Leptin in early life: A key factor for the development of the adult metabolic profile

Leptin levels during the perinatal period are important for the development of metabolic systems involved in energy homeostasis. In rodents, there is a postnatal leptin surge, with circulating leptin levels increasing around postnatal day (PND) 5 and peaking between PND 9 and PND 10. At this time circulating leptin acts as an important trophic factor for the development of hypothalamic circuits that control energy homeostasis and food seeking and reward behaviors. Blunting the postnatal leptin surge results in long-term leptin insensitivity and increased susceptibility to diet-induced obesity during adulthood. Pharmacologically increased leptin levels in the postnatal period also have long-term effects on metabolism. Nevertheless, this effect is controversial as postnatal hyperleptinemia is reported to both increase and decrease the predisposition to obesity in adulthood. The different effects reported in the literature could be explained by the different moments at which this hormone was administered, suggesting that modifications of the neonatal leptin surge at specific time points could selectively affect the development of central and peripheral systems that are undergoing modifications at this moment resulting in different metabolic and behavioral outcomes. In addition, maternal nutrition and the hormonal environment during pregnancy and lactation may also modulate the offspring’s response to postnatal modifications in leptin levels. This review highlights the importance of leptin levels during the perinatal period in the development of metabolic systems that control energy homeostasis and how modifications of these levels may induce long-lasting and potentially irreversible effects on metabolis

Psychometric Properties of the Spanish Version of theWork Group Emotional Intelligence Profile Short Version (WEIP-S) in a Sample of Spanish Federated Coaches.

Emotional intelligence has been a topic of great interest to researchers in many different areas as it is associated with mental, psychosomatic, and physical health. In the sports context, it is a significant variable that can play an important role in improving the team’s performance. Although there are numerous tools to assess emotional intelligence, few of them have been validated explicitly in a sports sample, and even fewer have had coaches as a target population. Therefore, this study aimed to validate the Spanish version of the work group emotional intelligence profile short version (WEIP-S) in a sample of Spanish federated coaches. The results confirm that this instrument presents good psychometric properties to measure the emotional intelligence of sports coaches. The original four-factor model (awareness of one’s own emotions, management of one’s own emotions, awareness of others’ emotions, and management of others’ emotions) shows good reliability and convergent validity for all four factors except for the management of one’s own emotions. These findings suggest that it is possible to measure the emotional intelligence of coaches and offer the opportunity to continue investigating the relevance of constructing specific scales to measure this construct in the sports context.post-print363 K

Validation of the Spanish Version of the Work Group Emotional Intelligence Profile Short Version (WEIP-S) in the Sports Context.

Emotional intelligence (EI) is related to better performance in sports. To measure this construct, many tools have been developed and validated in the sports context. However, these tools are based on an individual’s ability to manage their own emotions, but do not consider the emotions of the rest of the team (teammates, coaches, etc.). In this regard, the Workgroup Emotional Intelligence Profile short version (WEIP-S) is a self-reported measure designed to measure the EI of individuals who are part of a team. The aim of this study was to validate the WEIP-S structure to measure EI in the sports context, and to analyze the psychometric properties of this tool in the sample in terms of validity and reliability. A cross-sectional study was conducted among 273 athletes to examine the reliability, factor structure, and evidence of validity (convergent, discriminant, nomological, and concurrent) of the WEIP-S. Confirmatory factor analysis showed that the original four-factor structure is the most appropriate for the sports context. Composite reliability was adequate for all factors except management of one’s own emotions, which also showed poor convergent validity. Evidence of convergent, discriminant, and nomological validity are discussed. This study represents an advance in the use of specific scales to measure EI in the sports context.post-print1021 K

Exercises of Communication for courses related to Business Management and Organizational Behaviour of the Bachelor’s degree in Tourism

Nos basamos en los estudios que caracterizan a los estudiantes de turismo como aprendices activos. Esto significa que son personas que prefieren aprender mediante situaciones y problemas concretos. Por lo tanto, disfrutan más cuando los docentes utilizan estrategias de aprendizaje activo como la metodología de estudios de casos, el aprendizaje basado en problemas (ABP) o las dinámicas de aprendizaje cooperativo versus a las clases magistrales o las exposiciones teóricas. Se proponen dos actividades prácticas para utilizar en la docencia de las asignaturas relacionadas con la dirección de empresas y el comportamiento organizacional del grado de turismo sobre la comunicación grupal.We build on studies that characterize tourism studnets as activist learners. This means that they prefer to learn from concrete problems and situations. Therefore, they enjoy the most when instructors active learning strategies such as the case study method, problem-based learning, or cooperative learning compared to wide theoretical classes and expositions. We propose two practical activities to be used when teaching courses related to tourism business management and organizational behavior of the bachelor’s degree in tourism on the topic of groups’ communication

