Human rights and the olympics: from an ideological paradox to a new anti-corruption legacy.

This article aims to explore the evolution of the debates surrounding human rights in the discourse(s) of major sporting events (MSEs), particularly the Olympics. The paper will first analyse the western-centric origins of the "universality" of the Olympic philosophy and how it affected the protection and promotion of human rights, as well as addressing practical challenges or limitations faced. It will then focus on unpacking the elements of sportswashing and soft power in the multi-discursive context of sport where power, privilege, politics, and position are (re)produced. In doing so it draws upon the emergent field of Sports Diplomacy as the most appropriate explanatory framework to share in this discourse. Finally, it will explore the potential impact of anti-corruption reforms on the establishment of a meaningful human rights legacy.

The effect of post-activation enhancement on the performance of Chinese national skeleton athletes in the "ice push sled"-a first cross-sectional study.

Objective: To investigate the impact of post-activation potentiation (PAP) induced by resisted sled sprint at different loads on the subsequent 30 m ice push sled performance of Chinese skeleton athletes, and to identify the resisted sled sprint load that most effectively enhances PAP for Chinese skeleton athletes. Methods: Seven elite athletes from the Chinese skeleton team participated in four tests with more than 48 h intervals. During the tests, on the first test, athletes completed a 40 min standard warm-up, rested for 6 min, and then performed a 30 m test. On the second, third, and fourth test, athletes completed the standard warm-up, then performed 20 m sprints with resisted sled (RS) at 75%, 50%, and 25% of body mass (BM), respectively, rested for 6 min, and then performed the 30 m test. Results: No significant differences were found in morning pulse, blood urea, and creatine kinase levels among four tests. The percentage of maximum heart rate (%HRmax) within different intensity ranges showed no significant differences among four tests. However, significant differences were observed in ice push sled performance among four tests (No BMRS: 5.08 ± 0.27; 25% BMRS: 5.05 ± 0.29; 50% BMRS: 5.02 ± 0.27; 75% BMRS: 5.04 ± 0.28). Post hoc analyses revealed that the 50% BMRS test had faster speed compared to the no resistance (p < 0.05), the 25% BMRS (p < 0.05), and the 75% BMRS (p < 0.05) tests. Additionally, the 75% BMRS test had faster speed than the no resistance test (p < 0.05). Conclusion: A 20 m sprint with 50% BMRS effectively enhances the PAP effect in skeleton athletes, improving their ice push sled performance. Coaches can incorporate this resisted sled sprint in athletes' training routines for performance enhancement in both daily training and pre-competition preparations.

Exploring the dynamics of Women's field hockey performance: A comparative analysis of the impact of opponent quality between Olympic Games and Chinese National Games.

This is an observational retrospective study analyzed the performance of the Chinese women's national field hockey team during the 2020 Tokyo Olympics and 2021 National Games to assess the impact of opposition quality on performance. Game statistics were collected using notational analysis software for 76 Olympic and 40 National Games matches. Non-parametric Mann-Whitney U tests were used to compare tournaments. No significant differences existed for 35 out of 38 metrics, except Offense in 25-Yd Area (P = 0.013), Handball Style (P = 0.000) and Entry into Arc - Right Lane (P = 0.017). When exclusively considering Chinese national team's observations, superior National Games performance did emerge for Shot (P = 0.046), Goal from Short Corner (P = 0.044), Into the Arc (P = 0.046), Entry into Arc - Q3 (P = 0.009), Dribble into the Arc (P = 0.046), Handball Style into Arc (P = 0.041), Forehand Shot (P = 0.033), and Small Skill Shot (P = 0.014). The study underscores the influence of opposition quality on team performance, with a need for targeted improvements in arc penetration efficacy, conversion rates of shots to goals, and adaptation of tactical approaches against stronger defenses. The research points towards the need for strategic high-performance programs, improved domestic league quality, and a structured youth development system to elevate the overall standard of Chinese field hockey to achieve global competitiveness.

A study on the grey relation analysis between the overall performance and individual event scores of international elite trampolinists.

