The use of physical performance-enhancing drugs is not limited to professional sports only, but has also been reported as common practice in recreational sports. A significant amount of epidemiological studies have highlighted the collective of fitness center visitors to be a high-risk group for using performance-enhancing drugs. From a sociological perspective, however, the decision to use performance-enhancing drugs (e.g., doping in the context of high-performance sport) is not an individual phenomenon only, but rather a result of social opportunity structures. This research article gives insight into enhancing-related Internet forums, in which the expertise of using and applying substances is passed on step by step. Using selected criminological learning theories, the “doping talk” in these social networks is hermeneutically reanalyzed and the Internet is exposed as a previously under-analyzed option for acquiring knowledge on the use of performance-enhancing drugs. This article shows that users of “doping platforms” are highly informed about doping and this offer of information acts like a knock-on effect to athletes who have so far abstained from doping. Consequently, future prevention models against the abuse of performance-enhancing drugs should consider the subcultural background of the milieu in which the athletes act. 相似文献

Establishing a requirement for, justifying public spending on, and evaluating the effectiveness of anti-doping policies all accentuate the need for reliable estimates of doping prevalence in sport. To date, despite considerable effort and much empirical research, this critical information is still not available. Methodological concerns that make doping epidemiology research difficult have been noted, and to some degree addressed in relation to under-reporting bias. In this paper, we use a simple game model to outline a potential responding behaviour among self-reporting athletes on the use of doping that could potentially invalidate any prevalence estimation arising from self-reports. We show a paradoxical situation in which a potential strategic behaviour inevitably leads to a game where the ‘lying’ is a dominant strategy for both doping users and non-users. A slightly more advanced look at the situation might possibly alter this seemingly absurd conclusion, however not in a direction offering any easy solutions for empirical doping research. Although we acknowledge that the proportions of respondents engaging in false telling are likely to vary across samples and differ between doping users and clean athletes, our simple model effectively draws attention to a neglected side of evasive responding in surveys. The response bias that potentially could lead to under- and over-reporting should be considered when self-reported prevalence rates are used to inform anti-doping prevention and intervention policies. Survey methodologies that are able to account for potential distortions would make a considerable contribution to doping research. 相似文献

Abstract Eleven elite kayakers performed an identical weekly training schedule each week during a 3-week training-camp. The Profile of Mood States (POMS) inventory (“right now” instructions) was completed before and after selected workouts each week to assess both training-induced mood disturbances and the extent of recovery following short and long rest. The ratio of POMS vigour to POMS fatigue scores was used as an “energy index”. Energy index scores were compared with ratings of perceived exertion (RPE) to address the size of the training load. Performance measures were obtained during the first and last week. The results showed that the energy index decreased (p<0.01) throughout the camp and did not return to initial values following either the short (one night) or long rest (two nights and one day). Performance measures and RPE remained unaffected throughout training, as did the POMS depression scores, indicating that the athletes experienced an overreached state but did not develop staleness. Our results suggest that repeated evaluation using POMS fatigue, vigour, and depression scores during periods of intensified training may help prevent athletes from becoming severely overreached and reduce the likelihood of staleness. 相似文献

Abstract This paper examines the influence of selected risk factors on injuries among male players of competition handball. Data relating to risk factors were collected using a self-report questionnaire. The factors that were examined were age, height, weight, body mass index, field position, past sport experience, level of competition, pre-season conditioning, number of practices per week, frequency of participation in games, use of prophylactic equipment, use of stretching exercises, and technical training. The questionnaire was administered to 216 male handball players. Nearly half of the players (42.6% or n=92) reported that they had been injured during the previous two years. The injury incidence was 8.14 injuries per 1,000 game hours for the preceding two years. Logistic regression analysis revealed that the variables “use of prophylactic equipment” and the “number of practices per week” contributed significantly to the prediction of an injury in handball players. The results of this study suggest that it is possible to reduce injury occurrence by giving specific attention to players using prophylactic equipment and to the lower-competition-level players. 相似文献

