Abstract

Objective: Exergaming has been introduced in safe and beneficial intervention for the elderly. However, no study has examined exergaming-based interventions for the elderly that last several years. Therefore, we investigated the effectiveness and safety of a 12-week intervention using step training with exergaming for the elderly (12-week study). Moreover, we conducted an exergaming-based intervention for 3 years (3-year study). Materials and methods: 12-week study: Forty-two elderly persons participated in this study. Using an in-house developed exergaming protocol, a step training was performed for 15 min/session twice a week for 12 weeks. We investigated post-intervention changes in motor functions, successful step-rate, the intensity of exercise, which was evaluated using Borg scale (Rating of Perceived Exertion). 3-year study: An intervention using exergaming was conducted for 12 weeks by 20 elderly participants. Two courses/year of exercise were performed at 3-month intervals. This was continued for 3 years. The exercise continuation rate, its influence on motor functions were investigated. Results: 12-week study: Lower-limb muscle strength, balancing capacity, and whole body reaction time significantly improved in the exercise group. The mean score on Borg scale was 12 ± 2 on the first day of the step exercise and 9 ± 2 on the final day. 3-year study: Exercise was continued in 16 out of the 20 subjects. The Timed Up and Go Test, duration of one-footed standing, and quadriceps strength significantly improved. Conclusion: The results of the present study showed that exergaming provided an appropriate exercise intensity for the elderly and safely improved motor functions. The exercise continuation rate in the 3-year study was high. Improvements in motor functions may contribute to the prevention of falls.