This study applied grey relational analysis to assess the relationship between individual trampoline event scores and overall performance of top male and female athletes in the 2020 Tokyo Olympics. Analyzing execution, horizontal, difficulty, timing of flight, and total scores, results showed males excelled significantly in difficulty, timing, and overall performance, while execution and horizontal scores were comparable. For males, timing of flight (excluding outliers) had the greatest influence on total score, followed by difficulty and execution. In females, difficulty dominated, followed by timing and horizontal, with execution least impactful. The study highlighted the primary roles of timing and difficulty scores in overall trampoline performance, with gender variations in score contributions. The findings illuminated the interplay of score components, offering a theoretical framework for targeted trampoline training. For international athletes, key considerations included boosting height index for a robust trampoline foundation; tailoring difficulty levels to athletes' abilities while adhering to scoring rules, without sacrificing technical prowess; and sustaining training to refine quality and stability of routines.

Survival of out-of-hospital cardiac arrest patients admitted to the hospital during the Tokyo Summer Olympic and Paralympic Games in Japan.

Background: The influence of the Tokyo Summer Olympic/Paralympic Games on normal emergency medical system operations in Japan had not yet been fully elucidated. In this study, we examined whether out-of-hospital cardiac arrest (OHCA) patients treated during the Tokyo Olympic/Paralympic Games had differences in outcomes. Methods: Using the nationwide JAAM-OHCA Registry, we evaluated the outcomes of OHCA patients admitted to the hospital during the Tokyo Olympic/Paralympic Games (July 23 to Aug. 8 and Aug. 24 to Sept. 5) in 2021, compared to those during same the dates in 2020 (Term 1: July 23 to Aug. 8 and Aug. 24 to Sept. 5), those during the pre-Olympic/Paralympic term during the same weekdays in the weeks before the event (Term 2: June. 18 to July. 4 and July. 6 to July. 18), and those during the post-Olympic/Paralympic term during the same weekdays in the weeks after the event (Term 3: Sept. 10 to Sept. 26 and Sept. 28 to Oct. 10). The primary outcome was 30-day survival, and multivariable logistic analysis was performed, adjusted for age and sex. Results: A total of 3,111 OHCA patients were included in the study period (786 in the Olympic/Paralympic group, 774 in Term 1, 747 in Term 2, and 804 in Term 3). Crude 30-day survivals were 7.4% (58/786), 9.3% (72/774), 6.8% (51/747), and 8.2% (66/804), respectively. Using the Olympic/Paralympic group as a reference, multivariable logistic analysis revealed that 30-day survivals in Term 1 (OR 1.27 95% CI 0.88-1.83p = 0.20), Term 2 (OR 0.92 95% CI 0.62-1.36p = 0.67), and Term 3 (OR 1.10 95% CI 0.76-1.59p = 0.63) did not differ significantly. Conclusions: No significant differences in 30-day survival for OHCA patients admitted during the Tokyo Summer Olympic/Paralympic Games were identified.

Dengue virus and the 2024 Paris Olympics.

The 2024 Paris Olympics and Paralympics face concerns over dengue virus transmission, despite Paris's lower mosquito activity. Preventive measures include eliminating breeding sites, insecticide spraying, and public awareness. Health systems will monitor and respond to cases. Large gatherings like the Olympics can amplify disease spread, as seen with Zika in Rio 2016. Recent reports confirm dengue presence in Europe, highlighting global risks. While Paris's overall dengue risk is low, even a few cases could impact global health. Collaboration among health authorities, researchers, and event organizers is crucial to ensure participant and public safety during the games.

Building a healthy nation: A white paper on Olympic sports and the Indian education system.

The Indian education system has produced top-class global corporate leaders in recent decades. The combination of a solid educational foundation, work ethic, adaptability, technical and analytical skills, leadership abilities, networking, entrepreneurial spirit, and cultural values collectively contribute to the success of Indian students and professionals in the corporate world. On the contrary, India's overall performance in Olympic sports has been modest compared to its population and potential. The education system of any country has a significant role in sporting success. To fully harness the potential of sports in schools, addressing these challenges and creating a supportive environment that values and promotes sporting abilities alongside academic excellence is essential. This will require concerted efforts from various stakeholders, including the schooling system, educational institutions, government, sports organizations, corporate sponsors, and the community. This white paper aims to systematically organize the available knowledge and debates around India's sporting performance in the background of mainstream education culture. This paper also addresses the systemic devaluation, exclusion, disfranchisement, and stereotyping of sports and sportspersons in India. One key argument put forward in this paper is to extend absolute equivalence to Olympic sports disciplines (e.g., football) at par with general academic disciplines (e.g., mathematics) in terms of examinations and award of qualifications within the mainstream education system of India. And India must host the Olympics before 2047.

