Influência do fortalecimento muscular na independência funcional de indivíduos parkinsonianos

Introduction: Parkinson’s disease is a chronic disease of the nervous system that leads to a clinical picture of resting tremor, bradykinesia, muscular rigidity and postural instability. These symptoms, in turn, directly influence the functional independence of the individual. Objective: To analyze the influence of muscle strengthening on functional independence of individuals with Parkinson’s disease. Method: A total of ten subjects of both genders participated in this study. We evaluated the functional independence, strength of lower limbs, grip strength testing and 1 repetition maximum. After the evaluation was performed muscle building program for 12 weeks. Results: There was improvement of functional independence (p = 0.007) and lower limb strength (p = 0.01), as well as an increase in grip strength, both of the dominant hand (p = 0.007) and the non-dominant one (p = 0.02). Conclusion: The muscle strength improved the functional independence of individuals with PD.

O exercício resistido na mobilidade, flexibilidade, força muscular e equilíbrio de idosos

Introduction: Some losses resulting from aging can be minimized with the practice of resistive exercises. Objective: To analyze the effects of resistive exercises on flexibility, mobility, muscle strength and balance in the elderly. Method: Twenty elderly individuals were divided between an activity group (AG, n=10; 66.1±6.35 years) and a control group (CG, n=10; 65.4±7.54 years). Mobility, flexibility, muscle strength and balance were evaluated. The AG participated in the training for 13 weeks (one-hour sessions, twice a week). The Wilcoxon non-parametric test (intra-group analysis) was used to analyze the data. A significance level of 5% (p<0.05) was adopted. Results: After training, the AG presented better mobility, lower limb muscle strength, and balance, but no difference in flexibility. Conclusion: The present study allows us to conclude that resistive exercises were able to improve mobility, lower limb muscle strength and balance in elderly individuals.

Existe correlação entre força muscular com o teste de caminhada de seis minutos em idosos institucionalizados?

The six-minute walking test can be affected by several variables, among them, the respiratory and peripheral muscle strength. The objective of this study was to correlate the respiratory muscle strength (maximum inspiratory pressure – MIP; and maximum expiratory pressure – MEP) and the hand grip test (HGT)with the six minute walking test distance in institutionalized elderly. It was included in this study 9 institutionalized elderly with age over 70 years old, both gender, evaluated by means of manometer, dynamometry and six minute walking test. The data were correlated by using the Pearson’s correlation test and the Spearman correlation test. From the evaluated elderly, it was four men and five women, with mean age: 78.8±7.3 years old, MIP: 75.7±33.6 cmH2O, MEP: 62.4±25.0 cmH2O, HGT: 20.4±6.2 kgf (right member) and 20.7±6.8 kgf (left member) and the distance on six minute walking test: 238.5±99.0 meters. There was correlation between expiratory strength and hand grip of both members with the distance on the six minute walking test. It is possible to conclude that there are correlation between expiratory muscle strength with the hand grip test and the functional capacity in institucionalized elderly.

Efeitos do método pilates na força muscular respiratória

Uma das técnicas mais modernas utilizada na fisioterapia e em outras áreas da saúde é o método Pilates. Esse método utiliza de forma intensa a respiração, e pode assim alterar a força muscular respiratória. O objetivo do presente estudo é verificar se há influência da prática do Método Pilates na força muscular respiratória em adultos e comparar com um grupo controle. Foram selecionados 20 indivíduos, divididos em dois grupos (controle e experimental), com idades de 20 a 30 anos, não fumantes, sedentários e que relatem não apresentar qualquer doença sistêmica ou metabólica. Todos os indivíduos foram submetidos à avaliação da pressão inspiratória máxima (Pimáx) e pressão expiratória máxima (Pemáx) com aparelho manovacuômetro (Comercial Médica). A seguir, foi aplicado um protocolo de 10 sessões de pilates para o grupo experimental, constituído dos seguintes exercícios do método: Spine stretch, Spine stretch forward, Saw, Mermaid, Swan, Breast stroke preparation, Abdominal curls, Roll up, Bridge, Single leg circles, Leg up and down, The hundred, Criss cross, Single leg stretch, Double leg stretch, Aductors, Shell. O grupo controle permaneceu sem atividade física. Após cinco semanas os dois grupos foram reavaliados. Os resultados encontrados demonstraram um incremento na força muscular respiratória do grupo experimental. Após a aplicação do teste Anova (p<0,05) foi encontrada diferença estatisticamente significante somente na comparação da Pimax inicial e final do grupo experimental (p = 0,028).

Spirulina e exercício físico no controle do metabolismo muscular da glicose em ratos diabéticos

O Diabetes mellitus é um problema de saúde pública mundial. Tal doença é caracterizada pela redução da secreção (Diabetes mellitus tipo1) ou da ação (Diabetes mellitus tipo2) da insulina, acarretando hiperglicemia, além de alterações no metabolismo das proteínas e dos lipídeos. As consequências para o organismo são variadas, incluindo hipertensão, nefropatias, retinopatias e cardiopatias. Atualmente existe grande interesse nas ervas medicinais, como hipoglicemiantes naturais, entre elas, a spirulina. A spirulina parece ser boa fonte protéica para a alimentação, tem boa aceitação e não apresenta efeitos tóxicos aparentes. Além disso, ela pode exercer efeitos benéficos no tratamento de algumas doenças como câncer, desnutrição, obesidade, hipercolesterolemia, hipertensão arterial, diabetes mellitus,entre outras. Tendo em vista a grande possibilidade utilizar a spirulina na dieta, o presente estudo visa analisar o metabolismo muscular da glicose em ratos diabéticos. Não foram encontradas diferenças significativas entre os grupos nas variáveis metabólicas estudadas

Órtese de tornozelo: efeito sobre a razão de pico torque muscular eversor excêntrico/inversor concêntrico do tornozelo durante simulação do basquetebol

The ankle sprains represent the most common injuries in sports and basketball. In this sense, the use of ankle bracing and strength capacity analysis of the ankle evertor and invertor muscles, have been suggested as preventive measures and important tools for identifying risk factors associated with ankle sprains. However, questions still persist as to effect of the use ankle bracing on biomechanical variables related to the stability of the ankle. For this reason, this study aims to analyze the effect of the use of ankle bracing on peak torque (PT) of ankle evertor and invertor muscles and on eccentric evertor/concentric invertor torque ratio (EVEECC/INVCON), during the basketball match-play simulation. Ten healthy college basketball players, without mechanics or functional ankle instability performed a laboratory-based protocol representative of work rates observed during basketball match-play, in two different situations, with and without use of ankle bracing. The test was composed of a succession of intermittent physical effort equally distributed in four periods of 10 minutes each, considering the mechanical and physiological demands of a basketball match-play. Prior to the start of the trial (Evaluation 1) and after 2° (Evaluation 2) and 4° (Evaluation 3) periods, the subjects performed five maximal isokinetic concentric and eccentric contractions of ankle invertor and evertor muscles, separated by two minutes rest, at 60 °/s and 120 °/s. After testing for normality of data distribution with the Shapiro-Wilk test, was used the ANOVA repeated measures for two factors and post-hoc Bonferroni test for comparison of variables between assessments. Was adopted p < 0.05. There was no significant difference for PT and EVEECC/INVCON torque ratio between assessments. There was a decrease in PT EVEECC at 60º/s and 120º/s for the ...(Complete abstract click electronic access below)
