What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how arm crank exercise (like pedaling with your arms) changes blood flow in people with peripheral artery disease (PAD) compared to healthy adults. Researchers will measure blood vessel function and oxygen levels in the calf before and after exercise. The goal is to understand if arm exercise can improve circulation in the legs without causing leg pain.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2025

Expected to finish

Jul 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * If female, must be postmenopausal without hormone replacement therapy; * Non-smokers; * With a body mass index (BMI) not exceeding 30 kg/m²; * With calf skinfold thickness below 20 mm, due to the interference of adiposity in the penetration of light from the NIRS probe, and oxygen saturation in the finger \>95% to ensure that impaired pulmonary gas exchange does not affect oxygen saturation measurements in the calf; * Not using classic antioxidants or vitamin supplements; and * Physically capable of performing an exercise session. * For the group of participants with PAD, in addition to the criteria mentioned above, they must have a confirmed diagnosis of the disease, characterized by an ankle-brachial index (ABI) lower than 0.90 in one or both legs, exhibit symptoms of claudication during walking, and be physically capable of performing an exercise session to participate in the project. Exclusion Criteria: * Only participants who discontinue their participation in the study protocol will be excluded from the sample
