Outline of Final Research Achievements

Data obtained using ground reaction force (GRF) in the two-step forward test (2ST) could reveal useful parameters of dynamic balance in locomotive syndrome (LS). This study aimed to examine the contribution of dynamic balance parameters to the risk of LS and the usefulness of these parameters as indicators in the exercise intervention for reducing the risk of LS. As a result, we found that the multi-regression model consisted of peak GRFs in the sagittal and frontal directions and the mean velocity of the center of pressure in the sagittal direction 201 ms after landing in the 2ST showed the highest contribution ratio to the risk of LS. Furthermore, the results of whole-body vibration (WBV) training intervention in older adults with a grade 1 risk of LS revealed that the WBV training group showed significant improvements in mean and peak velocities in all directions, 201 ms after landing in the 2ST.
