title: [Hemorheological changes in hot and humid environment].
abstract: OBJECTIVE
  To observe the changes in hemorheology of human under hot and humid environment.
  
  
  METHODS
  Ninety soldiers serving in the Nansha Islands were divided into veteran group, recruit group and urapidil-treated recruit group, all of whom were required to complete 3 000-meter running exercise in 20 min in hot and humid environment. Their hemorheology were examined before and after the exercise.
  
  
  RESULTS
  There were significant difference in the hemorheology between the 3 groups (P<0.05) both before and after the exercise, and the changes were most obvious in the veteran group followed by the new recruit group and urapidil-treated recruit group. No significant differences in the plasma indexes were detected between the 3 groups.
  
  
  CONCLUSIONS
  Hot and humid environment causes obvious changes in the hemorheology, for which veterans and recruits have different tolerances and adaptabilities. Uradipil may help lower the magnitude of the the hemorheological changes after exercise by reducing body metabolism.
