RESUMEN
BACKGROUND AND PURPOSE: The maintenance of postural control is influenced by the complexity of a given task. Tasks that require greater attention and cognitive involvement increase the risk of falls among older adults. The aim of the present study was to evaluate the adaptation of the postural control system to different levels of task complexity in physically inactive young and older women. METHODS: A cross-sectional study was conducted with adult women classified as physically inactive based on the results of the International Physical Activity Questionnaire. The participants were 27 young (20-30 years of age) and 27 older (60-80 years of age) women. Sway velocity of the center of pressure in the anterior-posterior and medial-lateral directions was calculated using a force plate under 6 conditions: standing directly on the force plate or on a foam placed over the force plate, eyes open or closed, and dual-task complexity with and without the foam. RESULTS AND DISCUSSION: A 2-way analysis of variance revealed that sway velocity increased in both groups when the task conditions were altered. The older women exhibited significantly greater sway velocity compared with the young women on all tasks. However, the patterns of postural control adaptation to the different levels of complexity were similar among all participants. CONCLUSIONS: In this study, the adaption of the postural control system to different levels of task complexity did not differ between physically inactive young and physically inactive older women. However, the physically inactive older women exhibited greater sway velocity compared with the young women.

Na tentativa de minimizar os processos degenerativos causados pelo envelhecimento percebe-se no slackline uma ferramenta com potencial para a melhoria da qualidade de vida da população idosa. O objetivo desse estudo foi analisar essa atividade em um grupo pertencente a um programa de atividade física orientada. A pesquisa descritiva utilizou como instrumentos: (1) diário de campo, (2) questionário (3) sistema de conversação e (4) teste de equilíbrio. Após as intervenções de slackline percebeu-se que ele fornece estímulos neuromotores interessantes para essa faixa etária, mas evidenciou-se que o aumento da autoconfiança, a motivação para realização da prática e maior inserção social desta população foram aspectos relevantes que justificam o tipo de intervenção.
In an attempt to minimize the degenerative process caused by aging is noticed in the slackline a tool with potential for improving the quality of the life of the elderly population. The aim of this study was to analyze this activity of a group belonging to a program of guided physical activity. The descriptive research used as instruments: (1) field diary, (2) questionnaire, (3) conversation system (4) one-step balance test. After the interventions of slackline it was noticed that it provides interesting neuromotor stimuli for this age group, but it became clear that the increase in self-confidence, motivation to carry out the practice and greater social inclusion of this population were relevant aspects that justify the type of intervention.
