RESUMO

BACKGROUND: Several large observational prospective studies have reported a protection by the traditional Mediterranean diet against type 2 diabetes, but none of them used yearly repeated measures of dietary intake. Repeated measurements of dietary intake are able to improve subject classification and to increase the quality of the assessed relationships in nutritional epidemiology. Beyond observational studies, randomized trials provide stronger causal evidence. In the context of a randomized trial of primary cardiovascular prevention, we assessed type 2 diabetes incidence according to yearly repeated measures of compliance with a nutritional intervention based on the traditional Mediterranean diet. METHODS: PREDIMED (''PREvención con DIeta MEDiterránea'') was a Spanish trial including 7447 men and women at high cardiovascular risk. We assessed 3541 participants initially free of diabetes and originally randomized to 1 of 3 diets: low-fat diet (n = 1147, control group), Mediterranean diet supplemented with extra virgin olive (n = 1154) or Mediterranean diet supplemented with mixed nuts (n = 1240). As exposure we used actual adherence to Mediterranean diet (cumulative average), yearly assessed with the Mediterranean Diet Adherence Screener (scoring 0 to 14 points), and repeated up to 8 times (baseline and 7 consecutive follow-up years). This score was categorized into four groups: < 8, 8-< 10, 10- < 12, and 12-14 points. The outcome was new-onset type 2 diabetes. RESULTS: Multivariable-adjusted hazard ratios from time-varying Cox models were 0.80 (95% confidence interval, 0.70-0.92) per + 2 points in Mediterranean Diet Adherence Screener (linear trend p = .001), and 0.46 (0.25-0.83) for the highest (12-14 points) versus the lowest (< 8) adherence. This inverse association was maintained after additionally adjusting for the randomized arm. Age- and sex-adjusted analysis of a validated plasma metabolomic signature of the Mediterranean Diet Adherence Screener (constituted of 67 metabolites) in a subset of 889 participants also supported these results. CONCLUSIONS: Dietary intervention trials should quantify actual dietary adherence throughout the trial period to enhance the benefits and to assist results interpretation. A rapid dietary assessment tool, yearly repeated as a screener, was able to capture a strong inverse linear relationship between Mediterranean diet and type 2 diabetes. Trial registration ISRCTN35739639.

RESUMO

BACKGROUND: Traditional methods for the diagnosis of leishmaniasis yield poor sensitivity, which limits its effectiveness in lesions with a low parasite burden. METHODS: Retrospective pathologic study of 360 cases of cutaneous leishmaniasis and analysis of the different diagnostic methods used. RESULTS: In 93% of the lesions, histopathology showed a dense and diffuse inflammatory infiltrate, consisting of lymphocytes, histiocytes and plasma cells, which occupied the superficial and mid dermis and variably extended to deep dermis and superficial subcutis (standard pattern). The remaining cases exhibited atypical features, such as perivascular, interstitial or perifollicular inflammatory patterns, folliculitis or panniculitis. Granulomas were identified in 84% of biopsies, most of them as small, poorly formed, non-necrotizing histiocytic aggregates. Amastigotes were visualized by routine histopathologic exam in 36% of biopsies. Immunohistochemistry stained 17 of 26 lesions (65%) negative by conventional stains. PCR provided the correct diagnosis in 218 cases (58% of the series) negative for Leishmania by other techniques. CONCLUSIONS: Biopsies negative for Leishmania by traditional diagnostic methods that show the histopathologic standard pattern, those with atypical features from patients with clinical suspicion of cutaneous leishmaniasis in endemic areas, should be studied by immunohistochemistry and/or PCR for Leishmania in order to reach the definitive diagnosis.

