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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looked at whether regular exercise and speaking two languages can help older adults keep their language skills and thinking abilities. 233 healthy but inactive older adults took part in a 26-week home-based high-intensity interval training program. Researchers measured fitness, language tasks, and cognitive function before and after the program to see if exercise made a difference.

What this could mean

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

Active substance
Home-based high-intensity interval training (HIIT)
What this could lead to
If successful, this could show that regular exercise helps maintain language skills and thinking speed in older adults.
What could go wrong
This is an observational and early-stage intervention study. Results may not apply to everyone, and the exercise program may be hard to stick with long-term.

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

233 people

The number who actually took part.

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

60 to 85 years

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

Inclusion Criteria: * Non-smokers for at least 5 years prior to enrollment. * Normal or corrected-to-normal vision and hearing. * No diagnosed language impairments (e.g., dyslexia, stuttering). * No illness or disease that would prevent safe participation in high-intensity interval training (HIIT). * Self-reported not meeting global physical activity recommendations (i.e., \<150 minutes/week of moderate-intensity physical activity). * Norway only: Written health certificate from the participant's general practitioner confirming eligibility for participation. Exclusion Criteria: * Any cardiovascular, metabolic, respiratory, neurological, kidney, liver, or cancer disease that would prevent safe participation in HIIT. * United Kingdom only: Severe electrocardiogram abnormalities (e.g., ST depression, long QT, heart block, wide QRS). * United Kingdom only: Elevated blood pressure at screening (systolic \>160 mmHg and/or diastolic \>90 mmHg).
