Currently in the literature, there is a dearth of empirical research that confirms whether international junior success is a reliable predictor for future international senior success. Despite the uncertainty of the junior–senior relationship, federations and coaches still tend to use junior success as a predictor for long-term senior success. A range of former investigations utilising a retrospective lens has merely focused on success that athletes attained at junior level competitions. Success that was achieved at senior-level competitions but at a junior age was relatively ignored. This study explored to what extent international senior success can be predicted based on success that athletes achieved in either international junior level competitions (i.e. junior medalists) or senior competitions at a junior age (i.e. early achievers). The sample contains 4011 international male and female athletes from three combat sports (taekwondo, wrestling and boxing), who were born between 1974 and 1990 and participated in both international junior and senior-level competitions between 1990 and 2016. Gender and sport differences were compared. The results revealed that 61.4% of the junior medalists and 90.4% of the early achievers went on to win international medals at a senior age. Among the early achievers, 92.2% of the taekwondo athletes, 68.4% of the wrestling athletes and 37.9% of the boxing athletes could be reliably “predicted” to win international senior medals. The findings demonstrate that specific to the three combat sports examined, international junior success appears to be an important predictor to long-term international senior success.  相似文献

Abstract

The present study investigated the role of chronic sport participation in the modulation of vigilance and inhibitory control. We also aimed to disentangle the relative contribution of different types of sport expertise and sport-related fitness to the exercise-cognition relationship. Three groups of young adults differing in their chronic sport expertise (externally-paced sports, n?=?22, self-paced sports, n?=?22, non-athletes, n?=?22) took part in the study. Participants completed a cardiovascular fitness test, a hand-eye coordination test and two different types of vigilance tasks: (1) Psychomotor Vigilance Task (PVT) and (2) Oddball Task, which were designed to gain insight into the cognitive processes involved in sustaining attention over time and allocating selective attention by exerting inhibitory control, respectively. No differences were found in PVT performance between the two athlete groups and between self-paced sports athletes and non-athletes, whereas athletes from externally-paced sports outperformed non-athletes. Crucially, athletes from externally-paced sports also differed from those of self-paced sports and non-athletes in the Oddball task, showing less omission and commission errors. The sport expertise effect was independent of participant’s cardiovascular fitness while hand-eye coordination modulated vigilance and inhibitory control performance. Our findings add novel empirical evidence to the role of expertise in cognitively demanding sports as an important factor in the relationship between exercise and cognition.  相似文献

In many competitive sports, the use of a cut-off date for junior competition has been associated with a skewed birth date distribution in junior and senior players. The International Tennis Federation uses a junior competition year that commences on 1 January. The purpose of the current investigation was to describe the birth date distribution of 448 elite senior tennis players and 476 elite junior tennis players. There was a significant season of birth bias among elite senior players (P <?0.001), with 58.9% being born in the first 6 months of the year. There was also a significant season of birth bias among elite junior players (P <?0.001), with 59.5% being born in the first 6 months of the year. This pattern was observed in both male and female players as well as in players from different regions. The results provide evidence that it is the cut-off date for the junior competition year that is responsible for the skewed birth date distribution in tennis rather than regional or climatic factors.  相似文献

Elite track and field athletes with greater and lesser multi-year performance improvement were compared regarding their developmental sport-specific and non-specific, organised (coach-led) and non-organised (peer-led) sporting activities. Athlete pairs were matched on gender, discipline and baseline performance in competitions (at 13/19 years). Their unequal subsequent performance development during junior (13–17 years; n = 138) and senior (19–23+ years; n = 80) age ranges defined “strong responders” and “weak responders”. Analyses revealed that junior-age strong responders accumulated more organised practice in athletics than weak responders, while the amounts of all other types of activities were indifferent. Senior-age strong responders did not accumulate a greater total sum of all kinds of sport activities or greater amounts of organised practice in athletics or non-organised involvement in athletics or other sports than weak responders. But they engaged in more organised practice and competitions in other sports over more years (9 vs. 2 years) and specialised in athletics at a later age than weak responders (16 vs. 11 years). The results were also robust among senior international medallists vs. national medallists. The findings are reflected relative to the hypotheses of “multiple sampling and functional matching”, “learning transfer as preparation for future learning” and “authenticity of variable learning experiences”.  相似文献

