通过对NBA常规赛中锋球员的身高、体重以及各项常规技术统计数据的研究分析,发现:虽然身高与体重是篮球运动中球员的重要指标,但是,身高和体重与中锋球员大多数技术统计数据并不成正比。篮球中锋运动员在选材时不能一味的追求身体高度和体重,应充分考虑到身高体重以外的其他因素(篮球意识、灵活度等等),进行综合分析。 相似文献

A growing body of academic and popular literature considers the history of South African football. These and existing publications pay little or no attention to the emergence of white professional football in apartheid South Africa. The National Football League (NFL) challenged the amateur game and introduced professional football to the country. During its 17-year existence, the NFL grew each season with large attendances until its demise in 1977. In addition, the NFL imported a range of international players, invited foreign teams and actively engaged in the political debates in South African sport at the time. The NFL was instrumental in popularising the game across the country for all South Africans. The NFL became the most popular sports entertainment of choice for South Africans during this period. Finally, the NFL actively engaged in a campaign of destroying rival non-racial anti-apartheid leagues while simultaneously co-opting less progressive organisations. 相似文献

During the 1970s, a number of prominent British and Irish footballers – the likes of which included Gordon Banks, George Best, Bobby Charlton, Geoff Hurst and Bobby Moore – played as ‘guest players’ on a short-term basis for various clubs in South Africa's National Football League (NFL), a ‘whites-only’ professional league that spanned the period 1959–1977. Coupled with this, NFL clubs from the outset also secured the services of additional foreign players of lesser standing on longer term contracts in an attempt to improve the standard of play. The strategy of importing high-profile ‘guests’ during the 1970s ultimately proved unsuccessful in sustaining the league as it disbanded after the 1977 season. Utilising archival documentation, contemporary media reports and existing football works, this essay aims to establish the reasons behind the NFL's demise. Two particular factors under consideration are the erosion of the league's entertainment value and the deteriorating economic conditions within South Africa at the time. These elements are juxtaposed with additional factors such as the rise in popularity of multiracial football, the resulting drain of sponsorship away from the white professional game, as well as political machinations within South Africa during this period. 相似文献

Purpose: The purpose of this study was to determine magnitudes of differences for anthropometric and athletic performance scores between high school and elite college-level American football players. Method: Participants included high school-age (n = 3,666) athletes who participated in American football combines, as well as elite college-level (n = 5,537) athletes who participated in the National Football League (NFL) scouting combine. Combine data included position; height; weight; 10-, 20-, and 40-yard dash; pro-agility (PA); L-cone drill (LC); vertical jump (VJ); and broad jump (BJ). Athletes were separated into their respective position group, defensive back (DB), wide receiver (WR), linebacker (LB), quarterback (QB), running back (RB), tight end (TE), defensive line (DL), and offensive line (OL) for analysis of performance differences. Percent differences for each dependent variable were calculated to quantify magnitudes of differences. Results: NFL combine participants scored 3% to 25% better on all measurements, with the largest differences between weight and VJ (14%–25%). Conclusion: The largest measurement-specific differences between high school-age and elite college-level American football players were body size and power. Although it may seem intuitive that elite college-level players would perform better, these data provide a unique perspective to high school players, parents, and coaches, giving new information to use when designing measurement-specific athletic development programs. Thus, strength and conditioning professionals may benefit from emphasizing increases in muscle mass and power output in strength and conditioning programs. 相似文献

On November 6, 1995, Art Modell announced his intention to relocate the National Football League's (NFL) Cleveland Browns to Baltimore following the season. After 4 months of civic activism from Cleveland's community and legal action from the city's politicians, Cleveland, the NFL and Modell agreed to a deal that allowed the long-time owner to honour his contract with Baltimore and simultaneously provided a NFL club to Cleveland to begin play in 1999. This settlement was unique because it allowed Cleveland to retain the naming rights, colours, logo and, most significantly, the history of the Browns. Media presentations of Modell's announcement during the 4-month period illuminated a complex symbiotic relationship between the press, the public and sports entrepreneurs. The local media castigated and vilified Modell for betraying Cleveland's community and disturbing the city's supposed ‘renaissance’, while the national media connected with Cleveland as a leading member of the dilapidated ‘Rustbelt’ in the new American economy. These interconnections led fans, followers and other pundits of the NFL to question the actions of football entrepreneurs and provided a platform at the turn-of-the twenty-first century for sustained criticism of the business of professional sports, franchise relocation and the widening social class divide in the NFL. 相似文献

