Tangled and Bumpy Roads to Gender Equity: Socio-Cultural Insights from Media Stories About Olympic Athletes and Motherhood

With the 2024 Olympic Games touted as reaching gender parity (i.e., same number of female and male athletes participating), media conversations are continuing about elite athlete mothers. Researchers interrogating media stories of Olympic athlete mothers have shown that their sporting journeys are not straightforward due to tensions linked to gender (in)equity. In this paper we use narrative inquiry as a theoretical lens to explore “comeback themes” synthesized from published media studies of Olympic athlete mothers, along with recent examples of media stories of Olympic athlete mothers. We discuss four comeback themes that include: (in)compatible identities, super mums, veteran status/age, and exposing discrimination, and some implications for gender equity. The first three comebacks perpetuate gender ideologies of heteronormative femininity, good motherhood, ageism, and exceptionalism, which downplay equitable support and change. These themes, along with the exposing discrimination theme, also highlight shifting media representations of motherhood and sport whereby stories expose struggles, realities, and/or structural deficits. We reflect on these themes as a “tangled and bumpy road” to gender equity led by athlete mothers’ voices resulting in changes in maternity rights. These comeback themes show gains in gender equity for sportswomen and highlight areas where more work is needed. Future research recommendations include studying mainstream and social media spaces with an intersectional lens to expand understanding of media stories as pedagogical resources to learn more about motherhood, sport, and gender (in)equity.

Association between FT3 Levels and Exercise-Induced Cardiac Remodeling in Elite Athletes.

Previous studies demonstrated that variations of fT3, even within the euthyroid range, can influence cardiac function. Our aim was to investigate whether thyroid hormones, even within the euthyroid range, are associated with the magnitude of exercise-induced cardiac remodeling in Olympic athletes. We evaluated 1342 Olympic athletes (mean age 25.6 ± 5.1) practicing different sporting disciplines (power, skills, endurance, and mixed). Athletes underwent blood testing (thyroid stimulating hormone, fT3, and fT4), echocardiography, and exercise-stress testing. Athletes taking thyroid hormones, affected by thyroiditis, or presenting TSH out of ranges were excluded. The level of thyroid hormones varied according to the type of sporting discipline practiced: endurance athletes presented the lowest TSH (p < 0.0001), fT3 (p = 0.007), and fT4 (p < 0.0001) in comparison to the remaining ones. Resting heart rate (HR) was positively correlated to fT3 in athletes of different disciplines (power: p = 0.0002, R2 = 0.04; skill: p = 0.0009, R2 = 0.05; endurance: p = 0.007, R2 = 0.03; and mixed: p = 0.04, R2 = 0.01). The same results were seen for peak HR in the exercise-stress test in athletes engaged in power, skill, and endurance (respectively, p < 0.0001, R2 = 0.04; p = 0.01, R2 = 0.04; and p = 0.005, R2 = 0.02). Moreover, a positive correlation was observed with cardiac dimensions, i.e., interventricular septum (power: p < 0.0001, R2 = 0.11; skill: p = 0.02, R2 = 0.03; endurance: p = 0.002, R2 = 0.03; mixed: p < 0.0001, R2 = 0.04). Furthermore, fT3 was directly correlated with the left ventricle (LV) end-diastolic volume in skills (p = 0.04, R2 = 0.03), endurance (p = 0.04, R2 = 0.01), and mixed (p = 0.04, R2 = 0.01). Thyroid hormones, even within the euthyroid range, are associated with cardiac adaptive response to exercise and may contribute to exercise-induced cardiac remodeling.

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

Ethnic and gender differences in plasma lipid composition have been widely reported among the general population, but there are scarce data on athletes. 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. 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.

