Outline of Final Research Achievements

This study elucidated effects of endurance training on coupling between arterial viscosity and left ventricular functions. First, the cross-sectional study found the quadratic function equation of relationship between cardiorespiratory fitness and arterial viscosity. Second, the interventional study, performed endurance training for three months, found that the endurance training increased cardiorespiratory fitness, but unchanged both arterial viscosity and left ventricular functions. From these results, there is most suitable value of cardiorespiratory fitness for maintaining arterial viscosity, but it is necessary to perform for a long time term for changing the arterial viscosity.
