Objective: Research in sports medicine and exercise science has experienced significant growth over recent years. With this expansion, there has been a concomitant rise in ethical challenges specific to these disciplines. While various ethical guidelines exist for numerous scientific fields, a comprehensive set tailored specifically for sports medicine and exercise science is lacking. Aiming to bridge this gap, this paper proposes a comprehensive, updated set of ethical guidelines specifically targeted at researchers in sports medicine and exercise science, providing them with a thorough framework to ensure research integrity. Methods: A collaborative approach was adopted, involving contributions from a diverse group of international experts in the field. A thorough review of existing ethical guidelines was conducted, followed by the identification and detailed examination of 15 specific ethical topics relevant to the discipline. Each topic was discussed in terms of its definition, consequences, and preventive measures. Results: The research in sports medicine and exercise science has grown significantly, bringing to the fore ethical challenges unique to these disciplines. Our comprehensive review identifies 15 key ethical challenges: plagiarism, data falsification, role of artificial intelligence chatbots in academic writing, overstating results, excessive/strategic self-citation, duplicate publications, non-disclosure of conflicts of interest, image manipulation, misuse of peer review, ghost and gift authorship, inadequate data retention, data fabrication, falsification of IRB approvals, lack of informed consent, and unethical human or animal experimentation. For each identified challenge, we propose practical solutions and best practices, enriched by the diverse perspectives of our collaborative international expert panel. This endeavor aims to offer a foundational set of ethical guidelines tailored to the nuanced needs of sports medicine and exercise science, ensuring research integrity and promoting ethical responsibility across these vital fields. Conclusion: This article represents a seminal contribution to the establishment of essential ethical guidelines specifically designed for the fields of sports medicine and exercise science. This article charts a clear course for researchers, clinicians, and policymakers by integrating these ethical principles at the heart of our scholarly and clinical activities. Consequently, it envisions a future where the principles of research integrity and ethical responsibility consistently inform every scientific discovery and every clinical engagement.

Introduction: Despite the progress in the management of the pandemic caused by COVID-19, it is necessary to continue exploring and explaining how this situation affected the athlete population around the world to improve their circumstances and reduce the negative impact of changes in their lifestyle conditions that were necessitated due to the pandemic. The aim of this study was to analyze the moderating influence of physical activity (PA) and dietary habits on the impact of the COVID-19 pandemic experience on sleep quality in elite and amateur athletes.Materials and methods: A total of 1,420 elite (40.1%) and amateur (59.9%) athletes (41% women; 59% men) from 14 different countries participated in a cross-sectional design study. Data were collected using a battery of questionnaires that identified sociodemographic data, sleep quality index, PA levels, dietary habits, and the athletes' perception of their experience during the COVID-19 pandemic. Means and standard deviations were calculated for each variable. The analysis of variances and the correlation between variables were carried out with non-parametric statistics. A simple moderation effect was calculated to analyze the interaction between PA or dietary habits on the perception of the COVID-19 experience effect on sleep quality in elite and amateur athletes.Results: The PA level of elite athletes was higher than amateur athletes during COVID-19 (p < 0.001). However, the PA level of both categories of athletes was lower during COVID-19 than pre-COVID-19 (p < 0.01). In addition, amateurs had a higher diet quality than elite athletes during the pandemic (p = 0.014). The perception of the COVID-19 experience as controllable was significantly higher (p = 0.020) among elite athletes. In addition, two moderating effects had significant interactions. For amateur athletes, the PA level moderated the effect of controllable COVID-19 experience on sleep quality [F_(3,777) = 3.05; p = 0.028], while for elite athletes, the same effect was moderated by dietary habits [F_(3,506) = 4.47, p = 0.004].Conclusion: Elite athletes had different lifestyle behaviors compared to amateurs during the COVID-19 lockdown. Furthermore, the relevance of maintaining high levels of PA for amateurs and good quality dietary habits by elite athletes was noted by the moderating effect that both variables had on the influence of the controllable experience during the COVID-19 pandemic on sleep quality.

