We investigate the time evolution of lead changes within individual games of competitive team sports. Exploiting ideas from the theory of random walks, the number of lead changes within a single game follows a Gaussian distribution. We show that the probability that the last lead change and the time of the largest lead size are governed by the same arcsine law, a bimodal distribution that diver...

BACKGROUND Several studies have explored motivating factors for sports participation for youth, but limited data is available regarding factors motivating inner-city children to participate in sports. METHODS A consecutive sample of parents (n=100 parents) and children (n=138 children) attending a health fair in an inner-city community were surveyed regarding motivating factors for enrolling ...

An evolutionary psycho-biological perspective on competitiveness dynamics is presented, focusing on continuous behavioral co-adaptations to constraints that arise in performance environments. We suggest that an athlete's behavioral dynamics are constrained by circumstances of competing for the availability of resources, which once obtained offer possibilities for performance success. This defin...

The internationalism of field-based team sports (TS) such as football and rugby requires teams to compete in tournaments held at low to moderate altitude (∼1200-2500 m). In TS, acceleration, speed and aerobic endurance are physical characteristics associated with ball possession and, ultimately, scoring. While these qualities are affected by the development of neuromuscular fatigue at sea level...

Professional sports have emerged as a lucrative business, with many opportunities for sports marketers to flourish. As this paper will show, professional sports teams unite to produce a league product that, while initially is produced to provide entertainment for spectators, is now sold to four distinct groups: first, fans who support leagues by attending games, following games on television an...

Background. Attention to the loyalty of fans to the long-term success of sports organizations has become increasingly important. On this note, it seems necessary to pay attention to the variables that predict and influence the loyalty of spectators. Objectives. The aim of this study was to determine the mediating role of satisfaction in the effect of team reputation and team quality on the loy...

PURPOSE The objectives of this study were to assess (1) the longitudinal associations of past moderate-to-vigorous physical activity (MVPA) and involvement in team sports during secondary school with depressive symptoms in early adulthood, and (2) the cross-sectional associations of current MVPA and involvement in team sports with depressive symptoms during young adulthood. METHODS Data were ...

Jumping and proprioception are important abilities in many sports. The efficiency of the proprioceptive system is indirectly related to jumps performed at specified heights. Therefore, this study recorded the ability of young athletes who play team sports to jump to a specific height compared with their maximum ability. A total of 154 male (age: 14.8 ± 0.9 years, body height: 181.8 ± 8.9 cm, bo...

The objective of this work was to compare the anthropometric and physical fitness characteristics of Brazilian adolescents who practise team court sports and to compare specific parameters obtained for adolescents with data from the general population. This was a cross-sectional study of 1,348 male adolescents grouped as follows: basketball players (n = 287), indoor soccer players (n = 665), ha...