This study evaluated whether exposing junior netball players to greater amounts of competition relevant activity (playing form activity) had an effect on game play outcomes and session involvement. A group-randomised controlled trial in one junior netball club in the Hunter Region, NSW, Australia. Ninety female athletes (mean age = 9.04 years, SD 1.53) were randomised by team (n = 11) into the intervention (n = 41) or 9-week wait-list control (n = 49) condition. The Professional Learning for Understanding Games Education into Sport (PLUNGE into Sport) programme was undertaken in the first half of nine training sessions (9 × 30 min). The intervention exposed athletes to playing form activity through a coach development programme within training sessions. Athletes’ decision-making, support and skill outcomes during a small-sided invasion game, and session involvement (pedometer step/min), were measured at baseline and 9-week follow-up. Linear mixed models revealed significant group-by-time intervention effects (P < 0.05) for decision-making (d = 0.4) and support (d = 0.5) during game play, and in-session activity (d = 1.2). An intervention exposing athletes to greater levels of playing form activity, delivered via a coach education programme, was efficacious in improving athlete decision-making and support skills in game play and increasing athlete involvement during sessions.  相似文献

ABSTRACT

The aim of the present study was to determine the factors affecting sports involvement in a school-based adolescent population. The cross-sectional cohort study assessed anthropometry, physical capacities and motor competence in 501 boys (aged 10–16 y), from junior (10–12 y) and senior (13–16 y) cohorts. Sports participation data was collected from junior participants. Multivariate analysis of covariance revealed moderate maturity, anthropometry, physical capacity and motor competence differences between sports in the senior cohort (F = 2.616, p < 0.001, η2 = .08), but not in the junior cohort. Furthermore, differences in physical fitness were revealed between playing levels (F = 2.616, p < 0.001, η2 = .08), with a discriminant analysis correctly classifying 73% of participants using aerobic fitness and vertical jump measures. Representative level participants engaged in more structured training and commenced organised competition at a later age (F = 4.332, p < 0.001, η2 = .21). This study’s findings are twofold: 1) physical and motor competence profiles differ more between sports with increasing age, and 2) participants at a higher level of competition report delayed engagement in their main sport. As a result, schools may be the ideal environment in which to provide children and adolescents with the opportunity to sample different sports.  相似文献

Abstract

The purpose of this initial predictive validity study was to determine the ability of measures derived from the Athletes' Perceptions of Coaching Competency Scale II – High School Teams (APCCS II-HST) to predict satisfaction with the head coach. Specification of the statistical model was informed by the mediational model of coach–athlete interactions. The technical quality of the satisfaction measure was evaluated before testing the predictive validity of the coaching competency measures. Data were collected from athletes of seven sports. Athlete observations (N = 748) were clustered within teams (G = 74). Multi-group confirmatory factor analyses (CFA) provided evidence for factorial invariance of a reduced version of the satisfaction measure by athlete gender. Multi-level CFA provided evidence of model–data consistency for a reduced version of the satisfaction measure. Multi-level structural equation modelling provided evidence for the ability of latent coaching competency to positively predict latent satisfaction at both the athlete level (technique competency and motivation competency) and the team level (coaching competency) and for close model–data fit. Implications of this study include: that the APCCS II-HST should be viewed as a replacement for the Coaching Competency Scale when the intended population is appropriate; a preliminary multi-level measurement model for satisfaction with one's coach that should be considered as a potential starting point in subsequent studies; and empirical support for a key relationship proposed in the mediational model of coach–athlete interactions.  相似文献

