Water-Inertia-Based Dynamic Stability Training for Balance and Postural Control in Healthy Young Women
Sponsor: Yuanyan Huang
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.

Water-Inertia-Based Dynamic Stability Training
Participants completed a supervised dynamic stability training program three times per week for 10 weeks (30 sessions), with each session lasting approximately 50 minutes. During training, participants wore a vest providing a total external load of 5 kg, consisting of approximately 4 kg of water in partially filled pouches and a 1-kg vest. Internal water movement allowed the external load distribution to change during exercise. Exercises were performed for three sets, with 12 repetitions per set during weeks 1-5 and 15 repetitions per set during weeks 6-10, with 30 seconds of rest between sets. Exercise content and any additional prescribed implement loads were matched to the stable-load intervention.
Stable-Load Dynamic Stability Training
Participants completed the same supervised dynamic stability training program three times per week for 10 weeks (30 sessions), with each session lasting approximately 50 minutes. During training, participants wore a stable weighted vest providing a total external load of 5 kg, consisting of approximately 4 kg of steel rods and a 1-kg vest. The steel rods were arranged to approximate the spatial loading configuration of the water pouches used in the water-inertia intervention. Exercises were performed for three sets, with 12 repetitions per set during weeks 1-5 and 15 repetitions per set during weeks 6-10, with 30 seconds of rest between sets. Exercise content and any additional prescribed implement loads were matched between groups.