RESUMO

Lagrangian ocean analysis, where virtual parcels of water are tracked through hydrodynamic fields, provides an increasingly popular framework to predict the dispersal of water parcels carrying particles and chemicals. We conduct the first direct test of Lagrangian predictions for emerging contaminants using (1) the latitude, longitude, depth, sampling date, and concentrations of UV filters in raft cultured mussel ( Mytilus galloprovincialis) of the estuary Ria de Arousa, Spain (42.5°N, 8.9°W); (2) a hydrodynamic numerical model at 300 m spatial resolution; and (3) a Lagrangian dispersion scheme to trace polluted water parcels back to pollution sources. The expected dispersal distances (mean ± SD) are 2 ± 1 km and the expected dispersal times (mean ± SD) are 6 ± 2 h. Remarkably, the probability of dispersal of UV filters from potential sources to rafts decreases 5-fold over 5 km. In addition to predicting dispersal pathways and times, this study also provides a framework for quantitative investigations of concentrations of emerging contaminants and source apportionment using turbulent diffusion. In the coastline, the ranges of predicted concentrations of the UV-filters 4-methylbenzylidene-camphor, octocrylene, and benzophenone-4 are 3.2 × 10-4 to 0.023 ng/mL, 2.3 × 10-5 to 0.009 ng/mL, and 5.6 × 10-4 to 0.013 ng/mL, respectively. At the outfalls of urban wastewater treatment plants these respective ranges increase to 8.9 × 10-4 to 0.07 ng/mL, 6.2 × 10-5 to 0.027 ng/mL, and 1.6 × 10-3 to 0.040 ng/mL.

RESUMO

A Reissner-Nordström black hole (BH) is superradiantly unstable against spherical perturbations of a charged scalar field enclosed in a cavity, with a frequency lower than a critical value. We use numerical relativity techniques to follow the development of this unstable system-dubbed a charged BH bomb-into the nonlinear regime, solving the full Einstein-Maxwell-Klein-Gordon equations, in spherical symmetry. We show that (i) the process stops before all the charge is extracted from the BH, and (ii) the system settles down into a hairy BH: a charged horizon in equilibrium with a scalar field condensate, whose phase is oscillating at the (final) critical frequency. For a low scalar field charge q, the final state is approached smoothly and monotonically. For large q, however, the energy extraction overshoots, and an explosive phenomenon, akin to a bosenova, pushes some energy back into the BH. The charge extraction, by contrast, does not reverse.

RESUMO

OBJECTIVES: The aims of this study were to know whether active commuting behaviour differs between fibromyalgia patients and controls, and to test whether active commuting is associated with socioeconomic factors in this population. METHODS: This cross-sectional study included 459 women with fibromyalgia (52.2 years) and 214 female control participants (51.3 years) from Andalusia (southern Spain). Participants reported patterns of active commuting and socioeconomic factors (civil status, accompaniment at home, living with, educational level, and current occupational and professional status). RRESULTS: On the age group <51 years, women with fibromyalgia revealed a significant higher percentage of active commuting for the variable active worker commuters than control group (p<0.05). On the age group ≥51 years, control group displayed a significant higher percentage of active commuting for commuting to local shops, super-market and active commuters variables (all, p<0.05). Women with fibromyalgia who lived alone were more active commuters in comparison to either those living accompanied, or living with both partner and children, only partner and only children (all, p<0.05). CONCLUSIONS: The prevalence of active commuting was similar in women with fibromyalgia and controls aged <51 years. However, fibromyalgia participants aged ≥51 years displayed differences: fibromyalgia women who lived alone were more active commuters than those living accompanied; family demands were inversely associated with commuting patterns. Policies focused on reducing family demands for fibromyalgia patients (i.e. social help on housework, childcare or overprotection) might facilitate the inclusion of daily active behaviours.

RESUMO

The purpose of this study was to examine the differences in illness perception and overall impact on fibromyalgia females from Spain and the Netherlands. A total of 325 fibromyalgia females from Spain (54.3 ± 7.1 years) and the Netherlands (51.8 ± 7.2 years) participated in the study. Illness perception and impact of fibromyalgia were assessed by the Revised Illness Perception Questionnaire and the Fibromyalgia Impact Questionnaire, respectively. Spanish fibromyalgia females perceived more symptoms related to their fibromyalgia (identity) such as nausea, breathlessness, wheezing or fatigue (P < 0.001) and had greater emotional representation (P < 0.01). Dutch fibromyalgia females experienced less timeline (acute/chronic) and consequences (all, P < 0.05), had a better cyclical timeline, personal control, treatment control and illness coherence (all, P < 0.001). Spanish fibromyalgia females reported higher impact of fibromyalgia than Dutch females (61.2 + 14.8 vs. 54.9 + 16.4, respectively; P < 0.001), but the effect size was small (Cohen's d = 0.41) . Impact of fibromyalgia and negative views of fibromyalgia were higher in Spanish fibromyalgia females, whereas Dutch fibromyalgia females presented higher score of positive beliefs about the controllability of the illness. Psychological interventions which help patients to cope with their illness perception might lead to an improvement of the impact of the disease on fibromyalgia females.