Implementing an Organizational Trauma-Informed Approach to Olympic Sites: An Urgent Priority to Protect Elite Athlete Well-being During Olympic Games Participation

Abuse has been acknowledged as an adverse event which leads to trauma and long-term health effects in sport. Given the high rates of abuse occurring in elite sport contexts, many Olympic athletes will not only be subjected to abuse while residing and competing at the Olympic Games but may also experience trauma and its effects. In this article, we build on the calls for a trauma-informed approach in elite sport to outline a rationale for the International Olympic Committee (IOC) to implement an organizational trauma-informed approach to Olympic sites. Such an approach is essential because trauma researchers outside, and inside sport contexts, have outlined that when organizations are not trauma aware, and practices are not trauma-informed, unintended “unsafe” responses may result. To contextualize our rationale for an organizational trauma-informed approach, we provide examples of Olympic athletes’ stories to demonstrate the abuse and trauma they experienced while competing at the Olympic Games. To build on the human right that all athletes participating in the Olympic Games have the right to do so safely and free from harm, we further outline what an organizational trauma-informed approach involves and why it is important to limit re-traumatization risk. We further reflect on how being trauma-informed extends a duty of care to better protect athletes, which should be a responsibility of the IOC.

Mind or Medal: Elite Athletes’ Mental Health Management in Sports Events

There is a conversation in American athletics over the mental health experiences of athletes. Elite athletes encounter consequences ranging from mental well-being to mental illness. Some experts are concerned health of Tokyo 2020 Olympic and Paralympic Games athletes. The proliferation of research on elite athletes’ mental health culminated in the International Olympic Committee’s (IOC) Expert Consensus Statement. Given the importance of athletes’ mental health, this case study reviews the literature and the relevance of athletic identity to the diagnosis, treatment, and prognosis of poor mental health and fills the gap in theory/research and practice in elite sport.

Cardiac Adaptation in Power Athletes: Differential Impact of Judo and Weightlifting.

Background: According to the ESC guidelines, sport disciplines are classified in relation to the predominant component (skill, power, mixed and endurance), including a wide range of disciplines with different isometric/isotonic exercises and exercise-induced heart remodeling. The aim of our study was to evaluate differences in morpho-functional cardiac adaptations in power athletes, comparing judokas with weightlifters. Methods: We enrolled 55 Olympic athletes (38 judokas, 17 weightlifters), aged 24.5 ± 3.8 years, 25 (45.4%) of whom were males, and they underwent a pre-participation evaluation, including a physical examination, ECG, transthoracic echocardiogram, and exercise stress test. Results: The judokas presented significant differences in cardiac adaptations, with larger left ventricle (LV) end-diastolic and end-systolic volumes indexed (LVEDVi, p = 0.002 and LVESVi, p = 0.004) and higher LVMass values indexed (p = 0.033), but similar LV wall thicknesses (p = 0.093) and LV ejection fractions (p = 0.981). Also, the left atrium (LA) dimension (p = 0.0002) and volume indexed (p < 0.0001) were higher in the judokas, as were the larger right ventricle (RV) areas. Finally, the judokas showed higher VO2max (p = 0.012), O2 pulse (p = 0.007), VE/O2 LT1 (p = 0.041) and VE/O2 LT2 (p = 0.036) values, with a lower resting heart rate (p = 0.031) and higher exercise capacity (p = 0.011). Conclusions: The judokas showed substantial differences in cardiac morpho-functional adaptations from the weightlifters, and, accordingly, judo should be more properly considered not a pure strength sport but more similar to mixed disciplines of the ESC classification.

From Coubertin’s Olympism to neoliberal sports spectacle: narratives of Brazilian Olympic athletes

ABSTRACT This study aimed to examine how Brazilian athletes, who participated in the 2016 Olympic Games in Rio de Janeiro, perceive Olympism and its values within the context of their sports training, particularly considering the prevalent neoliberal elements in their high-performance sports environment. Semi-structured interviews were conducted with eight athletes from a region with a strong emphasis on competitive sports. The analysis revealed that athletes primarily associate Olympism with their personal experiences in sports. Their representations align with an Olympic and neoliberal framework, emphasizing performance and professionalism, while also recognizing them as moral exemplars. Athletes develop their understanding of sports values within the discourse of high-performance sports and daily routines. These findings highlight the integration of Olympism into athletes’ perceptions, shaped by the demands of neoliberal ideologies that prioritize competitiveness and commercialization within the sports domain. The study provides a critical perspective on the influence of neoliberalism on the formation of Olympic athletes’ subjectivity.

Doping Prevalence among U.S. Elite Athletes Subject to Drug Testing under the World Anti-Doping Code.

