Determination of the lactate threshold and maximal blood lactate steady state intensity in aged rats
(Cell Biochemistry and Function, 2009-08-01) [Artigo]
The reliability of the lactate threshold (LT) determined in aged rats and its, validity to identify an exercise intensity corresponding to the maximal blood lactate steady state (MLSS) were analyzed. Eighteen male aged ...
Effects of postural threat on walking features of Parkinson's disease patients
(Neuroscience Letters, 2009-03-13) [Artigo]
This study investigated whether or not gait kinematics among healthy older individuals and Parkinson's disease (PD) patients are influenced by postural threat. Eight healthy older individuals and eight PD patients were ...

Changes of glycogen content in liver, skeletal muscle, and heart from fasted rats
(Cell Biochemistry and Function, 2009-10-01) [Artigo]
Glycogen content of white and red skeletal muscles, cardiac muscle, and liver was investigated in conditions where changes in plasma levels of non-esterified fatty acids (NEFA) occur. The experiments were performed in fed ...
Motor perseveration during an A not B task in children with intellectual disabilities
(Human Movement Science, 2009-12-01) [Artigo]
This study was designed to identify perseverative reaching tendencies in children with intellectual disabilities (ID), over a period of 1 year, by using a version of the Piagetian A not B task modified by Smith, Thelen, ...
Análise de parâmetros de força e resistência dos músculos eretores da espinha lombar durante a realização de exercício isométrico em diferentes níveis de esforço
(Revista Brasileira de Medicina do Esporte, 2005-04-01) [Artigo]
A dor lombar tem demonstrado ser um achado comum em atletas e, particularmente, a sobrecarga na coluna lombar em conseqüência de um comprometimento da força ou resistência isométrica de músculos desse segmento, como resultado ...
A proposta biomecânica para a avaliação de sobrecarga na coluna lombar: efeito de diferentes variáveis demográficas na fadiga muscular
(Acta Ortopédica Brasileira, 2007-01-01) [Artigo]
OBJETIVOS: Analisar a fadiga de músculos lombares e determinar as variáveis demográficas relacionadas com a fadiga destes músculos. MÉTODOS: A atividade eletromiográfica (EMG) dos músculos iliocostal direito (IL-D), ...
Respostas pressóricas pós-exercícios com pesos executados em diferentes sobrecargas por mulheres normotensas
(Revista Brasileira de Medicina do Esporte, 2009-02-01) [Artigo]
O treinamento com pesos (TP) vem sendo amplamente recomendado para a melhoria de alguns componentes da aptidão física relacionada à saúde. Mais recentemente, vem-se discutindo o impacto do TP em indivíduos com disfunções ...
Does 75% of the difference between VO2 at lactate threshold and VO2max lie at the severe-intensity domain in well-trained cyclists?
(Science & Sports, 2009-11-01) [Artigo]
Aims. - The purpose of this study was to compare the critical power (CP) with exercise intensities measured as a percentage of the difference between VO2 at lactate threshold (LT) and maximal oxygen uptake (VO2max) (25, ...
Benefits of physical exercise on executive functions in older people with Parkinson's disease
(Brain and Cognition, 2009-03-01) [Artigo]
The benefits of physical exercise on cognitive functioning have been reported in the literature, but the potential benefits to slow the eventual decline in executive functioning (EF) caused by neurodegeneration from ...
