Diabetes mellitus e esteatose hepática em ratos: efeitos de um protocolo de treinamento aeróbio

The present study aimed to analyze the effects of exercise performed at aerobic/anaerobic transition on non-alcoholic hepatic steatosis (NAHS) markers in diabetic rats. Adult (60 days) male Wistar rats were divided into 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (i.v. alloxan injection) (SD) and trained diabetic (TD). At the beginning of the experiment, all the animals were submitted to maximal lactate steady state test (MLSS) in order to identify the aerobic/anaerobic metabolic transition during swimming exercise. The trained groups were submitted to swimming, supporting overloads (% of body weight – b.w.) equivalent to MLSS intensity, 1h/day, 5 days/week, during 8 weeks. We analyzed: serum ALT, AST, albumin, glucose and free fat acids (FFA), body weight and total lipid concentrations in the liver. The diabetic groups showed higher (ANOVA two-way, p<0.05) serum glucose (SD=200% and TD= 150%) and weight loss (SD= 15.0% and TD= 8.5%) compared to controls and the SD showed higher glucose concentration and weight loss when compared to TD. The work load (% b.w.) equivalent to the MLSS was lower in TD (4.7%) than in TC (5.6%) group. The NAHS markers (U/L) did not show... (Complete abstract click electronic access below)

A interferência do estado de humor na melhora dos componentes da capacidade funcional em idosos

Mood States are feelings auto regulation deliver to individual better quality of life and healthy aging. The declines of the aging process can be minimized with the regular practice of physical activity and systematized. The objective of this study was to evaluate the effects of a dance program in mood states, depressive symptoms and functional capacity in elderly participants of PROFIT. METHOD: The sample was composed of 20 elderly people. The Training Group was formed by 15 elders who participated in a protocol of dance with duration of 1 hour, three times per week, for 12 weeks and the Control Group, composed of 5 elderly, did not attend any program of physical activity. The participants were evaluated by the List of States of Mind Reduced and Illustrated, Geriatric Depression Scale and the battery of tests of AAHPERD. For the mood states was used non-parametric analysis, according to the technique of Binomial Analysis. To compare the components of functional capacity between the groups was used analysis of variance for repeated measures two-way ANOVA and the level of significance was set at 5 %. RESULTS: The functional components remained favorable, highlighting Agility (pre = 21.03 ± 1.64 sec./ post = 18.63 ± 2.26 sec.) And aerobic endurance (pre = 495.94 ± 46.48 sec. / post = 448.01 ± 12.27 sec.). In the comparison between positive and negative functional levels and mood states showed no relationship between these variables, dealing with different aspects and has influence one another. The state post-dancing sessions mood in GT were more positive even for elderly patients with depressive symptoms even unproven statistically, depressive symptoms were maintained or reduced mostly. CONCLUSION: The dance practice maintains the functionality of components; modifies mood states to positive levels and reduces or prevents the onset of depressive symptoms and complications in elderly

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Interferência de aulas de ginástica nos estados de ânimo dos praticantes

Atualmente pode-se observar a importância da atividade física na vida diária da população promovendo, além dos benefícios físicos, benefícios sociais e psicológicos. Nesse sentido a atividade física, mais especificamente a ginástica sistematizada (Body Systems), hoje em dia adepta a boa parcela da população, se tornou importante para seus praticantes, visando à prevenção de lesões, normalizando as funções corporais e proporcionando descontração e socialização. O objetivo geral deste trabalho foi analisar a interferência das aulas de ginástica sistematizadas nos estados de ânimo de seus participantes. Participaram do estudo 35 indivíduos, de ambos os gêneros, estudantes do curso de Educação Física da UNESP de Rio Claro, SP, com disponibilidade para executar as intervenções semanais e que pudessem responder as listas de estados de animo (LEA-RI) antes e após a aula. Neste estudo foram analisados três estilos diferentes de ginástica, a ginástica com pesos, BODYPUMP, a ginástica cardiorrespiratória, BODYATTACK e a ginástica de condicionamento postural que provém de técnicas como o Yoga e o Pilates, o BODYBALANCE. Com base na analise binomial foi possível chegar a alguns resultados significativos quanto à interferência das aulas de ginástica nos estados de animo de seus praticantes. Ao praticar a aula de BODYBALANCE as pessoas se sentiram mais felizes, mais leves e menos desagradáveis correspondendo a proposta da aula. Com o BODYPUMP as pessoas se sentiram mais pesadas e na aula de BODYATTACK sentiram-se além de mais pesadas, menos tímidas, ou melhor, mais descontraídas. Isso mostra que as aulas de ginastica podem ser utilizadas não apenas para benefícios físicos, mas também com objetivos de direcionar para a alteração de determinados aspectos psicológicos

Treinamento de força unilateral: efeitos sobre a taxa de desenvolvimento de força do membro contralateral

