The competition among cities to host a sports team or a large-scale international sports event is modeled as a winner-pay contest with an entry fee. In the first stage, each contestant (city) decides whether to pay the entry fee (infrastructure required by the team, for example), which allows it to participate in the second stage, that is, the actual contest. We show that the contest organizer’s choice of the optimal entry fee does not depend on the number of contestants. Furthermore, in some cases, the result is a form of zero-sum game, in which the sports team or event organizer is the main beneficiary. The findings shed light on this type of competition and under what conditions on the entry fee a city might benefit from hosting a sports team or large-scale international sports event.

There has been an increased interest in the effects the menstrual cycle (MC) may have on sports performance. As a part of the MC, many females experience a wide range of symptoms related to hormonal fluctuations and menstrual bleeding, including physical pain and mood disturbances. Currently, there is a lack of data on the MCs of females who participate in resistance training. The dearth of information on the regular MC in female athletes may lead to poorly informed training recommendations which may be detrimental for female athletic advancement. The purpose of this survey was to determine the average MC characteristics, hormonal contraceptive (HC) use and perceived effects of the MC on training in resistance-trained athletes, and to determine if there are differences in these variables when comparing recreationally trained women to competitive-level athletes. A survey addressing questions about the MC, HC use and perceived effects of the MC was accessed by 906 participants who self-identified as resistance-trained athletes. Resistance-trained athletes, competitive or not, experience MCs similar to data on other exercising females and the general population. MC symptoms are widespread and, for some, can be quite severe and limiting. Competitive athletes were not more likely to experience MC irregularities than non-competitive females. Nearly half of the participants reported using HCs. Most participants perceived that their MC had a negative effect on their performance and that their MC caused reductions in training load or workout program adherence, although most competitive-level athletes did not withdraw from competitions due to MC symptoms.
人们越来越关注月经周期（MC）对运动表现的影响。作为月经周期的一部分，许多女性会出现与荷尔蒙波动和月经出血有关的各种症状，包括身体疼痛和情绪紊乱。目前，有关参加阻力训练的女性 MCs 的数据还很缺乏。女性运动员常规 MC 信息的缺乏可能会导致训练建议缺乏依据，从而不利于女性运动员的进步。这项调查的目的是确定阻力训练运动员的平均 MC 特征、荷尔蒙避孕药（HC）的使用情况以及 MC 对训练的影响，并确定在比较休闲训练的女性和竞技水平的运动员时，这些变量是否存在差异。有 906 名自我认定为阻力训练运动员的参与者参与了一项调查，其中涉及有关 MC、HC 使用情况和对 MC 影响的认知等问题。无论是否为竞技运动员，阻力训练运动员的 MC 症状与其他运动女性和普通人群的数据相似。MC症状很普遍，对某些人来说，可能会相当严重并造成限制。与非竞技女性相比，竞技运动员并不更容易出现 MC 不正常现象。近一半的参与者表示使用过碳氢化合物。大多数参与者认为 MC 对她们的表现有负面影响，MC 会导致训练负荷减少或锻炼计划的坚持度降低，尽管大多数竞技级运动员并未因 MC 症状而退出比赛。

Supporting high-level performance is increasingly seen as a team game, reflected in the growth in support services. Coaches and management must work effectively with various practitioners to deliver the required support to athletes. To date, how coaches experience these support teams has yet to be explored. Accordingly, we utilized a qualitative research design with semistructured interviews to examine coach-consumers’ perceptions of more or less effective practice. Eight high-level coaches were recruited, and data was analyzed using reflexive thematic analysis. Key themes generated included the make-up and conduct of high-performing teams, prioritizing coach–practitioner relationships, and professional development considerations for both coaches and practitioners. Data suggest that practitioners are seen as playing a crucial role in elite sports performance, and coaches generally have a positive view of the contributions of sports science teams. Notably, however, several challenges were identified, including communication issues, conflicts over the allocation of resources, recruitment of, and the need for sports scientists to understand the demands of sports and the coaching process. Findings have practical implications for support teams and coaches working in high-performance sports; specifically, in the recruitment and development of sports science and medicine practitioners and coaches.

