Changes in postural balance associated with a woman's aging process

Age-related changes in static balance in older women aged in their early sixties to their late eighties: different aging patterns in the anterior–posterior and mediolateral directions

“…In the ML direction, the sway amplitude had a significant weak positive correlation with age ( Figure 2 , right-hand panels), whereas the amplitude of regulatory activity did not have a significant correlation with age ( Figure 3 , right-hand panels). This slightly increased sway amplitude with increasing age in the ML direction is consistent with the recent report of Brech et al (2022) in which statistically significant difference was found in the ML directional CoP displacement between the women in their sixties and eighties. However, our present results are partly contrary to a previous study ( Prieto et al, 1996 ) in which no significant differences were found in any of ten measures based on the ML directional component of the CoP (including the CoP RMS ) between the younger (26.4 ± 4.9 years) and older (68.0 ± 1.3 years) adult groups.…”

“…Although numerous attempts have been made to compare the balance abilities of older individuals to those of younger people (see Quijoux et al, 2021 for a review), a few attempts have been made to examine the age-related changes in balance throughout old age. Recently, Brech et al (2022) , who evaluated the age-related changes on static balance in 400 women aged 50–89 years, have reported that the older women in their eighties exhibited greater displacement and range of the center of foot pressure (CoP) in the mediolateral (ML) direction and faster planar mean velocity of CoP than the women in their fifties and sixties. However, because Brech et al (2022) have examined only displacement-related measures (i.e., displacement and range of CoP) for each of the anterior–posterior (AP) and ML directions, direction-dependency of the age-related changes in static balance is still ambiguous.…”

Therefore, in the present study, our aim was to cross-sectionally investigate how static balance in older women aged in their early sixties to their late eighties changes throughout the aging process, in both the AP and ML directions, using multiple measures (i.e., displacement-related measure, acceleration-related measure, and frequency-related measure) that enabled us to capture a wide range of spatio-temporal features of postural control.…”

Comportamiento morfo-funcional entre dos grupos de mujeres físicamente activas de la tercera edad

“…Se cree que la similitud en el nivel de AF incidió en las variables del control postural en relación con el envejecimiento; Adicionalmente, esto nos permite interpretar que la equivalencia del nivel de AF alcanzaría efectos positivos más grandes sobre el control postural en los sujetos con mayor edad de modo que podría ralentizar la pérdida de esta funcionalidad con el avance de la edad. Nuestros resultados difieren con Du Pasquier et al, (2003) quienes analizaron que en bipedestación (BEOA) la velocidad en el eje AP se incrementa con la edad; los resultados de este hallazgo proporcionan información que podría precisar las alteraciones del equilibrio postural relacionado con el envejecimiento; así mismo, los hallazgos recientes de Brech et al,(2022) señalan que con el avance de la edad ocurre un aumento en las oscilaciones promedio en el desplazamiento en los ejes AP y ML, rango ML y AP, velocidad y el área total, los cambios en estos parámetros permiten evidenciar el declive del equilibrio postural en esta etapa de la vida. Igualmente, ocurre con el equilibrio dinámico.…”
