Revisão sistemática do efeito do envelhecimento no andar livre e adaptativo

Aging seems to impair the walking. However, it is not clear the effects of aging on walking. The aim of this study was to determine changes in kinematic, kinetic and electromyographic parameters of the free and adaptive gait, in preferred velocity, caused by aging. The initial search strategy was performed to identify all articles that examined the free and adaptive gait. The electronic databases analyzed were: MEDLINE, PubMed, EMBASE, CINAHL, Sports Discus, DARE, PsychInfo, ERIC, AusportMed, AMI, Cochrane and PEDro. Twenty-three articles were reviewed in full. Elderly are slower, with shorter step length and longer double support duration than young adults during free and adaptive gait. Even, they showed higher muscular demands, with redistribution of joint power and torque and decreased force in the propulsion and absorption phases. It was concluded that elderly present altered kinematic, kinetic and electromyographic parameters of free and adaptive gait compared to young adults.

Projeto Memória e Envelhecimento: capacitando profissionais e aprimorando aspectos cognitivos em idosos institucionalizados

The increase in elderly population is a worldwide phenomenon and has different consequences not only in terms of health, but also in economic terms. One of those consequences is the institutionalization. The project, running in two elderly care institutions (hereafter IRLPi) located in Marília – SP aims to: a) Train multidisciplinary team to work in IRLPi’s; b) Develop and promote activities that improve life quality focusing on the preservation of mental health; c) study general and mental health conditions of patients under elderly care institution programs. The project was implemented in three phases: a) data collection and elaboration of plan of activities; b) Application of activities; and c) assessment/ analysis of results. Regarding Phase 1, data were collected from 3 forms, through which it was possible to verify: Institutional Data; Social Data and General Health. The data related to health were collected from the medication of continuous use. All data were launched into the database (Access) and subjected to the descriptive statistical analysis. Data related to mental health were confirmed from the application of clinical trials (Geriatric Depression Scale - EGD, and MMSE-T).

Memória, envelhecimento e qualidade de vida: a perspectiva da psicologia cognitiva

The concern with aging has increased in recent decades throughout the world, before the gradual increase in life expectancy of the population. Researchers have been developing a diverse in nature, in order to subsidize the activities of professionals in the field of Gerontology to promote autonomy, preservation of cognitive functions and thus contribute to healthy aging. This article presents a review of the literature on memory and aging from the perspective of cognitive psychology. The bibliography contains studies focusing on different subjects, in this sense. A significant number of works have been undertaken in order to investigate mechanisms and benefits of training on memory in healthy elderly and / or cognitive improvement. A concept that deserves attention in such studies is the study of aspects of meta-memory. However, there are still relatively few controlled studies on the subject.

Desempenho fisiológico e superação de dormência em sementes de Brachiaria brizantha submetidas a tratamento químico e envelhecimento artificial

The use of seeds of B. brizantha has increased, however, the physiological quality of seeds available to the producer is still a limiting factor for a good performance culture. The objective of this study was to evaluate the effects caused by chemical scarification, different periods of aging and priming on physiological quality and overcoming seed dormancy B. brizantha cv. MG-5 Victory. The seeds were subjected to chemical scarification-H2SO4 ( presence and absence), artificial aging periods ( zero, 24, 48, 72, 96, 120, 144 and 168 hours) at 41 degrees C and priming using the 0,2 KNO3 % ( presence and absence) for two hours at 25 degrees C, creating a completely randomized design in factorial 2x8x2, with four repetitions. The seeds were evaluated by testing germination and vigor. Chemical scarification is an effective method for breaking dormancy, but decreases the physiological seed. Overcoming seed dormancy B. brizantha occurs with the use of artificial aging for non-scarified and scarified seeds. Priming generally has no effect on the physiological quality and overcoming seed dormancy B. brizantha, however, it provides less loss of cellular constituents.

Estudo do envelhecimento da liga AA 7075 encruada

Aluminum alloys are widely used in industry, because they combine different mechanical properties according to the alloying elements used in addition to thermal and mechanical treatments performed, resulting in materials with good weight/resistance relation. The 7XXX series alloys are worked heat treatable alloys commonly used in the aerospace industry, especially due to their high mechanical properties obtained after aging heat treatment, which increases the interest around 7075 alloy. Some studies with alloys which can be aged show that it is possible that cold word processes affect the results of aging. Thus, this study was intended to verify the influence of the aging process of AA 7075 alloy. There were three routes of aging with specimens previously treated thermally. In the first route T6 treatment was performed with a annealed specimen and other in solid solution. The second was the natural aging in a annealed specimen. In the last route was done aging by steps with a annealed specimen and other in solid solution with the intention to reduce the effects of natural aging. The results show that the routes 1 and 3 had similar hardness for all the samples, showing that the validity of Route 3 as an alternative and also the hardening did not affect the hardness at the end of the process, significantly reducing the time required for the highest hardness. Finally, natural aging was less effective in increasing hardness

Comportamento de indivíduos com doença de Parkinson no levantar da cadeira e no início da marcha: relações com o envelhecimento

Large motor dysfunctions are observed in older adults with the age advance. Parkinson’s disease (PD) patients have motor deficits to perform daily living activities. To raise from a chair, a daily task necessary to live independently, requires both large muscle recruitment and large joint range of motion to achieve the vertical position safely. Normally, we initiate gait after raise from a chair. The aim of this study was to analyze the PD patients’ behavior when rising from a chair and initiating gait and to compare it according to the age advance. In order to do that, 23 PD patients (66.61±7.64 years old) were distributed in three age groups: Young group, between 51 and 60 years of age (n=7); intermediary group, between 61 and 70 years of age (n=7); and elderly group, over 70 years of age (n=9). There were no statistical differences among groups either for the disease evolution stage or for it compromising. The task was to stand from a chair and to initiate gait forward in three attempts. The dependent variables were: spatial and temporal (first step length and duration, and stride length, duration and velocity) and angular (flexion and extension of head, shoulder, hip, knee, and ankle). The motion of standing from a chair was divided in two phases. The data was statistically treated by means of Analyses of Variance with group as the only factor. The Scheffé’s post hoc test was used to localize differences among groups and the significance level was adjusted to p≤0.017. There were statistical differences for stride...(Complete abstract click electronic access below)
