Relationships between Vascular Endothelial Function and Physical Activity/Diastolic Blood Pressure in Male University Students

Abstract

[Purpose] To identify factors influencing vascular endothelial function in male university students. [Participants and Methods] A total of 34 healthy male university students were included to examine the relationships between vascular endothelial function (flow-mediated dilation: FMD) and the following parameters: body composition, blood pressure (systolic blood pressure: SBP; and diastolic blood pressure: DBP), and intensity-based physical activity (low: LPA; moderate: MPA; vigorous; VPA; and moderate to vigorous: %MVPA). [Results] The mean FMD was 8.1 ± 2.2%. FMD was significantly, positively correlated with VPA and %MVPA (r=0.432, 0.383, respectively). In the normal FMD group, it was significantly, negatively correlated with DBP (r=－0.445). Furthermore, VPA was significantly higher in this compared with the decreased FMD group. [Conclusion] Male university students’ vascular endothelial function was suggested to be influenced by the duration of high-intensity physical activity and DBP.
