O objetivo deste estudo foi avaliar o desempenho dos sistemas sensoriais e do controle postural de idosos diabéticos e investigar a relação entre as alterações destes sistemas e do controle postural desta população. Participaram deste estudo dez idosos diabéticos ativos (62±4,4 anos) (GDA), 10 diabéticos sedentários (65,5±7,4 anos) (GDS) e 10 idosos saudáveis ativos (63,2±4.5anos) (GCA) foram submetidos a avaliações sensoriais e de controle postural. As avaliações sensoriais foram compostas por avaliação somatossensorial (sensibilidade cutânea e sensibilidade ao movimento passivo). Para avaliar o controle postural foram analisadas medidas de oscilação corporal durante manutenção da postura ereta (em tandem stance e bipodal). Os resultados indicaram pior desempenho do GDS na avaliação do movimento passivo e de controle postural. Nas avaliações de controle postural, o GDS apresentou uma maior amplitude média de oscilação (AMO) (cm) nas condições de manutenção da postura ereta na posição tandem stance na direção médio-lateral. No teste de sensibilidade ao movimento passivo, o GDS precisou, em média, de um maior deslocamento angular para perceber o movimento das articulações do joelho e tornozelo. Estes resultados indicam, portanto, que as alterações estruturais e fisiológicas decorrentes do diabetes, resultam em piora do desempenho dos sistemas sensoriais e de controle postural. Além disso, a maior deterioração do sistema proprioceptivo em idosos diabéticos pode interferir negativamente no desempenho de controle postural dos mesmos. Desta forma, a atividade física minimiza a perda sensorial e ainda ajuda no controle postural dos diabéticos.

This paper analyzes the accessibility of the elderly population in relation to urban transportation in the city of Rio Claro - SP. After a study of the physiology, infrastructure, history and legislation of the city, there were collected and analyzed data obtained through semi-structured interviews with the elderly population that makes use of public transport with the aim of identifying the user's profile as well as their impressions and criticism of the service. The Department of Transport and Urban Mobility of Rio Claro provided general information related to public transport in the city. After all the survey, it can be seen that, although a significant portion of the elderly population make use of public transport, there are problems related to the structure of the city, which hinders the movement of buses, and the accessibility of the elderly, caused by physical characteristics of the vehicles, attitude of the motorists and aspects of public administration of the town. These data support the conclusion that there is often a disregard for the rights of the elderly and that it not only should as it can be corrected

The aim of this study was to investigate whether aerobic capacity (VO2max) would be modified by antihypertensive therapy in elderly and middle-age women after 12 weeks of exercise training. The volunteers were divided in two groups: normotensive (n=14) and hypertensive (n=14). Aerobic exercise was performed for 3 days/week, during 60 minutes, for 12 weeks with an intensity of 50-70% rest heart hate. Anthropometric parameters (weight and height), body fat index, % of fat mass, cardiopulmonary evaluation to calculated VO2max and a cardiovascular evaluation with blood pressure and rest heart hate were evaluated at baseline and after training program. At the end of study abdominal circumference and Borg scale were also evaluated. Our findings showed the aerobic program of 12 weeks was effective to reduce diastolic blood pressure in both groups. Systolic blood pressure was reduced only hypertensive group. No evidences were found the aerobic capacity was affected by hypertensive therapies. In conclusion, the aerobic program for 12 weeks was effective to reduce blood pressure and there was no influence of antihypertensive therapy on the aerobic capacity in this particular population.

The Alzheimer’s dementia represents a clinical condition inherent to many chronic and neurodegenerative diseases that are usually related to a decline in the cognitive and physical functions. The objective of this experimental design research was to analyze the effects of a regular and systemized physical activity program over the cognitive functions, balance and risk of falls of elderly with Alzheimer’s Dementia (DA). The sample was made of 16 elderly with DA, distributed in two groups: a) intervention group – GI (9 subjects that had participated in a program of physical activity, that consisted of 3 weekly sessions of 60 minutes each, in alternated days and with a duration of 6 months); b) control group – GC (7 subjects that did not participate in the program of physical activity). Both groups maintained the doctoral and pharmacological assistance routine. The subjects passed through two different evaluations (pre and post-intervention) the questionnaire (Mini-exam of Mental State for cognitive functions) and motor tests (Berg Functional Balance Scale – EEFB, Timed Up-and-Go (TUG) time (TUGs) and steps (TUGp) and the test of agility and dynamic balance (AGILEQ) of the American Alliance for Health, Physical Education Recreation and Dance for elderly). The obtained results were, respectively in the pre and post-intervention moments: a) AGILEQ (GI = 39,1 ± 10,2 and 38,4 ± 8,9 and GC = 45,6 ± 16,7 and 59,9 ± 22,0 seconds) with the statistically interaction significant (ANOVA two-way; F1,14 = 32,07; p=0,01) between groups and moments; b) TUGs (GI = 9,8 ± 2,5 and 9,5 ± 3,3 and GC = 10,6 ± 4,5 and 12,7 ± 7,3 seconds) the test UMann Whitney did not appoint any significant differences between the groups in the post-intervention moment, however the analyzes of Wilcoxon evidenced a ...(Complete abstract click electronic access below)

A fadiga muscular é definida como uma falha no sistema neuromuscular na capacidade de gerar uma força requerida ou esperada. Quanto maior a idade do indivíduo, maior é a probabilidade de chegar à fadiga, aumentando o risco de quedas. Dessa forma, a fadiga pode influenciar no andar dos indivíduos, causando prejuízos no controle postural e podendo causar lesões músculo-esqueléticas A partir dos estudos realizados, percebe-se que a fadiga muscular pode prejudicar o desempenho do andar, sendo ele adaptativo ou não. O objetivo do estudo foi analisar e comparar a influência da fadiga muscular sobre os parâmetros cinemáticos do andar livre e adaptativo entre adultos jovens e idosos. Participaram do estudo 20 indivíduos, distribuídos em dois grupos etários: Adulto Jovem - 20 a 40 anos; e Idoso - a partir de 60 anos. Os participantes realizaram o andar livre e adaptativo percorrendo uma distância retilínea de 8 metros sobre um carpete de borracha com 1,4m de largura. Foram realizadas 6 tentativas para cada condição experimental. Para a coleta dos dados cinemáticos dos ciclos do andar definidos foi utilizado um sistema tridimensional (3D) optoeletrônico de análise do movimento (OPTOTRAK Certus – 3D Motion Measurement System, NDI), com precisão de 0,1 mm, posicionado no plano frontal, face anterior, ao movimento do participante, com frequência de 100 Hz. A indução a fadiga será através da tarefa de sentar e levantar. Para a comparação entre os dois grupos foram analisados as seguintes variáveis espaciais e temporais do andar livre e adaptativo: comprimento de cada passo, largura de cada passo, velocidade média do andar, distância horizontal pé-obstáculo antes da ultrapassagem, distância horizontal depois do obstáculo e distância vertical péobstáculo. Estas variáveis foram analisadas durante o ciclo do andar antes e após fadiga muscular.

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.
