La altura del salto se sigue usando ampliamente para predecir la potencia en seres humanos. El progreso individual, a menudo, se monitorea usando una estimación de la potencia, pero las ecuaciones de predicción se basan en datos grupales. El estudio pretende demostrar que la altura del salto vertical (VJP) y la potencia mecánica tienen una pobre correlación, particularmente en un mismo individuo. Se presentan dos experimentos; primero, 52 estudiantes universitarios físicamente activos ejecutaron cinco saltos verticales máximos cada uno; segundo, tres participantes masculinos ejecutaron 50 saltos máximos cada uno. Los participantes descansaron 1 minuto entre saltos. VJP se calculó a partir de los datos cinemáticos como posición más alta del centro de masa corporal (BCOM) menos BCOM de pie; la potencia pico (PEAKPWR) se calculó a partir de la fuerza vertical de reacción registrada por una plataforma de fuerza y la potencia promedio (MEANPWR) durante la propulsión a partir del cambio en la energía potencial del BCOM. Se realizaron análisis de regresión usando puntajes estandarizados de VJP como la variable predictora y puntajes estandarizados de potencia como las variables resultantes, con la expectativa de obtener una función de identidad y = x (intercepto = 0, pendiente = 1) y R2 = 1. En el experimento 1, el modelo para zPEAKPWR arrojó R2 = 0.9707 (p < .0001) pero la pendiente (0.3452) ≠ 1 (p = 8.7x10-15). El modelo para zMEANPWR dio R2 = 0.9239 (p < .0001); sin embargo, la pendiente (0.4257) ≠ 1 (p = 1.15x10-5). En el experimento 2, todos los modelos individuales para zPEAKPWR y zMEANPWR arrojaron asociaciones débiles (R2≤ 0.21) y pendientes ≠ 1 (p≤ .001). En conclusión, el análisis de regresión para individuos y aun para grupos confirma que la altura de salto vertical es un pobre predictor de la potencia mecánica.

Objetivo: Investigar relações entre lesões na articulação glenoumeral e a cinemática do movimento barra fixa executado por praticantes da modalidade CrossFit. Materiais e Métodos: 7 praticantes avançados na modalidade executaram três repetições do movimento de barra fixa e foram filmados para a coleta de dados a respeito dos ângulos articulares da articulação glenoumeral. A análise cinemática foi realizada com o software Kinovea®. Resultados: Os voluntários apresentaram um ângulo da articulação glenoumeral acima de 90° na fase média - momento em que o ombro se encontra em elevação e abdução -, posição de alto risco de lesão por impacto subacromial em razão do grau elevado e a uma maior tendência a erros técnicos por fadiga ou desequilíbrios musculares, acarretando à sobrecarga na articulação do ombro. As mulheres atingiram ângulos menores de adução em comparação com os homens e apresentaram um encolhimento dos ombros, ambas ações compensatórias e propensas a lesões por impacto devido a uma maior ativação do trapézio superior e menor ativação do serrátil anterior, aumento da inclinação anterior da escápula e predisposição a uma rotação interna do úmero. Conclusão: Os resultados indicam um potencial de lesão na articulação glenoumeral no exercício barra através das técnicas do CrossFit, no qual deve-se realizar um alto número de repetições. Deste modo faz-se importante um planejamento adequado do volume de treinamento no CrossFit e de exercícios focados no controle do movimento, fortalecimento, reparação de possíveis desequilíbrios musculares e mobilidade dos ombros.

Introdução: Estudos sobre análise quantitativa da deglutição são de extrema importância, porém, ainda não estão definidos na literatura os parâmetros de normalidade e existem diferentes escalas de avaliação dos fenômenos biomecânicos desta função. Investigar as diferentes definições das variáveis quantitativas temporais pode contribuir para a melhor definição e determinação dos tempos e marcadores fisiológicos da deglutição para diferentes populações. Objetivo: Analisar, de forma quantitativa, a fase oral da deglutição de indivíduos com Doença Pulmonar Obstrutiva Crônica (DPOC). Método: Foram incluídos 25 indivíduos adultos clinicamente estáveis com DPOC, média de idade de 65,7±8,9, ambos os sexos. A análise foi feita a partir da Videofluoroscopia da deglutição (VFD). Três juízes cegados e treinados realizaram a análise da variável quantitativa temporal Tempo de Trânsito Oral seguindo a classificação proposta por dois diferentes autores (TTO e TTOT), bem como das variáveis visuoperceptuais. O estado de conservação dentaria também foi avaliado. Resultados: Observou-se TTO de 2,09s para líquido e 1,61s para pastoso, e TTOT de 2,34s e 1,84s para líquido e pastoso, respectivamente. Os TTO estão alterados e maiores à medida que a gravidade da DPOC aumenta. Para ambas as consistências, o local do disparo da deglutição ocorreu em regiões anatômicas superiores. Houve ausência de escape posterior precoce e resíduo faríngeo na maioria dos pacientes. Conclusão: Observou-se alteraçao na fase oral da deglutição em indivíduos com DPOC os quais apresentaram TTO aumentado e mau estado de conservacao dentaria.

