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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 spreading plyometric (jump) training into short, frequent sessions—five times a week—improves leg muscle function and rope-skipping performance more than doing the same total volume in fewer, longer sessions twice a week. About 60 rope-skipping athletes will follow one of these two schedules for 8 weeks while continuing their regular training. Researchers will measure leg strength, endurance, explosive power, and sport-specific performance before and after, along with fatigue and muscle soreness, to see which scheduling approach works better.

What this could mean

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

Active substance
Microdosed plyometric training (short, frequent jump-training sessions)
What this could lead to
If effective, this training approach could help athletes improve leg power and sport-specific performance with less fatigue, potentially optimizing training schedules.
What could go wrong
The trial is small (60 athletes) and results may not apply to other sports or non-athletes. Differences in outcomes could be minimal, and the training may not be superior to traditional methods.

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 60 people

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

Started

Jun 2026

Expected to finish

Aug 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 25 years

Sex

Anyone

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: * \* Rope-skipping athletes with at least 1 year of rope-skipping training experience * Able to complete regular rope-skipping training and all study-related testing procedures * No severe lower-limb sports injury within the previous 3 months * No cardiovascular disease, neurological disease, or other contraindication to exercise * Willing to participate voluntarily and provide written informed consent * For participants who are minors, written informed consent must also be obtained from a parent or legal Exclusion Criteria: * \* Participation in additional systematic strength training or plyometric training during the intervention period * Insufficient adherence to the prescribed training program * Injury, physical discomfort, or another condition occurring during testing or intervention that prevents continued participation in the study
