Resumen Introducción : Las diferentes modificaciones estructu rales que han sido descritas en el corazón del deportista de alto rendimiento dependen de factores como la edad, el género, el tipo de deporte, la intensidad y el tiempo dedicados al entrenamiento. Objetivos : Evaluación de atletas de élite por medio de la ecocardiografía para la descripción de la estructura y la función cardíacas, y la comparación entre deportistas de resistencia cardiorrespiratoria y el resto de los deportistas. Métodos : Realizamos el examen ecocardiográfico en 224 deportistas de élite, 96 mujeres y 128 varones con edades de 15 a 38 años (21.7±5.3 años) y se dividieron en 2 grupos: "Grupo de Resistencia" (resistencia cardiorres piratoria) y "Grupo de no Resistencia" el cual incluyó al resto de los deportes. Se realizó la comparación univaria da de 14 variables ecocardiográficas entre los dos grupos. Resultados : En los hombres se identificaron valores estadísticamente significativos más altos en el grupo de resistencia para septum interventricular, pared posterior, grosor parietal relativo, índice de masa del ventrículo iz quierdo y aurícula izquierda. En las mujeres, el grupo de resistencia tuvo valores de frecuencia cardíaca más bajos con diámetro diastólico e índice de masa del ventrículo izquierdo, significativamente mayores. Conclusiones : La mayoría de las variables ecocar diográficas mostró valores mayores en los atletas de resistencia. En los hombres del Grupo de Resistencia, predominó la hipertrofia excéntrica con mayor incre mento en el grosor parietal y del diámetro de la aurícula izquierda, mientras que en las mujeres las variables indi caron hipertrofia excéntrica a expensas de un aumento del diámetro del ventrículo izquierdo, sin incremento del grosor parietal.

Abstract Introduction : The different structural modifications that have been described in the heart of the high-per formance athlete depend on factors such as age, gender, type of sport, and the intensity and time dedicated to training. Objectives : Evaluation of elite athletes through echo cardiography for the description of cardiac structure and function, and the comparison between athletes with cardiorespiratory endurance and the rest of the athletes. Methods : We performed the echocardiographic ex amination in 224 elite athletes, 96 women and 128 men aged 15 to 38 years (21.7±5.3 years) and they were di vided into 2 groups: "Endurance Group" (cardiorespira tory endurance) and "Non-Endurance Group" which included the rest of the sports. Univariate comparison between the two groups was performed by measuring 14 echocardiographic variables. Results : In men, statistically significant higher values were identified in the endurance group for interventricu lar septum, left ventricular posterior wall, relative wall thickness (RWT), left ventricular mass index and left atrial dimension. In women, the endurance group had signifi cantly lower heart rate values, and significantly higher left ventricular diastolic dimension with normal RWT. Conclusions : Most of the echocardiographic vari ables showed higher sample means in the endurance athletes. In the subgroup of men from the Endurance Group, eccentric hypertrophy prevailed with a greater increase in wall thickness, as well as in the diameter of the left atrium, while in women the variables indicated eccentric hypertrophy at the expense of an increase in left ventricle diameter, without increased wall thickness.

Cheese positively affects serum osteocalcin levels, bone turnover markers and bone mineral density in cross-country skiers: a dose-response study

Background: Vitamin K2-rich Jarlsberg Cheese is demonstrated to increase Osteocalcin and bone turnover markers in fertile women. The impact on endurance-trained young cross-country skiers (XCS)with elevated bone turnover remains unclear. Purpose of study was to estimate the optimal daily efficacy dose of Jarlsberg cheese to increase serum Osteocalcin level in young female and male XCS and estimate the Jarlsberg effect on bone turnover markers (BTMs)and bone mineral density(BMD).Methods: In a parallel group study consisting of three design levels, 10 female and 10 male XCS were included, using Response Surface Pathway design. Blood samples were taken at each level for measurements of Osteocalcin, vitamin K2, BTMs and other biochemical parameters. Resting metabolic rate(RMR), BMD, VO2max and muscle strength were measured at start and at the end of the study.Results:The Osteocalcin development with increasing dose of Jarlsberg cheese was almost parallel in both sexes. These variables were reduced significantly from baseline during the first two design levels but increased above baseline by the end of the study. BTMs decreased significantly during the first and second level but increased during the third level. Total and L1-L4 BMD, s-phosphate, s-urea, RMR, muscle strength and Peak VO2increased significantly while s-calcium and s-magnesium decreased.Conclusions:Estimated OED of Jarlsberg cheese was 73 and 84 g/day for females and male athletes, respectively. The development in OC, BTMs and BMD suggest an antiresorptive and perhaps anabolic effect of Jarlsberg Cheese on bone tissue. VO2 max, RMR and muscular strength development indicated an anabolic situation

