O objetivo do presente estudo foi investigar a infl uencia da fadiga no equilíbrio do pé de apoio no momento do chute em jogadores de futebol. Participaram desta pesquisa 19 atletas de futebol divididos em dois grupos: grupo exaustão (GEX) que realizou um esforço com carga incremental até a exaustão em esteira rolante, e o grupo controle (GCE) realizou um esforço leve-constante de forma continua em esteira rola...

The aim of this study was to investigate the influence of fatigue on the balance of the support leg kick in soccer players. 19 soccer players were divided randomly into two groups: group exhauston (GEX), underwent an effort with incremental load at exhaustion on a treadmill, and the control group (GCE) underwent effort with constant lower load. Parameters of static balance in single support (one foot) were eval...
Running and cycling executed with the same duration and intensity may produce different biomechanical and metabolical responses during a fatigue protocol due to the mechanical overload and technical specificity of each modality. The purpose of this study was to evaluate the fatigue effects resultant from a 10 km running, preceded by cycling or running, on the stride pattern and electromyographic (EMG) signal. N...
The purpose of this study was to analyze the kinetic responses of running shoes submitted to prolonged use. Four shoes (R1, R2, T1 and T2) were used for 500 km except for T1 which was used for 1000 km. At every 100 km, Ground Reaction Force (GRF) and plantar pressure measurements were collected. In T2, there was a slight trend of increase in Loading Rate of the first peak of GRF with increasing distance. R1, R2...
The aim of this study was to compare the electromyographic signal and the stride frequency and length among different intensities of running: 60%, 80% and 100% of maximum speed in two incremental protocols. The study included 11 male runners. The protocols were performed with initial running speed of 10 km.hr-1, with increments of 1 km.hr-1 at every three minutes until exhaustion. The two protocols differed in ...
The prolonged use of a running shoe is thought to affect the efficiency of its impact attenuation properties. However, its effect over biomechanical variables has yet not been well understood. The aim of this study was to examine the influence of running shoe usage on ground reaction force and plantar pressure parameters. Three male runners received four running shoes each to use at their training sessions. The...
A corrida representa um importante segmento do triathlon, sendo precedida pela prova de ciclismo. A compreensão dos efeitos do ciclismo sobre o desempenho da corrida, portanto, se torna indispensável para a otimização dos resultados finais de uma prova. O objetivo desse estudo foi comparar as variáveis cinemáticas, eletromiográficas e o consumo de oxigênio da corrida no triathlon com àquelas de uma corrida isol...