The aims of this study were to (1) investigate the influence of general anthropometric variables, handball-specific anthropometric variables, and upper-limb power and strength on ball-throwing velocity in a standing position (ν(ball)), and (2) predict this velocity using multiple regression methods. Forty-two skilled male handball players (age 21.0?±?3.0 years; height?=?1.81?±?0.07?m; body mass?=?78.3?±?11.3?kg) participated in the study. We measured general anthropometric variables (height, body mass, lean mass, body mass index) and handball-specific anthropometric parameters (hand size, arm span). Upper-limb dynamic strength was assessed using a medicine ball (2?kg) throwing test, and power using a one-repetition maximum bench-press test. All the variables studied were correlated with ball velocity. Medicine ball throwing performance was the best predictor (r?=?0.80). General anthropometric variables were better predictors (r?=?0.55-0.70) than handball-specific anthropometric variables (r?=?0.35-0.51). The best multiple regression model accounted for 74% of the total variance and included body mass, medicine ball throwing performance, and power output in the 20-kg bench press. The equation formulated could help trainers, athletes, and professionals detect future talent and test athletes' current fitness. 相似文献

Abstract Recent data indicate that levels of overweight and obesity are increasing at an alarming rate throughout the world. At a population level (and commonly to assess individual health risk), the prevalence of overweight and obesity is calculated using cut-offs of the Body Mass Index (BMI) derived from height and weight. Similarly, the BMI is also used to classify individuals and to provide a notional indication of potential health risk. It is likely that epidemiologic surveys that are reliant on BMI as a measure of adiposity will overestimate the number of individuals in the overweight (and slightly obese) categories. This tendency to misclassify individuals may be more pronounced in athletic populations or groups in which the proportion of more active individuals is higher. This differential is most pronounced in sports where it is advantageous to have a high BMI (but not necessarily high fatness). To illustrate this point we calculated the BMIs of international professional rugby players from the four teams involved in the semi-finals of the 2003 Rugby Union World Cup. According to the World Health Organisation (WHO) cut-offs for BMI, approximately 65% of the players were classified as overweight and approximately 25% as obese. These findings demonstrate that a high BMI is commonplace (and a potentially desirable attribute for sport performance) in professional rugby players. An unanswered question is what proportion of the wider population, classified as overweight (or obese) according to the BMI, is misclassified according to both fatness and health risk? It is evident that being overweight should not be an obstacle to a physically active lifestyle. Similarly, a reliance on BMI alone may misclassify a number of individuals who might otherwise have been automatically considered fat and/or unfit. 相似文献

When "where" is more important than "when": birthplace and birthdate effects on the achievement of sporting expertise 总被引：3，自引：2，他引：1
In this study, we assessed whether contextual factors related to where or when an athlete is born influence their likelihood of playing professional sport. The birthplace and birth month of all American players in the National Hockey League, National Basketball Association, Major League Baseball, and Professional Golfer's Association, and all Canadian players in the National Hockey League were collected from official websites. Monte Carlo simulations were used to verify if the birthplace of these professional athletes deviated in any systematic way from the official census population distribution, and chi-square analyses were conducted to determine whether the players' birth months were evenly distributed throughout the year. Results showed a birthplace bias towards smaller cities, with professional athletes being over-represented in cities of less than 500,000 and under-represented in cities of 500,000 and over. A birth month/relative age effect (in the form of a distinct bias towards elite athletes being relatively older than their peers) was found for hockey and baseball but not for basketball and golf. Comparative analyses suggested that contextual factors associated with place of birth contribute more influentially to the achievement of an elite level of sport performance than does relative age and that these factors are essentially independent in their influences on expertise development. 相似文献

The aim of the present study was to identify whether the relative shape and size characteristics of elite male tennis players have changed over time, and in addition whether any anthropometric parameters characterise the more successful players in Grand Slam tournaments. The height and body mass of the players qualifying for the first round in all four Grand Slam tennis tournaments during the period 1982–2011 was obtained, and successful players defined arbitrarily as those reaching round 3 or beyond. Body mass index (BMI) and the reciprocal ponderal index (RPI) were used as our measures of body shape. Multilevel modelling was used to explore the trend over time using non-linear polynomials. The results suggest that the body shape of elite tennis players has changed over time, with a non-linear (cubic polynomial regression model) increase in BMI and a similar non-linear decline in the RPI. BMI, reflecting greater muscle mass rather than greater adiposity, has emerged as an important factor associated with success, identified by a significantly positive (steeper) “successful player”-by-“year” interaction term. The evidence that the RPI of elite tennis players has also decreased over time, together with a significantly negative “successful player”-by-“year” interaction term, suggests that a more linear (ectomorphic) body shape is a less important factor in terms of success. These results suggest that elite male tennis players are becoming more power trained athletes as opposed to endurance athletes, with greater muscle mass being an important factor associated with success in all Grand Slam tournaments. 相似文献