Integrated analysis of health dynamics in esports: injury profiles, intervention strategies, and health optimization protocols

The rapidly expanding realm of Electronic Sports (eSports) has captivated global attention, blurring the lines between virtual entertainment and traditional athletics. As participation in eSports continues to rise, these competitive gaming platforms are increasingly recognized as legitimate sports. However, with this surge in participation, there's a simultaneous increase in the susceptibility to health hazards, spanning both physical and psychological domains. Musculoskeletal injuries, caused by extended sedentary postures and repetitive motions, afflict eSports athletes, resulting in discomfort in the wrists and hands, alongside back and neck problems. The prolonged exposure to screens predisposes participants to vision-related concerns, highlighting the imperative of addressing ocular health within the eSports community. Simultaneously, the intense cognitive demands and competitive pressures exacerbate mental health challenges, resulting in depression and anxiety among players. Similar to traditional athletes, eSports competitors need appropriate protocols to minimize injury risks, alongside access to medical intervention to manage potential health hazards. This review comprehensively analyses the health dynamics of eSports, elucidating injury profiles, intervention strategies, and health optimization protocols essential for safeguarding the well-being of eSports athletes and enhancing awareness within the eSports community.

El propósito de este estudio fue evaluar la relación entre el rendimiento anaeróbico y la personalidad Grit en taekwondistas estadounidenses, su grado de influencia, así como las diferencias que puedan existir entre sexos. Este estudio tuvo una metodología cuantitativa, descriptiva-correlacional, realizada en una población de (n=121) taekwondistas, vinculados a la USAT. La personalidad Grit fue medida mediante la escala Grit, y el rendimiento anaeróbico a través de la prueba del sprint anaeróbico basado en la carrera (Rast). De acuerdo con los resultados se pudo identificar en hombres, una correlación positiva y significativa entre la capacidad y potencia anaeróbica con el Grit (p<0.005 y p<0.007 respectivamente). Asimismo, estas dos variables se relacionaron significativamente con el Grit (p<0.001) en el total de la muestra. En el caso de las mujeres, no hubo relaciones significativas. El índice de fatiga no presentó correlaciones significativas. La personalidad Grit influyó hasta un 14% en la capacidad y potencia anaeróbica en hombres (p<0.001 y p<0.002, respectivamente) y un 12% en estos dos mismos aspectos para la muestra total (p<0.000 en ambos casos). Finalmente, los hallazgos indican una relación entre la potencia, capacidad anaeróbica con la personalidad Grit en hombres y en el total de la muestra, con una influencia significativa del Grit en el rendimiento anaeróbico. No se encontraron tales relaciones en mujeres. Aunque no se hallaron diferencias significativas por sexo en el Grit, capacidad y potencia anaeróbica, sí que se encontró en el índice de fatiga, indicando una disparidad en la resistencia a la fatiga entre sexos.

The purpose of this study was to assess the relationship between anaerobic performance and Grit personality in American taekwondo practitioners, its degree of influence, as well as any differences that may exist between genders. This study employed a quantitative, descriptive-correlational methodology, conducted on a population of (n=121) taekwondo practitioners affiliated with the USAT. Grit personality was measured using the Grit Scale, and anaerobic performance was assessed through the Anaerobic Sprint Test based on running (Rast). According to the results, a positive and significant correlation between anaerobic capacity and power with Grit was identified in men (p<0.005 and p<0.007 respectively). Likewise, these two variables were significantly related to Grit (p<0.001) in the total sample. In the case of women, there were no significant relationships. The fatigue index showed no significant correlations. Grit personality influenced up to 14% in anaerobic capacity and power in men (p<0.001 and p<0.002, respectively) and 12% in these two aspects for the total sample (p<0.000 in both cases). Finally, the findings indicate a relationship between power, anaerobic capacity, and Grit personality in men and the total sample, with a significant influence of Grit on anaerobic performance. Such relationships were not found in women. Although no significant gender differences were found in Grit, anaerobic capacity, and power, differences were found in the fatigue index, indicating a disparity in fatigue resistance between genders.

