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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 trial tests whether the type and intensity of exercise affect blood sugar control in pregnant women with gestational diabetes. Participants will complete four separate exercise sessions: low-intensity resistance training, low-intensity aerobic training, moderate-intensity resistance training, and moderate-intensity aerobic training. Researchers will monitor blood glucose continuously during and for 24 hours after each session, and also measure insulin sensitivity before and after. The goal is to see if resistance training or moderate intensity offers better glucose regulation than aerobic training or low intensity.

What this could mean

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

Active substance
Acute exercise sessions comparing resistance training (weightlifting) and aerobic training (cardio) at low and moderate intensities
What this could lead to
If it works, this could point toward specific exercise prescriptions that help pregnant women with gestational diabetes manage blood sugar and insulin sensitivity.
What could go wrong
This is a small, early study with only 23 participants, and it tests single exercise sessions rather than a full program, so the results may not translate to long-term glucose control or apply broadly.
