Online multi-player detection and tracking in broadcast basketball videos are significant challenging tasks. In this environments, the target distributions are highly non-linear, and the varying number of objects creates complex interactions with overlap and ambiguities. In this paper, we present a real-time multi-person detection and tracking framework that is able to perform detection and tra...

In a prospective study of 302 adolescent players in three ball games (soccer, handball and basketball), 119 incurred injuries. The injury incidence (number of injuries per 1000 playing hours) was 5.6 in soccer, 4.1 in handball and 3.0 in basketball. Ankle sprains accounted for 25 per cent of the injuries, finger sprains 32 per cent, strains in the thigh and leg 10 per cent, and tendinitis/apoph...

In the last two decades, basketball coaches have increasingly relied on statistical analysis to determine coaching strategies for their teams. Davidson College (USA) men’s basketball coach Bob McKillop divides each game into ten “rounds”, with a round ending at each media timeout and at halftime, and gives his team several “round” goals for every game. In this article we investigate how winning...

Martínez JA, Martínez L. A stakeholder assessment of basketball player evaluation metrics. J. Hum. Sport Exerc. Vol. 6, No. 1, pp. 153-183, 2011. In this research we examined the opinions of basketball stakeholders regarding several questions of special interests to valuate players. Players, coaches, agents, journalists, editors, bloggers, researchers, analysts, fans and chairs participated in ...

Somatotype ratings and percentage body fat of 131 elite Nigerian male athletes, average 24.2 years of age, and belonging to badminton (n = 18), basketball (n = 30), field hockey (n = 24), handball (n = 16), judo (n = 18), and soccer (n = 25) teams were determined. Basketball, handball and soccer players were taller and heavier, and had low percent fat values as compared with the other athletic ...

This case report examined the cardiovascular stress imposed on an experienced elite basketball referee during national competition. The average heart rate was similar for all matches, approximated 73% of maximum heart rate, and was experienced for most (>63%) of the match. Similar relative exercise intensity was demonstrated regardless of match play (men's v women's) and officiating type (two v...

Although the literature records instances of acute epidural haematoma and acute subdural haematoma related to playing basketball, there has not been a report of chronic subdural haematoma as a basketball injury. With the burgeoning interest in this sport in the United Kingdom and Europe, the possibility of this particular neurotrauma increases. Such an injury, along with the diagnosis and manag...

In the current study, variables grounded in social cognitive theory with athletes with disabilities were examined. Performance, training, resiliency, and thought control self-efficacy, and positive (PA) and negative (NA) affect were examined with wheelchair basketball athletes (N = 79). Consistent with social cognitive theory, weak to strong significant relationships among the four types of sel...

This paper proposes a framework for structure-based feature extraction in basketball zonedefense strategies. Firstly, a graphical representation for key-frames extracted from zone-defense video clips is introduced, where each key-frame is expressed in terms of a zone-defense graph, representing the positions of defenders and the ball. Secondly, defense-lines are defined and extracted from zone-...

A feature-representation method for recognizing actions in sports videos on the basis of the relationship between human actions and camera motions is proposed. The method involves the following steps: First, keypoint trajectories are extracted as motion features in spatio-temporal sub-regions called “spatio-temporal multiscale bags” (STMBs). Global representations and local representations from...
