NCT ID NCT07522398

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 Results may not be published yet.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.

Summary

This study looks at how different levels of fatigue during power training affect strength, muscle function, and recovery in healthy adults aged 65 to 85. Participants will do three supervised leg-press sessions, stopping when their movement speed drops by 10% or 30%, or matching the total work of the 30% session but stopping at 10%. Researchers will measure muscle strength, activation, soreness, and blood markers to find the safest and most effective training approach.

What this could mean

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

Active substance
Power training at different velocity loss thresholds (10% vs 30%)
What this could lead to
If successful, this could help design safer and more effective power-training programs to improve strength and mobility in older adults.
What could go wrong
This is a small, early-stage study with only 42 participants, so results may not apply to all older adults. It measures short-term responses, not long-term benefits.

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 42 people

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

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.

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: Participants must: * Be 65 to 85 years old. * Be able to live independently and perform everyday activities without help. * Not have regularly done resistance or strength training in the past year. * Be able to understand study instructions and communicate in the study language. * Have a recent statement from their treating physician confirming that their heart and blood vessels are healthy enough to safely take part in this study. Exclusion criteria Participants will not be eligible if they have any of the following: * Unstable heart disease, neurological disease, acute infection, or fever. * Use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, in the 5 days before the study. * Use of whey protein, casein, or amino acid supplements in the month before the study. * Acute or chronic injuries to the legs or lower body muscles. * Any injury or condition that prevents safe leg extension exercises. * Recent lower-limb joint replacement (less than 6 months ago). * Dependence on walking aids. * Current participation in another interventional trial.
