Introduction: the improvements on the health area increased the brazilians life expectative. Because of it, more people becomes elder, passing through various common processes of aging, as the balance decrease. Resulting form this the risk of fall increase, and this has a negative impact on the quality of life. As more people become elder the institutionalization tax increase. Objectives: compare the balance and quality of life between institutionalized and non-institutionalized elders; correlate the Berg Balance Scale (BBS) with the Timed Up and Go test (TUG) and with the questionnaire “The Medical Outcome Study 36 – Item Short-Form Health Survey” (SF-36). Methods: were evaluated 20 elders, ten institutionalized (GI) and ten non-institutionalized (GNI). To the balance assessment were used the BBS and the TUG, the quality of life was evaluated using the SF-36. The signifi cance level was set to 5% (p<0,05). The GraphPad Prism 5# was used to analyze the data. To identify the distribution of the data was applied the Shapiro-Wilk test. In the comparison between groups, the normal distributed data were analyzed with the Unpaired Student t test. The non-normal distributed data were analyzed with the Mann-Whitney non-parametric test. The correlations were analyzed with the Pearson (normal data) and Spearman’s (non-normal data) tests. Results: the age average for each group was 72,8±8,36 years (GI) e 67,4±3,53 years (GNI). The GNI had a better performance than the GI in the BBS (*p=0,0017) as in the TUG (*p<0,0002). There wasn’t difference between the quality of life. There was correlation between EEB and TUG (-0,8907 for the GI and -0,7180 for the GNI) and between EEB and the functional capacity domain from the SF-36 (0,7657). Conclusion: the non-institutionalized elders presented best balance. It was found good correlation between TUG and BBS. In the studied sample, to be institutionalized didn’t infl uenced the quality of life.

Introduction: Biomechanical analysis of gait can be used effectively to identify changes in movement patterns and functional decline. Objective: To analyze the effect of dual task on gait spatio-temporal variables. Methods: The sample was made up of 32 subjects of both genders aged between 18 and 25 years. The test Timed Up and Go was performed under two conditions: original form and associated with a cognitive task (verbalize backwards the months of the year). We evaluated the total execution time, number of steps, cadence, time spent to lift, average speed and variability of the step time. Results: Significant changes were observed with the addition of the cognitive task in many gait spatio-temporal variables analyzed. Conclusion: The tests showed that the increase of cognitive tasks during walking may lead to changes in the performance of this task.

The effort test can be used to assess functional capacity, clinical hemodynamic and metabolic response at the effort, the risk of postoperative pulmonary complications and to assess the response of patients with lung diseases submitted to physiotherapy treatment. Among the stress tests we highlight the Six Minute Test Walk (6 MWT) and Stair Climbing Test (SCT), because they are easy to use and low cost. Especially the SCT is widely used in patients preoperatively. Objective: To compare the effects of six minute walk test and stair climbing test under the hemodynamic and oxygenation in healthy adults. Methods: We conducted a study with healthy subjects above 50 years. The fi rst performed was 6 MWT in quick step with encouragement, in a plan corridor of 30 meters, where the shade was determined the distance walked in 6 minutes, after 6 MWT was performed de SCT with encouragement, on a ladder in shade, consists of 44 steps, with 4 bids and bid by 11 steps, each step measured 16 cm in a total of 7.04 m of height, where the rise time was clocked. Before and after the two tests were measured respiratory rate, pulse, blood pressure and oxygen saturation. Results: We evaluated 21 patients with age 59.6 ± 5.4 years, 5 men and 16 women. The average distance covered on the 6MWT was 496.4 ± 102.2 meters and the average time in SCT 22.6 ± 5.4 seconds. The variables pulse, respiratory rate, systolic blood pressure and Borg scale presented a signifi - cant increase after the tests, however the variables oxygen saturation and diastolic blood pressure did not change signifi cantly. Conclusion: The variables pulse, respiratory rate, systolic blood pressure and Borg scale tests increased after six-minute walk test and stair climbing test but with greater signifi cance after the stair climbing test. Oxygen saturation and diastolic blood pressure did not change signifi cantly after the tests.

