Convergent validity of two items to differentiate between active and sedentary students
Este estudio examina la validez y fiabilidad de dos ítems de actividad física (AF) incluidos en el CHIP-CE para discriminar entre escolares activos y sedentarios. Se realizó un estudio observacional-transversal, con 1.073 escolares de ambos sexos, de 10-13 años. Mediante los ítems 13 y 28 del CHIP-CE se clasificó a los escolares como activos o sedentarios. La validez convergente fue examinada utilizando como criterio variables de adiposidad, lipídicas, metabólicas, de presión arterial y de fitness.
El coeficiente de correlación de Spearman entre los dos ítems fue de 0,60. Los coeficientes de correlación de Spearman entre la media de los dos items de AF y las variables de salud mostraron valores más altos con el % grasa corporal, la insulina basal, la frecuencia cardiaca de recuperación y el fitness.
La escala de dos ítems extraída del CHIP-CE es un instrumento válido para clasificar a los escolares en activos o sedentarios.This study examined the validity and reliability of two physical activity Child Health and Illness Profile - Child Edition (CHIP-CE) items to differentiate between active and sedentary students. An observational cross-sectional study design was used with 1,073 students from 11 to 13 years old, from 20 schools in the province of Cuenca (Spain). Item 13 and item 28 of the CHIP-CE, a generic childhood quality of life instrument, were evaluated. Convergent validity was examined using adiposity, lipidic, metabolic, blood pressure and cardiorespiratory fitness variables as criteria. The Spearman coefficient of correlation between the two items was 0.60. The Spearman correlation coefficients between the physical activity items and the anthropometric, lipidic, metabolic, blood pressure and cardiorespiratory fitness variables showed higher values with percentage body fat, fasting insulin, recovery heart rate and cardiorespiratory fitness.
Our two-item questionnaire exhibited acceptable validity and high internal consistency for classifying students as either active or sedentary.Este estudio fue financiado por la Consejería de Sanidad de Castilla-La Mancha (beca GC03060-00).

Thermography as a method of acquiring competences in Physiology. Application case for hand blood flow control
5 p.The present work proposes a methodological structure as part of the learning of the circulatory system. For this, the application of thermal stress is used, by immersing the hands in cold water to visualize the reperfusion of the hands. Learning, based on the visualization and analysis of thermographic images, allows the acquisition of specific competences at the university level. In graduate studies such as physiotherapy and nursing, the use of virtual tools and materials that allow the acquisition of skills and technical knowledge is essential for the job performance of future professionals. The application of this methodology is proposed in practical sessions of subjects in the area of knowledge of Physiology, to demonstrate and facilitate the understanding of the circulatory system. This approach is framed within the discipline of virtual laboratories since the virtual materials generated can be used for the acquisition of skills and practical competencies, as well as for the evaluation of competencies in e-learning courses. In this way, by recording a pedagogical video that shows a short practice, 5 minutes long, it is possible to establish the necessary knowledge bases to expand them later. This material is easily implementable in any learning management system.S
Cognitive functioning, physical fitness, and game performance in a sample of adolescent soccer players.
The aim of this study was to analyze the relationships between cognitive functioning, physical fitness, and game performance in a sample of adolescent soccer players. Eighty-five boys from a soccer team in Rincon de la Victoria (Malaga, Spain), aged between 12 and 16 years, participated in the study. The D2 and Global-Local Attention (GLA) tests were used to evaluate selective and divided attention, respectively, and the Coding and Symbol Search tests of the Wechsler Intelligence Scale for Children (WISC-IV) were used for processing speed. To analyze physical fitness, the standing long jump test, speed test, and Course-Navette test of the Alpha-Fitness battery were used. Finally, the Game Performance Assessment Instrument (GPAI) was used to analyze sports performance in three vs. three small-sided games. The analyses showed that cognitive functioning was related to game performance. The results obtained suggest the importance of cognitive functions for performance in this sport