Fue así que durante el ejercicio y antes de la ingesta del bebible, se observaron fluctuaciones en los niveles de glucosa, con un 5% persistiendo en hiperglucemia y un 25% en hipoglucemia. Una hora posterior de la actividad física y del consumo del bebible, se registraron una mejora significativa en los niveles de glucosa, con un 4% de los deportistas presentando hipoglucemia y un 80% alcanzando niveles de normoglucemia. CONCLUSIONES: luego al consumo del bebible nutricional y del tiempo de absorción de los nutrientes, la glucemia del 80% de los participantes fue de normoglucemia. En 270mL aportó 218,1 kcal ­ 13,52 g de proteínas ­ 1,56 g de grasa ­ 38g de hidratos de carbono y 0,73 g de fibra cruda, sin embargo, hace falta ampliar la muestra para afirmar este efecto

OBJECTIVE: to determine basal blood glucose levels before and after consumption of a nutritional beverage in athletes from the High-Performance Center of the Autonomous Municipal Government of La Paz during the year 2019. MATERIAL AND METHODS: in this quasi-experimental before-and-after study, changes in blood glucose levels were analyzed in 20 athletes following a 30-minute exercise protocol, followed by the intake of a nutritional beverage. Subsequently, blood glucose levels were measured at three points of time: at rest, immediately post-exercise, and one hour after the intervention. The study aimed to explore the influence of the nutritional beverage on glycemic regulation and its potential effects. RESULTS: analysis of baseline blood glucose levels revealed a balanced distribution between hyperglycemia and hypoglycemia in 50% of the athletes. Besides, during exercise and before beverage intake, fluctuations in glucose levels were observed, with 5% persisting with hyperglycemia and 25% with hypoglycemia. One hour after physical activity and beverage intake, a significant improvement in glucose levels was recorded in 80% achieving normoglycemia, and 4% of athletes presenting hypoglycemia. CONCLUSIONS: after consuming the nutritional beverage and nutrient absorption time, 80% of participants exhibited normoglycemia. The beverage provided 218.1 Kcal, 13.52 g of protein, 1.56 g of fat, 38 g of carbohydrates, and 0.73 g of crude fiber per 270 mL. However, further sample expansion is needed to confirm this effect.

Celiaquía y rendimiento deportivo. Una revisión sistemática / Celiac disease and sports performance. Systematic review

Introducción: La celiaquía es una patología multisistémica con base autoinmune que provoca una reacción a la proteína gluten encontrada en alimentos como o trigo, centeno, triticale, cebada, espelta y avena. Los síntomas más comunes de la celiaquía son la pérdida de peso, pérdida de apetito y fatiga general entre otros. A consecuencia de estos síntomas el rendimiento deportivo puede verse afectado. Objetivo: Para comprender como la celiaquía impacta en el rendimiento de los deportistas, el objetivo de este estudio es realizar una revisión sistemática relacionada con el rendimiento deportivo en personas celíacas. Materiales y métodos: Para ello, se utilizó la siguiente frase final de búsqueda: "Celiac" AND "Sport" AND "Performance", que fue introducida por igual en las bases de datos: Web of Science, Scopus y PubMed. Resultados: Los resultados muestran la existencia de escasos documentos relacionados con el objeto de estudio (n=11), dónde se muestra una variabilidad de tipos de diseño en los trabajos seleccionados. Por otro lado, se extrae que la única solución para mantener un adecuado rendimiento deportivo en una persona celiaca es llevar una dieta libre de gluten de por vida. Conclusiones: Los documentos seleccionados subrayan la importancia de que los deportistas con enfermedad celiaca mantengan una dieta sin gluten de manera constante a lo largo de su vida. Debido a la escasez de estudios relacionados con la temática, se recomienda aumentar el número de investigaciones relacionadas con el objeto de estudio, con la finalidad de mejorar los estilos y hábitos de vida de los deportistas celíacos(AU)