Powering Toward Los Angeles: Comparing Power Output and Pacing Approach Between Maximal 2000- and 1500-m On-Water Racing in Elite Rowers.

PURPOSE: To compare power output and pacing between maximal 1500- and 2000-m on-water rowing performances. METHODS: Twenty-six (female n = 4, male n = 22) international rowers, across 6 boat classes, completed maximal 1500- and 2000-m on-water races, separated by 24 to 48 hours. Crew combinations and seat orders remained consistent between races. Peach PowerLine instrumentation measured power output and stroke rate. Differences in completion time, mean power output (MPO), percentage prognostic velocity (PPV; percentage of world record velocity in each boat class), stroke rate, and pacing variance were assessed using linear mixed modeling. RESULTS: Compared with 2000-m, completion times were 90.4 (6.1) seconds shorter over 1500 m (-24.7% [0.7%]). Both MPO (P = .255, ηp2=.06) and PPV (P = .340, ηp2=.18) were not different between distances. Broadly, crews adopted a reverse-J-shaped pacing across both distances, demonstrating a reduced variance over 1500 m (P = .035, ηp2=.62). Percentage change in MPO from 2000 to 1500 m demonstrated a strong negative association with pacing variance over 1500 m (R2 = .74, P = .027). CONCLUSIONS: International rowing crews did not increase MPO or PPV when racing maximally over 1500 m compared to 2000 m. Comparable strategies were adopted over both distances, with less variance in pacing observed over 1500 m. The crews that demonstrated greater increases in MPO over the shorter race employed a flatter pacing strategy. To improve 1500-m on-water performance, rowers may need to adopt a more even pacing approach.

The arena or E-games triathlon as a unique real world and virtual mixed-model endurance sports event.

The sport of triathlon has evolved to become a discipline comprising races of different lengths and formats. It has also undergone significant growth in popularity and exposure with several variations in format from the classic swim - bike - run combination attracting significant television and media coverage. Since 2021 an original and unique format called the Arena Games Triathlon (or in 2024 the E-Games) has evolved that involves athletes competing against each other in swimming, cycling and running combining both the real and virtual worlds in one race. This model of endurance sport is currently unique, provides instantaneous data on performance and has the potential to be a tool for performance prediction, talent selection and sport development. The goal of this perspective paper is to provide context around the emergence of the Arena Games Triathlon series, describe the format of this type of racing, outline how it has the potential to drive training and evaluation of triathletes and discuss the attractiveness of its future inclusion as an Olympic discipline.

Setting sail for Paris 2024: Retrospective analysis of world-class ILCA 7 Olympic sailors' cardiorespiratory fitness (2015-2020).

