Effects of Water-Inertia-Based dynamic stability training on dynamic balance and Single-Leg postural control in healthy young women: a randomized controlled trial
NCT ID NCT07812103
First seen Sep 10, 2026 · Last updated Sep 10, 2026
Summary
This randomized controlled study evaluated the effects of a 10-week dynamic stability training program using a mobile water load compared with a mass-matched stable load in healthy young women. Thirty participants were randomly assigned to either water-inertia-based unstable-load training or stable-load training. Both groups completed the same supervised exercises three times per week, using vests with the same total external mass; the main difference between groups was whether the load inside the vest was mobile or stable. Outcomes were assessed before training, after 5 weeks, and after 10 weeks. The study evaluated dynamic balance, postural sway during single-leg stance, and other physical-performance outcomes to determine whether mobile water loading produced different training adaptations from stable loading.