Postnatal overfeeding during lactation induces endothelial dysfunction and cardiac insulin resistance in adult rats

Early overnutrition is associated with cardiometabolic alterations in adulthood, likely attributed to reduced insulin sensitivity due to its crucial role in the cardiovascular system. This study aimed to assess the long-term effects of early overnutrition on the development of cardiovascular insulin resistance. An experimental childhood obesity model was established using male Sprague Dawley rats. Rats were organized into litters of 12 pups/mother (L12-Controls) or 3 pups/mother (L3-Overfed) at birth. After weaning, animals from L12 and L3 were housed three per cage and provided ad libitum access to food for 6 months. L3 rats exhibited elevated body weight, along with increased visceral, subcutaneous, and perivascular fat accumulation. However, heart weight at sacrifice was reduced in L3 rats. Furthermore, L3 rats displayed elevated serum levels of glucose, leptin, adiponectin, total lipids, and triglycerides compared to control rats. In the myocardium, overfed rats showed decreased IL-10 mRNA levels and alterations in contractility and heart rate in response to insulin. Similarly, aortic tissue exhibited modified gene expression of TNFα, iNOS, and IL-6. Additionally, L3 aortas exhibited endothelial dysfunction in response to acetylcholine, although insulin-induced relaxation remained unchanged compared to controls. At the molecular level, L3 rats displayed reduced Akt phosphorylation in response to insulin, both in myocardial and aortic tissues, whereas MAPK phosphorylation was elevated solely in the myocardium. Overfeeding during lactation in rats induces endothelial dysfunction and cardiac insulin resistance in adulthood, potentially contributing to the cardiovascular alterations observed in this experimental mode

Relación entre inteligencia emocional y ansiedad en un club de fútbol sala de Madrid.

Diversos estudios sugieren que la Inteligencia Emocional en deportistas se relaciona con el rendimiento deportivo y, a su vez, éste se ve perjudicado cuando los deportistas experimentan emociones negativas (e.g, ansiedad) que no son gestionadas adecuadamente. Sin embargo, se necesitan estudios que analicen si esta relación ocurre en todos los niveles deportivos. El objetivo del presente estudio es analizar si existen diferencias en la inteligencia emocional (IE) y los niveles de ansiedad rasgo y estado (A/R y A/E) de jugadores de fútbol sala en función de su nivel deportivo. Para ello, se contó con una muestra de 48 jugadores de fútbol sala de todas las categorías juveniles a los que se les administró los cuestionarios TMMS-24 y STAI. Los resultados obtenidos muestran diferencias significativas en Atención Emocional (AE), A/R y A/E entre los diferentes niveles deportivos. Además, los niveles de A/R se relacionaron con todas las dimensiones de IE, mientras que la A/E únicamente se relacionó con la dimensión de AE.post-print117 K

Collaborative writing of argumentative syntheses by low-performing undergraduate writers: explicit instruction and practice

In writing argumentative syntheses from multiple and contradictory sources, students must contrast and integrate different perspectives on a topic or issue. This complex task of source-based argumentation has been shown to be effective for learning, but it has also been shown to be quite challenging. Because of the challenges, educational interventions have been developed to facilitate performance through such means as explicit instruction of strategies and students’ engagement in collaborative writing. Whereas these interventions have been beneficial for many writers, some students continue to perform poorly. The present study builds on prior research into collaborative writing of source-based argumentative syntheses by focusing on these students who experience difficulty with this academic task. Undergraduate psychology students who had previously underperformed on the argumentative task were organized into 56 pairs to participate in one of four versions of an intervention program, which differed in terms of the extent of support provided. The most complete program included collaboration as well as explicit instruction in argumentative synthesis writing and in the collaboration process. Statistical analyses were carried out with two ANOVAs with planned comparisons as well as two mediation models. Results showed that the pairs of students who received this most complete program significantly improved the quality of their synthesis in two dimensions, argument identification and argument analysis. The quality of their performance exceeded the performance of students in the three other intervention programs. The combination of explicit instruction and practice in pairs had positive effects on argument identification; but, for argument integration, effectiveness could be attributed solely to the explicit instruction component of the intervention. The study contributes to prior research by showing how the components of an intervention can make differential contributions to its effectiveness for a particular group of studentsThe present study was supported by the Ministerio de Ciencia e Innovación State program oriented to the challenges of society (I + D + i) (PID2019-105250RB-I00