RESUMO

The aim of this study was to compare the physical fitness and quality of life related to the health of a sample population of older adult women from Spain and Serbia (60-69 years). A total of 127 female participants of physical fitness programs from Spain (64.33 ± 3.26) and Serbia (63.00 ± 2.88) have participated. Physical fitness (PF), quality of life (QoL) and sociodemographic characteristics were evaluated by Senior Fitness Test, SF-36 Health Survey and socio-demographic questionnaire, respectively. The anthropometric characteristic was measured by corporal measurement. The physical fitness program comprised exercise of strength, agility and aerobic capacity, centering on the Pilates'program and Aerobic. Mean body mass index was 33.6 ± 7.4 kg x m(-2) in the Spanish participants and 25.1 ± 2.6 kg x m(-2) from the Serbian participants (p < 0.001). Similarly, mean waist circumference and body weight of Spanish women was higher than Serbian (p < 0.001; p < 0.05, respectively). Spanish women perceived lower quality of life dimensions than Serbian women, such as physical functioning, social functioning and general health (p < 0.001), general health (p < 0.01) and vitality (p < 0.05). Serbian participants experienced higher physical fitness, such as upper body flexibility (p < 0.05), lower body flexibility, agility and aerobic endurance (p < 0.001). In conclusion, Serbian women were found to have better levels of physical fitness and quality of life than Spanish women. Furthermore, endurance fitness has 73% of explained variance with age, body mass index and fat mass.

RESUMO

We introduce a new time-independent family of analytical coordinate systems for the Kerr spacetime representing rotating black holes. We also propose a (2+1)+1 formalism for the characterization of trumpet geometries. Applying this formalism to our new family of coordinate systems we identify, for the first time, analytical and stationary trumpet slices for general rotating black holes, even for charged black holes in the presence of a cosmological constant. We present results for metric functions in this slicing and analyze the geometry of the rotating trumpet surface.

RESUMO

INTRODUCTION: Pigmented fungiform papillae of the tongue is a benign condition frequent in dark skin patients. It usually appears in the second or third decade of life, and it has been reported as autosomal dominant inheritance pattern. The diagnosis is clinical, but dermoscopy could be helpful: a classical rose petal pattern is observed. The pathogenesis is unknown, and no treatments are effective. CASE REPORT: We report a case of a 15-year-old girl with a pigmented fungiform papillae and a compatible dermatoscopy pattern. CONCLUSIONS: Knowing the existence of this entity and its characteristic dermoscopy, avoids additional invasive medical test. We have to know this entity because it is a variant of normality.


INTRODUCCIÓN: La pigmentación de las papilas fungiformes linguales es una condición benigna y relativamente frecuente en pacientes con piel oscura. Suele aparecer en la segunda o tercera décadas de la vida y se han descrito casos de herencia autosómica dominante. El diagnóstico es clínico, pero la dermatoscopia es de gran ayuda: presenta un patrón clásico en pétalos de rosa. La patogénesis se desconoce y no hay tratamientos efectivos. CASO CLÍNICO: Reportamos el caso de una niña de 15 años con pigmentación de las papilas fungiformes y con patrón dermatoscópico compatible. CONCLUSIONES: Conocer la existencia de esta afección y su característica dermatoscopia evita realizar pruebas invasivas adicionales, ya que se trata una variante de la normalidad.

RESUMO

A(2B) adenosine receptor antagonists may be beneficial in treating diseases like asthma, diabetes, diabetic retinopathy, and certain cancers. This has stimulated research for the development of potent ligands for this subtype, based on quantitative structure-affinity relationships. In this work, a new ensemble machine learning algorithm is proposed for classification and prediction of the ligand-binding affinity of A(2B) adenosine receptor antagonists. This algorithm is based on the training of different classifier models with multiple training sets (composed of the same compounds but represented by diverse features). The k-nearest neighbor, decision trees, neural networks, and support vector machines were used as single classifiers. To select the base classifiers for combining into the ensemble, several diversity measures were employed. The final multiclassifier prediction results were computed from the output obtained by using a combination of selected base classifiers output, by utilizing different mathematical functions including the following: majority vote, maximum and average probability. In this work, 10-fold cross- and external validation were used. The strategy led to the following results: i) the single classifiers, together with previous features selections, resulted in good overall accuracy, ii) a comparison between single classifiers, and their combinations in the multiclassifier model, showed that using our ensemble gave a better performance than the single classifier model, and iii) our multiclassifier model performed better than the most widely used multiclassifier models in the literature. The results and statistical analysis demonstrated the supremacy of our multiclassifier approach for predicting the affinity of A(2B) adenosine receptor antagonists, and it can be used to develop other QSAR models.

