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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 alternating between regular and simulated higher-altitude training improves physical performance and physiological adaptations more than training at a fixed altitude alone. Sixteen elite race walkers from Yunnan Province will be randomly assigned to one of the two training strategies. Researchers will measure changes in body composition, lung function, heart structure, aerobic capacity, and muscle strength before and after the training period.

What this could mean

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

Active substance
alternating altitude training (behavioral intervention)
What this could lead to
If effective, alternating altitude training could offer a new way to boost endurance and performance in elite athletes.
What could go wrong
This is a small, early-stage study with only 16 participants, so results may not apply broadly. The benefits may be small or not translate to competition settings.

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

About 16 people

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

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Sep 2026

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.

Ages

18 to 26 years

Sex

Male participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

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

Inclusion Criteria: * Male and female elite race walkers aged 16-26 years. Registered athletes from the Yunnan Provincial Race Walking Team. Long-term residents of high-altitude regions with regular altitude training experience. Healthy and medically cleared to participate in high-intensity training and hypoxic exposure. Able to complete the prescribed training program and all outcome assessments. Provided written informed consent before enrollment. For participants younger than 18 years, written informed consent will also be obtained from a parent or legal guardian. Exclusion Criteria: * Any cardiovascular, respiratory, metabolic, neurological, or other medical condition contraindicating exercise or hypoxic exposure. Musculoskeletal injury or illness affecting normal training or performance within the previous three months. Current use of medications or supplements that may substantially influence physiological adaptation or exercise performance. Failure to complete the intervention or outcome assessments according to the study protocol. Withdrawal of informed consent at any time during the study.
