Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was to examine the additive benefits with combined grape seed extract (GSE) and L-citrulline supplementation on hemodynamic responses to dynamic exercise, 11 young, healthy males were recruited for this study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators aimed the additive effects of combined grape seed extract (GSE) and L-citrulline supplementation on hemodynamic responses to dynamic exercise, 11 young, healthy males were recruited for this study. Effects of 7 days of combined GSE with L-citrulline supplementation on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), cardiac output (CO), total vascular conductance (TVC), and oxygen consumption (O2) were examined at rest and during cycling exercise.