Determining the prevalence of doping within an elite athlete population is challenging due to the extreme sensitivity of the topic; however, understanding true doping prevalence is important when designing anti-doping programs and measuring their effectiveness. The objective of this study was to estimate the prevalence of doping among Olympic, Paralympic, World, and National-level competitive athletes in the United States subject to the World Anti-Doping Code. All athletes who were subject to the U.S. Anti-Doping Agency's Protocol for Olympic and Paralympic Movement Testing, a World Anti-Doping Code ("Code")-compliant anti-doping program, were invited to complete a web-delivered survey. Using a direct questioning approach, the survey items asked athletes whether they had used each specific category of banned substance / method on the World Anti-Doping Agency's Prohibited List. Multiple strategies to encourage honest reporting (e.g., protecting anonymity by collecting minimal demographic information; using an outside organization to administer the survey) and to detect inconsistent responses were used. Depending on the method of calculation, 6.5-9.2% of the 1,398 respondents reported using one or more prohibited substances or methods in the 12 months prior to survey administration. Specific doping prevalence rates for each individual substance / method categories ranged from 0.1% (for both diuretics / masking agents and stem cell / gene editing) to 4.2% for in-competition use of cannabinoids. Determining the prevalence of doping within different athlete populations is critical so that sport governing bodies can evaluate their anti-doping efforts and better tailor their programming. By measuring doping prevalence of specific categories of substances and methods, rather than just the overall prevalence of doping, this study also highlights where sport governing bodies should focus their future educational and detection efforts.

Wasted efforts of elite Marathon runners under a warming climate primarily due to atmospheric oxygen reduction

Meteorological conditions exert influences on sport performances via complex processes. Previous studies conventionally investigate the effects of weather conditions on marathon performance by following events held at the same places, which brings large uncertainties due to the changed participants. Via following each athlete to eliminate these uncertainties, we show that elite athletes’ marathon-running performance tends to monotonically worsen as ambient temperature rises except when it is extremely cold based on the best 16 athletes from each of the sex continents. It worsens by 0.56 (0.39 for men and 0.71 for women) min/°C when it rises beyond 15 °C. Theoretical analysis based on global marathon performance and weather observation datasets shows that more than half of this effect is mediated by reduced oxygen partial density as warmer temperature expands air and increases vapor pressure for both the men and women athletes, which is confirmed by the methods of Baron–Kenny. This atmospheric thermodynamic mechanism has not been emphasized previously. We also show that world-top athletes’ marathon performance approximately linearly worsens as ambient pressure decreases and slightly worsens as relative humidity rises if not extremely wet. These results substantially differ from the previous ones following the events instead of each athlete. Multi-variable changes in climate system are projected to slow Olympic marathon athletes by 2.51 and 1.06 min by the end of the 21st century in relative to 2020 under the high and intermediate emission scenario, respectively. Therefore, future progression of marathon performance is likely to be substantially slowed or even halted by climate changes without efficient greenhouse gas mitigation.

“Pochas sin identidad”: Raciolinguistic ideologies in the construction of mexicanidad in online spaces

ABSTRACT This study examines how ideas of Mexicanness are constructed on social media via raciolinguistic indexicals observed in the language practices of racialized individuals. I conducted discourse analysis on data collected from comments posted in four Olympic athletes’ tweets that emphasize different characteristics of Mexican identity. Findings suggest that the practices of alluding to language proficiency, whiteness, and cultural sentiment lead to a “double stigmatization” that racialized the players as “inherently linguistically deficient”. These criticisms, paired with misogynistic language, offended the players’ languages, bodies, sexualities, and intellect. The result of these harmful judgments exposes the raciolinguistic ideologies in the construction of a Mexican identity that perpetuates the myth of a desirable, better Mexican (i.e. Mexican national) and an undesirable, lesser Mexican (i.e. foreign born). This can result in the exclusion and erasure of transnational identities and perpetuate deficit perspectives of marginalized groups in both countries. Recognizing and challenging these raciolinguistic ideologies can help recognize the complexity of multicultural identities.

Para sport and anti-doping: a study of Swedish Para athletes' experiences and perceptions.

