Abstract Athletes frequently have to adapt their skills to fast changes of play, often requiring the flexible execution of a particular movement skill with either hand. To assess the influence of sport-specific expertise and extensive sport training on human laterality, a video analysis of regular basketball games was performed for professional, semi-professional, and amateur players to investigate how non-dominant hand use and proficiency change with increasing expertise. Our results showed that the right-hand (i.e. dominant hand) bias in basketball players is reduced with increasing expertise (i.e. competitive level). Accordingly, we found that professional players use their non-dominant hand more often and with greater success than semi-professional and amateur players. This was true for most of the basketball-specific skills. Based on these results, we assume that increasing amounts of bilateral practice can lead to a shift in task-specific manual preference towards a higher use of both hands in competition, as well as to a higher proficiency for non-dominant hand actions in particular. From an applied perspective, the more frequent use and higher proficiency of the non-dominant hand in professional basketball players, compared with amateurs, suggests that the context-specific and skilled use of the non-dominant hand is crucial for successful play at higher competitive levels in the sport of basketball. 相似文献

The popularity and profitability of American gridiron football is beyond dispute. Recent polls put football as the overwhelming favorite of people who follow at least one sport and huge revenues are reported at both the professional and the university level. We know, however, that what is the case tells us little about what ought to be the case, and it is to the latter question that this paper is directed. I offer a three-pronged attack on the ethical acceptability of American football, both amateur and professional, based on (1) harm to the players, (2) objectification of the players, and (3) harm to others done by the players, leading to the conclusion that the sport, as currently constituted, is morally unacceptable. 相似文献

The aims of this study were to determine the type, frequency and amount of dietary supplement consumption among a group of professional basketball players. The type, amount and specific timing of supplement use were recorded by 55 professional basketball players from seven different teams of the First Spanish Basketball League. Most participants (58%) consumed dietary supplements. Multivitamins and vitamins were the most frequently used supplements among the athletes (50.9%), followed by sport drinks (21.8%), miscellaneous supplements (21.8%), amino acids (14.5%), proteins (12.7%) and carbohydrates (12.7%). The average daily dietary supplement was one capsule of multivitamins, one capsule of antioxidant vitamins, 0.2-1.0 g vitamin C, 10.3 g protein, 1.9 g amino acids, 16.2 g carbohydrates and 377 ml of a commercial sport drink. Although the proportion of participants who consumed dietary supplements before, during and immediately after exercise was 25.4%, 16.3% and 7.3% respectively, only a few consumed a potentially ergogenic supplement at these times. It would appear unlikely that the type or amount of dietary supplements consumed had a beneficial effect on the physical performance of these professional basketball players, with the possible exception of antioxidant vitamins and the commercial sport drinks. 相似文献

Does a young football (soccer) player’s birthdate affect his prospects in the sport? Scholars have found a correlation between early births in the competition year among young players within the same cohort and improved chances in sports as they advance to other stages. This article is one of the first studies to ask this question about a male premier league in Latin America – the Argentinian ‘A’ league. It uses a large-N data-set of all players in the period 2000–2012, around 3000 players. The article finds a large effect of the player’s relative age on his prospect to become a professional, though the effect is only present in the case of Argentinian-born players. The effect evaporates once a set of measures are employed to compare professional players with one another. The article contributes to the discussion of the biased effect of seemingly neutral institutional policies, and its conclusions may shed light in other areas. 相似文献

This case study explores how the National Basketball Association (NBA) can rebuild its reputation in response to recurrent player scandals. The case centers on a reputation management firm that has been contracted by the league. The firm has been asked to develop programs that will permit players to make better decisions in their personal lives. NBA commissioner Adam Silver believes such programs will curb the likelihood of future player scandals, thereby enhancing the players’ lives and limiting their ability to damage the league's reputation. To commence the process, the firm has been invited to sit-in on a meeting with Commissioner Silver and a group of NBA staff members who have past work experiences assisting players with their transition to the NBA.This reputation management case study is positioned in two key areas: impression management and employee assistance programs (EAPs). Upon reading the case, answering the provided questions, and completing the activities, students should come to a better understanding as to how to proactively manage corporate reputation. While fictitious names are given, the case study is based on actual interviews with current NBA staff members. The case is ideal for courses pertaining to strategy, policy, organizational behavior, and human resource management. The case could also be useful for sport marketing and sport finance courses if adapted to investigate how the created programs are important for branding and value. 相似文献

The International Olympic Committee (IOC) requires cities that bid for the Olympic Games to formulate a legacy strategy. This case follows a sport professional tasked with developing an Olympic bid for their city. Specifically, the case considers various legacy outcomes including: destination image, tourism, cost, venues, housing, and social legacies. The case is written with anonymity of the actual city so that the instructor can adapt the case to a specific city. The case is particularly useful for courses covering sport tourism, stakeholder management, event management, or sport economics and finance. 相似文献