The emergence of Pacific Island (PI) ethnicities in the National Rugby League (NRL) over the past 18 years is widely acknowledged. At present, participants who have PI or Maori heritage represent 38% of the NRL's senior roster plus 37% at the National Youth Competition (NYC) level. This paper will examine the complex personal and ethnic biographies, and the process through which these athletes create their identities as a minority group within the culture of professional rugby league. In particular, the theoretical concept of ethnic persistence provides a way to understand the identity formation of PI athletes currently in the NRL. Rather than being assimilated into Western culture, the cultural discourses that are inextricably linked to ethnic PI identities are crucial to understanding the experiences of footballers in the NRL. The experiences of the footballers, characterised by a lack of understanding and acknowledgement of PI traditions, suggest that national identities, rivalries and conflict that have shaped the history of these island nations are overridden in favour of common traits, experiences and heritage. 相似文献

The initial steps of a sprint are important in team sports, such as rugby, where there is an inherent requirement to maximally accelerate over short distances. Current understanding of sprint acceleration technique is primarily based on data from track and field sprinters, although whether this information is transferable to athletes such as rugby players is unclear, due to differing ecological constraints. Sagittal plane video data were collected (240?Hz) and manually digitised to calculate the kinematics of professional rugby forwards (n?=?15) and backs (n?=?15), and sprinters (n?=?18; 100?m personal best range?=?9.96–11.33?s) during the first three steps of three maximal sprint accelerations. Using a between-group research design, differences between groups were determined using magnitude-based inferences, and within-group relationships between technique variables and initial sprint acceleration performance were established using correlation. Substantial between-group differences were observed in multiple variables. Only one variable, toe-off distance, differed between groups (d?=??0.42 to ?2.62) and also demonstrated meaningful relationships with sprint performance within all three groups (r?=??0.44 to ?0.58), whereby a stance foot position more posterior relative to the centre of mass at toe-off was associated with better sprint performance. While toe-off distance appears to be an important technical feature for sprint acceleration performance in both sprinters and rugby players, caution should be applied to the direct transfer of other kinematic information from sprinters to inform the technical development of acceleration in team sports athletes. 相似文献

The aim of this study was to compare the somatotype and size of elite female basketball players in terms of playing position and team performance. Anthropometry and somatotype data were collected on 168 players from 14 countries before the Women's World Basketball Championship, Australia, 1994. There were 64 guards (mean?±?s: age 25.4?±?3.3 years, height 1.72?±?0.06?m, mass 66.1?±?6.2?kg, somatotype?=?2.9?–?3.9?–?2.6), 57 forwards (age 25.2?±?3.8 years, height 1.81?±?0.06?m, mass 73.3?±?5.9?kg, somatotype?=?2.8?–?3.5?–?3.2) and 47 centres (age 24.1?±?3.1 years, height 1.90?±?0.06?m, mass 82.6?±?8.2?kg, somatotype?=?3.2?–?3.1?–?3.4). Mean somatotypes by position were significantly different (F?=?7.73, P?<?0.01). Guards had greater mesomorphy than centres and less ectomorphy than forwards and centres. When discriminant function analysis was applied to endomorphy, mesomorphy, ectomorphy, age, height and mass, only height, mass and ectomorphy entered (Wilks' λ?=?0.351, F?=?31.40, P?<?0.000), 70% of the variance was accounted for, and 72% of players were correctly classified. In the four top versus four bottom teams, guards were taller and more ectomorphic, forwards were taller, with lower mesomorphy and higher ectomorphy, and centres did not differ. Thus there are some differences in somatotypes by position and team placing, but the combination of height, mass and ectomorphy provide the best differentiation by position. 相似文献

This study aimed to evaluate the possibility that differences in sensorimotor abilities exist between hitters and pitchers in a large cohort of baseball players of varying levels of experience. Secondary data analysis was performed on 9 sensorimotor tasks comprising the Nike Sensory Station assessment battery. Bayesian hierarchical regression modelling was applied to test for differences between pitchers and hitters in data from 566 baseball players (112 high school, 85 college, 369 professional) collected at 20 testing centres. Explanatory variables including height, handedness, eye dominance, concussion history, and player position were modelled along with age curves using basis regression splines. Regression analyses revealed better performance for hitters relative to pitchers at the professional level in the visual clarity and depth perception tasks, but these differences did not exist at the high school or college levels. No significant differences were observed in the other 7 measures of sensorimotor capabilities included in the test battery, and no systematic biases were found between the testing centres. These findings, indicating that professional-level hitters have better visual acuity and depth perception than professional-level pitchers, affirm the notion that highly experienced athletes have differing perceptual skills. Findings are discussed in relation to deliberate practice theory. 相似文献
