In broadcast sports video, the scoreboard is attached at a fixed location in the video and generally the scoreboard always exists in all video frames in order to help viewers to understand the match’s progression quickly. Based on these observations, we present a new localization and recognition method for scoreboard text in sport videos in this paper. The method first matches the Scale Invaria...

It usually occurs that in important matches, athletes often play abnormal of their sport technique as they are too concerned about the competition result, and this is called Choking phenomenon. How to explain and control this from the perspective of the present psychology has become a widely discussed hot issue in the field of sports psychology. By research on the occurrence conditions of athle...

Tactical match performance depends on the quality of actions of individual players or teams in space and time during match-play in order to be successful. Technological innovations have led to new possibilities to capture accurate spatio-temporal information of all players and unravel the dynamics and complexity of soccer matches. The main aim of this article is to give an overview of the curre...

During the last twenty years, a lot of research was conducted on the sport elimination problem: Given a sports league and its remaining matches, we have to decide whether a given team can still possibly win the competition, i.e., place first in the league at the end. Previously, the computational complexity of this problem was investigated only for games with two participating teams per game. I...

We investigated the effect of increases in task complexity on the dual-task draw-and-pass performance of professional rugby league players. Moreover, we determined the relationship between dual-task draw-and-pass proficiency measured in isolation and draw-and-pass performances as they occurred in actual competitive matches. In Study 1, 12 rugby league players performed 2-on-1 and 3-on-2 attacki...

OBJECTIVES Anthropometric and physiological profiles of national sepak takraw players were determined. METHODS Thirty nine players, specialising in the three playing positions (tekong/server, feeder, and killer/spiker) were divided into three age categories of under 15 (U15), under 18 (U18), and under 23 (U23) years of age. Height, weight, percent body fat (%bf), maximum oxygen consumption (V...

BACKGROUND To the authors' knowledge, no study has investigated the concurrent repeated, high-intensity (RHIA) and repeated-sprint activity (RSA) of intermittent team-sport competition. PURPOSE In this study, they report on the RSA of elite women's football competition. In addition, they describe the nature of RHIA (eg, striding and sprinting activities) that involve a high energy cost and ar...

Performance indicators in sport are ofte n specific to individual perform ances rather than being typical for perform ers. Therefore, H ughes et al. (2004b) developed the concept of nor mative profiles of sports perform ance and a m eans of determining the number of m atches required for perform ance indicators to stabilise within a tolerable percentage error of the typical mean for the perform...

Over the years, the concept of leadership has experienced a paradigm shift − from solitary leader (centralized leadership) to de-centralized leadership or distributed leadership. This paper explores the idea that centralized leadership, as earlier suggested, negatively impacts team performance. I applied the hypothesis to cricket, a sport in which leaders play an important role in team’s succes...

With recent advances in sensor technologies, large amounts of movement data have become available in many application areas. A novel, promising application is the data-driven analysis of team sport. Specifically, soccer matches comprise rich, multivariate movement data at high temporal and geospatial resolution. Capturing and analyzing complex movement patterns and interdependencies between the...
