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

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.

Summary

This study tested whether eccentric training (a type of exercise that lengthens muscles) done in a low-oxygen (hypoxic) chamber or with creatine supplements could improve blood sugar control, muscle strength, and fitness in people with type 1 diabetes. 28 adults with type 1 diabetes for at least 10 years took part. The goal was to see if these approaches could help manage the disease better.

What this could mean

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

Active substance
creatine supplementation
What this could lead to
If successful, this could point toward a way to improve blood sugar control and muscle strength in people with type 1 diabetes using exercise and supplements.
What could go wrong
This is a small, completed trial with only 28 participants, so results may not apply to everyone. The interventions are behavioral and dietary, not a cure.
