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
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 Results may not be published yet.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 This study
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

Summary

This trial tests a 6-week training program for elite judokas, involving high-intensity cycling in simulated altitude (like 3000 meters) with or without eccentric cycling—where a motor drives pedals backward and athletes try to slow them down. The goal is to see if this innovative approach improves muscle strength and judo performance. Participants are male and female judokas aged 16-23 from French training centers. Strength and performance are measured before and after the program to evaluate its impact.

What this could mean

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

Active substance
High-intensity cycling training in simulated altitude (hypoxia), with or without eccentric cycling (motor-driven pedals requiring braking actions)
What this could lead to
If effective, this training method could enhance muscle strength and judo performance, offering a new strategy for elite athletes.
What could go wrong
The trial is small (30 participants) and early-stage, so results may not generalize. Training at altitude may cause fatigue or discomfort, and benefits might not translate to competition outcomes.
