The purpose of this study was to examine the relationship between ground reaction force parameters in sit-to-stand at the baseline or the amounts of change (Δ) over one-year follow-up period and incidence of “one or more falls” or “mobility limitations” during the follow-up period, in community-dwelling older adults. We performed analyses on 76 community-dwelling older adults, which included 29 men and 47 women, aged 65-84 years (73.5 ± 5.6 years) at baseline. Five parameters were measured: peak reaction force per body weight (F/w), which reflected the maximal downward push to rise the body upwards, two maximal rate of force development per body weight (RFD1/w, RFD9/w), which were an index of the capacity for rapid muscle force production, and two time-related parameters (T1, T2), which evaluated quickness of movement. Significant differences were found in ΔF/w (0.00 vs. 0.04 kgf • kg-1), ΔRFD1/ w (- 1.02 vs. 0.34 kgf/s • kg-1) and ΔRFD9/w (- 0.47 vs. 0.17 kgf/s • kg-1) between fallers and non-fallers, but no difference was found in any parameters at baseline. The subjects who reported incident mobility limitations performed lower in RFD9/w (8.26 vs. 10.42 kgf/s • kg-1), longer in T1 (453 vs. 301 ms) and T2 (1081 vs. 811 ms) at the baseline than the subjects who maintained good mobility. These results suggest that RFD9/w declines with incidence of falls, and may be able to predict onset of mobility limitations.
