The present study examined the hypothesis that feedback inducing an external focus of attention enhances motor learning if it is provided frequently (i.e., 100%) rather than less frequently. Children (10- to 12-year-olds) practiced a soccer throw-in task and were provided feedback about movement form. The feedback statements, provided either after every (100%) or every third (33%) practice tria...

Robotic soccer is a challenging research area, which involves multiple agents that need to collaborate in an adversarial environment to achieve specific objectives. Here we describe the Sharif CESR small robot team, which was participated in Robocup 2001 small size league in Seattle, USA. This paper explains the overall architecture of our robotic soccer system. Figure 1 shows a picture of our ...

A real time vector field based path planning for attack mode robot and a Petri-net state diagram approach for robot’s role selection for robot soccer games are proposed in this paper Robot soccer game has dynamic environments as different robots intentionally affect the environment in unpredictable ways in a competitive setting. A soccer-playing robot has to take an appropriate action according...

From the standpoint of multi-agent systems, soccer (association football), which is just one of usual team sports, make a good example of problems in the real world which is moderately abstracted. We have chosen soccer as one of standard problems for the study on multi-agent systems, and we are now developing a soccer server, which provides a common test-bench to various multi-agent systems. We...

In order to create a cooperative architecture for multiagent systems in robotic soccer, it is necessary to model and understand the human soccer concepts to use and express them computationally. This work presents the main features for a multi-agent cooperative architecture based on human soccer concepts. The architecture can be applied to different categories of RoboCup. To test its performanc...

Background. Previous studies have shown that an external versus the internal focus of attention is an effective and efficient method to improve athleteschr('39') performance under anxious conditions. Objectives. The current study aimed to assess the effect of the practice with a distinct focus of attention on the penalty kicking performance of adolescent soccer players with different expertise...

OBJECTIVES In reviewing the literature on sports injuries, few studies could be found in which exposure related incidences of injury in different types of sport were compared. These studies indicated that ice hockey, handball, basketball, soccer, and rugby are popular team sports with a relatively high risk of injury. The aim of the study was to compare the characteristics and incidence of inju...

Radiochemical methods of analysis possess some special advantages , such as rapidity and great sensi t ivi ty, and can on occasion provide results which would not be attainable by other means. They are finding an increasing number and variety of applications not only in pure research, but in medicine and heal th, in many industries such as mining, text i les , metallurgy and the oil industry, a...

The aim of this study was to examine the effect of a six-week combined jump and sprint training program on strength-speed abilities in a large sample of youth competitive soccer players. It was hypothesized that the experimental training group would enhance their jumping and sprinting abilities. Enhancement of kicking performance was also hypothesized due to an expected increase in explosive st...
