quasi-experimental study consisted of skilled players (League) and semi-skilled players (PE students). Seventy-two female basketball players (36 skilled and 36 semi-skilled) were selected randomly and assigned to different groups (exciting music, relaxation music, and favorite music). Data was collected in two days using Brunel mood scale and 5-value Zachary scale for measuring the accuracy of basketball free-throw. Results: ANOVA results show that listening to music improved mood characteristics of participants significantly regardless of their skill level (p=0.012). The interaction of test and type of music was significant on mood variables (p=0.01). Favorite music was more effective than exciting music in improving mood properties (p
