What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study investigates whether combining high-intensity exercise with nitrate-rich beetroot juice can improve blood vessel function and fitness in post-menopausal women, who face increased heart disease risk. Participants are randomly assigned to one of four groups: high- or moderate-intensity exercise, plus either nitrate-rich beetroot juice or a placebo. Over one month, researchers measure changes in vascular health and aerobic capacity to see if this combination offers greater benefits than standard exercise alone.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
nitrate-rich beetroot juice and high-intensity exercise
What this could lead to
If successful, this could lead to a simple, non-drug approach—combining specific exercise intensity with beetroot juice—to reduce cardiovascular risk in post-menopausal women.
What could go wrong
This is a small, early-phase study with only 40 participants, so results may not apply broadly. The effects of beetroot juice and exercise intensity may be modest or not sustained over time.