The aim of this study was to analyze the effects of unilateral isokinetic strength training at high speed (180°.s-1) of the dominant leg on the rate of force development (RFD) of the contralateral limb. The study included 18 male individuals, apparently healthy, with an average of 23 years, and without regular practice of physical activities. The subjects were divided randomly into two groups: control group (GC) and isokinetic group (GISOC). Assessments were made of the values of peak isometric torque (PT isom) and RFD of both lower limbs in the pre-training. So, the GISOC underwent an isokinetic strength training with high speed (180°.s-1) for 6 weeks, with the dominant leg only and then reassessed. It was found that there was no significant improvement in value of PT isom (p> 0.05), and the RFD for the dominant limb had a significant improvement (p< 0.05) compared to the pre-training and that there was no transfer of values to the contralateral side (p> 0.05). It can be concluded that the isokinetic training at high speed was not enough for significant cross education

Análise cinemática e cinética do salto vertical de crianças com transtorno do desenvolvimento da coordenação (TDC)

Due to motor difficulties, children with developmental coordination disorder (DCD) doesn't feel motivated to do physical activities, sometimes resulting in a decline of their physical fitness, but it isn't really known for sure the reasons that induct children with DCD to low performances in physical fitness tests, because a lot of tasks that are part of the battery of tests of physical performance are complex in the coordination and/or motor control point of view, like the vertical jump for example. Therefore, the objective of this study was to investigate the factors that induct children with DCD to low performances in physical fitness tests, especially in the vertical jump task. For that, cinematic (duration of the eccentrical phase, duration of the concentrical phase, shift of the mass center and velocity of the mass center), kinetic (potency peak and force peak) and vertical jump performance analysis in two conditions (with the use of arms and without it) were realized in a force platform. The results indicated that children with DCD show a lower performance compared to their peers with typical development (TD), due to a lower potency production

Square stepping exercise: uma revisão

Many studies inform that with aging process there’s a drop, not only in the cognitive functions, but also in the functional fitness. This drop can damage the old people’s daily activities, making them lose their independence. These declines can be softened with the practice of physical exercises. So, the aim of this study is to develop a systematic review in the literature which is the quantity of lectures done using the Square Stepping Exercise, we use a follow keyword “Square Stepping Exercise”. We performed a search in the following databases: PUBMED, Portal de Periódicos CAPES, Google Acadêmico e Catálogo Athena (acervo da Biblioteca de todos os campus da UNESP). Those procedures were complemented for manual searches in the references of the found lectures, like the access to the curriculum vitae, plataforma Lattes. There were analyzed articles, in Portuguese and English. Language were selected 11 studies (2 monografies, 1 masters lecture, 1 experience relatorie, 1 book chapter and 6 articles). The references found had improvement in motor and cognitive aspects. With this review, it was concluded that the SSE showed itself as a useful method to get better and/or maintain the analyzed aspects. It’s also necessary new studies with different populations, tips of analyse, periods of time and other aspects

Terapia do diabetes mellitus em cães

Diabetes Mellitus is caracterized by a disturbance on endocrine pâncreas with reduction in serum levels of insulin. The deficiency or absence of insulin promotes alterations in the metabolism of carbohydrates, lipidis and proteins. The most common clinical signs of disease are polyuria, polydipsia, polyphagia and loses of weight. The diagnosis is made based on clinical symptoms, with laboratory confirmation through persistent hyperglycemia on fasting and glycosuria. Treatment includes insulin therapy, diet, exercise and oral hypoglycemic agents in an attempt to reverse the catabolic effects associated with deficiency or antagonism of insulin and restore normal homeostasis of the metabolism of proteins, lipids and carbohydrates

Efeitos do treinamento com pesos nas atividades de vida diária básicas e instrumentais de pacientes com doença de Alzheimer

The Alzheimer's disease (AD) is a neurodegenerative and progressive disease, mostly seen in elderly people, characterized by memory loss. This commitment leads causes deficits in functional capacity, compromising the individual in execution of activities of daily living, like dressing and bathing. This study, with a longitudinal character, aimed analyze the effects of a protocol of weights training (WT) in global cognitive status and realization of activities of daily living (ADL´s) basic and instrumental in AD patients, comparing the effects of four months of WT in the performance of ADL´s in global cognitive status. And also aimed to verify the possible relations between ADL's and global cognitive status of patients before and after the experimental period. The study included 24 patients with clinical diagnosis of AD, divided into two groups: a) training group (TG) consisted of 13 patients who underwent a protocol of WT b) Social Gathering Group (SCG) consists of 11 patients participating in a protocol of social gathering not systematized with activities of reading, writing and walking. Both protocols lasted four months, being developed in three non-consecutive weekly sessions, lasting 60 minutes each. To quantify global cognitive status and the basic and instrumental ADLs were used, respectively, the Mini-Mental State Examination and the Self Perception of Performance in Activities of Daily Living, along with the battery of tests of Activities of Daily Life of Andreotti and Okuma (1999). To analyze the results where complied the nature of the data, using analysis of variance for repeated measures ANOVA two-way and Pearson correlation for continuous data and tests of U Mann Whitney, Wilcoxon and Spearman correlation for non-continuous data, assuming level significance of 5% for all analysis. After analysis it´s possible... (Complete abstract click electronic access below)

