The aim of this study was to evaluate the changes in center of pressure (COP) movement in four time intervals (5, 10, 15 and 30 s) during a one-leg stance test performed by young and elderly adults. Twelve young adults (mean 20 years) and 12 elderly subjects (mean 68 years) participated in this study. The subjects performed three 30 s trials of an eyes open one-leg stance test on a force platform, in which the COP parameter was computed at four points in time from same original COP signal. Significant differences were found between the young and elderly adults (P< .007) only at the 10, 15 and 30 s intervals. For both groups, COP changes were significantly different between the 5 s time interval and other intervals (10, 15 and 30 s). In conclusion, these results pointed out that age-related difference in COP changes were time dependent. This suggests that the use of longer durations increases the possibility of distinguishing more subtle differences in postural strategy among different groups of subjects.

O objetivo deste estudo foi avaliar os aspectos do estilo de vida em jovens estudantes universitários da modalidade Ensino a Distância (EaD). Deste estudo transversal, participaram 104 universitários dos seguintes cursos: Pedagogia, Serviço Social e Licenciatura em Educação Física. Os instrumentos utilizados para coleta de dados foram três questionários: geral com a caracterização da população entrevistada, IPAQ para investigar o nível de atividade física habitual e o questionário estilo de vida fantástico. Para a análise estatística foi utilizado o software SPSS versão 20.0, para a descrição das variáveis pelo teste de Kruskal-Wallis para comparação entre os grupos. A média de idade foi de 30±9 anos, prevalecendo o sexo feminino com 63,4%. Em relação ao estilo de vida, 18% apresentaram-se na escala “regular”, 54% “bom”, 25% “muito bom” e 3% “excelente”. Observou-se que mais da metade dos universitários dos cursos de graduação do EaD foi classificada com um bom estilo de vida, porém os muito ativos apresentaram um pior escore. Estes resultados têm implicações para a caracterização do perfil universitário e permitem o desenvolvimento de programas de promoção da saúde específicos para disseminação e conscientização dos jovens adultos a adquirirem comportamentos saudáveis relacionados ao seu estilo de vidaPalavras-chave: Estilo de Vida.

To give support to Research three questionnaires were used :General Questionnaire which aims the characterization of the Interviewed population, the International Physical Activity Questionnaire (IPAQ) and a lifestyle questionnaire. The mean age was 30 ± 9 years, prevailing the female gender with 63.4%. Regarding the scale lifestyle, 18% were “regular”, 54% “good”, 25% “very good” and 3% “excellent”. This study analyzed through the questionnaires and statistical analysis program SPSS, that more than half of Undergraduate Distance Universiy courses, were classified asgood lifestyle, however, the very active ones had the worst scores.. These results have implications for the university profile characterization and allow the development of specific health promotion programs for the dissemination and awareness of Young Adults to acquire healthy behaviors concerning their lifestyle.Keywords: Life Style.

Introduction Dizziness can be characterized as a balance disorder that causes discomfort, leading to several functional limitations. Currently, vestibular rehabilitation has been highlighted as a possible treatment. Objective Analyze the effects of completing a vestibular rehabilitation treatment protocol on quality of life and postural balance in patients with vestibular complaints, as well as to compare these effects between the patients taking or not taking antivertigo drugs. Methods A nonrandomized controlled trial was performed with 20 patients previously diagnosed with vestibular diseases. Information regarding vertigo symptoms, quality of life as assessed through the Dizziness Handicap Inventory, visual analog scale of dizziness, and stabilometry using force platform was collected. Patients were treated for 12 weeks by a custom protocol. The sample was divided into two groups according to the use (medicated group, n = 9) or not (control group, n = 11) of antivertigo drugs. Results There was improvement in quality of life (p < 0.001) and intensity of dizziness (p = 0.003) with the intervention. An improvement of postural balance was observed through functional tests. However, no statistically significant difference was noted in stabilometry. When both groups were compared, no statistically significant differences between the variations of the variables analyzed were found in the re-evaluation session. Conclusion Quality of life and postural balance are improved with intervention. However, this improvement is not associated with pharmacologic treatment.

Introduction Studies have found that elderly patients with benign paroxysmal positional vertigo (BPPV) may present low levels of vitamin D (25 (OH) D), changes in bone mineral density, and diabetes mellitus (DM). Objective: To investigate the possible association between BPPV, bone mineral density, hypovitaminosis D, 25 (OH) D and DM. Methods The sample consisted of 109 elderly subjects. The BPPV was verified by a standardized questionnaire and the Dix-Hallpike maneuver. Blood samples were collected for the investigation of 25 (OH) D serum levels. The bone mineral density was evaluated by means of a densitometer. Diabetes mellitus verification was performed using a self-reported questionnaire. Results Of the 109 participants, 17 had BPPV. There was a statistically significant difference between BPPV and gender (p = 0.027, phi = 0.222), with female representing 88.2% of those with BPPV. In the group with BPPV, there was a statistically significant difference for the amount of vitamin D found (p = 0.001) and for age (p = 0.001). In the elderly group with DM and BPPV, a difference was found for the standard deviation of the femur (p = 0.022) with posthoc Dunn, identifying the difference between diabetics with and without BPPV (p = 0.047). Conclusion Although no association was found (25 (OH) D levels) with BPPV in the general population of this study, it was observed that there was an association with bone mineral density in the elderly group with DM and BPPV, and, in the group with BPPV, there was an association between the amount of vitamin D and age.
