Influence of exercise on cognitive processing of older woman during dual-task balance: sixteen case reports

CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Background: Older adults require special attention during cognitive-motor tasks since automatic postural control is reduced. AIM: To analyze the effect of physical exercise on dual-task processing of healthy older women performing standing balance. Method: Sixteen healthy older women were assessed in a quiet standing position with eyes open/closed (single-task, EO, and EC) and with a cognitive task (dual-task, DT) using a Wii Balance Board. All individuals performed training (aerobic, strength, and virtual reality exercises) at moderate effort. Center of pressure (CoP) anteroposterior and mediolateral displacement were analyzed over time pre- and post-training. The Wilcoxon test was used to compare pre- and post-training. Results: Greater variability in CoP was observed pre- compared to post-training. In the DT, there was a significance decrease in post-training variability compared to pre-training (p