Validação de uma escala colorida de esforço percebido para adultas jovens e idosas em caminhada na esteira

The perceived exertion has been used for the intensity control and exercise prescription. Among the various scales that estimate the perceived exertion, the Borg’s RPE scale is one of the best known. However, for populations with low levels of schooling or with visual difficulties such as the elderly, the application of these scales becomes more difficult. In previous studies, a color scale of perceived exertion was developed to aim for assistance in application of the scale and interpretation of perceived exertion. This scale showed high correlation with the Borg’s scale and proved to be valid to estimate the perceived exertion. Thereby, the aim of this study was to assess the validity of the color scale of perceived exertion to measure the perceived exertion in adult women of different ages. Participated in the study 12 young adult women with age of 21,7 ± 1,5 years old, and 10 elderly women with age of 60,3 ± 3,5 years old. The participants were submitted to an incremental exercise of treadmill walking with stages of 2 minutes duration. The inicial load was 5,5 km/h and inclination of 6% for young women and 2% for elderly women, both with 2% increments at each stage completed, without changing the speed. Heart rate and oxygen comsuption responses were determined at the 30 finals seconds of each stage. At the 60 finals seconds of each stage participants indicated the perceived exertion for the overall body, for the legs and for the chest, primarily in the color scale and following in the tradicional Borg’s scale. The analysis of variance for repeated measures was used to assess the effect of different loads on the perceived exertion and physiological responses. The correlations betwen physiological variables, color scale and Borg’s scale were analyzed in group and individually. In all analysis the significance...(Complete abstract click electronic access below)

Efeito da plataforma vibratória na recuperação da densidade óssea de ratas ovariectomizadas

As mudanças demográficas decorrentes do envelhecimento populacional têm contribuído substancialmente para o aumento de doenças crônicas não transmissíveis relacionadas à idade, dentre elas está a osteoporose, considerada um dos principais problemas de saúde pública, por sua prevalência crescente e pela associação a fraturas em diversas áreas do corpo, com graves repercussões clínicas e sociais. Com isso vem se buscando cada vez mais alternativas de exercício físico válidas para o combate e prevenção a estas doenças ósseas. Como possível alternativa têm se estudado os efeitos e benefícios dos treinamentos realizados em Plataformas Vibratórias, equipamento que através de baixa amplitude e alta freqüência pode vir a influenciar positivamente nas capacidades físicas. Portanto, devido à escassez de informações acerca dos efeitos do exercício na plataforma vibratória sobre a microarquitetura dos ossos em indivíduos idosos e já acometidos pela osteoporose, o objetivo deste estudo foi, com um modelo animal, descrever através de imagens de Microscopia Eletrônica de Varredura (MEV), a reação do tecido ósseo de ratas idosas ovariectomizadas ao exercício em Plataforma Vibratória. Para execução deste estudo foram utilizadas 20 ratas Wistar (Rattus Norvegicus Albinus Wistar), separadas em 4 grupos: Sedentário Controle (S), Sedentário Ovariectomizado (SO), Treinado Controle (T) e Treinado Ovariectomizado (TO). Como protocolo de treinamento a plataforma vibratória foi regulada com freqüência de 35 Hz e amplitude baixa (1 a 2 mm) e consistiu de uma fase de adaptação ao exercício e à vibração e após este período uma fase de treinamento. Para análise a região do osso selecionada foi o terço proximal da diáfise do fêmur. Como resultado, obtivemos que para o grupo SO a indução à osteoporose foi positiva quando comparada ao grupo S, que ...(Resumo completo, clicar acesso eletrônico abaixo)

Efeito do treinamento com pesos nos distúrbios do sono e na qualidade de vida de pacientes com demência de Alzheimer

The Alzheimer's dementia (AD) is the most prevalent form of dementia in the elderly. Among the harmful changes arising from the DA, there may be sleep disturbance and impaired quality of life. Physical activity is an important non-pharmacological feature that would provide positive effects for the treatment of disease. However, there are still few studies that clarify the effects of resistance training in this population. Thus, the present study has as objective analyzes the effects of the resistance training in sleep disturbance and quality of life of patients with AD. Participated in this study 22 patients with clinical diagnosis of AD divided into two groups: Training Group (TG) and Social Interaction Group (SIG). The subjects of TG underwent a resistance training protocol, appropriate to the individual conditions, during three days no consecutive in the week, with duration of 60 minutes each session, for 16 weeks. The SIG won't participate in any systematized physical activity, but they realized other activities, such as reading, poetry, hiking and painting, among others. This protocol also was realized three times in week for 16 weeks, with duration of 60 minutes each session. Both groups were assessed at the beginning of the program and after 16 weeks. For the assessment of sleep disturbance was used the Mini Sleep Questionnaire and to assess of quality of life was used the Scale for Assessment of Quality of Life in Alzheimer's disease (QL), versions: patient, caregiver, family and the final score. Due to the scalar nature of the data and small sample, all variables were analyzed by nonparametric statistics. The U-Mann Whitney test, Wilcoxon test and Spearman correlation test was used, except for the Modified Baecke... (Complete abstract click electronic access below)