Abstract The primary purpose of this investigation was to determine the relative importance of the attributes that student–athletes use when determining their choice of a university. A second purpose was to compare previous athletic institutional choice studies with the results of this study to determine if the most important attributes were similar and to compare and contrast methodologies. Six hundred five Division I student–athletes (344 baseball players and 261 softball players) from all eight national geographic regions of the NCAA participated in this study. The experimental procedure was based on Information Integration Theory and a 210 fractional factorial design that resulted in 32 “choice sets.” These choice sets were composed of universities described by 10 attributes. This framework required that the student–athletes choose from among three university profiles, thereby realistically simulating the decision process. The results for the aggregate sample show that the “Amount of Scholarship” attribute was the most important factor in the institutional choice process. Many demographic variables were analyzed (sex, race, amount of scholarship received as a freshman, amount of perceived financial need, self-reported grade-point average, questionnaire completion procedures, in-state/out-of-state status, NCAA region, and rank in high school) in conjunction with the choice set data in a post-hoc framework. The results for a subset of these variables are reported in this paper; differences (in the order of importance of the attributes) were found among groups. A primary finding of this study is that a student–athlete's perceived financial need has a critical impact on the institutional choice process. A second important finding is that, although “Amount of Scholarship” was determined to be the most important attribute, this result stands in stark contrast to previous studies that have investigated the institutional choice process of student–athletes. 相似文献

To inform anti-doping policy and practice, it is important to understand the complexities of doping. The purpose of this study was to collate and systematically examine the reasoned decisions published by UK Anti-Doping for doping sanctions in rugby union in the UK since the introduction of the 2009 World Anti-Doping Code. Case files were content analysed to extract demographic information and details relating to the anti-doping rule violation (ADRV), including individuals’ explanations for how/why the ADRV occurred. Between 2009 and 2015, 49 rugby union players and one coach from across the UK were sanctioned. Over 50% of the cases involved players under the age of 25, competing at sub-elite levels. Reasons in defence of the ADRV focused on functional use and lifestyle factors rather than performance enhancement. An a priori assessment of the “need”, “risk” and “consequence” of using a substance was not commonplace; further strengthening calls for increasing the reach of anti-doping education. The findings also deconstruct the view that “doped” athletes are the same. Consequently, deepening understanding of the social and cultural conditions that encourage doping remains a priority. 相似文献

This study sought to establish perceptions of elite endurance athletes on the role and worth of altitude training. Elite British endurance runners were surveyed to identify the altitude and hypoxic training methods utilised, along with reasons for use, and any situational, cultural and behaviour factors influencing these. Prior to the 2012 Olympics Games, 39 athletes and 20 support staff (coaches/practitioners) completed an internet-based survey to establish differences between current practices and the accepted “best-practice”. Almost all of the athletes (98%) and support staff (95%) surveyed had utilised altitude and hypoxic training, or had advised it to athletes. 75% of athletes believed altitude and hypoxia to be a “very important” factor in their training regime, with 50% of support staff believing the same. Athletes and support staff were in agreement of the methods of altitude training utilised (i.e. 'hypoxic dose’ and strategy), with camps lasting 3–4 weeks at 1,500–2,500 m being the most popular. Athletes and support staff are utilising altitude and hypoxic training methods in a manner agreeing with research-based suggestions. The survey identified a number of specific challenges and priorities, which could provide scope to optimise future altitude training methods for endurance performance in these elite groups. 相似文献

The impact on women athletes of receiving or not receiving scholarships was investigated in this study. The subjects were 61 women participating in 10 intercollegiate sports. Attitudes were assessed by administering a questionnaire prior to, and after, scholarships had been awarded. The questionnaire items were grouped into three subsets which reflected different attitudes about the “impact” of awarding athletic scholarships. A 4 × 2 × 2 repeated measures design was used to test for significant statistical interaction between the three independent variables: (a) wanting a scholarship, (b) receiving a scholarship, and (c) reacting to the awarding of scholarships. 相似文献

The study examined developmental participation patterns of international top athletes. Pairs of 83 international medallists (including 38 Olympic/World Champions) and 83 non-medallists were matched by sport, age and gender. A questionnaire recorded their volume of organised (coach-led) practice/training in their respective main sport and in other sports through childhood, adolescence and adulthood, and also involvement in non-organised (peer-led) sport activity. Analyses revealed that the medallists started practice/training in their main sport at an older age than non-medallists and accumulated slightly, but significantly less main-sport practice/training through childhood/adolescence. But they participated in more practice/training in other sports, particularly before entering their main sport. The medallists also maintained engagement in other sports over more years and specialised later than the non-medallists. Other sports engaged in were mostly unrelated to an athlete’s main sport. The results were robust across different types of sports. The observations are reflected against tenets of the “deliberate practice” and “Developmental Model of Sport Participation” frameworks. Early diversified practice and learning experiences are discussed relative to the expansion of youngsters’ potential for future long-term learning. In elite athletes, interaction of sport-specific practice/training with early other-sports participation mostly facilitates long-term attainment of international senior medals. 相似文献

