The purpose of this study was to investigate the effect of balance training frequency on functional improvement in elderly people over 75 years of age. The subjects comprised 14 institutionalized elderly people aged 84.9±5.8 years (mean±SD). The training program consisted of balance training, five times a week, for 1 year. Muscle strength, balance, agility, mobility and flexibility were assessed at the beginning and the end of the 1-year intervention period. The ratio of attended to scheduled sessions was used as an index of training frequency. The training frequency showed significant correlations to the improvement rate of knee extension strength (r=0.59) and modified SLR test (r=0.63). Discriminant analysis revealed correct prediction frequency of 43.3, 54.8% and 57.2%, for the maintenance of muscle strength, balance and flexibility, respectively. In conclusion, balance training frequency significantly affects the improvement of physical performance in frail elderly people. Elderly people would need training at least two or three times a week to maintain muscle strength, balance and flexibility.
