This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research is testing how your blood vessels respond right after you do moderate-intensity exercise versus high-intensity interval training. The study compares people with normal blood pressure to people with slightly elevated blood pressure (called prehypertension). By measuring blood vessel function before and after different types of exercise, researchers want to understand whether certain workouts are better at improving vascular health in people at risk for heart disease.
Scientists know that exercise is good for heart health, but they don't fully understand which types of exercise work best for improving blood vessel function, especially in people with elevated blood pressure. This study will help clarify whether moderate or high-intensity interval training produces better immediate improvements in how well blood vessels work.

First, you'll attend a screening visit in the morning where staff will measure your blood pressure, height, and weight, and ask you about your physical activity level and health history. If you qualify, you'll return for three study visits spaced 72 hours apart, each at the same time of day. At each visit, you'll perform different types of exercise on equipment while researchers measure how your blood vessels respond using ultrasound and other non-invasive tools. Before each visit, you'll need to avoid strenuous exercise, caffeine, and alcohol, arrive well-rested, and eat a light meal 2–3 hours beforehand.
