title: The effect of aerobic exercise on blood and plasma viscosity on cardiac health club participants.
abstract: OBJECTIVE
  to analyze the effect of SJS aerobic exercise on blood and plasma viscosity.
  
  
  METHODS
  the study was performed on 30 subjects with an age span of 40 to 60 years. Subjects participated in SJS aerobic exercise of moderate intensity of 40 to 45 minutes duration, three times a week for 9 to 12 weeks. Five milliliters of blood were collected into K3EDTA container to assess blood and plasma viscosity prior to the program and following the completion of the SJS program. Blood and plasma viscosity was measured using Brookfield LVDV-III viscometer using rotational method principle.
  
  
  RESULTS
  this study demonstrated a significant decrease in blood viscosity (2.94%, p = 0.03) and insignificant decrease in plasma viscosity in subjects following SJS aerobic exercise compared to prior exercise.
  
  
  CONCLUSIONS
  this study proved that SJS aerobic exercise of moderate intensity of 40 to 45 minutes duration times a week for 9 to 12 weeks gave the benefit of lowering blood viscosity, which contributes to reducing the risk of coronary heart disease.