The aim of this retrospective analysis was to provide a more comprehensive understanding of the cardiorespiratory profile of world-class ILCA-7 sailors (n = 3, all males), through a longitudinal evaluation offering real-world data on physiological profile and exercise intensity domains. The cardiopulmonary exercise testing (CPET) was performed by the same researchers using the same equipment during the study. Assessments took place twice a year, aligning with major international competition preparations. Participants trained and competed at the same sailing club in Split, Croatia, under consistent supervision from the same team throughout the study, winning a total of 21 medals at major international competitions. The recorded V ̇ O 2 peak ${{\dot{V}}_{{{{\mathrm{O}}}_{\mathrm{2}}}{\mathrm{peak}}}}$ ranged from 51.7 ± 1.6 to 61.9 ± 3.0 mL min-1 kg-1, respectively. Similarly, peak power output varied from 352 ± 10 to 426 ± 34 W. The changes in physiological responses at the ventilatory thresholds were proportional to the changes in peak cardiorespiratory fitness capacity. Interestingly, the oxygen pulse measured in 2015 was 25 ± 1 mL O2 beat-1. Over the subsequent 6 years, the O2 pulse marginally increased and appeared to stabilize at 27 ± 1 mL O2 beat-1 in 2020, when these athletes were 32 ± 3 years old. This work offers a broader understanding of world-class Olympic sailors' cardiorespiratory fitness, going beyond the standard assessment of peak V ̇ O 2 ${{\dot{V}}_{{{{\mathrm{O}}}_{\mathrm{2}}}}}$ to incorporate an analysis of ventilatory thresholds. While a direct link between cardiorespiratory fitness and competitive success remains ambiguous, the importance of a well-rounded aerobic capacity for excellence in ILCA-7 sailing class is evident. HIGHLIGHTS: What is the central question of this study? What are the temporal changes in the physiological profiles of three world-class ILCA-7 sailors? What is the main finding and its importance? Data on oxygen pulse adjustments suggest the involvement of compensatory cardiovascular mechanisms, likely associated with the isometric and quasi-isometric contractions inherent in ILCA-7 sailing. This is evidenced by the absence of an age-related increase in oxygen pulse, a phenomenon often observed in endurance athletes throughout their competitive careers.

Identifying Driving Factors of Atmospheric N2O5 with Machine Learning.

Dinitrogen pentoxide (N2O5) plays an essential role in tropospheric chemistry, serving as a nocturnal reservoir of reactive nitrogen and significantly promoting nitrate formations. However, identifying key environmental drivers of N2O5 formation remains challenging using traditional statistical methods, impeding effective emission control measures to mitigate NOx-induced air pollution. Here, we adopted machine learning assisted by steady-state analysis to elucidate the driving factors of N2O5 before and during the 2022 Winter Olympics (WO) in Beijing. Higher N2O5 concentrations were observed during the WO period compared to the Pre-Winter-Olympics (Pre-WO) period. The machine learning model accurately reproduced ambient N2O5 concentrations and showed that ozone (O3), nitrogen dioxide (NO2), and relative humidity (RH) were the most important driving factors of N2O5. Compared to the Pre-WO period, the variation in trace gases (i.e., NO2 and O3) along with the reduced N2O5 uptake coefficient was the main reason for higher N2O5 levels during the WO period. By predicting N2O5 under various control scenarios of NOx and calculating the nitrate formation potential from N2O5 uptake, we found that the progressive reduction of nitrogen oxides initially increases the nitrate formation potential before further decreasing it. The threshold of NOx was approximately 13 ppbv, below which NOx reduction effectively reduced the level of night-time nitrate formations. These results demonstrate the capacity of machine learning to provide insights into understanding atmospheric nitrogen chemistry and highlight the necessity of more stringent emission control of NOx to mitigate haze pollution.

In the world of top-level sport, optimising athletic performance does not rely solely on physical training. Taking into account the intestine-brain axis offers new ways of optimising sports preparation, partly thanks to the role of the intestinal microbiota on performance and well-being.

"Falling Behind," "Letting Go," and Being "Outsprinted" as Distinct Features of Pacing in Distance Running.

INTRODUCTION: In distance running, pacing is characterized by changes in speed, leading to runners dropping off the leader's pace until a few remain to contest victory with a final sprint. Pacing behavior has been well studied over the last 30 years, but much remains unknown. It might be related to finishing position, finishing time, and dependent on critical speed (CS), a surrogate of physiologic capacity. We hypothesized a relationship between CS and the distance at which runners "fell behind" and "let go" from the leader or were "outsprinted" as contributors to performance. METHODS: 100-m split times were obtained for athletes in the men's 10,000-m at the 2008 Olympics (N = 35). Split times were individually compared with the winner at the point of "falling behind" (successive split times progressively slower than the winner), "letting go" (large increase in time for distance compared with winner), or "outsprinted" (falling behind despite active acceleration) despite being with the leader with 400 m remaining. RESULTS: Race times ranged between 26:55 and 29:23 (world record = 26:17). There were 3 groups who fell behind at ∼1000 (n = 11), ∼6000 (n = 16), and ∼9000 m (n = 2); let go at ∼4000 (n = 10), ∼7000 (n = 14), and ∼9500 m (n = 5); or were outkicked (n = 6). There was a moderate correlation between CS and finishing position (r = .82), individual mean pace (r = .79), "fell behind" distance (r = .77), and "let go" distance (r = .79). D' balance was correlated with performance in the last 400 m (r = .87). CONCLUSIONS: Athletes displayed distinct patterns of falling behind and letting go. CS serves as a moderate predictor of performance and final placing. Final placing during the sprint is related to preservation of D' balance.

