ClinConnect Summary
This study is looking at how two different power-training intensities affect older adults. In a randomized setup (participants, the people giving care, and the people measuring the results don’t know which group you’re in), people 60 and older will train for 16 weeks at either low-to-moderate intensity (40-60% of a standard strength measure called 1RM) or moderate-to-high intensity (65-80% of 1RM). After a 2-week familiarization period, participants are randomly assigned to one of the two training levels. The main goal is to see whether these training styles help improve power (how quickly muscles can generate force) and prevent functional decline as we age.
Who can join? Adults aged 60+ who are generally healthy, not doing regular resistance training in the last 3 months, and who can safely participate in exercise. They should not be using steroids or similar substances, and they must complete all study phases and most training sessions. The study will take place in Porto Alegre, Brazil, at the Federal University of Rio Grande do Sul, with about 70 participants. Expected assessments include muscle power and strength tests, rate of force development, muscle size by ultrasound, walking and stair-climbing tests, and a short cognitive screening (MoCA). Results aren’t available yet; enrollment started in April 2025 and the study aims to finish in December 2025.