Introduction: Celiac disease is a multisystem autoimmune disorder that triggers a reaction to the protein gluten found in foods such as wheat, rye, triticale, barley, spelt, and oats. The most common symptoms of coeliac disease are weight loss, loss of appetite and general fatigue among others. As a result of these symptoms, athletic performance may be affected. Objetive: To understand how celiac disease impacts athletes' performance, the aim of this study is to conduct a systematic review related to sports performance in individuals with celiac disease. Materials and method: To do so, the following search phrase was used: "Celiac" AND "Sport" AND "Performance", which was entered equally in the following databases: Web of Science, Scopus and PubMed. Results: The results show the existence of few documents related to the object of study (n=11), where a variability of design types is shown in the selected works. On the other hand, the only solution to maintain adequate sports performance in a person with coeliac disease is to follow a gluten-free diet for life. Conclusions: The selected documents emphasize the importance of athletes with celiac disease maintaining a gluten-free diet consistently throughout their lives. Due to the scarcity of studies related to this topic, it is recommended to increase the number of research studies on this subject in order to improve the lifestyles and habits of athletes with celiac disease(AU)

Upper and lower limb bone mass accrual in adolescent footballers across a short period of training and competition

Abstract Objectives: To analyze bone mineral content (BMC) and area bone mineral density (aBMD) accrual in adolescent male footballers who started their first football season. Methods: 17 athletes (14.8 ± 0.4 years) were monitored across 15 weeks of football training. Participants were evaluated for somatic maturation (HPHV), BMC, and aBMD at three time points: before (M1) and after (M2) a preparatory phase, and at the end of the competitive phase (M3). BMC and aBMD were measured using DXA scans. Participants were divided into groups according to maturation status (circa-PHV and post-PHV), and the amount of accumulated training load (median split). Results: A significant effect (12.1 g/week, standard error (SE) = 2.6 g/week) was observed for lower limbs BMC across the three time points. There were no significant effects of time for upper limbs BMC. There was a significant effect of time for total body aBMD (0.007, SE = 0.003 g/cm2/week) across the three time points. Adolescents at post-PHV had a significant 245.6 g (SE = 56.1 g) higher BMC compared to adolescents at circa-PHV. No significant effects were observed for the accumulated training load. Conclusion: Systematic football training, even during the growth spurt, has a positive impact on adolescent bone markers despite the accumulated training load and maturation.

Small-Sided Games vs. High-Intensity Interval Training on Body Composition of Female Handball Players / Juegos Reducidos vs Entrenamiento Interválico de Alta Intensidad sobre la Composición Corporal de Jugadoras de Balonmano

SUMMARY: The purpose of this study was to compare the effects of different training programs based on small-sided games (SSG) and high-intensity interval training (HIIT) on the body composition of female handball players. A total of 45 female handball players (age: 16.13±0.89 years; training experience: 6.18±1.33 years) were assigned to three groups: game group (GG; N = 15), running group (RG; N = 15), and control group (CON; N = 15). The training programs lasted eight weeks, with two training sessions per week. The GG performed three vs. three small-sided games on a 20 m x 20 m court; the RG performed 15 s HIIT running followed by 15 s of active recovery; the CON group maintained regular handball training. Regardless of the group assignment, all participants were measured for each of the following variables: Body height, body mass, fat-free mass, fat mass, muscle mass, intracellular water, and extracellular water. The results demonstrate significant differences (p0.01) in muscle mass. The GG showed significant (p<0.001) greater improvement in these body composition variables than RG and CON. Body composition variables improved with GG, moving from 2.04 % in fat mass to 1.3 % in extracellular water. In the RG, results show significant improvements (p<0.001) only in intra- and extracellular water. The CON shows improvements in fat-free mass, muscle mass, intracellular water, and extracellular water. To conclude, eight weeks of SSG in handball provide better changes in body composition compared to HIIT 15 s - 15 s and handball training alone.

