This cross-sectional study compares gait vertical ground reaction force and time characteristics of women over 30 years of age. Sixty women were divided into three groups according to their age (A 30-39, B 40-49, C 50-60). For research were used capacitive pressure insoles in the shoe. There laboratory survey was made and three stances of each leg were assessed. Six parameters had been chosen for monitoring, three vertical ground reaction force and three time parameters. F1 ‑ force peak during loading response, F2 – lowest force during decline between both peaks, F3 ‑ force peak during terminal stance, time of stance (t), tpr ‑ time of propulsive stage of stance (TSt, PSw), tab ‑ time of absorption stage of stance (LR, MSt). Percentage of body weight (%BW) was used. Statistics: ANOVA.
A tendency of gradual decrease in the size of ground reaction in mBW has been observed in dependence on increasing age in F1, F2 and F3. Significant differences were found between groups A and C for F1 in mBW (p=0.008) and for F3 in mBW (p=0.039). This manifests a natural development of gradual decrease in human force abilities depending on their age.
The average time of one stance increases with an increasing age; a significant difference has been found between groups A and C by 9.4% (p=0.006) and between B and C as well by 7.8% (p=0.02). This increase is primarily a consequence of prolonging time of stance propulsive part in elder aged groups.
