Objetivos: Determinar los cambios que se producen en la condición física a lo largo de dos años de seguimiento en octogenarios y comprobar si un estilo de vida sedentario modifica estas variaciones. Metodología: La condición física de 182 sujetos (48 hombres, 134 mujeres) con una media de edad de 82,3 ± 2,3 años se evaluó mediante 8 test (adaptados de las baterías "Senior Fitness Test" y "Eurofit"). Se realizó un análisis de medidas repetidas entre los dos periodos de evaluación y para ver las diferencias de condición física entre los sujetos considerados sedentarios (permanecían sentados > 4 horas/día) y no sedentarios (permanecían sentados 4 horas/día sufrieron un descenso de la agilidad (p < 0,05). Se produjo una pérdida de velocidad y resistencia tanto en sedentarios como en no sedentarios (p < 0,05). Conclusión: En dos años de seguimiento, se producen cambios negativos en el nivel de condición física en personas octogenarias. Periodos prolongados de sedestación se traducen en una pérdida de agilidad. La velocidad de la marcha y resistencia parecen ser los componentes de la condición física más afectados por el proceso de envejecimiento en este grupo poblacional y su pérdida no viene determinada por las horas diarias de sedestación.
Objective: The aim of this study was to determine the changes in physical fitness over two years of following up in octogenarian people and to check whether a sedentary lifestyle modify these variations. Methods: Physical fitness of 182 subject (48 men, 134 women) with a mean age of 82,3 ± 2,3 years were evaluated using 8 different tests. A repeated measures analysis was carried out to see the differences between the two evaluation periods and to see the physical fitness differences between sedentary people (sit > 4 hours/day) and non sedentary people (sit 4 hours/day there was a decrease in the walking speed test between the two evaluations (p < 0.05). Moreover, there was a decrease of walking speed and endurance between the two evaluation periods in both sedentary and nonsedentary people (p < 0.05). Conclusion: In two years of following up, there are adverse changes in the level of physical fitness in octogenarians. Long periods of sitting time may translate into a loss of agility. Walking speed and endurance seem to be the components of physical fitness more affected by the ageing process in this population; and this loss is not determined by the hours of sitting per day.