The aim of this study is to compare acoustic measures (frequency, duration and intensity) of the vowels /i, a, u/ in repetition and spontaneous tasks. Recordings of words produced by ten children with typical language development in both controlled and spontaneous tasks were selected from a database. The vowels were selected and edited into individual files in the software PRAAT. Acoustic measures related to formant frequency (F1 and F2), intensity and duration of vowels in both contexts were extracted. The values obtained were compared by means of T Tests. In general, the acoustic analysis showed no differences between the two contexts of speech production. The few differences found can be explained by the presence of focus and/or hesitation phenomena during the speech productions. It is possible to use data from spontaneous context to analyze the vowels acoustically, provided that both the phonetic context of the vowel occurrence and the syllable stress of the vocalic segment are considered.

Introduction:The regular practice of physical activity is being used as a therapeutic resource to the elderly population, with the objective of reduction of the losses provoked by the growing old process. The home place (urban or rural) is still little explored in literature about your infl uence in the physical capacity of the elderly people. Objective: The aim of this study was to value and compare the quality of life, motion and functional capacity between physically active and sedentary elderly people, residents in the urban and rural area. Methods: Sixty people with age above 60 years old were valued, 20 physically active residents in the urban area (66,5 ± 4,32 years), 20 sedentary residents in the urban area (68,8± 7,24 years), 10 physically active residents in the rural area (64,4±2,46 years) and 10 sedentary residents in the rural area (68±5,78 years). It was realized the evaluation of the fl exibility (previous fl exon of the trunk), mobility (timed up and go test), a six-minute walk test and answered a quality of life’s questionnaire SF-36. To compare the results obtained by the two groups was used the Kruskal-Wallis test, and the signifi cant presence of the test was performed post hoc Newman-Keuls. The level of signifi cance used in statistical analysis was 5% (p<0,05).Results: It was observed that the physically active elderly people obtaine better performance on the six-minutes walk test. It wasn’t found difference in the mobility among the groups. In relation to the quality of life, the elderly residents in the rural area, were better in the component Vitally. In relation to the fl exibility the elderly residents in the urban area obtained the best results. So, we can conclude that the practice of physical activity realized by the volunteers contributed to a better functional capacity, observed by the biggest distance gone through on the walk test. The rural home place positively infl uenced the vitality control, while the fl exibility was worse presented in these elderly people.

Overcurrents may endanger the whole electrical system and living beings, they are the result of short circuits and failures that can occur in electrical systems, no matter how well designed they are. Therefore it is important to predict these failures with analysis of electrical systems to make it possible to design appropriate protections, to ensure that those intervene properly and avoid technical and mainly human losses. However there is no standard for calculation of the short circuit currents, the main authors of the national literature about the subject suggest various methods, knowing the particularities among them provides quick and easy choice and proper application of them. To do so, a base case from an electrical system that presents a short circuit is chosen, which will be analyzed using the methods presented

Introdução: Até o presente momento, não existem observações com o intuito de comparar o andar (em terreno regular e durante a ultrapassagem de obstáculo) de pacientes com doença de Parkinson (DP) caidores e não caidores. O conhecimento mais detalhado das diferenças clínicas e locomotoras entre pacientes caidores e não caidores pode servir como ferramenta importante para o melhor delineamento de intervenções com o intuito de prevenir e/ou reduzir a ocorrência de quedas na DP. Objetivo: Comparar o quadro clínico e o comportamento locomotor durante o andar em terreno regular e a ultrapassagem de obstáculo de indivíduos com DP caidores e não caidores. Método: Participaram do estudo 36 indivíduos com diagnóstico de DP idiopática. Inicialmente, a ocorrência de quedas foi registrada durante quatro meses por meio de entrevista semanal (contato pessoal e telefônico). Estes dados foram utilizados para distribuir os indivíduos em dois grupos: caidores (n=12) e não caidores (n=24). Em seguida, os pacientes realizaram, em estado “on” do medicamento, a avaliação do quadro clínico e do comportamento locomotor. A avaliação clínica incluiu a aplicação da escala de Hoehn & Yahr (estágio da doença) e da subescala motora da Unified Parkinson’s Disease Rating Scale (comprometimento motor). A avaliação do andar consistiu em caminhar, em velocidade preferida, sobre uma passarela de oito metros de comprimento em condições com e sem obstáculo. Um sistema optoeletrônico para a análise do movimento (OPTOTRAK) foi utilizado para a coleta de dados do andar. As variáveis dependentes incluíram as pontuações nas escalas clínicas e os parâmetros espaciais e temporais do andar em terreno regular e da ultrapassagem de obstáculo. Resultados: Os pacientes caidores apresentaram menores valores do que os pacientes não caidores... (Resumo completo, clicar acesso eletrônico abaixo)