RESUMO

In response to the challenges of the 21st century, the European Higher Education Area (EHEA) has been committed to the development of a training model that focuses on the acquisition of cognitive, physical, and social competences, among others, rather than the mere acquisition of knowledge. This approach has gained momentum in recent years, where the learners are the protagonists of their own learning process. This change of approach requires a change in methodology and involves a renewal of the methodological approach in Spanish universities. Service learning (S-L) is an active methodology that is gaining ground across universities due to its experiential, community-based and reflective characteristics. The present study aimed to provide an overview of the impact of S-L by active programs (physical activities, movement games, active tasks, etc.) on the acquisition of professional, linguistic, pedagogical or intercultural competencies, as well as physical wellbeing skills, on English as a foreign language (EFL) teacher education students. Fourteen Spanish EFL university students carried out an S-L active intervention with a migrant group from the Migrant Temporary Stay Centre in the autonomous city of Melilla (Spain). A qualitative study was designed to evaluate the achievement of these competencies. The results show that even though S-L is a challenging methodology, it favours the development of academic, professional, and physical wellbeing competences to succeed in a competitive and changing world, as well as the improvement of the participant students.

RESUMO

BACKGROUND: Although healthcare personnel are considered a high-risk group for SARS-CoV-2 infection due to their exposure, research on the factors associated with their infection is limited. The objective was to identify factors associated with the acquisition of COVID-19 in healthcare personnel. METHODS: a multicenter, cross-sectional study with nested cases and controls was carried out in 23 hospitals in Argentina. A structured survey was used to collect demographic, institutional and behavioral variables from healthcare personnel with positive RT-PCR for SARS-CoV2 (cases) and healthcare personnel with negative test results (controls). Those variables significantly associated with the condition of having had COVID-19 in the bivariate analysis were included in a multivariate analysis. RESULTS: A total of 2088 workers participated in the study, with an incidence of 1.41 cases per 10 000 worker-hours (95%CI 1.35-1.48). Being male, (OR 1.60; 95%CI 1.32-1.95), working in social security, (OR 1.53; 95%CI 1.13-2.07), being nursing staff, (OR 1.46; 95%CI 1.22-1.74), having personal protective equipment, (OR 0.33; 95%CI 0.18-0.62), sharing unprotected common spaces with other workers, (OR 1.98; 95%CI 1. 60-2.44), living with people confirmed or suspected of COVID-19 (OR 1.69; 95%CI 1.37-2.09), sharing infusions or other drinks and/or food with people in the community (OR 1.31; 95%CI 1.02-1.70), feeling distressed (OR 1.85; 95%CI 1.55-2.21) and were independently associated with the risk of acquiring COVID-19. DISCUSSION: This study allowed us to identify different potentially modifiable factors on which action should be taken to reduce the risk of acquiring COVID-19 by the healthcare personnel.


Introducción: Aunque, el personal sanitario es considerado por su exposición un grupo de alto riesgo de infección por SARS-CoV-2, la investigación sobre los factores asociados a infección resulta limitada. El objetivo fue identificar los factores asociados a la adquisición de COVID-19 en el personal sanitario. Materiales y métodos: Estudio multicéntrico, de corte transversal con casos y controles anidados, en 23 hospitales de Argentina. A través de una encuesta estructurada se recolectaron variables demográficas, institucionales y conductuales del personal sanitario con RT-PCR positiva para SARS-CoV-2 (casos) y del personal sanitario con resultados negativos en el test (controles). Aquellas variables asociadas significativamente con la condición de haber padecido COVID-19 en el análisis bivariado fueron incluidas en un análisis multivariado. Resultados: Participaron del estudio 2088 trabajadores, con una incidencia de 1.41 casos c/10 000 horas-trabajador (IC95% 1.35-1.48). Pertenecer al sexo masculino (OR 1.60; IC95% 1.32-1.95), trabajar en la seguridad social (OR 1.53; IC95% 1.13-2.07), ser personal de enfermería (OR 1.46; IC95% 1.22-1.74), contar con elementos de protección personal (OR 0.33; IC95% 0.18-0.62), compartir con otros trabajadores espacios comunes sin protección (OR 1.98; IC95% 1.60-2.44), convivir con personas confirmadas o sospechadas de COVID-19 (OR 1.69; IC95% 1.37-2.09), compartir infusiones u otras bebidas y/o alimentos con personas de la comunidad (OR 1.31; IC95% 1.02-1.70), sentirse angustiado (OR 1.85; IC95% 1.55-2.21) se asociaron independientemente con el riesgo de adquirir COVID-19. Discusión: Este estudio permitió identificar distintos factores potencialmente modificables, sobre los cuales se debería actuar para reducir el riesgo de COVID-19 en el personal sanitario.