Participation in Special Olympics reduces the rate for developing diabetes in adults with intellectual and developmental disabilities.

AIM: Adults with intellectual and developmental disabilities (IDD) have a significantly higher prevalence of Type 2 diabetes than the general population. Evidence that lifestyle and/or behavioural interventions, such as participation in Special Olympics, decreases the risk of developing diabetes in adults with IDD could help minimize health disparities and promote overall health in this population. METHODS: This was a 20-year retrospective cohort study of adults with IDD (30-39 years) in the province of Ontario, Canada, that compared hazard rates of diabetes among Special Olympics participants (n = 4145) to non-participants (n = 31,009) using administrative health databases housed at ICES. Using cox proportional hazard models, crude and adjusted hazard ratios were calculated for the association between the primary independent variable (Special Olympics participation status) and the dependent variable (incident diabetes cases). RESULTS: After controlling for other variables, the hazard ratio comparing rates for developing diabetes between Special Olympics participants and non-participants was 0.85. This represents a 15% reduction in the hazard among Special Olympics participants when followed for up to 20 years. This result was statistically significant and represents a small effect size. CONCLUSIONS: Special Olympics could be considered a complex intervention that promotes physical activity engagement through sport participation, health screenings, and the promotion of healthy eating habits through educational initiatives. This study provides evidence that Special Olympics participation decreases the rate for developing diabetes.

Podiatric conditions observed in Special Olympics athletes: Contrasting data from a USA versus an international population.

OBJECTIVES: Persons with intellectual disabilities frequently have podiatric conditions. Findings from the 2018 United States Summer games (USA) venues are compared to those from athletes screened at the 2019 Special Olympics World Summer Games in Abu Dhabi, United Arab Emirates (UAE). METHODS: Data from Fit Feet screenings from 2445 United Arab Emirates (UAE) participants were compared to 1244 US participants. RESULTS: A sampling of results that reflect significant differences in findings between the USA cohort and Abu Dhabi cohort include ankle joint range of motion, excessive abduction, hallux abducto valgus and pes planus. The overall shoe to foot mismatch was found to be 52.2%. A professional referral was recommended 27.7% of the time in the USA data and 28.5% in the Abu Dhabi data. An urgent referral was requested 5.1% of the time for the USA data and 3.7% of the time in the Abu Dhabi data. CONCLUSION: Special Olympics athletes experience a greater prevalence of identifiable podiatric conditions as compared to the general population. Several of the conditions investigated in this study differed significantly between the international Special Olympics cohort and the USA cohort. Assessment of the feet of Special Olympics athletes can help to better appreciate the podiatric conditions in a population of individuals with intellectual disabilities. The variance identified between populations of Special Olympics athletes may be a reflection on the lack of standardization of conditions that are assessed for as well as the disparate characteristics of the clinical volunteers. Future Fit Feet events may wish to consider significant improvements in objectivity and standardization as it pertains to the conditions that are evaluated for in the Fit Feet exam.

Differences Between Afro-Caribbean and White Caucasian Olympic Athletes in Plasma Lipids Profile: A Cross-Sectional Single Center Study.