Tennis featured in every Olympics from 1896 to 1924, after which disagreements between the International Olympic Committee (IOC) and the International Lawn Tennis Federation (ILTF) on matters pertaining to organisational control and the amateur eligibility of players led to tennis being removed from the Olympic Games as a full-medal event until the 1988 Seoul Olympics. This paper traces the steps of the sport’s reinstatement, from when efforts commenced in the 1950s, setting this development in the contexts of: broader political movements, shifting IOC leadership, burgeoning commercialisation of Olympic sport, the concomitant push for professionalisation and the declining influence of amateur ideals within both the Olympic movement and international tennis. Under the leadership of the amateur stalwart Avery Brundage, the IOC stymied attempts to facilitate tennis’s re-entry, challenging both the ILTF on failing to deal with widespread ‘sham-amateur’ practices and the avaricious promoters luring amateur players toward the professional ranks. Brundage and the IOC also strongly condemned the move to ‘open’ tennis and an acceptance of full-blown professionalism. Only a change in leadership, firstly with Lord Killanin and then the progressive reformer Juan Antonio Samaranch, did the IOC recognise the value of tennis within the Olympic movement, which by then had itself become increasingly money-oriented. 相似文献

ABSTRACTThe aims of this study were to examine the medium-term effects of previous experiences during early stages of sport development on physical capacities of under-13 (U-13) talented basketball players and, to identify variables that discriminated under-14 (U-14) national team training camp selection. Anthropometrical and physical measurements were collected during a basketball training camp. Previous sport experiences (6–10 years), maturity offset, power outputs for jumping and sprinting were determined. A cluster analysis was used to allocate the subjects according to their different levels of sport experiences (more specialized vs. less specialized) to allow creating a dummy variable for the subsequent analysis of the physical variables. A stepwise discriminant analysis was computed to identify the construct that best classifies selected and non-selected players for U-14 national team training camp. The less specialized group outscored more specialized in all physical parameters, irrespectively of gender. The Abalakov Jump Peak Power and Predicted Adult Height (PAH) could successfully discriminate selected from non-selected players for U-14 national team training camp in boys and PAHin girls. The diversified and non-specific sport stimulus during early ages seem to be determinant to the acquisition and development of fundamental movement skills of talented basketball players. 相似文献

排球运动员接发球过程中视觉搜索特征的研究 总被引：2，自引：0，他引：2
以33名不同水平排球运动员为被试,将时间阻断范式、眼动记录技术相结合,探讨排球运动员接发球过程中的视觉搜索特征。结果表明:在接发球过程中,不同水平排球运动员的视觉搜索特征存在显著差异。优秀排球运动员可以根据运动情景中任务的变化迅速调整视觉搜索模式,在接发球的预期阶段采用了注视次数少、注视持续时间长、眼跳距离小、注视轨迹简单、集中的搜索模式;在动作操作阶段采用了注视次数多、注视持续时间短、眼跳距离大、注视轨迹分散成网状的搜索模式。优秀排球运动员对发球落点进行预判时,在反应时和准确性指标上存在明显的优势,但是,随着运动水平的提高,反应准确性不是优秀排球运动员预期能力的主要区分标准。提示:对于测试、评价运动员在运动情景中的信息加工处理能力不能根据单一运动情景的眼动特征进行,要综合运动情景中的不同任务的眼动指标和行为预判探讨运动员在运动过程中的视觉搜索特征。 相似文献

AbstractThe movement of professional cricketers from South Africa to England to play in County Cricket has expanded since the late 1960s. It became more attractive during the period of South African isolation and some players saw English cricket as a route to play at Test match level through changing national allegiance. This paper explores the role of law in facilitating movement in two ways. First, in the case of Greig, the attempt to ban players who chose to participate in the new commercial venture, World Series Cricket, was overturned. Second, in the Kolpak case a decision of the European Court of Justice paved the way for South Africans and Zimbabweans to abandon their national side and play in England as domestic players without the usual constraints applied to overseas players. The opportunity was taken by numerous players because of the political upheaval in cricket that was contemporaneously taking place in both South Africa and Zimbabwe. The movement of players caused concern in both South Africa and England and led to a re-consideration of the financial relationships between governing bodies and players. 相似文献

This case study involving the New Zealand Breakers basketball team explores key factors relating to the home venues of sport teams. The case study is suitable for use in a variety of undergraduate courses such as sport management, sport marketing, and facility management. The New Zealand Breakers have two multi-purpose facilities within Auckland where home basketball games can viably be staged. Growing ticket demand and the opportunities associated with the larger and more modern of the two facility options have necessitated strategic thinking and decision making from Breakers’ management. They have not yet made a permanent move, but have chosen instead to move to the new facility gradually. There are several aspects of the ongoing transition period that require careful management to ensure the long-term success of the franchise. The Breakers’ management of the ongoing decision and transition are well-grounded in management, marketing, and facility management literature. As students consider the case, they will have the opportunity to think critically and consider theory in the context of a real professional sport franchise. A variety of questions and references are provided in the teaching note that can be used in conjunction with the implementation of the case study. 相似文献