El propósito de este estudio fue comparar los efectos de diferentes programas de entrenamiento basados en juegos reducidos (SSG) y entrenamiento interválico de alta intensidad (HIIT) sobre la composición corporal de jugadoras de balonmano. Un total de 45 jugadoras de balonmano (edad: 16,13 ± 0,89 años; experiencia de entrenamiento: 6,18 ± 1,33 años) fueron asignadas a tres grupos: grupo de juego (GG; N = 15), grupo de carrera (RG; N = 15) y grupo de control (CON; N = 15). Los programas de formación duraron ocho semanas, con dos sesiones de formación por semana. El GG realizó partidos reducidos de tres contra tres en una cancha de 20 x 20 m; el RG realizó 15 s de carrera HIIT seguidos de 15 s de recuperación activa; El grupo CON mantuvo un entrenamiento regular de balonmano. Independientemente de la asignación de grupo, a todos los participantes se les midió cada una de las siguientes variables: altura corporal, masa corporal, masa libre de grasa, masa grasa, masa muscular, agua intracelular y agua extracelular. Los resultados demuestran diferencias significativas (p0,01) en la masa muscular. El GG mostró una mejora significativa (p<0,001) mayor en estas variables de composición corporal que RG y CON. Las variables de composición corporal mejoraron con GG, pasando de un 2,04 % en masa grasa a un 1,3 % en agua extracelular. En el RG, los resultados mostraron mejoras significativas (p<0,001) sólo en el agua intra y extracelular. El CON indicó mejoras en la masa magra, la masa muscular, el agua intracelular y el agua extracelular. En conclusión, ocho semanas de SSG en balonmano proporcionan mejores cambios en la composición corporal en comparación con el HIIT de 15 s - 15 s y el entrenamiento de balonmano solo.

Estado de los exdeportistas en situaciones de discapacidad físico-motora: la necesidad del desentrenamiento deportivo

El desentrenamiento deportivo es un proceso esencial, para garantizar una transición fluida a los exdeportistas, de un periodo prolongado de vida deportiva a una vida posdeportiva. En este sentido, la investigación tuvo como objetivo determinar el estado actual que presenta el proceso de desentrenamiento de exdeportistas en situaciones de discapacidad físico-motora, en la provincia El Oro. Para el estudio, se seleccionaron, a través de un muestreo aleatorio simple, a ocho exdeportistas en situaciones de discapacidad físico-motora. Los exdeportistas tienen una experiencia promedio en el ámbito deportivo de 8.38 (± 4.92) años. También se interactuó con entrenadores, profesores de Educación Física, médicos, psicológicos, familiares y directivos. Se aplicaron encuestas a todos los participantes en el estudio, y solo a los exdeportistas pruebas antropométricas, médicas, de laboratorios y funcionales. Entre los resultados obtenidos, se pudo identificar que existen limitaciones para afrontar el desentrenamiento como un proceso formativo, pedagógico y social, que los deportistas retirados no cuentan con información suficiente sobre este proceso y tienen carencia de proyectos significativos, por lo que se revela la necesidad de diseñar un proceso de desentrenamiento, ajustado a sus necesidades específicas.

O destreinamento esportivo é um processo essencial para garantir uma transição tranquila para ex-atletas de um período prolongado de vida esportiva para uma vida pós-esportiva. Nesse sentido, a pesquisa teve como objetivo determinar o estado atual do processo de destreinamento de ex-atletas em situações de deficiência físico-motora na província de El Oro. Para o estudo, foram selecionados oito ex-atletas com deficiências físico-motoras por meio de amostragem aleatória simples. Os ex-atletas têm uma média de 8,38 (± 4,92) anos de experiência em esportes. Também interagimos com treinadores, professores de educação física, médicos, psicólogos, familiares e gerentes. Foram aplicados questionários a todos os participantes do estudo, e testes antropométricos, médicos, laboratoriais e funcionais foram aplicados somente aos ex-atletas. Entre os resultados obtidos, foi possível identificar que há limitações em lidar com o destreinamento como processo formativo, pedagógico e social, que os atletas aposentados não têm informações suficientes sobre esse processo e que carecem de projetos significativos, revelando, assim, a necessidade de se desenhar um processo de destreinamento ajustado às suas necessidades específicas.

Sports detraining is an essential process to guarantee a smooth transition for former athletes from a prolonged period of sports life to a post-sports life. In this sense, the objective of the research was to determine the current state of the detraining process of former athletes in situations of physical-motor disability, in the province of El Oro. For the study, through simple random sampling, eight former athletes in situations of physical-motor disability were selected. Former athletes have an average experience in the sports field of 8.38 (± 4.92) years. There was also interaction with coaches, Physical Education teachers, doctors, psychologists, family members and managers. Surveys were administered to all participants in the study, and anthropometric, medical, laboratory and functional tests were administered only to former athletes. Among the results obtained, it was possible to identify that there are limitations to face detraining as a training, pedagogical and social process, that retired athletes do not have sufficient information about this process and have a lack of significant projects, which is why it is revealed the need to design a detraining process, tailored to their specific needs.