随着体育运动的发展和人们对其问题的重视程度的加大,基层体育的发展也开始不断地被人们所关注,但我们也清楚地看到我们的高水平运动员大多是在初中后半段或者是高中阶段开始发展,并在短时间内挖掘其潜能而得来的。短时期内的训练尽管是系统的训练并让其达到较高的水平,但在对运动员潜力的挖掘上是不够的,也是不科学的,所以我们的运动员在进入高一级学校进行深造时,其可塑性便大大降低了。随着科学的日益发展,训练方法的更加科学化、系统化、客观化,要创造出优异的成绩,科学地进行选材尤其是运动员初级阶段的科学选材便显示出了无比重要的作用。  相似文献

Placebo-induced performance enhancement is a new controversial issue in competitive sports. Coaches have control over the use of placebos, but their practices and attitudes were barely studied to date. In this survey 96 coaches from regional, national and international levels were asked about their practices and attitudes concerning placebo use in sports. Results revealed that 90% of the respondents were aware of placebo effects. Many (44%) coaches admitted to administering a placebo to their athletes. Those working at international level have administered placebos more often than the others (P = .02). Two thirds of the coaches agreed to the wider use of placebos in sport. Respondents who have used placebos in the past reported improved athletic performance. They also agreed more to the wider use of placebos than the coaches who previously did not use a placebo (P = .001). Team sport coaches use more often placebos than coaches working with individual athletes (P = .05). Only 10% of the sample thought that their athletes would refuse a hypothetical performance enhancer supplied by them. After a successful placebo intervention, only 15% of the coaches would administer it again without consulting the athlete. Overall, the coaches are optimistic about placebo use in sports. Close to half of them, especially those coaching at higher levels of competition, may use it regularly while achieving positive results.  相似文献

Abstract

The development of peak performances is a main research focus in sports science. It is unclear how many former top junior athletes achieve success in the elite class later. The aim of the present study was to examine the careers of athletes who participated in major junior or adult/elite cycling events using prospective and retrospective analysis of competition results. The official results of major junior (age ≤ 18 years) and elite (age > 18 years) cycling races from 1980 to 2004 were analysed. Age-related aspects, career lengths, and success were compared between riders who presented results in both junior and elite races (JUNIOR ELITE) and riders who had no junior race results (ELITE ONLY). Altogether, 27,454 results of 8004 athletes from 108 countries were collected. We found that 29.4% of the elite athletes had participated in junior World Championships, and that 34% of the participants in junior World Championships later participated in major elite competitions. JUNIOR ELITE athletes are significantly more successful in several cycling disciplines and have their first and last elite result at a younger age than ELITE ONLY athletes. No difference was found in career lengths. The data presented here emphasize the importance of long-term training programmes in the development of peak performance in cycling.  相似文献

Abstract

This study described and compared the personality and background of women participating in intercollegiate sports competition. Personal feelings about competition and faculty adviser estimation of personality were also described. The Cattell 16 PF test of personality and a personal information questionnaire were administered. This investigation involved four groups of junior or senior college women athletes: 15 individual, 16 subjectively-judged, 28 team, and 18 team-individual sports participants. Each subject was required to have competed in her sport for at least two seasons. A group of 42 nonparticipants was also studied. The subjects were selected from the five largest state universities in Ohio. Results indicated groups were similar on 14 dimensions of personality and significantly different on 9. The individual and subjectively-judged were more alike and also more similar to the nonparticipants than to the other two groups. The team and team-individual groups tended to be alike and dissimilar to the other three groups. Faculty advisers significantly misjudged the personality of their participants, with the team sports advisers being the most inaccurate. Questionnaire information indicated differences in socioeconomic background as well as personal feelings about competition.  相似文献

Abstract

The purpose of the study was to examine of the representation of women athletes during the 2015 FIFA Women’s World Cup. More specifically, we examined how individuals used various event-related hashtags (ie #SheBelieves and #FIFAWWC) on Instagram during the 2015 FIFA Women’s World Cup to frame identity, and challenge or reinforce gender stereotypes from the bottom-up. A content analysis of athlete photos containing #FIFAWWC (n = 706) and athlete photos containing #SheBelieves (n = 629) revealed that users primarily portrayed women athletes as athletically competent. Specifically, nearly 90% of Instagram posts containing either #FIFAWWC or #SheBelieves portrayed athletes in either athletic action or preparing for athletic action. These findings demonstrate that social media provide an opportunity to challenge gender stereotypes in women’s sports and thereby illustrate that social media users are willing to create their own frames around women athletes.  相似文献

