The aim of this study was to examine the age-related differences on body composition, functional fitness and arterial stiffness in elderly women. 107 elderly women aged over 65 years old (65-69yrs; n=23, 70-74yrs; n=25, 75-79yrs; n=34, 80≤; n=25) participated in this study. Height and weight were measured. Body composition was assessed by BIA method. Bone mineral density was measured with right calcaneus by Sahara(Sahara 3.0, Holigic, USA). Six functional physical fitness tests were measured by SFT(senior fitness test). Vascular compliance was analyzed by VP-1000(Colin, Co., Japan). One-way ANOVA and Pearson’s correlation analysis were applied. There were significant differences on fat free mass(p<.01), total body water(p<.01), percent body fat(p<.05), and bone mineral density(p<.01) by age group. Significant differences were found for upper body flexibility(p<.01), grip strength(p<.0001), lower body strength(p<.0001), upper body strength(p<.0001), agility/dynamic balance(p<.0001), aerobic endurance(p<.0001), RbaPWV(p<.05), and LbaPWV(p<.05) between age groups. PWV was negatively related with fat free mass(p<.01), total body water(p<.01), lower body strength(p<.01), upper body strength(p<.01), aerobic endurance(p<.01). However, a positive relationship between PWV and agility/dynamic balance(p<.01) was found in elderly women. In conclusion, older age group had lower fat-free mass, bone mineral density and some of functional fitness tests compared to young age group. However, a higher PWV was found in older age group. To prevent musculoskeletal and cardiovascular disease in elderly people body composition, functional fitness and arterial compliance should be monitored regularly.
