Eating disorders are psychiatric and behavioral health pathologies of high complexity and different etiology, which can affect age groups, sexes, and ethnicities indistinctly. This study aimed to evaluate the risk of eating disorders and the possible relation with the sports profile of Colombian adolescent athletes. This was an exploratory cross-sectional quantitative study that used an online form designed with a sociodemographic questionnaire and the EAT-26 scale to determine the eating disorder risk of the object population. A total of 354 adolescent athletes participated. There were 182 men and 172 women and the mean age was 15.59 (range: 10–19 years, SD = 1.938). The participants presented a significantly low risk of eating disorders (21.2%) with no differences in prevalence between both sexes. The risk of eating disorder was related to the result of the last competition (p = 0.01), the type of sport (p = 0.032), the years of sports practice (p = 0.004), and the number of training hours a day (p = 0.011). It is relevant to recognize that adolescents and athletes are vulnerable populations regarding eating disorders. In conclusion, adolescent athletes should be the object of special attention to prevent eating disorders and their consequences on health and sports performance.

La diabetes es una enfermedad no transmisible cuya importancia epidemiológica radica en el aumento exponencial de la morbilidad y la mortalidad en todo el mundo. Se pretendió determinar la asociación entre la clasificación nutricional de los pacientes con diabetes y la influencia en el control de la patología. Estudio descriptivo transversal, en 237 participantes con diabetes, hombres y mujeres mayores de edad pertenecientes a un programa de control en dos entidades que brindan servicios de salud. El análisis estadístico de los datos se realizó con el software SPSS versión 25, con tablas de contingencia y prueba de chi cuadrado, calculando el valor de P con un intervalo de confianza del 95%. Se encontró que el 49,36% de los participantes tenía un nivel de hemoglobina glicosilada superior al 7%, el 51,89% con lipoproteínas de baja densidad mayor a 100mg/dl, el 63,71% sin practicar actividad física y el 68,3% en exceso de peso. Los hábitos de vida saludable como sana alimentación y ejercicio regular pueden ser determinantes en el control patológico de la diabetes mellitus tipo 2 pues influyen en la pérdida de peso y sus comorbilidades, factores importantes en el estado de salud de este tipo de pacientes.

Introduction Blood biomarkers are measurable metabolic products that allow objective monitoring of the training process, and their analysis provides an opportunity to improve athletic performance. Objective To evaluate blood lactate concentrations in a group of the Valle League weightlifting athletes as a tool to determine the effects of training and its direct relationship to performance during competition. Methods This is an observational cross-sectional study. Lactate levels of 32 weightlifting athletes belonging to the Valle Weightlifting League were evaluated. Blood samples were taken from the ear lobe to quantify the lactate concentration, using a Scout Lactate analyzer. Samples were taken before and after a high intensity training section consisting of four maximum repetition (MR) sports gestures, in which 5 series and 15 repetitions were performed for each sports gesture, with a rest period of 40 seconds between each exercise. The software program SPSS, version 25, was used to determine the lactate concentrations. Results An average lactate concentration 22.46 mg/dL was obtained for the athletes at rest, and an average of 98.30 mg/dL in the final lactate concentration, after high intensity exercise. Significant differences were found between the initial and final lactate concentrations. Conclusion Lactate concentration increases with physical activity; it varies from one individual to another; and it can be used as a biomarker of intensity of physical activity in the field of sports. Level of evidence; II type of study: Prognostic Studies Investigating the Effect of a Patient Characteristic on a disease outcome.

Rapid weight loss is a widespread practice in combat sports, intended to meet weight-class requirements while preserving an anatomical advantage. These strategies primarily reduce extracellular and intracellular fluid volumes by manipulating carbohydrate, sodium, and water intake, followed by rapid weight gain after the official weigh-in. This study analysed the association between raw bioelectrical impedance variables measured immediately after weigh-in and competitive outcome in amateur combat athletes. A cross-sectional analytical design was conducted with 54 athletes from boxing, Mixed Martial Arts, and Muay Thai. Measurements of resistance (R), reactance (Xc), and phase angle (PhA) were obtained under standardized conditions using a tetrapolar device. Descriptive statistics characterized the sample, and logistic regression evaluated predictors of winning or losing. Mean values for R/H (height), Xc/H, PhA/H, and Z/H reflected a dehydrated profile consistent with recent weight cutting. Only Xc/H met the regression model's entry criteria. Higher Xc/H values were associated with lower odds of winning (OR = 0.857), suggesting that athletes with lower post-weigh-in reactance/height — potentially reflecting more effective rehydration and extracellular volume restoration — were more likely to achieve victory. These findings highlight the physiological relevance of bioelectrical markers for assessing recovery and their promise as indicators of competitive readiness in combat sports.

Nterpreting, understanding, and applying statistical knowledge, presents, in many cases, some difficulties for students in the training process. For this reason, and thanks to the rise of information and communication technologies; a virtual object was developed for learning the statistical methods of Kruskal Wallis, Mann Whitney U and Wilcoxon, which are included in non-parametric statistics. The objective of this quasi-experimental design study was to apply the virtual object as a teaching-learning strategy for these three statistical methods after its creation and validation in order to support the training of students in biostatistics. The virtual learning object was evaluated by experts through the LORI instrument (tool that allows to evaluate learning objects based on nine variables), granting a quality level in the medium-high range according to the final weighting. The evaluation instrument and the comparative statistical analysis used in this process showed that the learning object is adequate for the purpose and objective set, concluding that there is a significant difference in the academic results of the students to whom this digital tool was applied.

Background/Objectives: The global population ageing has increased the prevalence of chronic diseases and disabilities, thereby affecting the quality of life of elderly adults. Exercise interventions have been proven effective in enhancing the functional capacity of this population. The aim was to assess the effect of three exercise programs on physical fitness and the coping and adaptation process in elderly adults. Methods: A quasi-experimental study was conducted with 450 adults aged 60 years or older, randomly assigned to three intervention groups. The Senior Fitness Test was used to assess physical fitness, and Roy’s Coping and Adaptation Processing Scale was used to measure coping and adaptation. The data were analyzed using linear mixed models. Results: Multimodal intervention was significantly more effective in improving muscle strength, specifically in the Sitting-Rising and Push-Up tests. However, no significant improvements in flexibility or aerobic fitness were observed. Age was a determining factor, with lower performance observed in physical tests as age increased. There were no significant improvements in the coping and adaptation process, although an overall improvement in adaptation was observed in the intermediate age ranges. Conclusions: Multimodal training emerges as the most effective intervention for improving muscle strength in elderly adults. However, a lack of improvement in flexibility and aerobic fitness may suggest the need for more specific interventions. Age negatively impacted physical performance, underscoring the importance of tailoring exercise programs to this population.