Judo is a dynamic and complex sport, and therefore talent programs may benefit from a multidimensional approach to identify clear and reliable performance characteristics in order to monitor and train athletes. However, from both a practical and theoretical point of view, understanding on this topic is limited. This systematic review therefore aimed to (1) identify which multidimensional performance characteristics can discriminate between different performance levels of judoka and (2) find the gaps in literature. To categorize the findings the Groningen Sport Talent Model (GSTM) was applied. A systematic search of MEDLINE, PsycINFO, PubMed, and Web of Science was performed following the PRISMA guidelines. In total 23 studies with good to excellent methodological quality were included. All performance characteristics of the GSTM (anthropometrical, physiological, technical, tactical, and psychological) were represented in the included studies. There is strong evidence to suggest that a broad set of physiological characteristics is needed to manage the demands of judo combats. Additionally, there is strong evidence that performance characteristics related to grip fighting discriminate between judoka of different performance levels and higher performance level judoka are characterized by the ability to throw their opponent and to variate in technique. The findings of this review can be used as a basis for talent development and identification in judo, and to optimize training programs. Future research should focus on increasing the understanding of psychological characteristics of judoka and the multidimensional talent trajectory by conducting longitudinal studies.
柔道是一项动态而复杂的运动，因此，人才计划可能会受益于多维方法，以确定明确可靠的成绩特征，从而对运动员进行监测和培训。然而，从实践和理论的角度来看，对这一主题的理解都很有限。因此，本系统综述旨在：(1) 确定哪些多维性能特征可以区分柔道运动员的不同性能水平；(2) 找出文献中的不足之处。为了对研究结果进行分类，采用了格罗宁根运动天赋模型（GSTM）。按照 PRISMA 准则，对 MEDLINE、PsycINFO、PubMed 和 Web of Science 进行了系统检索。共纳入了 23 项方法学质量良好至优秀的研究。GSTM 的所有性能特征（人体测量、生理、技术、战术和心理）在纳入的研究中均有体现。有确凿证据表明，柔道比赛需要一系列广泛的生理特征。此外，有确凿证据表明，与握力格斗相关的表现特征可区分不同水平的柔道运动员，而较高水平的柔道运动员的特点是有能力将对手摔倒并在技术上有所变化。本综述的研究结果可作为柔道人才培养和识别的依据，并可用于优化训练计划。今后的研究应侧重于通过开展纵向研究，加深对柔道运动员心理特征和多维人才轨迹的了解。

Sixty-two percent of Finnish children and adolescents aged 9–15 participate in sports club activities, yet only one-third of sports participants reach the recommended 60 min of daily moderate-to-vigorous physical activity. The inadequate physical activity of participants underlines the need for physical education among those participating in sports club activities. Sports coaches have significant potential in promoting participants’ weekly overall physical activity beyond sports training, given their role of authority. However, coaches in Finland mainly work on a voluntary basis, with varying knowledge and capabilities. The aim of the study was to investigate the physical education orientation and activity of sports coaches, and the associations of these with the moderate-to-vigorous physical activity of young sports participants. Questionnaire data from coaches ( n = 26) and young sports participants aged 6–18 ( n = 201), and accelerometer data from young sports participants ( n = 293) were included in the analysis. The results indicated that even though sports coaches recognized the importance of physical education, they have not fully embraced their role as physical educators and promoters of weekly overall physical activity among young sports participants. The role of families was considered most significant in physical education. Coaches perceived their possibilities to influence the physical activity behavior of the participants as limited. Coaching education and experience had a positive relationship with the coaches’ activity in implementing physical education, highlighting the importance of coaching education. The findings suggest that there is a need to increase collaboration with coaches and families to ensure an adequate amount of weekly overall physical activity of children and adolescents.

The purpose of this study was to determine if there was an association between concussion understanding and stakeholder knowledge translation in collegiate sports following the mandate of Rowan's Law in Ontario, Canada. To our knowledge, this is the first study to examine concussion knowledge translation within a sport network using social network analysis. A cross-sectional design was used to evaluate 76 collegiate athletes (54 females, 21 males, 1 not identified), aged 20.55 years (SD = 3.4) who completed a survey on sport demographics, concussion knowledge and stakeholders who provided concussion information during the sport season. Athlete concussion knowledge scores and reported stakeholders were examined. An average of three key stakeholders provided concussion information to 82% of the varsity athletes in our study. Athletes reported that a coach or athletic trainer most often provided concussion knowledge. Overall, athlete concussion knowledge scores were the same for athletes who sought concussion knowledge from stakeholders and those who did not. Over 95% of athletes in the study did not access the Rowan's Law website for mandated concussion education. These findings suggest that Rowan's Law is hugely neglected resulting in stakeholder knowledge translation having minimal influence on an athletes’ understanding of concussions. Future recommendations include verified review of mandated concussion education resources and testing of concussion knowledge for all persons associated with sport in Ontario. Due to the number of athletes seeking concussion knowledge in their varsity athlete network, accurate sport specific resources should be provided to support stakeholders who are in direct contact with athletes.
