Background. The several types of running in the team sports such as basketball, soccer and rugby, vary according to physical characteristics sports. In particular, basketball is characterized by continuous acceleration deceleration phases, which entails greater energy expenditure. This study aimed assess strength decrease lower limbs expenditure at different conditions (n=4) with/without ball d...

Performance assessment has become an invaluable component of monitoring participant's development in distinct sports, yet limited and contradictory data are available in trained subjects. The purpose of this study was to examine the relationship between ball throwing velocity during a 3-step running throw in elite team handball players and selected measures of rate of force development like for...

Recognizing the arbitrary standard FIFA ball is a significant ability for soccer robots to play competition without the constraint of current color-coded environment. This paper describes a novel method to recognize arbitrary FIFA ball based on omni-directional vision system. Firstly the omni-directional vision system and its calibration for distance map are introduced, and the conclusion that ...

BACKGROUND Improved oxygen uptake improves soccer performance as regards distance covered, involvements with the ball, and number of sprints. Large improvements in oxygen uptake have been shown using interval running. A similar physiological load arising from interval running could be obtained using the soccer ball in training. OBJECTIVES The main aim was to study physiological adaptations to...

Linear optic trajectory theory claims that people catch balls by running in a direction that keeps an optic trajectory of the ball linear. The authors show a range of ball trajectories for which departures of the optic trajectory from linearity do not predict which direction people will run, and the direction they choose does not correct these departures. Data from a wide range of ball trajecto...

Young soccer players are usually trained with adult-training methods, even though the physiological adaptations are likely to be very different compared with adults. In contrast, some have suggested training preadolescents only with coordination training. The purpose of this study was to investigate whether coordination or repeated-sprint training better improved speed over 20 m, with and witho...

In order to identify biomotor structures in elite female handball players, factor structures of morphological characteristics and basic motor abilities of elite female handball players (N = 53) were determined first, followed by determination of relations between the morphological-motor space factors obtained and the set of criterion variables evaluating situation motor abilities in handball. F...

In an analysis of the physical demands when running with the ball in professional soccer, this study (1) determined activity profiles during match-play, (2) examined effects of fatigue, and (3) investigated differences according to playing position. Thirty French League 1 matches from two competitive seasons (2007-2008, 2008-2009) were analysed using multi-camera computerized tracking. Players ...

PURPOSE The purpose of this study was to examine the relationship between ball-throwing velocity during a 3-step running throw and dynamic strength, power, and bar velocity during a concentric-only bench-press exercise in team-handball players. METHODS Fourteen elite senior male team-handball players volunteered to participate. Each volunteer had power and bar velocity measured during a conce...
