Influence of physical fitness components on personality factors and risk perception of children and adolescents: a cross-sectional study.

OBJECTIVES: To examine the associations of cardiorespiratory fitness (VO2 max) and muscular strength with indicators related to the risk scale, such as perceived competence, sensation seeking, competitiveness, risk taking and risk perception in sports. DESIGN: Cross-sectional study. SETTING: High schools from the Region of Murcia (Spain). PARTICIPANTS: Three-hundred-and-seventeen adolescents participated (mean age: 13.69±1.2 years old). PRIMARY AND SECONDARY OUTCOME MEASURES: Body mass, body height, Course-Navette test, upper limb strength and psychoeducational factors that determine the propensity towards sports accidents in school children, the Sports Accident Propensity Scale were evaluated. It was performance t-test for independent samples, stepwise multiple linear regression models and a multiple mediation analysis. RESULTS: The analysis showed significant differences with respect to sex in height, VO2 max, handgrip strength and in all factors of the questionnaire (p=0.02-<0.01). Adolescents who presented greater VO2 max, strength in the handgrip test and age showed a higher score in factors 1 and 3. Higher scores in factor 2 were associated with better VO2 max and strength in handgrip test. Youngers and better values of strength in the handgrip showed higher score in factors 4 and 5. The mediation analysis with two mediating variables (handgrip strength and VO2 max) showed a significant indirect effect. When handgrip strength and VO2 max were included in the equations, the association between sex and each factor ceased to be significant. CONCLUSION: This study highlights the potential benefits of muscular strength (handgrip) and VO2 max in the perceived risk scale, and the variable of age on this. TRIAL REGISTRATION NUMBER: Clinical trial: NCT05544370 (pre-results).

The impact of videogames on the mood of amateur youth players during consecutive games.

Introduction: Esports have experienced tremendous growth in recent years. In the scientific field, previous research has shown the determining role of psychology in competitive performance, but little is known about the factors that may be more determinant. In addition, in the amateur field, where fun and enjoyment are the most important factors, it has been observed that players can see their psychological state altered due to different factors, but it is not known if the outcome of the game (win or lose) can be influential. For this reason, the aim of the present investigation was to analyze changes in players' mood between three consecutive games as a function of the outcome of each game. Methods: A total of 14 amateur players participated in the research, all of them with previous experience and being regular League of Legends players. The participants completed the POMS questionnaire before the start of each game and the outcome of each game was recorded at the end. Results: The results showed that no significant pre-game differences were found in any of the games, regardless of winning or losing. Significant differences were found in the pre-game mood between the first and second game, according to the outcome of the first game, and between the second and third game, according to the outcome of the second game. Between the first and second games, there was a significant increase in depression (p = 0.038) and anger (p = 0.003) when the first game was lost; and between the second and third games, there was a decrease in tension (p = 0.003) and anger (p = 0.022) when the second game was won. In addition, it should be noted that fatigue increased significantly after each game, regardless of the outcome, and with respect to the change in mood, this was more noticeable when the first game was lost and the second was won, as significant changes were observed in tension (p = 0.028), depression (p = 0.030) and anger (p = 0.006). Conclusion: Pre-match mood does not influence post-match performance, but mood changes do occur between successive matches depending on the outcome of the match.

Assessment of the Corrosion of Steel Embedded in an Alkali-Activated Hybrid Concrete Exposed to Chlorides.

Hybrid alkali-activated cements (HAACs), also known as cements with high percentages of alkali-activated supplementary materials, are alternative cements that combine the advantages of ordinary Portland cement (OPC) and alkali-activated systems. These cements are composed of a minimum of 70% precursor material and a maximum of 30% OPC mixed with an alkaline activator. This article evaluates the corrosion performance of reinforced HAAC concrete based on fly ash (FA) under exposure to chlorides (FA/OPC, 80/20). Its performance is compared with that of a binary alkali-activated cement (AAC) based on FA and granulated blast furnace slag (GBFS) (FA/GBFS, 80/20). The tests performed on the concrete matrix correspond to the compressive strength and permeability to chloride ions. Using accelerated corrosion techniques (impressed voltage) and electrochemical tests after immersion in 3.5% NaCl, the progress of the corrosive process in the reinforcing steel is evaluated. The FA/OPC exhibit a better corrosion performance than the FA/GBFS concrete. At the end of the exposure to chlorides, the FA/OPC hybrid concrete presents the best performance, with a 49% lower corrosion rate than that of the FA/GBFS. Note that according to the polarization curves, the values of the proportionality constant B in the alkaline-activated concretes differ from the values recommended for concrete based on OPC.

