Dynamic Balance Training by Balance Board for the Elderly
Focusing attention on falls, a dynamic balance training program using a balance board was carried out by a group of elderly persons for 3 weeks. We investigated dynamic balance and physical fitness factors before and after training. The subjects included 54 young adults and 58 elderly persons. Of these, the number of subjects assigned to the training groups were 27 and 35, respectively. We measured balance when a horizontal board was quickly inclined; various physical fitness factors were expected to be closely related to balance ability. The following results were obtained: (1) The dynamic balance of elderly persons was remarkably inferior to that of young persons. (2) Balance board training had a considerable effect for elderly persons. (3) The only physical fitness factor which showed a significant change after training in all subject groups was the hip joint extension limit. In addition, training increased the muscle strength of plantar flexion in elderly men, and the percentage of body fat decreased in elderly women. (4) The physical fitness factors which showed a significant correlation to dynamic balance differed between men and women, and between the young and the elderly.
