Análisis bifactorial de la Escala de Autoestima de Rosenberg y relación entre actividad física y autoestima en adolescentes
Self-esteem is a construct of great importance in adolescence that favors the health and psychological well-being of schoolchildren. In this paper, the two-dimensionality of the Rosenberg Self-Esteem Scale (RAS) is analyzed through confirmatory factor analysis, as well as the relationships between the practice of physical activity (PA), Global self-esteem, and the positive and negative dimensions of self-esteem. It was carried out in a sample of 429 students in the high school of the city of Seville (Andalusia). The instruments used were the Physical Activity Questionnaire in adolescents (PaqA, Martínez-Gómez et al., 2009) and the Rosenberg Self-Esteem Scale (EAR, 1965) version of Atienza et al. (2000). The results obtained allow us to accept the two-dimensionality of the scale, as well as good levels of global self-esteem and a tendency to better self-esteem in active adolescents. The practice of PA is associated with the Positive Self-esteem dimension, but not with Negative Self-esteem or Global Self-esteem.La autoestima es un constructo de gran importancia en la adolescencia que favorece la salud y el bienestar psicológico de los escolares. En este trabajo se analiza la bidimensionalidad de la Escala de Autoestima de Rosenberg (EAR) mediante análisis factorial confirmatorio, así como las relaciones existentes entre la práctica de actividad física, Autoestima Global y las dimensión positiva y negativa de la autoestima. Se llevó a cabo en una muestra de 429 estudiantes de Educación Secundaria Obligatoria y Bachillerato de la ciudad de Sevilla (Andalucía). Los instrumentos utilizados fueron Cuestionario de Actividad Física en adolescentes (PaqA de Martínez-Gómez et al., 2009) y Escala de Autoestima de Rosenberg (EAR, 1965) versión de Atienza et al. (2000). Los resultados obtenidos permiten aceptar la bidimensionalidad de la escala, así mismo se constató buenos niveles de autoestima global y una tendencia a una mejor autoestima en los adolescentes activos. La práctica de actividad física se asocia con la dimensión Autoestima Positiva, pero no con la Autoestima Negativa y la Autoestima Global

Analysis of external load and internal load in AirBadminton: A new healthy and recreational sports modality
The aim of this study was to compare internal load and external load between AirBadminton and traditional indoor badminton. The research was conducted with 8 badminton players from the Alicante Technification Centre, including both men and women. The study was carried out based on the recommendations and guidelines of the International Badminton Federation. The procedure included competitions in both 1vs1 and 2vs2 formats, first on sand and then on hard court. Various variables related to players' internal and external load were analysed, using devices such as WIMU PRO for external load and Polar H7 transmitters for internal load. Data analysis was performed using statistical tests such as T-Student and Wilcoxon. Results showed significant differences between indoor badminton and AirBadminton in terms of internal and external load. In the 1vs1 format, indoor badminton was found to be more demanding, with higher intensity efforts, greater distance covered, and higher heart rate compared to AirBadminton. Similar results were observed in the 2vs2 format, confirming that indoor badminton involves greater effort. AirBadminton may be a healthier and more accessible alternative, suitable for different age groups, as it is less explosive and lighter in terms of internal and external load. Future research should focus on technical, tactical, and full-match duration aspects of this new modality
Impact of socioeconomic level on the physical condition of schools: A motor gap
The objective of this study was to analyse the physical condition of students in the third cycle of Primary Education from various educational centres in the Province of Alicante, in relation to their socioeconomic level. The study sample was made up of a total of 240 students from the third cycle of Primary Education, specifically 136 boys and 104 girls, from various schools located in three different geographical environments in the province of Alicante (urban, rural, coastal). A correlational and descriptive study was carried out. To measure the socioeconomic level of the students, families completed the Social Class Questionnaire; Regarding the anthropometric and motor condition of the students, body composition, musculoskeletal capacity, aerobic capacity and motor capacity were evaluated, for which the ALPHA-Fitness battery was used. In addition, to measure the students' adherence to the Mediterranean diet and extracurricular sports activity, the students filled out the KIDMED and PAQ-C questionnaires (Physical Activity Questionnaire for Children) respectively. The results showed that the students in the study with a higher socioeconomic level have a better physical condition in terms of body composition, musculoskeletal capacity, aerobic capacity and motor capacity. Therefore, it is necessary to implement programs and activities that encourage the practice of physical activity and the acquisition of healthy habits, especially in the most disadvantaged areas
El uso del entorno local en la formación científica de los futuros docentes
Partiendo de las últimas tendencias en didáctica de las ciencias, este trabajo subraya la importancia del uso del entorno local en la contextualización de la enseñanza de las ciencias. No solo se considera esta perspectiva didáctica como punto de partida del proceso de aprendizaje, sino también como ámbito de aplicación de los conocimientos adquiridos. La formación de los futuros docentes requiere que estos sean capaces de conocer e identificar aquellos elementos significativos del entorno local (naturales, sociales, culturales), como base para desarrollar propuestas didácticas contextualizadas en el mismo. Se exponen algunas de las acciones que se desarrollan en este sentido con los maestros en formación inicial
Notational Comparison Analysis of Outdoor Badminton Men’s Single and Double Matches
The objectives of this study were to determine the results of the analysis of single and double outdoor badminton men’s matches and to determine the relationship between technical and tactical aspects in a study organized by the BWF (Badminton Word Federation), on a sand surface. Twenty men’s singles matches were recorded using video cameras and analysed with a Dartfish video analysis software package. Along with this, percentages of use of technical elements were analysed by comparing the different modalities. For the single format Lob, Clear, Drop, Smash, Drive were used, different from the double format that used Lob, Clear, Drop, Smash, Drive. The study confirmed the applicability of computerized notation analysis to determine the characteristics of Outdoor Badminton on sand
Study on the essential amino acid’s supplements with absorption patterns in the improvement of the performance for sportspeople: GFS AMINO
Sports-people’s performance at their sport can vary due to the development of their athletic activity when competing. In addition to this, the scientific community have recently increased their interest for the study of essential amino acid’s supplements (EA). The purpose of the present study is to examine the effect of the ingestion of an amino acid’s supplement with absorption patterns and its relationship with the performance of 32 sportsmen in a maximum stress test of their VO2max. For this study we used a double-blind design. Thirty-two experienced sportsmen, (aged 34 ± 6.5 and; height 178.5 ± 4.5 cm; weight 72.6 ± 8.6 kg), were evaluated during their performance. All of them followed an ingestion protocol of an amino acid supplement with absorption patterns (16.6gr) of GFS AMINOS dissolved in 140ml of water, 20 minutes before starting the test and a later execution consisting in an increasing-stress test, until they stopped voluntarily. At the end of the test we carried out a measuring of their Body Mass Index (BMI), a blood-lactate, a lower body strength test and a cognitive test. The results of this study showed significant differences (P < 0.05) in the performance over time and duration in the stress test, together with a lower loss of cognitive attention and a decreasing of the fat percentage. In sum, this essential amino acid supplement with absorption patterns GFS AMINOS can improve sports-people’s performance and accelerate the use of body fat