Gender Stereotypes among Teachers and Trainers Working with Adolescents.

Previous scientific literature has not determined the influence exerted by trainers and teachers of adolescents on the development of gender stereotypes in sport. For this reason, the aims of the present research were to establish differences in gender stereotypes in sport among teachers and trainers as a function of profession and sex and to analyze the influence of age and years of experience of male and female trainers and teachers on the gender stereotypes in sport. For this purpose, 127 teachers and trainers completed the questionnaire "gender beliefs and stereotypes towards physical activity and sport". The results showed a significantly higher score of the teachers in "beliefs about physical activity and gender" (p = 0.048) and of the trainers in "physical education classes and gender" (p = 0.006). Concerning sex, women showed higher scores in "sport and gender" (p = 0.005), and men in "beliefs about physical activity and gender" (p = 0.045). Regarding covariates, age showed significant differences in "sport and gender" (p = 0.029), with female teachers showing higher values with respect to female trainers and male teachers, while years of experience showed differences in "beliefs about sport and gender" (p = 0.044), with male teachers showing higher values than male trainers and female teachers.

A amostra foi composta por 965 adolescentes e 1599 pais da Região de Múrcia. Os resultados mostraram diferenças na prática desportiva dos adolescentes ao considerar o nível educacional das mães, a atividade física realizada pelos pais para os homens, a frequência da prática das mães para as mulheres e os estereótipos de gênero das mães. Como conclusões, é de notar que os estereótipos de gênero e o nível de educação dos pais influenciaram a prática do desporto pelos adolescentes.

Abstract The importance of parents in the physical activity of their children during adolescence has been previously established, but few studies have determined which are the most important variables. This study analyzes the influence of gender stereotypes, educational level, and the level of parents' sports practice on their children's practice. The sample included 965 adolescents and 1,599 parents from the Region of Murcia. The results showed differences in the sports practice of the adolescents when considering the educational level of their mothers, the physical activity carried out by the fathers on male children, the frequency of practice of the mothers for female children and gender stereotypes of the mothers. It found that gender stereotypes and parents' educational level influenced adolescents' sports practice.

Gender differences in quality of life in adults with long-standing type 1 diabetes mellitus.

BACKGROUND: To assess gender differences in Quality of life (QoL) and in sociodemographic, clinical and psychological factors associated with impaired QoL in adults with long-standing type 1 diabetes mellitus (DM1). METHODS: Cross-sectional evaluation in a random cohort of DM1 adult patients from a tertiary care hospital. QoL was evaluated using translated and validated self-administered Diabetes QoL questionnaire (Es-DQoL), and results transformed into a 0-100 scale. Psychological assessment included a planned psychological interview and self-reported questionnaires (Beck Depression Inventory II, State-Trait Anxiety Inventory Form Y, Fear of hypoglycaemia Scale, Medical Outcomes Study Social Support Survey). RESULTS: A total of 312 patients (51.6% male; 38.2 ± 12.7 years; HbA1c 7.5 ± 1.1% (58.5 ± 14.2 mmol/mol); 20.4 ± 12.0 years of DM1) were included in the analysis. Male and female subgroups showed similar sociodemographic and diabetes-related features and comparable social support. Among female patients, higher frequency of depression [31.7% (IC95% 26.2-40.8) vs. 14.9% (IC95% 10.1-20.8), p < 0.05] and anxiety [23.2% (IC95% 19.3-33.14) vs. 13.0% (IC95% 8.1-18.4), p < 0.05] and severity of depressive and anxious symptoms were also found. Compared to male patients, female patients showed lower QoL [75 (IC95% 73.6-77.5) vs. 80 (IC95% 75.7-83.1), p < 0.05] and scored significantly worse in subscale Diabetes-related worries [69 (IC95% 50.0-81.0) vs. 75 (IC95% 72.9-79.0), p < 0.05]. Fear of hypoglycemia and severity of depressive and anxious symptoms were factors independently associated to lower QoL in men and women while high frequency of glycemic excursions was a female-specific predictive one. CONCLUSIONS: Adult women with long-standing DM1 showed lower QoL probably related to higher frequency and severity of psychopathological syndromes. Depressive and anxious symptoms and, among women, exposure to glycemic excursions were identified as modifiable, QoL-related variables. Educational, technological and psychological interventions are needed in order to improve QoL in DM1 patients.