Electrical energy is present in the lives of all people and is extremely important that it be delivered to end users with plenty of quality, safety and low costs. The electric power substations are responsible for transmission and distribution of electricity generating sources to consumers, and with technological advances and the subsequent automation of same, the electricity began to be delivered with greater continuity and reliability. Protection systems in substations are largely responsible for making the electricity reaches the final consumer with quality, since their function is to prevent the spread of any type of failure occurred at any point of transmission to the load centers. These systems consist primarily by the current transformers and potential, by the protective relays and circuit breakers and switchgear. The processors send the necessary data to the relays and, if those detect any abnormality in the system, operate the opening command of the branch circuit breakers to isolate where the fault. Therefore, it is essential to better understand the operation of such equipment, as well as the overall system. This work aims to study the main substation equipment, current transformers and potential and, especially, protection relays, in order to obtain the advantages that automated systems can provide

The professional market for physical education and fitness demands for perfect and aesthetically beautiful bodies from its professionals, and the additional pressure of media, both add to the risk for body image dissatisfaction among these professional, increasing the risk for developing body image distortions and, ultimately, eating disorders. Body image dissatisfaction affects more women in their attempts for thin ideal. However, lately, because of social pressure for body aesthetical habits in both genders, men are faced with higher risk for distortions in body perception, leading to unhealthy eating habits and pathogenic exercise. With this in mind, the purpose of this study was to compare freshmen and senior physical education (PE) students from the State University of São Paulo (UNESP), as well as to make gender comparisons. Two groups comprise each, 46 freshmen PE students (23 females and 23 males), average age 18.7 ± 1.7 years; and 26 senior PE students (13 females and 13 males), average age 23 ± 1.9 years. Both groups filled out the questionnaires: Eating Attitudes Test/ EAT-26, Body Shape Questionnaire/ BSQ, Body Shape Questionnaire/ BSQ, and motivation state questionnaire/ LEA-RI. Results showed that the majority of participants wanted to change some aspect of their looks; women were more dissatisfied with their bodies than men; eating behavior scores were within the normal range for both groups. Finally, freshmen PE students are at a higher risk for body image distortion than senior PE students. We concluded that women, as well as younger individuals in general, are at higher risk for body image distortions. It is likely that experience in the further years of a physical education course has positive impact on body self image.

Introduction: The elderly population has increased, and the aging process is responsible for physical and metabolic changes in the body. For the elderly remain independent, with a better quality of life, preventing and treating diseases responsible for this increased of mortality should remain physically active. Objective: To investigate the influence of two types of exercise intervention on physical fitness and physical activity levels in older practitioners of Rio Claro-SP. Method: The study included 18 older adults with mean age 65.8 years (± 2.88) divided into two groups, Program in Physical Exercises Health Unit (PEFUS, n = 9) and Adapted Volleyball (n = 9). Classes of PEFUS were held twice a week lasting 60 min with strength, aerobic endurance, agility, coordination and balance exercises. Classes of Volleyball Adapted were performed 2 times per week lasting 120 minutes, divided into volleyball fundamental exercises and game. For evaluation of physical skills (strength, agility, coordination and flexibility), was performed the AAHPERD test battery. All participants were assessed at the baseline and after 3 months of interventions. The statistical analysis used was the repeated measures ANOVA, through the SPSS version 17.0 and significance level p <0.05. Result: After the interventions there was an increase of leisure time from 362.2 ± 214.9 min / week and 16.7 ± 28.3 min / week to 541.7 ± 137.2 and 44.4 ± 44.8 min / week to Adapted Volleyball and PEFUS, respectively. The variable coordination showed significant improvements after the interventions, decreasing from 12.1 ± 0.7 to 10.8 ± 0.5 sec for Volleyball Adapted and from 14.8 ± 0.9 to 12.1 ± 0, 9 sec for PEFUS (p <0.05). For the variable strength it was observed a group-moment interaction (p <0.05). Conclusion: The interventions showed positive results... (Complete abstract click electronic access below)
