This research accomplished to determine the hyponatremia frequency and its characters and risk factors related to hyponatremia patients in forces contributed in a one day maneuver to suggest the strategies of preventing it. Materials & Methods. This is a cross-sectional study in which 164 militants contributed in a one day maneuver in one of the military training centers in September 2008 were chosen by head accounting and were investigated by questionnaire and blood test before and after one day maneuver.

BMI was 24.03+2.1 in hyponatremia patients and 23.25+2.83 in non hyponatremia patients. Frequency of hyponatremia in non natives was %53. Current symptoms were weakness (88.3%), spasm (70.6%), fatigue (59.9%) and headache (58.7%). Conclusion. To prevent this problem among military forces during activity it is recommended to pay more attention to risk factors and physical activities to be programmed based on regulated activity-rest program and fluids consumption proportioned to the intensity of activity.
