Diferenças nos aspectos cognitivos entre idosos praticantes e não praticantes de exercício físico

Contrasting performance between physically active and sedentary older people playing exergames

The increase in life expectancy associated with the increase in chronological age and less active people helps in the appearance of chronic and degenerative diseases. The encouragement of physical exercises contributes to older people abandoning sedentarism and preventing such diseases. Exergame is a promising alternative, for making exercise a pleasurable activity.In this study, we compared the performance of physically active older people with sedentary older people in exergames.Participants were 83 older adults over 65 years of age, of both sexes, divided into 2 physically active older people (AG) and sedentary older people (CG) groups. The participants performed a task through an exergame called "MoviLetrando" that uses the score, number of hits, number of omissions, and an average time of hits as an evaluation. A characterization questionnaire was applied, with information about sex, age, marital status, economic class, self-rated health, time of use of electronic games, a questionnaire on the practice of physical activity, and the Brunel Mood Scale.There was a higher exergame score in AG than in CG (P = .003), in the number of correct answers (P = .012). The number of omissions was lower in AG than in CG (P = .023). The mean time of correct answers was lower in AG than in CG (P = .013). The regression analysis revealed a significant finding F (3, 82) = 11.06, P < .001 and showed a prediction ability of 26.9% (r = .269). Three variables remained significantly associated with the score: physical activity was marginally significant (β = .19, P = .06), age (β = -.403, P < .001), depression (β = -.212, P = .028).Physically active older people perform better when compared with the sedentary older people. Age, depression, and physical activity influence the performance in exergame.

Descriptive data in different paper-based cognitive assessments in elderly from the community Stratification by age and education

Cognitive aging is dynamic and heterogeneous in elderly, thus adequate tools such as paper-based tests are relevant to describe the cognitive profile of this population.

Cognitive function of elderly residents in long-term institutions: effects of a physiotherapy program

The increase in the size of the elderly population demands new knowledge about the process of healthy and active aging. Cognitive disorders are directly associated with aging, and therefore represent a public health problem. A longitudinal and interventional study with a quantitative approach was performed with the aim of analyzing the effects of a physical therapy program aimed at health promotion on the cognitive ability of institutionalized elderly women. Data was collected using a sociodemographic and clinical form and the Mini Mental State Examination (MMSE) at three time points (baseline, after 10 interventions and after 20 interventions). The health promotion program consisted of 20 recreational group activities in weekly meetings lasting an hour. Statistical analysis used the paired Student's t-test and Analysis of variance, with a significance level of p<0.05. The sample consisted of 24 elderly persons, with a mean age of 80.04 years. The results showed improvement in the performance of the elderly, both in overall MMSE score (T0=19.22 vs. T2=28.33, p=0.01) and in the evaluated subcategories "time orientation" (T0=3.35 vs. T2=3.57, p=0.02), "record" (T0=2.61 vs. T2=2.95, p<0.01), "memory recall" (T0=1.78 vs. T2=2.71, p<0.01), "read and execute" (T0=0.43 vs. T2=0.67, p=0.01) and "copy diagram" (T0=0.26 vs. T2=0, 48, p=0.02). These findings suggest that physical therapy for health promotion purposes enables improvement in performance of cognitive activities of institutionalized elderly persons, thus contributing to a better quality of life.
