Acute Power Training Effects in Older Adults
Belgium42 participantsStarted 2026-04-20
Plain-language summary
The goal of this clinical trial is to learn how older adults respond to power training when the level of fatigue during exercise is different. Power training means performing fast movements with moderate loads to improve strength, power and mobility.
The main questions the study aims to answer are:
* How does the level of fatigue during power training acutely affect strength, movement, and muscle function?
* How does it affect recovery, muscle soreness, and how hard the exercise feels?
Researchers will compare three power-training sessions with different fatigue levels to see which approach may be safest and most effective for older adults.
Participants will be healthy older adults aged 65 to 85 years. Each participant will complete three supervised exercise sessions on a leg press machine. The sessions will take place about one week apart.
During the study, participants will:
* Perform power training on a pneumatic leg press machine
* Complete strength and mobility tests before and after exercise
* Provide small blood samples to measure body responses to exercise
* Rate how hard the exercise feels
* Report muscle soreness for up to two days after exercise
The results may help researchers design safer and more effective power-training programs to improve strength, mobility, and recovery in older adults.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Maximum Voluntary Contraction (MVC)
Timeframe: Measurements will be taken before exercise (baseline), 5 minutes after each training session, and 24 hours after each session.
