Aims This study compared the effect of traditional exercise training and game-based exercise by TRAZER© on dynamic balance activities, vestibular ocular motor sensory (VOMS), falls efficacy scale-international (FES-I), and muscular performance in healthy older adults. Methods Twenty-two older adults (mean age: 77.59 ± 6.20 years) randomly divided into two groups (1) exercise training (ET) and (2) ET + TRAZER©. Both groups participated in one-hour exercise sessions, three days a week for 10 wk. The ET + TRAZER© group completed the three dynamic/agility balance assessments each day. Results The results showed the three TRAZER© assessments significantly increased in the ET + TRAZER© group. However, there was not a statistically significant difference between the groups for timed up and go (TUG), sit-to-stand (STS), and FES-I. Conclusions Our findings provided evidence that game-based exercise intervention improved muscular function and VOMS, especially dynamic balance and reaction time in older adults.
