We investigated in normal human subjects the effect of changing the initial direction on the kinematic properties of ®gure `8' movement performed as fast as possible by the right arm extended in free space. To this end, the motion of the index ®nger was monitored by the ELITE system. The ®gure `8' movement was characterized by a complex tangential velocity pro®le (Vt) presenting 5 bell-shaped c...

Measuring and evaluating tactical behavior is one of the main goals in performance analysis in professional soccer. A specific tactical approach may present the difference between winning and losing, especially in the highest level of competition. So fare tactical behavior is mostly determined by using one or two variables, like ball possession or number of passes. Within this study, we introdu...

The dual-task methodology, conducting two tasks simultaneously, may provide better validity than the traditional single-task tests in the environment that is closely related to real sport competitions. The purpose of this study is to determine the reliability and validity of a dual-task test that aims to measure the reaction time and skill proficiency in roundhouse kicks in elite and sub-elite ...

The aims of this study were to establish the physical and physiological attributes of elite and sub-elite Malaysian male badminton players and to determine whether these attributes discriminate elite players from sub-elite players. Measurements and tests of basic anthropometry, explosive power, anaerobic recovery capacity, badminton-specific movement agility, maximum strength, and aerobic capac...

BACKGROUND Low back pain in junior Australian Rules footballers has not been investigated despite findings that back pain is more prevalent, severe and frequent in senior footballers than non-athletic controls and findings that adolescent back pain is a strong predictor for adult back pain. The aim of this study was to determine the prevalence, intensity, quality and frequency of low back pain ...

This study was designed to define the most important factors to predict freestyle performance times in 135 elite master swimmers by prediction models which include age, anthropometric and strength variables. To cross validate these equations found for Elite swimmers, we used a group composed by 126 lower technical level age and experience matched master swimmers. Results demonstrated that age, ...
