Not least for this reason, the treadmill paradox, or Red Queen effect, easily discernable in market economies as a driver for change, whether progressive or destructive or both, can fruitfully be applied as an analytical lens through which to view sport. The question nevertheless remains to be answered as to whether the improved achievements of athletes lead to an improved spectator experience or the opposite. In this question lies an inherent paradox of contemporary world civilisation, with a literal as well as a metaphorical bearing on the critique of the unsustainable growth economy.Talent research has recommended that multidimensional assessments of performance are needed to improve the identification and development of talented young athletes. However, factors such as the relative age effect may cloud our ability to assess factors related to performance. The aim of this study was to determine the extent of any relationship between soccer players’ chronological and relative age, and objective and subjective performance assessments. Data for highly talented male soccer players selected into the German Soccer Associations’ talent promotion program (N = 16,138) for U12 to U15 age groups (M age = 12.62 ± 1.04 years) were examined. Besides anthropometric assessments, players completed a battery of five motor tests that objectively assessed speed abilities and technical skills (specifically sprint, agility, dribbling, ball control, and juggling). In addition, coaches subjectively rated players on their kicking, tactical, and psychosocial skills, as well as providing holistic evaluations of eagical age across age groups (0.03 ≤ |r| ≤ 0.07), and with relative age in each age group (0.01 ≤ |r| ≤ 0.11). The results show a skewed distribution toward early-born players and-in reference to their relative age-advanced performance in late-born athletes. However, trends toward a better holistic rating of early-born players for current and future performance levels were found. Coaches should be aware of these effects during talent selection, but also when interpreting results from subjective and objective assessments of performance.An increasing number of sport organizations express interest in international accreditation standards as a way of tackling environmental sustainability (ES) challenges. This article, however, argues that the commercial context of these standards and “the bazaar economy” in which its suppliers operate may hamper the diverse solutions needed to reduce the ecological footprint of sport. At the same time, it acknowledges that standards are useful to certain sporting organizations. To sort out the pros and cons of the relation between such standards and ES work in sport organizations, the Formula E (for Electric) championship is used as case example. The championship became the first category in motorsport to receive ISO certification in 2018, and 2 years later, it achieved net zero carbon footprint from inception. On that basis, the article provides a typology that provides coordinates for empirical research on how sport organizations may avoid “organizational hypocrisy” in their ES work by viewing the pros and cons of ISO certification. While the practical implication is insight into what it takes for a sport organization to achieve a specific certification, the academic implication is conceptual coordinates for empirical and comparative research of ES initiatives and certifications.While there has been research into what teams, leagues, and athletes post on social media and the impact of post content on social media engagement, there is limited understanding and empirical research on the impact of broadcasting media on social sport consumption. There are an increasing number of new media through which sport leagues can distribute their content to fans. This research examines the impact of different broadcast platforms on game day engagement with WNBA team Twitter accounts. Using data for the 2016-2018 seasons, results indicate athlete/team quality and performance were positively associated with post engagement, underscoring the importance of the core sport product and potentially indicating that the WNBA is developing a star-driven culture similar to the NBA. In addition, broadcasting on League Pass or local TV (for home teams) and Twitter were associated with lower post engagement suggesting we have more to learn about maximizing online engagement.Purpose To analyze sex and age group differences in strength, jump, speed, flexibility, and endurance performances of TeamGym athletes. Methods A total of 91 Swedish elite gymnasts (junior female, n = 26, age = 15.4 y; senior female, n = 23, age = 20.0 y; junior male, n = 19, age = 15.6 y; senior male, n = 23, age = 20.6 y) participated in three testing sessions on three separate days. These were (1) a series of flexibility tests for the lower- and upper-body; (2) strength tests for the lower- and upper-body; and (3) various types of jumps, a 20-m sprint-run, and a 3,000-m run test. selleck chemicals Results Males were 24% stronger in the back squat one-repetition maximum (relative to body mass) compared to females (P less then 0.001, H g = 1.35). In the pull-ups and dips, 2.4 and 2.3 times more repetitions were completed by the males compared to the females (both P less then 0.001, 0.70 ≤ R ≤ 0.77). However, females were similarly strong as males in the hanging sit-ups test (P = 0.724). The males jumped 29, 34, 33, and 17). Conclusions Large sex and age-group differences were observed for most physical performance metrics with specific within-sex age-group differences only observed for male athletes, with male seniors performing better than juniors in the SJ, CMJ, CMJa, and 20-m sprint-run tests.Sexual violence against athletes in elite and leisure sport has become of growing interest in recent years. In line with social media initiatives such as #SportToo and #CoachDontTouchMe and a rise in general media coverage, research in this field indicates an urgent need for action. These recent developments occasionally have led to no-touch policies, which may result in moral panic, uncertainty, and fear of unjustified suspicion among coaches. However, the role of closeness and distance in the development of sexual violence within the coach-athlete relationship has not yet been researched systematically. In this scoping review, the authors focus on the coach-athlete relationship, particularly its predispositions to sexual violence and how to prevent abusive relationships. Some characteristics typical of elite sport may predispose coaches to commit abuse, such as gender and power relations, the need for physical touch, hierarchical structures in sport, and trust and closeness between coaches and athletes. This scoping review follows an interdisciplinary approach combining sociological and psychological perspectives.