INTRODUCTION: Ethnic and gender differences in plasma lipid composition have been widely reported among the general population, but there are scarce data on athletes. AIM: To assess ethnic and gender differences in lipid profile across a large cohort of Olympic athletes practicing different sport disciplines METHODS: We enrolled 1165 Olympic athletes divided into power, endurance, and mixed disciplines according to European Society of Cardiology classification. Sixty-two (5.3%) were Afro-Caribbean. Body composition and fat mass percentage were measured. Blood samples were collected and lipid profile was investigated. RESULTS: Compared to Caucasians, Afro-Caribbeans had better lipid profile characterized by lower LDL (90 ± 25 mg/dL vs. 97.1 ± 26.2 mg/dL, p = 0.032) lower LDL/HDL ratio (1.39 ± 0.5 vs. 1.58 ± 0.6, p = 0.012), lower non-HDL-cholesterol (102.5 ± 27.4 mg/dL vs. 111.5 ± 28.5 mg/dL, p = 0.015) and lower TC/HDL (2.59 ± 0.6 vs. 2.82 ± 0.7, p = 0.010). Female Afro-Caribbeans showed lower TG/HDL ratio (p = 0.045) and TC/HDL ratio (p = 0.028), due to higher HDL (p = 0.005) compared to male Afro-Caribbeans. In Caucasian athletes, females showed even more evident differences with lower TC, LDL, and higher HDL with subsequent lower ratios compared to men. Moreover, endurance Caucasian athletes had lower LDL (p = 0.003) and TG (p = 0.017) plasmatic levels and higher HDL levels compared to non-endurance Caucasian athletes (p< 0.0001) CONCLUSIONS: Ethnicity and gender have a significant influence on plasmatic lipid balance in elite athletes and Afro-Caribbeans have favorable lipid profiles compared to Caucasians. Moreover, endurance sports, particularly in Caucasian athletes, are associated with better lipid profile compared to other type of sports.

Be strong, be confident: the rise of China and the 2022 Beijing Winter Games.

Drawing on promotional materials in 2007-2008 and in 2021-2022, this article examines both Olympics to explore how the state has evolved in its governmental rationalities, and the related cultural and political implications. The 2022 Winter Games, despite its comparatively low profile and challenges posed by Covid-19, provided the Chinese state with a key moment to advance its confidence doctrine. Three discourses were mobilised pertaining to, first, the CCP's superb leadership and problem-solving skills; second, China's mega-infrastructure; and, third, created + made in China. The 2022 Olympics thus mobilised three confidence-driven discourses: leadership confidence, techno-scientific confidence, and creative confidence. In doing so, the 2022 Olympics envisioned, narrated, and materialised the popular discursive signifiers - technology, green and sustainability, and the future - the authorities already actively promoted in its political initiatives and policies. This contributed to the inward-oriented beliefs of self-reliance and self-improvement. Where we witnessed in 2008 a sense of curiosity and openness, within China and the world at large, we now face the complexities, dangers, and cultural essentialism, if not narcissism, of a confident China.

Incidence of staff injury and illness at the Tokyo 2020 and Beijing 2022 Olympic and Paralympic Games.

Objective: To report epidemiological data regarding injury and illness among the Team USA staff during the Tokyo 2020 Summer Olympic and Paralympic Games and Beijing 2022 Winter Olympic and Paralympic Games. Methods: A retrospective review of all Team USA staff (total staff, N=1703 (62.5% female); total staff days (SD)=34 489) medical encounters during the Tokyo 2020 Games and Beijing 2022 Games was conducted. Details related to injury and illness were evaluated. Incidence with 95% CI per 1000 staff days were calculated. Results: A total of 32 illnesses (incidence [95% CI] 0.9 [0.6, 1.2]) and 23 injuries (incidence 0.7 [0.4, 0.9]) were sustained by the Team USA delegation staff members during the Tokyo 2020 Games and Beijing 2022 Games. Female staff reported more illnesses (illnesses proportion (IP) 2.9%; incidence 1.4 [0.8, 2.0]), while male staff incurred more injuries (IP 1.8%; incidence 0.9 [0.5, 1.3]). When stratified by physiological system, dermatological and infectious were the most common systems involved with illness (IP 0.5%; incidence 0.2 [0.1, 0.4]). Injuries to the upper limb were most common (IP 0.3%; incidence 0.3 [0.1, 0.5]). Conclusion: Injury and illness rates among the Team USA staff during the Tokyo 2020 Games and Beijing 2022 Games were low, but notable. Knowledge of injury and illness risks contributes to staffing decisions and prevention strategies for staff supporting athletes during competition.
