Effects of Exercises on a Hard, Soft, and Sand Surface on Functional Outcomes of Community-Dwelling Older Individuals: A Randomized Controlled Trial

Abstract

This single-blind, randomized controlled trial compared the effects of Thai dance exercise training on hard, soft, and sand surfaces on the functional outcomes of 120 community-dwelling older adults (40 subjects/group). The subjects were involved in a Thai dance exercise program on each surface, according to their groups, for 50 min/day, 3 days/week, for 6 weeks. The functional outcomes were assessed prior to training, at Week 3, and Week 6 after training. Subjects showed a significant improvement in all functional tests at 3 and 6 weeks after training, particularly in those who were trained on a sand surface and a soft surface (7–30% improvement, p < .05). The improvement was especially demonstrated in the complex and demanding motor activities after exercise on a soft and sand surface. Aside from attempting to modify training programs on a hard surface, the current findings suggest an alternative and cost-effective program to promote the levels of independence and safety that can be applied easily in clinical, home-based, and community settings.