RESUMO

Marine debris is a growing problem in recent years due to population growth around the world. The incorrect management of plastic waste causes these bodies reach the seas and oceans, becoming a worldwide problem. Once they reach the seas and oceans, they begin a long period of degradation, moving from a macro state (plastics whose diameter is greater than 0.5 cm) to a micro state (diameter less than 0.5 cm). The microplastics spread throughout the oceans, entering the food chain of marine species and, subsequently, of humans. Therefore, it is important to stop the problem while it remains at the macroscale. In this work, a validation of a recently developed Lagrangian computational model to track the movement of macro plastics in seas and oceans is presented. This validation is performed on a regional scale, in the Ría de Arousa, one of the most important estuaries for mussel cultivation in northwestern Spain. During mussel cultivation in rafts, a type of floating plastic stick are released, the mussel-pegs. The potential of this study is that we can compare the accumulation results of the model with the accumulation data collected on the Galician beaches. In a general framework, the influence of wind on the spatial distribution of the accumulations given by the model was observed. For the monitoring data, similar results were found for the accumulation trends over the entire total period. For the monthly representation, some discrepancies were observed. These differences can be attributed to particular synoptic situations, poor reproduction of the coastline or to the very orientation of the study area with respect to the intertidal dynamics.

RESUMO

Background and objectives: Regular individualised physical exercise (PE) is a habit that not only has consequences for overall health (physical, emotional, social and mental) but can also have positive effects on organisations and institutions, as it helps workers to improve their personal balance and recover from the effort of their working day, showing higher levels of energy, commitment and productivity. The aim of this study was to understand the relationship between the practice of PE and well-being in personal life and at work, as well as job satisfaction, overall health and the assessment of the personal training service provided by final-year students studying for a degree in Physical Activity and Sport Sciences. Methods: This study used a qualitative research methodology. There were 25 employees of the University of Almeria (UAL) (M = 52.16 ± 9.55 years), divided into two focus groups and participating in the physical exercise program "UAL Activa". Results: The following three main themes, based on the results, emerged: (a) social well-being during PE practice, (b) assessment of the personal training service and (c) physical exercise as an emotional benefit at work. Conclusion. The workers' interventions have shown that participating in a personalised PE program led by a personal trainer can improve overall health and mood, with a very positive influence on the working environment.

RESUMO

(1) Background: The main aim of this study was to examine the effect of an intervention of 12 weeks in three groups on anthropometric measurement and heart rate (HR) variables, fitness index, and maximal oxygen consumption (VO2max) in older women. (2) Methods: In total, 166 Serbian adult women, aged 50 to 69 years old, participated in this study, comprising a control group (60 participants, µage = 57.8 + 6.6), Nordic-walking (NW) group (53 participants, µage = 57.5 + 6.8), and recreational-walking (RW) group (53 participants, µage = 57.8 + 6.6) in a physical fitness programme for 12 weeks. (3) Results: Anthropometric measurement variables were measured using a stadiometer and an electronic scale. The data showed differences in walking heart rate (bt/min) (p < 0.001; η2 = 0.088) between control, NW, and RW groups in the pretest analysis. Moreover, there were significant differences in walking heart rate (bt/min) (η2 = 0.155), heart rate at the end of the test (bt/min) (η2 = 0.093), total time of fitness index test (min) (η2 = 0.097), fitness index (η2 = 0.130), and VO2max (η2 = 0.111) (all, p < 0.001) between control, NW, and RW groups in the posttest analysis. (4) Conclusions: NW group training resulted in slightly greater benefits than RW group training. The present study demonstrated that both groups could act as modalities to improve the functionality and quality of life of people during the ageing process, reflected mainly in HR variables; UKK test measurements, and VO2max. It also contributes to the extant research on older women during exercise and opens interesting avenues for future research.

