FEMINIZATION
This study aims to investigate the effects of dual-task physical–cognitive the training on body balance (BB), gait performance (GP), lower limb muscle strength (LEMS), and cognitive performance (CP) in a group of cognitively normal older adult women (Aging brings a series of biological, psychological, and functional changes [Cognitive changes caused by aging are characterized by a reduction in synaptic density and the dendritic arborization of cortical neurons [The relationship between motor tasks such as GP and BB with cognition is controlled by muscle modulation processes, known as muscle synergy [In the clinical area, the use of simultaneous tasks that compete for limited resources (i.e., dual-task interference) is presented as a strategy to identify cognitive deficits [In general, a low CP and GP [The purpose of this study was to examine the effect of a 12-week physical–cognitive DT training program on GP, BB, LEMS, and cognition in a group of cognitively normal older adult women. We hypothesized that, after 12 weeks of intervention, members of the physical–cognitive DT training would indicate better performance in all tests. In turn, comparatively, members of the DT group would present better results in the evaluations after 12 weeks of follow-up than members of the control group. We justify the single inclusion of older adult women in the study because both in Brazil, as well as in the city where this investigation was carried out, there is a multifaceted phenomenon called the feminization of aging [