La poliomielitis es una enfermedad que puede provocar secuelas irreversibles, generando pérdida de fuerza muscular, parálisis e hiporreflexia, entre otras. Hoy en día las infecciones por poliovirus están controladas, pero se siguen tratando personas con secuelas que pueden ver afectada su calidad de vida y funciones cotidianas, tales como la marcha. Habiendo agotado las opciones de tratamiento conservadoras, la artroplastia total de rodilla (ATR) es una de las intervenciones quirúrgicas más habituales cuando las secuelas afectan la morfología y funcionalidad de dicha articulación. El objetivo del estudio es realizar un análisis instrumentado de la marcha de un paciente con secuelas de poliomielitis y una ATR, con el fin de definir las mejores estrategias de rehabilitación y mejorar la recuperación de la máxima funcionalidad. El estudio se realizó en un Laboratorio de Análisis de Movimiento con 8 cámaras, mediante la colocación de marcadores reflectivos en el cuerpo del paciente. Los resultados muestran alteraciones del patrón de marcha en todas las articulaciones de las extremidades inferiores y en cada uno de los planos anatómicos, siendo la más relevante la rotación interna de la articulación de la cadera derecha y una flexión fija en 9 ° de la articulación de la rodilla ipsilateral, durante la primera mitad del ciclo de marcha. El análisis sugiere que el paciente adopta estrategias que favorecen la activación del tensor de la fascia lata como flexor de cadera y estabilizador de la articulación de la rodilla en la máxima extensión disponible (9 ° de flexión), en sustitución del músculo cuádriceps, debilitado debido a las secuelas de la poliomielitis.

Parkinson's disease (PD) is a chronic, idiopathic, degenerative disease that decline postural control and balance. Whole-body vibration (WBV) has been studied to assist in the treatment of disorders caused by PD, since it can affect the muscular performance of the elderly.The aim was to verify the acute influence of WBV on the static and dynamic balance of individuals with PD. Fifteen individuals with idiopathic PD were divided into groups: seven in the placebo group (f = 1 Hz) and eight in the vibration group (f = 30 Hz). After anamnesis, the volunteers were submitted to the static (force plataform) and dynamic (Timed Up and Go) evaluation. Five series of one minute intervals were applied with the vibratory platform, with one minute of rest between each series and the equilibria were re-evaluated. For the verification of normality, the Shapiro-Wilk's test was applied and the Student's t test was used for statistical analysis, with a level of significance of p < 0.05. The balance comparisons between the moments before and after the vibration of the placebo group showed a significant difference in the variables' mean velocity of oscillation (p = 0.02) and total displacement (p = 0.02), since the remaining comparisons did not present a statistical difference. It is concluded that the study did not demonstrate a significant improvement in the static and dynamic balance of individuals with PD after a VCT session. [ABSTRACT FROM AUTHOR]

Objetivo: Identificar o efeito de variáveis mecânicas e fisiológicas sobre o nível de desempenho no judô, sendo elas: controle do equilíbrio; força de preensão palmar; altura de salto; potência mecânica muscular dos membros inferiores; índices de elasticidade (IE) e de fadiga (IF). Métodos: Amostra composta por 17 atletas de judô, de ambos os sexos, recrutados de forma intencional e não probabilística. Cada voluntário participou de uma bateria de testes realizada em um único encontro. Foi aplicado o teste de desempenho específico de judô Special Judo Fitness Test – SJFT. Na sequência realizou-se medidas de equilíbrio, preensão palmar e os testes de salto para: avaliação da potência mecânica muscular dos membros inferiores; IE e IF. Utilizou-se o Generalized Linear Model (GLzM). Resultados: Apenas a altura no Squat Jump (A_SJ), que apresentou efeito positivo, e o IE, que apresentou negativo, afetaram o desempenho no SJFT. Conclusão: A A_SJ e o IE afetaram o desempenho no SJFT, sendo que maiores alturas de salto SJ predizem um desempenho aprimorado; e maior contribuição da energia elástica, com valores mais altos de IE, prediz um desempenho piorado. As demais variáveis (potência muscular, altura no Counter-Movement Jump, preensão palmar, equilíbrio e IF) não afetaram o desempenho no SJFT.

