The “Linsanity” phenomenon attracted an increase in attention toward the National Basketball Association (NBA) for a short period of time. Drawing on self-categorization theory to elucidate current literature on team identification, this research proposed a conceptual model delineating the social psychological process for international consumers during the phenomenon. Using an online survey with a convenience sample in Taiwan, structural equation modeling, including confirmatory factor analysis (CFA) and path analysis, validated the conceptual model and confirmed the relationships between constructs in the model. Results indicated that Taiwanese identification positively influenced player identification, while player identification mediated the relationship between Taiwanese identification and team identification. Consequently, team identification positively influenced NBA involvement. The research findings together contribute to explicating the mechanism behind consumers’ self-categorization process during the “Linsanity” phenomenon while offering implications for international sport marketing. The research concludes with suggestions for future research. 相似文献

One of the key issues of team sport championships is competitive balance. One of the dimensions of competitive balance is concerned with the differences in sporting capabilities of teams within a season. The aim of this study is to evaluate competitive balance in Greek basketball and handball championships in relation to the presence and number of foreign players. The examined periods are from 1965–1966 to 2012–2013 (n = 47) for basketball and from 1983–1984 to 2012–2013 (n = 30) for handball. Foreign players appeared in basketball starting from 1988 while in handball from 1999. For each season and sport, two global and three special indices that capture competitive balance in the multileveled championship structure were calculated. Results showed that the number of foreign players per team is dependent on the country's macroeconomic status and in its turn improves the overall competitiveness, as well as competitiveness at the relegation level. In handball foreign players appeared later and in lesser numbers than in basketball. The increase in competitiveness of the national basketball league as a result of the increase in numbers of foreign players across all teams was followed by an upsurge in the quality, performance and achievements of the top teams participating in the European competitions. 相似文献

ABSTRACTThis study aimed to examine: (i) the effect of decreasing training load (TL) during taper weeks on physical match activities in professional soccer players, and (ii) to disclose the relationship between weekly TL and physical match activities. Rating of perceived exertion was collected after each training session and match to quantify the TL in 19 professional players over 17 standard and 7 taper weeks during the season. Physical match activities were quantified by a computerised match analysis system and compared between standard training and taper weeks. Compared to standard weeks, the duration and frequency of training sessions during the taper weeks decreased (?21.7% and ?18.8%, respectively; P < 0.01) with no change in intensity (?4.8%; P = 0.09). Consequently, the weekly TL decreased during the taper weeks (?25.5%; P < 0.01). Increases in distance covered by intense running (+15.1%; P < 0.05), high-intensity running (HIR) (+15.7%; P < 0.01), number of sprints (+17.8%; P < 0.05) and number of high-speed runs (+15.7%; P < 0.05) were observed during the seven matches played after the taper weeks. High relationships were observed between TL and HIR distance covered, number of HIR and number of sprints (r = ?0.53; r = ?0.55; r = ?0.65, respectively; P < 0.01). Decreasing TL during taper weeks by reducing training duration and frequency but maintaining intensity was associated with an increase in physical activities during matches. However, it needs to be determined whether tapering or other match factors led to the changes in match activity. 相似文献

The concept of physical literacy (PL) has been suggested as one that can offer a catalyst for a new emphasis in physical education (PE). In the broadest sense, a physically literate child is confident, active, and can maintain health enhancing physical activity (PA) for life. PL includes engagement in PA, physical competence, and PA motivation, confidence, knowledge and understanding. The purpose of this study is to investigate the levels of PL in Irish adolescents. As part of a larger study data were collected from 535 (12.78?±?.42 years) adolescents across 20 schools, to measure physical activity, physical competence, and psychological correlates of physical activity. Less than half of participants are accumulating the minimum of 60 minutes of PA daily required for health (49% males, 26% females). Data highlight that Irish youth are performing ‘below par’ across the domains of PL, with cardiovascular fitness (45% of males and 67% of females reaching ‘optimal’ target) and self-efficacy (53% of males and 46% of females reaching ‘optimal’ target) of greatest concern. Findings are discussed in the context of the need for a targeted direction in post-primary PE in Irish schools to increase levels of PL in Irish adolescents. 相似文献

Team identification and sports fandom as predictors of fan aggression: The moderating role of ageing
《Sport Management Review》2019,22(2):194-208
In the current study, the explored the moderating role of ageing in the relationship between team identification/fandom and fan aggression. The authors used an online panel-based survey that offered access to a realworld population of sports fans. Participants were 740 fans of Israeli professional basketball. Results from structural equation modelling demonstrated that older fans reported higher levels of mere sports fandom and lower levels of self-reported aggression and acceptance of aggression. Moreover, age moderated the relationships between team identification (or fandom) and self-reported aggression, such that team identification (or fandom) was more strongly associated with selfreported fan aggression among younger fans than among older fans. The moderating role of age in the relationships between team identification (or fandom) and perceptions of appropriateness of aggression was not supported. The findings contribute to our theoretical understanding of the role of ageing in the relationship between fan identification and fan aggression. Based on these findings, the authors assert that managers might particularly benefit from leveraging the potential, but often neglected, segment of senior fans, since older fans can play a key role in reducing the level of aggression during competitive sports events. Suggestions for future research are also discussed. 相似文献

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R2 values of >0.85 for all variables excluding deadlift mean velocity (R2 = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance. 相似文献

Really simple syndication (RSS) is becoming a ubiquitous technology for notifying users of new content in frequently updated web sites, such as blogs and news portals. This paper describes a feature-based, local clustering approach for generating overview timelines for major events, such as the tsunami tragedy, from a general-purpose corpus of RSS feeds. In order to identify significant events, we automatically (1) selected a set of significant terms for each day; (2) built a set of (term–co-term) pairs and (3) clustered the pairs in an attempt to group contextually related terms. The clusters were assessed by 10 people, finding that the average percentage apparently representing significant events was 68.6%. Using these clusters, we generated overview timelines for three major events: the tsunami tragedy, the US election and bird flu. The results indicate that our approach is effective in identifying predominantly genuine events, but can only produce partial timelines. 相似文献