Background: Although several studies have shown that the Coronavirus Disease 2019 (COVID-19) lockdown has had negative impacts on mental health and eating behaviors among the general population and athletes, few studies have examined the long-term effects on elite and sub-elite athletes. The present study aimed to investigate the long-term impact of COVID-19 lockdown on mental health and eating behaviors in elite versus sub-elite athletes two years into the pandemic. A cross-sectional comparative study was conducted between March and April 2022, involving athletes from 14 countries, using a convenient non-probabilistic and snowball sampling method. A total of 1420 athletes (24.5 ± 7.9 years old, 569 elites, 35% women, and 851 sub-elites, 45% women) completed an online survey-based questionnaire. The questionnaire included a sociodemographic survey, information about the COVID-19 pandemic, the Depression, Anxiety and Stress Scale—21 Items (DASS-21) for mental health assessment, and the Rapid Eating Assessment for Participants (REAP-S) for assessing eating behavior. Results: The results showed that compared to sub-elite athletes, elite athletes had lower scores on the DASS-21 (p = .001) and its subscales of depression (p = .003), anxiety (p = .007), and stress (p < .001), as well as a lower REAP-S score indicating lower diet quality (p = .013). Conclusion: In conclusion, two years into the pandemic, elite athletes were likelier to have better mental health profiles than sub-elite athletes but surprisingly had lower diet quality.

Background: Monitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes (RESTQ-Sport) were analyzed.Methods: A cross-sectional study was carried on with 461 athletes (61% women and 39% men), 17.95 (±1.2) years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States (POMS) were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress (general and sport) and two recovery (general and sport) dimensions, and last, the concurrent validation with the POMS was carried on.Results: Significant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate (p < 0.05).Conclusion: The recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes.

La pandemia por COVID-19 tuvo gran impacto sobre la salud mental de la población universitaria, por lo que gestionar alternativas para adaptarse resulta fundamental. Objetivo. El propósito del estudio fue analizar el efecto moderador de la actividad física (AF) sobre los niveles de ansiedad generados por las vivencias durante la pandemia por COVID-19 en estudiantes universitarios. Método. Se realizó un estudio transversal, correlacional-explicativo en estudiantes universitarios (n = 922; 36.66% hombres y 63.34% mujeres; 19.97 ±2.92 años). Se aplicó un cuestionario ad hoc para medir el miedo al COVID-19, así como el CUXOS-D para los niveles de ansiedad y el IPAQ-s para evaluar la AF. Se realizaron análisis descriptivos, inferenciales y de moderación, además del factorial exploratorio y confirmatorio para el CUXOS-D. Resultados. Se observa la influencia del miedo al COVID-19 sobre los niveles de ansiedad cognitiva, la cual es moderada por los niveles de AF alta (F [3,918] = 21.58; p < .001). Asimismo, se observa que las mujeres perciben mayor ansiedad y realizan menor AF que los hombres. El análisis factorial del CUXOS-D fue satisfactorio. Conclusión. La AF puede tener efectos positivos que moderen el impacto generado por el COVID-19 sobre la ansiedad en la comunidad universitaria. The COVID-19 pandemic had a great impact on the mental health of the university population, so managing alternatives to adapt is essential. Objective. The purpose of the study was to analyze the moderating effect of physical activity (PA) on the anxiety levels generated by the experiences during the COVID-19 pandemic in university students. Method. A cross-sectional, correlational-explanatory study was carried out in university students (n = 922; 36.66% men and 63.34% women; 19.97 ± 2.92 years). An ad hoc questionnaire was applied to measure fear to COVID-19, as well as the CUXOS-D for anxiety levels and the IPAQ-s to assess PA. Descriptive, inferential and moderation analyzes were performed, in addition to the exploratory and confirmatory factorial for the CUXOS-D. Results. The influence of fear to COVID-19 on cognitive anxiety levels is observed, which is moderated by high PA levels (F [3,918] = 21.58; p <.001). Likewise, it is observed that women perceive greater anxiety and perform less PA than men. The factor analysis of the CUXOS-D was satisfactory. Conclusion. Physical activity can have positive effects that moderate the impact generated by COVID-19 over anxiety in the university community.
