Effects of Water Inertia Load Training on Lower Limb Joint Moments, Gait, and Balance in Elderly Women

This study highlights that age-related neuromuscular changes negatively impact muscle strength, balance, joint mobility, and cardiovascular health, which in turn affect daily life activities and independence. In particular, aging leads to slower gait speeds and increased metabolic costs associated with shifting the body's center of mass, which are closely linked to functional decline in older adults. While previous studies have focused primarily on spatiotemporal variables like stride length and walking speed, there is a lack of research examining exercise interventions that analyze lower limb joint moments. This study aims to assess the effects of dynamic stability training using water inertia load on the distribution of lower limb joint moments, gait, and balance in older adults, ultimately providing valuable insights to support improvements in efficient gait function among the elderly.