RESUMO As órteses são recursos terapêuticos indicados para proteger, corrigir deformidades ou auxiliar em certas funções; porém, seu uso pode acarretar compensações proximais no ombro. O objetivo deste estudo é avaliar a influência da órtese estática dorsal do punho, em 30° de extensão na biomecânica do ombro e cotovelo, em 25 voluntários assintomáticos durante uma tarefa funcional. Os dados da amplitude de movimento e ativação muscular foram adquiridos de forma sincronizada e simultânea durante parte do teste funcional Elui, que simula alimentação, dividida em alcance, deslocamento e liberação, de uma jarra, nas condições sem e com órtese. Para possibilitar a comparação entre os diferentes sujeitos e músculos, os dados foram analisados pela integral do sinal EMG de cada músculo e, para análise cinemática, foram construídos sistemas de coordenadas de marcadores pré-definidos. Os sinais captados foram filtrados e processados por um software personalizado, e utilizou-se o teste t para amostras pareadas - software SPSS, p

ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors.

La solución de los problemas de salud en este milenio requiere de la interrelación entre diferentes ramas científicas y tecnológicas, tales como la Biomecánica, la simulación computacional, la ingeniería y las ciencias médicas. La importancia de la comunicación interdisciplinaria en las universidades fundamenta la creación de un grupo de investigación que fusiona el conocimiento de la mecánica clásica con las disciplinas de la salud y la participación de pacientes, técnicos, ingenieros, médicos así como estudiantes de pregrado y postgrado. En el trabajo se muestran algunas líneas de trabajo y resultados de lo que hoy se realiza en el Grupo de Bioingeniería y Biomecánica de la Universidad de Camagüey Ignacio Agramonte Loynaz.

Recently, there has been increased interest in the use of natural jaws for better results in bone fixation studies. Thus, the sheep mandible has been chosen for such studies. The aim of this study was to evaluate the length and resistance of the sheep mandible when submitted to a compression test with freedom in the three axes of space. Seventy fresh sheep (Ovis aries) mandibles were used in this study. Initially, the soft tissues were removed, and measurements of the mandible size were performed. Fifty mandibles were selected for mechanical testing based on the mean values from this assessment. The mandibles were joined by fixation in the symphyseal region and were tridimensionally deformed. A metallic support suitable for study of the mandible under efforts with freedom in the three axes in space was used. For this test, three displacement cycles were applied. Based on the mean stiffness, 35 mandibles were selected. The mean value of the sheep mandible mensuration was 13.6 cm ± 0.53 cm. The mean value of the sheep mandible stiffness was 153.5N ± 54.0 N. These data are useful for future studies on fixation systems for fractures and orthognathic surgery. [ABSTRACT FROM AUTHOR]

The association between contextual interference effect (CIE) and kinematic measures has been little investigated. The purpose of this study was to investigate the CIE on velocity and acceleration kinematic profiles of upper limb. Thirty-two subjects (23,7 ± 3,3 years) were assigned to groups of blocked practice (GPB) and random practice (GPA). The task consisted in achieve three targets in three specific sequences as quickly and accurately as possible. The study was designed in acquisition phase and transfer test. The variables of performance were reaction time, movement time and response time and the kinematic variables were peak of speed, relative time to peak of speed and number of peak acceleration points. The main findings showed that GPA showed lower movement time and response time than GPB. Regression analysis indicated that change in peak velocity during practice was associated to the change of the reaction time from practice to the transfer test. As peak velocity is a measure related to preprogramming, it is suggested that central control was essential to the CIE. [ABSTRACT FROM AUTHOR]

This article presents a study on the kinematic changes in the reaching movement in people with Parkinson's disease with freezing of gait. The objective of the study was to evaluate the kinematics of the upper limbs in people with Parkinson's during unilateral reaching. The results showed that people with Parkinson's had longer movement duration and lower peak velocity for both upper limbs, as well as longer reaction time for the more affected limb. Correlations were also found between peak velocity and disease subtype, dynamic balance, and freezing of gait. It is concluded that people with Parkinson's had inferior performance in reaching compared to the control group. [Extracted from the article]
