Participants will be subjected to three separate visits: control condition (30 min rest), moderate-intensity continuous exercise, and high-intensity interval exercise. The investigators will measure aerobic capacity using a cardiopulmonary exercise test (CPET) using indirect gas-exchange to derive subsequent exercise intensity and maximal oxygen uptake. The investigators will evaluate different measures of vascular function (Pulse-wave velocity, Flow-mediated slowing, microvascular function) before and after each condition.\n\nThe study will involve two groups of participants: healthy individuals and prehypertensive individuals. The investigators aim to establish the reliability and validity of less-established methods of vascular function assessment (flow-mediated slowing and microvascular function) against established measures (pulse-wave velocity). The acute response of vascular function to different exercise intensities has not yet been thoroughly researched using the aforementioned measures in individuals with similar characteristics to the proposed study cohort.",[81,82],"Prehypertension (Elevated Blood Pressure) or Hypertension","Healthy",[84,85,86],"aerobic exercise","vascular function","prehypertension","2025-12-15",{"date":89,"type":90},"2025-12-22","ACTUAL",{"date":92,"type":90},"2025-06-24",{"date":94,"type":75},"2026-06",{"name":5,"class":6},1]
