Introduction: The relative age effect is prevalent in different elite team sports. However, little known about this phenomenon high-level adult male futsal players. Aim: present study aimed to investigate the prevalence of Brazilian players, and its relationship with playing position goals scored on Brazil National Futsal Leagues (BNFL) from 2016 2020. Methods: distribution birth dates, positio...

A design and implementation method of a robot soccer system with three vision‐based autonomous robots is proposed in this paper. A hierarchical architecture with four independent layers: (a) information layer, (b) strategy layer, (c) tactics layer, and (d) execution layer, is proposed to construct a flexible and robust vision‐based autonomous robot soccer system efficiently. Five ...

The aim of the study was to define biomotor characteristics that determine playing performance and position in female handball. A battery of 13 variables consisting of somatotype components (3 variables), basic motor abilities (5 variables) and specific motor abilities (5 variables) were applied in a sample of 52 elite female handball players. Differences in biomotor characteristics according t...

Robot soccer competition provides an excellent opportunity for integrated robotics research. In particular, robot players in a soccer game must recognize and track objects in real-time, navigate in a dynamic field, collaborate with teammates, and strike the ball in the correct direction. All these tasks demand robots that are autonomous (sensing, thinking, and acting as independent creatures), ...

There are many features that athletes must have in order to be successful futsal. One of these is agility based on rapid and sudden change direction. This study was conducted examine the futsal players playing different positions (goalkeeper, defense attack) analyze their responses tests. The research data were obtained by subjecting indoor soccer Universities Futsal League tests revealing answ...

Elbow problems in goalkeepers in team handball ‘‘handball goalie’s elbow’’ is common. The accepted mechanism in the common injuries is hyperextension of the elbow. The purpose of this study was to describe the elbow position at the time of impact of the ball on the hand. This study is based on video-analysis. Fifteen handball goalies (ten females and five males) who had been playing handball fo...

The drag-flick is more efficient than hits or pushes when a penalty corner situation is in effect in field hockey. Previous research has studied the biomechanical pattern of the drag-flick, trying to find the cues for an optimal performance. On the other hand, some other studies have examined the most effective visual pick-up of relevant information in shots and goalkeeper anticipation. The aim...

Vision provides us with much information about distal spaces, and enables us to formulate expectations about how objects move. In this work, we consider how images, together with motor and performance data, can be used to form ”maps” or a holistic view of any motion. For example if the learner knows how to throw a ball, it may be able to use the map to see that it also applies to kicking, or ca...

Our study aimed to verify whether the manipulation of task constraints has different effects according age group. Another objective was physiological and physical responses in formats small-sided games (SSG). Each team SSGs composed 4 players (4x4). The participants research are young football U-12 (n=8) U-15 (n=8), affiliated with a club certified as training entity, competed regional champion...
