ABSTRACTThe purpose of this study was to examine the variation in accumulated basketball training experience, body size, functional performance, deliberate practice motivation, achievement and competitiveness motivation and sources of enjoyment among young female basketball players, partitioning the potential variation by individuals´ biological characteristics (menarche status) and contextual characteristics (competitive age group and competitive level). We considered 114 adolescent female basketball players aged 14.3 (1.8) years. We used multilevel regression and poststratification estimations. The adolescent female basketball players selected for state-level had more accumulated experience, were taller and with better functional performance. Conditional on the data, youth female coaches tend to value (probably overvalue) size and function when selecting/promoting players, even at early age groups, likely contributing to an overrepresentation of early maturing girls in at early age groups. Players from club- and state-level were similarly highly motivated for deliberate practice and to achievement. Only for competitiveness, state-level players had higher values than club level players. The sources of enjoyment were influenced by context (competitive levels) for self-referenced competencies and others-referenced competencies. Structured programs of training and competition in youth female basketball provide a nurturing environment for the development of players´ engagement and commitment to training and excellence attainment. 相似文献

ABSTRACTThe purpose of the study was to assess (a) the prevalence of disordered eating (DE) in elite female team sports players compared to non-athletes and (b) to compare DE prevalence in elite female players in basketball, volleyball and water polo. One hundred and seventy-five females were recruited (age 23.10?±?5.4, BMI 21.85?±?2.3?kg/m2), 53 were elite basketball players, 42 were elite volleyball players, 34 were elite water polo players and 46 were non-athletes. Participants completed the Eating Disorders Questionnaire (EDE-Q) and a physical activity questionnaire. The EDE-Q incorporates 36 statements which relate to the occurrence and frequency of key behaviours of eating disorders, under the following four subscales: Restraint, eating concern, shape concern and weight concern and a global score of disordered eating. No differences were found in the EDE-Q subscale score and global score between athletes and non-athletes. Only 6.2% of the total number of participants exhibited DE using the global score >2.3. Water polo players had significantly higher scores in the ‘eating concern’ subscale and in the frequency of key behavioural features of DE such as binge eating episodes and objective and subjective bulimic episodes, compared to volleyball and basketball players. In conclusion, team sport elite female players do not exhibit greater prevalence of DE compared to non-athletes. Water polo, a sport that emphasises leanness and control of body weight for international distinctions, is associated with a higher tendency to exhibit DE, when compared to other team sports. 相似文献

The functional classification system for wheelchair basketball is based on an analysis of the players' functional resources through field-testing and game observation. Under this system, players are assigned a score of 1 to 4.5. The aim of this study was to determine if the wheelchair basketball player classification system reflects the existing differences in performance of elite female players. During the World Championship for Wheelchair Basketball in Sydney 1998, eight teams were videotaped for three 40-min games for a total of 120 min per team. Fifty-nine female players (Class I [1 and 1.5 points] n=12; Class II [2 and 2.5 points] n=20; Class III [3 and 3.5 points] n=13; Class IV [4 and 4.5 points] n=14) were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Two-way analysis of variance showed high point players to perform better compared with low point players for the majority of variables determining the quality of game performance. A lack of significant differences between two adjacent classes was explained on the basis of the methodological approach, the class-position relationship in this sample, and the performance level of women's wheelchair basketball. We conclude that the performance of elite female wheelchair basketball players is dependent on functional ability. 相似文献

Salivary cortisol, androstenedione delta 4, and dehydroepiandrosterone (DHEA) in 20 elite sportswomen were measured using radioimmunoassay in samples taken 5 min before and after a handball or volleyball competition. Three psychometric tests--State Trait Anxiety Inventory, Bortner, and Questionnaire de Personnalité pour Sportifs (questionnaire of personality for sports participants)--were used to evaluate the participants' personalities. Results indicated higher concentrations of cortisol and lower concentrations of delta 4 and DHEA in handball players before and after the competition. Cortisol values increased significantly during the competition in both groups. No changes were observed in androgen levels. The state of anxiety was higher in handball players, characterized by Pattern A behavior, whereas Pattern B behavior defined the volleyball players. The results suggest that adrenocortical changes during handball and volleyball competition are influenced by the different energy systems required by the two activities, individual personality characteristics, and the athlete's anxiety level relative to winning or losing. 相似文献

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30–15.07) and sex (female) (OR 4.62, 90% CI 1.15–18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage. 相似文献

AbstractThe purpose of this study was to assess the appropriateness of offensive tactical decision-making of Arab basketball players, and to determine if there are differences in the appropriateness of offensive tactical decision-making within the various disability classifications of Arab basketball players. A twenty-question survey was formulated to assess decision-making in offensive tactical situations in wheelchair basketball players. Participants in the present study were 108 athletes from 10 Arab national teams participating in wheelchair basketball. The mean offensive tactical thinking level of wheelchair basketball players in the 20 different situations in the Arab countries ranged between 1.38–2.84, and the standard deviations for these 20 means ranged from 0.41 to 0.90. The total mean of all tactical situations was 2.33, which is moderate thinking level. The influence of the disability classification on the offensive tactical thinking of wheelchair basketball players was addressed by examining the data via a one-way ANOVA. The ANOVA revealed no significant differences among disability classifications/categories in tactical thinking (F(3, 104)=1.12, p=0.34). This study represents the first attempt to identify why Arab nations have not consistently qualified for the Paralympics or World Championships. These findings indicate that the moderate offensive tactical thinking level of wheelchair basketball players on Arab national teams may be part of the reason that performances of these teams have not been as strong as they would like. 相似文献

实际比赛中田佳/王菲与阿德里安娜/谢尔达的体能分配比较 总被引：3，自引：1，他引：2
采用录像分析,对2005年世界沙滩排球巡回赛上海金山站女子比赛的中国队田佳/王菲与前奥运冠军巴西国家队阿德里安娜/谢尔达的体能分配进行比较。结果:在单场比赛中,4名队员的技术动作距离、时间分配比例相似,按从大到小的顺序均依次是走动、向前运动、向侧运动和向后运动;但是除跳发球的持续时间和移动距离较高以外,中国两名队员的快速动作、扣球和拦网的持续时间分配比例和移动距离均低于巴西运动员。表明中国优秀女子沙滩排球运动员在实际比赛中的体能分配、技战术的实效性等方面与国际顶级沙滩排球运动员存在差距。加强体能和技战术实效性训练,以及更加科学的训练监控将直接关系到2008年中国女子沙滩排球运动项目的竞技水平和运动成绩。 相似文献