Modern sports management necessitates the use of disciplinary systems to both dissuade and to penalise athletes who engage in off-field misconduct. Athlete misconduct threatens the financial viability of a club or sport, team morale and the image of the sport in the eyes of the public. Domestic Tribunals or penalisation through a Chief Executive Officer are the most commonly utilised methods for dealing with athlete misconduct. Each method concerns the law of contract to involve certain legal rights and risks. This article examines both methods with a view to informing sports officials of the legal rights and risks associated with the penalisation of athletes for offences of off-field misconduct.  相似文献

ABSTRACT

Limited research has examined the contributions of sport-specific family relationship problems to athlete mental health. In the current study we examined the extent to which collegiate athletes’ family problems (as measured by the Student Athlete Relationship Instrument factors, SARI) predict athletes’ general mental health distress and specific mental health symptoms that are relatively common in athletes (i.e. depression, anxiety, and drug and alcohol use). The study included 85 collegiate athletes (intramural, n?=?26; club sport, n?=?12; NCAA Division I, n?=?47). We hypothesized that both general mental health distress and commonly evidenced mental health symptoms would be predicted by athletes’ responses to the SARI factors (Poor Relationship and Lack of Support, General Pressure, Pressure to Quit or Continue Unsafely, Embarrassing Comments, and Negative Attitude). Results indicated that all of the aforementioned SARI factors predicted athletes’ ratings of depression and general mental health distress levels. Only the General Pressure SARI factor predicted athletes’ anxiety and drug use. Alcohol use was not predicted by any of the SARI factors. Receiver operating characteristic (ROC) analyses indicated that sport-specific problems in family relationships provided a good classification of athletes at risk for general mental health distress, depression, and anxiety. Practice implications are discussed in light of the results.  相似文献

Since the late 1800s, members of mainstream sport media have constructed narratives about American Indian athletes. Consistent with that history, American Indian athletes were featured in stories on sports television and in sports publications between November 1999 and July 2001, a time period that straddled the ending of the twentieth and beginning of the twenty-first centuries. This paper examines several of those stories, including an ESPN special on Native Americans in sport; the representation of Jim Thorpe in Athlete of the Century polls; the depiction of Ed ‘Wahoo’ McDaniel in Sports Illustrated; and the book A Season on the Reservation: My Sojourn With the White Mountain Apache by former Los Angeles Laker Kareem Abdul-Jabbar. The analysis reveals that racial dynamics and stereotypes about American Indians that exist broadly in US society are replicated and perpetuated in contemporary sport media narratives about American Indian athletes.  相似文献

ABSTRACT

Athlete adherence to nutritional guidance is critical for optimal health and performance, yet little is known about the barriers and enablers to athletes’ dietary behaviours within high-performance sport. To advance understanding, we applied a theoretical lens derived from the Capability, Opportunity, Motivation – Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to explore the qualitative accounts of sports nutritionists. Five focus groups comprising sports nutritionists working in Olympic and Paralympic sport (n = 14), professional sport (n = 6), or both (n = 6) were undertaken. Thematic analysis was conducted and the interpretations of the findings were guided by COM-B and the TDF. To achieve nutritional adherence, the behavioural analysis identified the need to intervene across all three COM-B components and at least five associated TDF domains (e.g., decision-making processes, reinforcement, social influences, behavioural regulation and environmental context and resource). For the first time, the findings illustrate the complex interplay of the training setting with the capabilities, opportunities, and motivation of the practitioners, athletes and coaches. By applying established behavioural science theories to sports nutrition, the foundations for the development of targeted and multifaceted behavioural interventions addressing athlete dietary adherence in high-performance sport have been laid.  相似文献
