The purpose of this study was to examine the effects of static, dynamic, and the combination of static and dynamic stretching within a pre-exercise warm-up on the Illinois agility test (IAT) in soccer players. Nineteen professional soccer players (age = 22.5 ± 2.5 years, height = 1.79 ± 0.003 m, body mass = 74.8 ± 10.9 kg) were tested for agility performance using the IAT after different warm-u...

conclusions there was a higher incidence of genu varum in soccer players than in control adolescents; the stress and load imposed on the knee joint led to more severe genu varum. results both soccer players and controls had genu varum. however, the incidence of genu varum was higher in the soccer players (p = 0.0001) and it was more prevalent in the 16-18 year age group (p = 0.0001). the result...

The present systematic review and meta-analysis aimed to assess the perturbations in hormonal and psychological homeostasis in response to soccer match-play. These perturbations were explored according to match outcome (i.e., win versus loss), gender, type of contest (i.e., competitive versus non-competitive fixtures) and competitive level (i.e., novice versus high-level). The review was conduc...

Teamwork requires organisation, strategies and coordination. At every level of designing a multi-agent system, it is important to support these properties to build eeective teams. A team approach has the advantage of reducing the complexity of the task through distribution of responsibilities resulting in better utilisation of resources, robust behaviour, and providing more options against comp...

play (and win) soccer against the human soccer world champion in the year 2050? This question is not easy to answer, and the idea is quite visionary. However, this is the goal of the RoboCup Federation. There are serious research questions that have to be tackled behind the scenes of a soccer game: perception, decision making, action selection, hardware design, materials, energy, and more. Robo...

In a soccer robot game, the environment is highly competitive and dynamic. In order to work in the dynamically changing environment, the decision-making system of a soccer robot system should have the features of -exibility and on-line adaptation. This paper proposed a strategy-based decision-making system for a soccer robot system. The decision system is based on the proposed self-organizing f...

Heading the ball is a fundamental skill in soccer. But, recent studies have shown that players who headed the ball frequently were more vulnerable to concussion. To record head impacts and flag potential concussions, intra-oral and head-mounted devices such as Vector MouthGuard and Biosystems xPatch have been developed. However, they are yet to gain wider acceptance, perhaps because they are in...

Teamwork requires organization, strategies and coordination. The design of a multi-agent system should support these conceptual properties for constructing eeective teams. The advantages of a teamwork approach is the reduction in complexity of the task through distribution of responsibilities, resulting in better utilization of resources, robust behaviors, and a greater variety of behaviors aga...