A well-functioning anti-doping system relies on being perceived by athletes as effective, fair, and practically feasible to implement. While research has highlighted the views of Olympic athletes on anti-doping over the past decade, the experiences and perceptions of Para athletes have not been extensively explored. The purpose of this study was to examine Swedish elite Para athletes' experiences and perceptions of the policy and practice of the anti-doping system. A quantitative cross-sectional approach was used, with a web survey elaborated from a survey with Olympic athletes adjusted for Para athletes with physical, visual, and intellectual impairments. The sample consisted of 66 active Para athletes competing at national or international level (response rate 71%). Data were analyzed using descriptive statistics and differences between subgroups were examined Fisher's exact test. Thematic analysis was employed to analyze open-ended questions. Most of the respondents expressed a positive outlook on the anti-doping system, advocating for comprehensive efforts. A significant portion (35%) had not received anti-doping education, with those who did reporting increased confidence in avoiding unintentional doping. Despite their elite status, half of the respondents had not undergone doping control. Mistrust regarding the system's effectiveness and fairness was identified, with over half of the participants emphasizing the need for new technical solutions to enhance procedures specifically tailored for Para athletes. The athletes in this study advocate for a Para sports-focused approach in the anti-doping system, emphasizing equal testing opportunities, procedural adjustments for independence and privacy, and increased access to education. The findings illuminate the unique conditions faced by athletes with impairments within the anti-doping system, offering valuable insights for policymaking in the development of anti-doping strategies tailored to Para athletes and their various impairments.

Using Generative AI to Facilitate Data Analysis and Visualization: A Case Study of Olympic Athletes

The ability to work with data is an important skill for students enrolled in technical and professional communication programs, but students with limited mathematical and computer programming literacies might find it difficult to do basic data analysis or customize data visualizations. This article examines the extent to which ChatGPT can make data analysis and visualization more accessible for students with limited technical proficiency. The results suggest that although the tool is poised to have a substantial impact in helping students create effective data visualizations, its efficacy as a data analysis tool is more limited.

Sleep Quality in Team USA Olympic and Paralympic Athletes.

To establish sleep-quality reference ranges for Olympic and Paralympic cohorts using the Pittsburgh Sleep Quality Index (PSQI) and explore differences based on sex and sport types. Team USA athletes (men = 805, women = 798) completed the PSQI as part of a health-history questionnaire. Descriptive statistics were used to create reference ranges and linear models, and χ2 test of independence determined differences in PSQI global and component scores between sex, games, season, and participation. Six hundred thirty-two (39.43%) athletes reported poor sleep (PSQIGlobal ≥ 5). Men displayed later bedtimes (P = .006), better global PSQI scores, shorter sleep latency, less sleep disturbance, and less use of sleep medication than women (all P < .001). Winter Games participants had later bedtime (P = .036) and sleep offset time (P = .028) compared with Summer Games athletes. Team-sport athletes woke earlier than individual-sport athletes (P < .001). Individual-sport athletes were more likely to have low (P = .005) and mild (P = .045) risk for reduced sleep duration than team-sport athletes. These data provide PSQI-specific reference ranges to identify groups at greatest risk for poor sleep, who may benefit most from targeted sleep interventions.

Next-generation sequencing reveals that miR-16-5p, miR-19a-3p, miR-451a, and miR-25-3p cargo in plasma extracellular vesicles differentiates sedentary young males from athletes.

A sedentary lifestyle and Olympic participation are contrary risk factors for global mortality and incidence of cancer and cardiovascular disease. Extracellular vesicle miRNAs have been described to respond to exercise. No molecular characterization of young male sedentary people versus athletes is available; so, our aim was to identify the extracellular vesicle miRNA profile of chronically trained young endurance and resistance male athletes compared to their sedentary counterparts. A descriptive case-control design was used with 16 sedentary young men, 16 Olympic male endurance athletes, and 16 Olympic male resistance athletes. Next-generation sequencing and RT-qPCR and external and internal validation were performed in order to analyze extracellular vesicle miRNA profiles. Endurance and resistance athletes had significant lower levels of miR-16-5p, miR-19a-3p, and miR-451a compared to sedentary people. Taking all together, exercise-trained miRNA profile in extracellular vesicles provides a differential signature of athletes irrespective of the type of exercise compared to sedentary people. Besides, miR-25-3p levels were specifically lower in endurance athletes which defines its role as a specific responder in this type of athletes. In silico analysis of this profile suggests a role in adaptive energy metabolism in this context that needs to be experimentally validated. Therefore, this study provides for the first time basal levels of circulating miRNA in extracellular vesicles emerge as relevant players in intertissue communication in response to chronic exercise exposure in young elite male athletes.
