Exercise causes hemoconcentration, altering blood rheology. These changes in blood viscosity and viscoelasticity are significant after physical exertion in healthy individuals.

Area of Science:

  • Biorheology
  • Human Physiology
  • Exercise Science

Context:

  • Investigating the impact of physical activity on blood properties.
  • Utilizing controlled exercise protocols on a cycle ergometer.
  • Collaborative study between the Laboratory of Physiology and the Unity of Biorheology.

Purpose:

  • To examine hemorheological changes in healthy volunteers post-exercise.
  • To assess the effects of different exercise types on blood rheology.
  • To correlate hemoconcentration with rheological and biophysical parameters.

Summary:

  • Blood and plasma viscosities, thixotropy, and viscoelasticity were measured before and after exercise.
  • Biological markers including plasma proteins, osmolarity, and pH were analyzed.
