How short power-training sessions affect muscle power and movement in older adults.
Official title: Acute Neuromuscular and Physiological Responses to Different Velocity Loss Thresholds During Power Training in Older Adults
Run by Hasselt University · NCT07522398 · Data updated 2026-11-12
This test will try three leg-press power-training sessions with different fatigue levels to see which approach is safest and most helpful for adults aged 65–85.

Is this trial a fit for you?
✓Likely a good fit
Healthy, independently living adults aged 65–85 who have not regularly done resistance training in the past year and who have physician clearance for exercise are ideal candidates.
✕Probably not a fit
Those with unstable heart or neurological disease, acute infection, recent lower-limb injury or joint replacement, or recent use of NSAIDs or certain supplements may be excluded and unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Healthy adults aged 65 to 85 will complete three supervised power-training sessions on a pneumatic leg press about one week apart, with each session designed to produce a different level of fatigue. Researchers will measure acute changes in strength, movement, and neuromuscular function before and after each session, and will track recovery, muscle soreness, and perceived exertion. Participants will not need prior resistance training experience and will be screened for cardiovascular and musculoskeletal safety. The crossover design lets each participant serve as their own control to compare immediate responses to varying fatigue targets.
Why it matters
Potential benefit: If successful, the findings could guide safer and more effective power-training plans that improve leg power and mobility while minimizing soreness or overfatigue in older adults.
How similar studies have gone: Previous research shows power training can improve strength and mobility in older adults, but acute comparisons of different fatigue levels during power training are less well established.

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.