Recent theory and research suggest that perfectionism is a personal factor contributing to athletes’ vulnerability to doping (using banned substances/drugs to enhance sporting performance). So far, however, no study has examined what aspects of perfectionism suggest a vulnerability in junior athletes. Employing a cross-sectional design, this study examined perfectionism and attitudes towards doping in 129 male junior athletes (mean age 17.3 years) differentiating four aspects of perfectionism: perfectionistic strivings, perfectionistic concerns, parental pressure to be perfect, and coach pressure to be perfect. In the bivariate correlations, only parental pressure showed a positive relationship with positive doping attitudes. In a multiple regression analysis controlling for the overlap between the four aspects, perfectionistic strivings additionally showed a negative relationship. Moreover, a structural equation model examining the relationships between all variables suggested that coach pressure had a negative indirect effect on attitudes towards doping via perfectionistic strivings. The findings indicate that perceived parental pressure to be perfect may be a factor contributing to junior athletes’ vulnerability to doping, whereas perfectionistic strivings may be a protective factor. 相似文献

Abstract We report the initial validation of a multi-component assessment model for monitoring training distress among athletes. The model combines measures of mood disturbance with measures of perceived stress and symptom intensity. Altogether, 492 athletes completed the 10-item Perceived Stress Scale (PSS-10; Cohen et al., 1983), the 24-item Brunel Mood Scale (BRUMS; Terry et al., 2003), and a checklist of 19 symptoms associated with acute overtraining (Fry et al., 1994). Six training distress factors were identified by an exploratory factor analysis: “depressed mood”, “perceived vigour”, “physical symptoms”, “sleep disturbance”, “perceived stress”, and “general fatigue”. Comparisons of group means of these factors with a previously validated inventory were consistent with theoretical predictions and provided evidence of construct validity. Internal consistency of the subscales was also confirmed, with Cronbach alphas ranging from 0.72 to 0.86. Together, these findings suggest that this multi-component model provides a sound conceptual basis for the assessment of training distress among athletes. 相似文献

The aim of this study was to examine: 1) whether sport supplement use is related to doping and 2) whether sport supplement beliefs mediated this relationship. In Study 1, athletes (N = 598), completed measures of sport supplement use, sport supplement beliefs, and doping attitudes. In Study 2, athletes (N = 475) completed measures of sport supplement use, sport supplement beliefs, and doping likelihood. In both studies, sport supplement use predicted doping outcomes indirectly via sport supplement beliefs. Our findings provide novel evidence to suggest that sport supplement users, who strongly believe that sport supplements are effective, are more likely to dope. For anti-doping organisations wishing to prevent doping, targeting an athlete’s beliefs about sport supplements may improve the effectiveness of anti-doping prevention programmes. 相似文献

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes. 相似文献

Given the concern over doping in sport, researchers have begun to explore the role played by self-regulatory processes in the decision whether to use banned performance-enhancing substances. Grounded on Bandura’s (1991) theory of moral thought and action, this study examined the role of self-regulatory efficacy, moral disengagement and anticipated guilt on the likelihood to use a banned substance among college athletes. Doping self-regulatory efficacy was associated with doping likelihood both directly (b = ?.16, P < .001) and indirectly (b = ?.29, P < .001) through doping moral disengagement. Moral disengagement also contributed directly to higher doping likelihood and lower anticipated guilt about doping, which was associated with higher doping likelihood. Overall, the present findings provide evidence to support a model of doping based on Bandura’s social cognitive theory of moral thought and action, in which self-regulatory efficacy influences the likelihood to use banned performance-enhancing substances both directly and indirectly via moral disengagement. 相似文献

In a group-serve-reception task, how does serve-reception become effective? We addressed “who” receives/passes the ball, what task-related variables predict action mode selection and whether the action mode selected was associated with reception efficacy. In 182 serve-receptions we tracked the ball and the receivers’ heads with two video-cameras to generate 3D world-coordinates reconstructions. We defined receivers’ reception-areas based on Voronoi diagrams (VD). Our analyses of the data showed that this approach was accurate in describing “who” receives the serve in 95.05% of the times. To predict action mode selection, we used variables related to: serve kinematics, receiver’s movement and on-court positioning, the relation between receiver and his closest partner, and interactions between receiver-ball and receiver-target. Serve’s higher initial velocities together with higher maximum height, as well as smaller longitudinal distances between receiver and target increased the chances for the use of the overhand pass. Conversely, decreasing alignment of the receiver with the ball and the target increased the chances of using the underhand-lateral pass. Finally, the use of the underhand-lateral pass was associated with lower quality receptions. Behavioural variability’s relevance for serve-reception training is discussed. 相似文献