RESUMEN Objetivo: Describir los cambios percibidos en hábitos de alimentación, composición corporal, condición física y psicológica de deportistas universitarios durante la cuarentena por Covid-19 en 2020. Materiales y métodos: Estudio transversal, de fuente de información secundaria; 403 deportistas universitarios diligenciaron una encuesta en línea en el segundo semestre de 2020. Se utilizó la estadística descriptiva para analizar los datos, para determinar asociación entre las variables de interés: tipo de deporte, sexo y Covid-19 se utilizó la prueba de significancia estadística Chi X2 de Pearson <0,05. Resultados: Del total de deportistas, el 53,3 eran hombres. La mayoría practicaba deportes individuales (55,3 %). Alrededor del 89 % de atletas no presentó Covid-19. El 59,8 % sintió que el peso empeoró, siendo mayor en los deportes individuales (p= 0,005). Una proporción mayor de mujeres recibió asesoría por parte de un entrenador y de redes sociales (62,7 %) y 7 de cada 10 hombres complementaba su entrenamiento con información proveniente de redes sociales (p=0,001). Las características psicológicas fueron las que mostraron mayores diferencias significativas según sexo y el tipo de deporte. Conclusión: La cuarentena por Covid-19 está asociada con cambios desfavorables en los deportistas universitarios; específicamente, se percibieron cambios en los hábitos de alimentación con un aumento en la cantidad de alimentos de baja calidad nutricional y alta densidad calórica, cambios negativos en el peso y peor condición física. Los deportes individuales se vieron más afectados frente a los deportes de conjunto; en lo psicológico se resalta la mala adaptación a la cuarentena con sentimientos de soledad, ansiedad y mal estado de ánimo, donde las mujeres fueron las más afectadas.

ABSTRACT Objetive: Describe the perceived changes in eating habits, body composition, physical and psychological condition of university athletes during the quarantine by Covid-19, in the year 2020. Materials and methods: Cross-sectional study, from a secondary data source, 403 universitary athletes answered an online survey on 2020's second semester. Descriptive statistics was used to analyze data, Pearson's Chi X2 <0,05 test was used to determine association between variables of interest: Sport type, sex and Covid-19.

Conclusion: The Covid-19 quarantine is associated with unfavorable changes in university athletes, specifically changes in eating habits were perceived with an increase in the amount of foods of low nutritional quality, negative changes in weight, worse physical condition, where the individual sports were more affected compared to group sports, feelings of loneliness, anxiety and bad mood, where women were the most affected.

Exercise addiction: a comparison between runners, cyclists, swimmers, and triathletes / Dependência ao exercício: uma comparação entre corredores, ciclistas, nadadores e triatletas / Adicción al ejercicio: una comparación entre corredores, ciclistas, nadadores y triatletas

The aim of the present study was to evaluate and compare exercise addiction (EA) between runners, cyclists, swimmers, and triathletes. Took part in this study 39 runners, 32 cyclists, 30 swimmers and 38 triathletes. Exercise Dependence Scale (EDS), and the Exercise Addiction Inventory (EAI) was used to evaluate the EA and classified the participants into: at-risk for EA, nondependent-symptomatic, and nondependent-asymptomatic. Most participants were classified as nondependent symptomatic for EA. The EDS total score was significantly lower in the swimmers compared to the cyclists and triathletes and the EAI total score was significantly higher for cyclists compared to runners. Therefore, in both instruments, the majority of participants was nondependent symptomatic for EA.

Orthopedic sports injuries: advanced imaging modalities, return-to-play criteria, and injury prevention

