Electrocardiogram (ECG) and echocardiography are mandatory in preparticipation cardiac screening in soccer players. Abnormal ECG findings usually require follow-up investigations. The main aim of this study was to compare the prevalence of abnormal ECG findings in male professional soccer players according to European Society of Cardiology's (ESC) recommendations and the Seattle criteria, and t...

Soccer is a game in which fatigue can negatively influence players' performance. Few studies have examined the practical effects of fatigue on soccer performance skills. Thus, the aim of the present study was to evaluate the effect of fatigue, acutely induced by means of a soccer specific circuit on ball velocity. Ten amateur soccer players (age 27.3 ± 5.25 yr; experience 16,8 ± 6.05 yr; level ...

An algorithm to extract key features from a soccer video is proposed. In this algorithm, the soccer field, individual players and the ball are detected and tracked in each frame. The work done can be used as a basis for robust feature extraction of soccer games that can be expanded to provide automated analysis, interpretation of soccer games. Keywords-Soccer, analysis, field, player, ball, det...

Fast browsing video contents not only is an important research issue, but also has a variety of potential applications, especially for sports videos. In this paper, we propose a practical solution to extract highlights from soccer videos, which is based on the structure analysis of broadcast soccer video. First, the broadcast soccer video is structured into a soccer pyramid composing a series o...

This article is a first approach to the use of Rete algorithm to design a team of robotic soccer playing agents for Robocup Soccer Server. Rete algorithm is widely used to design rule-based expert systems. Robocup Soccer Server is a system that simulates 2D robotic soccer matches. The paper presents an architecture based on CM United team architecture for Robocup Soccer Server simulation system...

Relative age effects (RAEs) refer to age differences in the same selection year. In this study, 6,229 female soccer players representing the entire Swiss female soccer population were evaluated to determine the prevalence of RAEs in Swiss women’s soccer. Significant RAEs existed in the self-selected extracurricular (n = 2987) soccer teams and the subgroup of talent development teams (n = 450) i...

The aim of this study’s interpretive structural model (ISM) was to ascertain the factors that affect the intent to purchase original brand soccer balls. Methods. First, by a study of the literature and by the use of the Delp...

Many soccer fans prefer to watch a summary of football games as watching a whole soccer match needs a lot of time. Traditionally, soccer videos were analyzed manually, however this costs valuable time. Therefore, it is necessary to have a tool for doing the video analysis and summarization job automatically. Automatic soccer video summarization is about extracting important events from soccer m...

In this paper, we make two contributions. First, we present a new domain, called Segway Soccer, for investigating the coordination of dynamically formed, mixed human-robot teams within the realm of a team task that requires real-time decision making and response. Segway Soccer is a game of soccer between two teams consisting of Segway riding humans and Segway RMP-based robots. We believe Segway...

The verbal feedback given to junior soccer players potentially heading to a professional career is essential for technical and tactical skill development. The aim of this study is to examine whether differences exist in feedback between coaches of junior elite soccer teams and coaches of junior amateur soccer teams. The coaches of a junior elite soccer team and a junior amateur soccer team in N...
