Jumping vs. lifting: which exercise keeps seniors stronger?
NCT ID NCT06821321
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different exercise programs—high-speed resistance training and plyometric jump training—affect muscle stiffness, jumping ability, and everyday activities in older adults living independently. Researchers measured changes in leg muscle and tendon stiffness using special ultrasound imaging. The goal was to understand which type of exercise might help older people stay active and mobile.