Orthopaedic sports injuries encompass a wide range of musculoskeletal conditions resulting from the physical demands of athletic activities. These injuries can vary from acute, such as sprains and fractures, to chronic overuse syndromes like tendinopathies. Prevalent due to the global enthusiasm for sports, they affect bones, muscles, tendons, ligaments, and joints. The etiology of these injuries is multifactorial, stemming from biomechanical stressors, training methods, genetics, and environmental conditions. Advanced imaging modalities like magnetic resonance imaging and Computed tomography have revolutionized the assessment and diagnosis of these injuries, aiding in treatment decisions and return-to-play criteria. Injury prevention is paramount and involves understanding intrinsic (athlete-related) and extrinsic (environmental) risk factors. Strategies include pre-participation screening, strength and conditioning programs, biomechanical analysis, neuromuscular training, proper equipment use, rule changes, education, and creating a safety-conscious culture. Effective prevention reduces the burden of these injuries. Treatment strategies range from conservative approaches to surgery, depending on the type and severity of the injury. Emerging trends in sports medicine, including biologic therapies and telemedicine, offer promising avenues for improved diagnosis and recovery. The holistic approach to orthopaedic sports injuries encompasses prevention, diagnosis, and treatment, ensuring athletes' well-being and longevity in their chosen sports.

Mapeamento do Potencial da Superfície Corporal durante a Despolarização Ventricular em Atletas com Intervalo PQ Prolongado após Exercício / Body Surface Potential Mapping during Ventricular Depolarization in Athletes with Prolonged PQ Interval after Exercise

Resumo Fundamento: O prolongamento do intervalo PQ, geralmente associado a um atraso na condução atrioventricular, pode estar relacionado a alterações na propagação do impulso intraventricular. Objetivo: Avaliar, por meio do mapeamento do potencial de superfície corporal (BSPM), o processo de despolarização ventricular em atletas com intervalos PQ prolongados em repouso e após o exercício. Métodos: O estudo incluiu 7 esquiadores cross-country com intervalo PQ superior a 200 ms (grupo PQ Prolongado) e 7 com intervalo PQ inferior a 200 ms (grupo PQ Normal). O BSPM de 64 derivações unipolares do tronco foi realizado antes (Pré-Ex) e após o teste ergométrico de bicicleta (Pós-Ex). Mapas equipotenciais da superfície corporal foram analisados durante a despolarização ventricular. O nível de significância foi de 5%. Resultados: Comparado com atletas com PQ Normal, o primeiro e o segundo períodos de posição estável dos potenciais cardíacos na superfície do tronco foram mais longos, e a formação da distribuição de potencial "sela" ocorreu mais tarde, no Pré-Ex, nos atletas com PQ Prolongado. No Pós-Ex, o grupo PQ Prolongado apresentou um encurtamento do primeiro e segundo períodos de distribuições de potencial estáveis e uma diminuição no tempo de aparecimento do fenômeno "sela" em relação ao Pré-Ex (para valores próximos aos do Normal -Grupo PQ). Além disso, no Pós-Ex, a primeira inversão das distribuições de potencial e a duração total da despolarização ventricular em atletas com PQ Prolongado diminuíram em comparação com o Pré-Ex e com valores semelhantes em atletas com PQ Normal. Em comparação com atletas com PQ Normal, a segunda inversão foi mais longa no Pré-Ex e Pós-Ex em atletas com PQ Prolongado. Conclusão: Atletas com PQ prolongado apresentaram diferenças significativas nas características temporais do BSPM durante a despolarização ventricular, tanto em repouso quanto após o exercício, em comparação com atletas com PQ normal.

Abstract Background: Prolongation of the PQ interval, generally associated with an atrioventricular conduction delay, may be related to changes in intraventricular impulse spreading. Objective: To assess, using body surface potential mapping (BSPM), the process of ventricular depolarization in athletes with prolonged PQ intervals at rest and after exercise. Methods: The study included 7 cross-country skiers with a PQ interval of more than 200 ms (Prolonged-PQ group) and 7 with a PQ interval of less than 200 ms (Normal-PQ group). The BSPM from 64 unipolar torso leads was performed before (Pre-Ex) and after the bicycle exercise test (Post-Ex). Body surface equipotential maps were analyzed during ventricular depolarization. The significance level was 5%. Results: Compared to Normal-PQ athletes, the first and second periods of the stable position of cardiac potentials on the torso surface were longer, and the formation of the "saddle" potential distribution occurred later, at Pre-Ex, in Prolonged-PQ athletes. At Post-Ex, the Prolonged-PQ group showed a shortening of the first and second periods of stable potential distributions and a decrease in appearance time of the "saddle" phenomenon relative to Pre-Ex (to the values near to those of the Normal-PQ group). Additionally, at Post-Ex, the first inversion of potential distributions and the total duration of ventricular depolarization in Prolonged-PQ athletes decreased compared to Pre-Ex and with similar values in Normal-PQ athletes. Compared to Normal-PQ athletes, the second inversion was longer at Pre-Ex and Post-Ex in Prolonged-PQ athletes. Conclusion: Prolonged-PQ athletes had significant differences in the temporal characteristics of BSPM during ventricular depolarization both at rest and after exercise as compared to Normal-PQ athletes.

