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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether short bursts of bodyweight exercise spread throughout the day, called exercise snacks, can improve muscle strength in older adults with possible sarcopenia. The trial enrolls 60 community-dwelling adults aged 60 and older who have weaker handgrip strength and slower chair-stand times. Participants are randomly assigned to exercise snacks, a home-based resistance training program, or a non-exercise control group for 8 weeks. Researchers measure handgrip strength and physical function before and after to compare the approaches.

What this could mean

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

Active substance
brief bodyweight exercise sessions spread through the day (exercise snacks) and a home-based resistance training program
What this could lead to
If exercise snacks work, they could offer a time-efficient way for older adults to build strength and stay independent without gym visits or long workouts.
What could go wrong
This is a small, 8-week study of 60 people, so any strength gains may be modest and may not last. Participants must stick to the routine, and bodyweight exercises may not challenge everyone enough to build muscle.

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: 1. Community-dwelling older adults aged 60 years or older. 2. Meeting the criteria for possible sarcopenia according to the Asian Working Group for Sarcopenia (AWGS) 2019 consensus. 3. Handgrip strength less than 28 kg for men or less than 18 kg for women. 4. Five-time chair stand test time of 12 seconds or longer. 5. Able to independently complete the exercise protocol and outcome assessments. 6. Provided written informed consent before participation. Exclusion Criteria: 1. Presence of contraindications to physical activity according to the Physical Activity Readiness Questionnaire (PAR-Q). 2. Participation in regular structured resistance training. 3. Use of medications or treatments likely to substantially affect muscle strength. 4. Participation in other interventional studies within the previous three months. 5. Unable to complete the five-time chair stand test independently.