RESUMO

Training for sustainable development is an educational challenge of prime importance. Physical activity and sports in natural environments provide training committed to sustainability and environmental education. The objective of this study was to assess the effects of an undergraduate training program in Physical Activities and Sports in Natural Environments concerned with sustainable development. A total of 113 students from the Autonomous University of Madrid (Spain) who are studying a Bachelor's Degree in Physical Activity and Sports Sciences and a Master's Degree in Teacher Training for Secondary Education and High School (specializing in Physical Education) were involved. Specifically, we aimed to assess the impact of this training program on three dimensions related to Environmental Education (knowledge, behaviors, and attitudes). Its effect was also examined bearing in mind students' sex, age and educational profile (sportive and educational). Mixed-methods were used: for the quantitative approach, data were collected with the Environmental Attitude in Physical Activities in Natural Environments validated scale; for the qualitative approach individual reflective diaries completed by students that attended the program were analyzed. The results show positive effects on the students regarding the three dimensions of Environmental Education, for both the sportive and educational training profiles. The quantitative results do not present significant differences concerning the gender variable, although the qualitative information shows that female students perceived a greater environmental sensitivity during their practices. Regarding the age variable, significant differences are found in the youngest students with an educational profile. To conclude, the study ratifies that the program carried out generated improvements in terms of knowledge, behaviors and attitudes toward the environment and sustainable development. Future research should use larger samples and consider other variables related to education for sustainability.

RESUMO

Black hole (BH)-torus systems are promising candidates for the central engine of γ-ray bursts (GRBs), and also possible outcomes of the collapse of supermassive stars to supermassive black holes (SMBHs). By three-dimensional general relativistic numerical simulations, we show that an m = 1 nonaxisymmetric instability grows for a wide range of self-gravitating tori orbiting BHs. The resulting nonaxisymmetric structure persists for a time scale much longer than the dynamical one, becoming a strong emitter of large amplitude, quasiperiodic gravitational waves. Our results indicate that both, the central engine of GRBs and newly formed SMBHs, can be strong gravitational wave sources observable by forthcoming ground-based and spacecraft detectors.

RESUMO

BACKGROUND: Active aging is aimed at promoting quality of life in older adults. Nevertheless, the relationship between physical role and the practice of physical activity (PA) can be influenced by bodily pain feeling and by a low level of health-related quality of life (HRQoL). Passive and active strategies are susceptible to being modified and constitute an important psychological predictor of adaptation to pain. This cross-sectional study (1) analyzed the differences between inactive/active older adult women in terms of clinical and sociodemographic characteristics, pain coping strategies, and HRQoL; (2) studied the associations between pain coping strategies, the dimensions of the HRQoL questionnaire, and physical role; and (3) determined if passive strategies, bodily pain, physical function, and general health were significant mediators in the link between being inactive/active and physical role. METHODS: Participants of the present cross-sectional study completed measures of clinical and sociodemographic characteristics, HRQoL using the Short-Form Health Survey-36, and active and passive strategies using the Vanderbilt Pain Management Inventory (VPMI). RESULTS: A total of 157 inactive (69.9 ± 7.1 years) and 183 active (68.8 ± 5.3 years) women from rural areas were included in the study. Both groups significantly differed in the majority of the clinical and sociodemographic characteristics measured, pain coping strategies, and HRQoL. Bodily pain, physical function, and general health predicted physical role. Moreover, passive strategies, bodily pain, physical function, and general health mediated the link between inactive/active participants and physical role. CONCLUSIONS: Being physically active or inactive contributes to a better understanding of the link between PA, pain coping strategies, and physical role in older women.

RESUMO

The aim of the present study was to analyze the behavior of players in a standard small-sided game (SSG) according to the role played (offensive (OF), defensive (DF), and wildcard (W)) and its relationship with physical demands (PHYD), technical performance (TP), and internal load (RPE). A total of 24 young highly trained male soccer players (under 16: n = 12; under 19: n = 12) participated. During the SSG, the players alternated the three roles (OF, DF, and W). The duration of each repetition was 4 min with a passive rest of 3 min between them. Furthermore, it emphasized the high demand in all defensive parameters. In addition, DF roles showed higher values in PHYD and RPE, followed by the OF roles, and finally by the W roles. A complementary, positive moderate correlation was found between PHYD and RPE in the U16 dataset (r = 0.45, p < 0.006). Very large positive correlations were also found between PHYD and RPE in the U19 and merged dataset (r = 0.78, p < 0.001 and r = 0.46, p < 0.63, respectively). This information could be useful for coaches in order to structure the roles in SSGs and control training load.