Clinical outcomes of hip arthroscopic surgery in treating femoral acetabular impingement for athletes / 中华骨科杂志

Objective:To investigate the clinical efficacy of arthroscopic surgery for the treatment of femoral acetabular impingement (FAI) in athletes.Methods:A total of 18 FAI athletes (athlete group) who underwent hip arthroscopy in the Department of Sports Medicine, Peking University Third Hospital from April 2014 to June 2021 were retrospectively analyzed, including 12 males and 6 females, aged 20.44±3.45 years (range, 15-27 years). According to gender, age, body mass index and follow-up time, 36 non-athlete FAI patients (non-athlete group) were matched at a ratio of 1∶2 by propensity score matching method. There were 18 males and 18 females, aged 20.81±4.68 years (range 14-31 years). The hip pain visual analogue scale (VAS), modified Harris hip score (mHHS), hip outcome score-activity of daily living scale (HOS-ADL) and hip outcome score-sports scale (HOS-SS) scores were compared between the two groups before and after surgery. The minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) were also compared between the two groups.Results:All patients successfully completed the surgery and were followed up for 33.56±19.20 months (range, 24-77 months). The VAS score at the last follow-up decreased from 6.22±1.52 points before surgery to 1.28±1.67 points in the athletes group, and decreased from 6.28±1.37 points before surgery to 1.67±1.69 points in the non-athletes group. There was no significant difference between the two groups ( P>0.05). The mHHS score at the last follow-up increased from 65.53±12.90 points before surgery to 92.28±13.59 points in the athletes group, and increased from 61.01±11.96 points before surgery to 86.82±11.98 points in the non-athletes group. There was no significant difference between the two groups ( P>0.05). The HOS-ADL score at the last follow-up increased from 72.77±18.86 points before surgery to 94.00±11.36 points in the athletes group, and increased from 70.35±13.12 points before surgery to 90.78±9.36 points in non-athletes group. There was no significant difference between the two groups ( P>0.05). The HOS-SS score at the last follow-up increased from 49.77±22.93 points before surgery to 87.28±17.62 points in the athletes group, and increased from 44.08±19.66 before surgery to 72.57±20.16 in the non-athletes group. The HOS-SS scores in the athletes group at the last follow-up were higher than those in the non-athletes group ( P<0.05). Furthermore, 61% (11/18) in the athletes group achieved MCID in HOS-ADL after surgery, which was lower than the non-athletes group's 81% (31/36), with a statistically significant difference (χ 2=4.339, P=0.037). Conclusion:Hip arthroscopy in the treatment of FAI in athletes can achieve satisfactory pain relief and motor function.

Relationship among subjective well-being,depression-anxiety-stress and dispositional mindfulness in professional athletes / 中国心理卫生杂志

Objective:To explore the relationship among subjective well-being and depression-anxiety-stress and dispositional mindfulness in professional athletes,and the role of cognitive fusion and experiential avoidance and age in the relationship.Methods:Totally 423 professional athletes were selected and assessed with the Satisfac-tion with Life Scale(SWLS),Positive Affect Scale(PAS),Depression-Anxiety-Stress Scale(DASS-21),Five Fac-et Mindfulness Questionnaire(FFMQ),Cognitive Fusion Questionnaire(CFQ),and Acceptance and Action Ques-tionnaire-Ⅱ(AAQ-Ⅱ).Results:After controlling for gender,the FFMQ scores were positively correlated with SWB scores(β=0.35),and negatively correlated with DASS-21 scores(β=-0.40).The scores of CFQ and AAQ-Ⅱplayed a sequential mediating role in the relationship between FFMQ scores and the scores of SWB and DASS-21(β=0.04,-0.12).Age moderated the relationship between the scores of FFMQ and SWB(β=-0.01).Conclu-sion:The subjective well-being and depression-anxiety-stress may be related to dispositional mindfulness in profes-sional athletes,and age could moderate the relationship between subjective well-being and dispositional mindful-ness.