Interacciones potenciales entre productos fitoterápicos con laxantes antracénicos y otros fármacos. Detección en farmacias comunitarias de Sevilla / Potential interactions between phytotherapycs anthracenics laxatives products and other drugs. Detection in community pharmacies of Seville

Introducción: Los productos fitoterápicos más dispensados en España son los laxantes. Los laxantes antracénicos como el acíbar de aloe (Aloe spp.) o la corteza de cáscara sagrada (Rhamnus purshianus), entre otros, podrían estar implicados en interacciones farmacológicas debido al riesgo de hipopotasemia que produce su uso continuado. Objetivos: Realizar un análisis de la situación de dispensación de estos laxantes y detectar potenciales interacciones con otros fármacos en farmacias de la Provincia de Sevilla. Material/Métodos: Estudio descriptivo, observacional, realizado desde 14 farmacias comunitarias, mediante aplicación de un cuestionario acerca del uso de plantas medicinales. Se identificaron las interacciones potenciales descritas en las monografías EMA y ESCOP, y se analizaron los factores de riesgo para las mismas (edad avanzada, polimedicación y frecuencia de consumo). Resultados: La muestra fue constituida por 252 pacientes. El 24,6% (n = 62) consumían laxantes antracénicos, más del 50% de forma diaria. El porcentaje de asociación con otros fármacos fue del 70%. Se han identificado potenciales interacciones en el 40% (n = 26) de los pacientes, basadas en la asociación del laxante con fármacos diuréticos, con fármacos que podrían prolongar el intervalo QT, o con ambos a la vez. En todos ellos se detectó la existencia de uno o varios Factores de Riesgo para la Interacción (FRI). Conclusiones: Los resultados obtenidos reflejan la necesidad de formación actualizada por parte de los farmacéuticos comunitarios sobre los beneficios y riesgos de estos fitomedicamentos. Su dispensación protocolizada favorecería la identificación de posibles interacciones farmacológicas y su uso seguro y racional

Background: The most dispensed phytotherapeutic products in Spain are laxatives. An-thracenic laxatives such as aloe vera (Aloe spp.) or cascara sagrada (Rhamnus purshianus) could be involved in drug interactions due to the risk of hypokalemia caused by their continued use. Objectives: To carry out an analysis of the dispensing situation of these laxatives and detect potential interactions in pharmacies of the Province of Seville. Material / Methods: A descriptive, observational study made from 14 Pharmacy Offices, through the application of a questionnaire about the use of medicinal herbs. The potential interactions described in the EMA and ESCOP monographs were identified, and the risk factors for them (advanced age, polymedication and frequency of use) were analyzed. Results: The sample was constituted by 252 patients. 24.6% (n = 62) consumed anthracene laxatives, more than 50% daily. The percentage of association with other drugs was 70%. Potential interactions have been identified in 40% (n = 26) of the patients, based on the association of the laxative with diuretic drugs, with drugs that could prolong the QT interval, or with both at the same time. In all of them, the existence of one or several Risk Factors for Interaction (FRI) was detected. Conclusions: The results obtained show the need for updated training by community pharmacists on the benefits and risks of these phytoterapics products. Its protocolized dispensation would favor the identification of possible pharmacological interactions and their safe and rational use

Emotional abilities and HbA1c levels in patients with type 1 diabetes.

In recent years a growing body of research is focused on the relationships between emotions and health. When it comes to diabetes, findings suggest that distress might play a key role in the acquisition and maintenance of health habits associated with diabetic management. This report describes two studies examining the roles of emotional abilities in diabetic management from two different conceptual points of view using two culturally different samples. In study 1, we examined the relationship between emotional intelligence and HbA1c levels in a sample of eighty-five patients with type 1 diabetes mellitus (DM1) in Israel. In study 2, we examined the relationship between specific emotional regulation strategies and HbA1c in sixty-seven adolescents with DM1, while examining the mediating role of distress in this association. The results showed a negative association between emotional intelligence and HbA1c levels, even after controlling for potential intervening factors. We found that the relationship between difficulties in emotion regulation and HbA1c seemed to be mediated by diabetes-related distress. These findings may aid in the design of psychological models for future research as well as interventions aimed at improving emotional abilities in people with DM1.
