I received the Ph.D. degree in Human Movement Sciences from Universidade Federal do Rio Grande do Sul. My current topics of investigation are related to biomechanics and motor control of lower extremity. I live in Uruguaiana with my family. We are very close to Argentina, and a little bit far from Porto Alegre, the capital of our state.edit

Principais contribuições deste trabalho A utilização da bota Kangoo Jumps causa alterações na cinemática dos exercícios. Estudos futuros devem investigar as repercussões para o treinamento. INTRODUÇÃO A busca pela realização de exercícios físicos em academias, visando promoção da saúde e do bem-estar, tem sido muito freqüente nos últimos anos. A prática regular de exercícios físicos tem relação positiva com a diminuição de causas de mortalidade, uma vez que influencia a redução de muitos fatores de risco para o desenvolvimento de doenças [4]. Observa-se que muitos desses exercícios são constituídos de movimentos que envolvem habilidades motoras fundamentais, como o correr e o saltar. O saltar é um gesto motor associado como principal mecanismo de lesão desportiva [2]. Estas sobrecargas podem ser estimadas através das variações angulares das articulações dos membros inferiores [7, 13]. Os padrões cinemáticos da articulação do joelho durante a fase de aterrissagem de um salto poss...

With aging, it is important to maintain cognitive and motor functions to ensure autonomy and quality of life. During the acquisition of motor skills, it is necessary for the elderly to understand the purpose of the proposed activities. Physical and mental practice, as well as demonstrations, are strategies used to learn movements. To investigate the influence of mental practice and the observation of movement on motor memory and to understand the relationship between cognitive function and motor performance in the execution of a sequence of digital movements in the elderly. This was a cross-sectional study conducted with 45 young and 45 aged subjects. The instruments used were Mini-Mental State Examination (MMSE), Manual Preference Inventory and a Digital Motor Task (composed of a training of a sequence of movements, an interval and a test phase). The subjects were divided into three subgroups: control, mental practice and observation of movement. The elderly depend more strongly on...

Resumo A pronação excessiva da articulação subtalar é uma disfunção anatômica que provoca um desalinhamento no membro inferior alterando parâmetros biomecânicos desta articulação. Esta disfunção contribui para o desenvolvimento de lesões por uso repetitivo. O objetivo desta revisão de literatura foi analisar de forma sistemática a função ea prescrição de órteses para correção da pronação da articulação subtalar e antepé de ciclistas. Quarenta e quatro textos, entre artigos e livros publicados de 1985 a 2009 foram ...

The aim of the present study was to compare the bilateral external work and torque at four stages of an incremental maximal cycling. Eleven cyclists were evaluated on a cycle ergometer. Four stages of the incremental cycling workload were defined as 60, 75, 90 and 100% of maximal oxygen uptake (VO2Max). Pedal forces and kinematics variables were measured through each

The objectives of this study were to: (1) evaluate the resistive torque of an open kinetic chain strength-training machine for performing knee extensions, and (2) perform an analysis estimating internal forces in the tibiofemoral joint. During a fi rst phase of the study, measurements were taken of the machine under analysis (external forces), and then calculations were performed to estimate forces on the lower limb (internal forces). Equations were defi ned to calculate human force (HF), and the moment of muscular force (MMF). Perpendicular muscular force (MFp) and joint force (JFp), axial muscular force (MF") and joint force (JF"), and total muscular force (MF) and joint force (JF) were all calculated. Five knee angles were analyzed (zero, 30, 45, 60, and 90 degrees). A reduction was observed in HF at higher knee angles, while MF and JF also increased at the same time. HF was always lower than the load selected on the machine, which indicates a reduced overload imposed b...

It has been suggested that skin stimulation using tape glued to the skin over the Achilles tendon helps to improve postural control. It was recently shown that these effects might emerge only after muscle fatigue and not during non-fatigue standing. Here we tested the influence of skin stimulation on postural control before and after fatigue of ankle plantar flexors. Eighteen subjects stood quietly on a force plate while the center of pressure was monitored before and after fatigue of ankle plantar flexors muscles, with and without medical tape glued to the skin over the Achilles tendon. Our results suggested main effects of tape stimulation before fatigue (P<.05) and significant effect of tape stimulation after fatigue only for amplitude of center of pressure in the anteroposterior direction. The novelty of our study is that most of the center of pressure variables are improved by skin stimulation when the ankle plantar flexors are not fatigued. Therefore the benefits of tape stimulation during fatigue condition are questionable.
