    Abstract The purpose of this paper was to design and validate a questionnaire about the perceptions of elite studentathletes at university relating to their dual career. In the initial creation of the instrument, constructs were defined and three dimensions were established: academic life, sporting life and sports tutor. After a process of ‘back translation’, experts (n = 8) agreed the construct to ensure content validity, the dimensions and the questionnaire questions. Statistical analysis of the items showed adequate comprehension to confirm content validity of participants (n = 30). In construct validity (n = 73), the results showed correct psychometric quality, internal consistency, reliability and adequacy of the structural model. The instrument had evidence of external validity, since the results were congruent with the main findings of the research. This questionnaire was found to be a valid and reliable assessment instrument, consisting of 84 questions (in Spanish and English language), that enables the perception of elite student-athletes to be known about their dual career whilst at university

    El objetivo de la presente investigación fue diseñar y validar un instrumento de evaluación para conocer la percepción de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual. En la creación inicial del instrumento se definió el constructo y se establecieron tres dimensiones: carrera académica, carrera deportiva y tutor deportivo. En la validez de contenido, tras un proceso de traducción inversa, los expertos (n = 8) valoraron positivamente el constructo, las dimensiones y las preguntas cuestionario. Los resultados estadísticos de los ítems mostraron la adecuada validez de comprensión de los participantes (n = 30). En la validez de constructo (n = 73), las propiedades psicométricas mostraron la adecuada calidad psicométrica, consistencia interna, fiabilidad y bondad de ajuste. El instrumento también contó con evidencias externas de validez, dado que los resultados fueron en la línea de lo que demuestra la literatura. Por ello, este trabajo ofrece un cuestionario válido y fiable de 84 preguntas (en español y en inglés) que permite medir la percepción de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual.Actividad Física y Deport

    An Anti-Human ICAM-1 Antibody Inhibits Rhinovirus-Induced Exacerbations of Lung Inflammation

    Human rhinoviruses (HRV) cause the majority of common colds and acute exacerbations of asthma and chronic obstructive pulmonary disease (COPD). Effective therapies are urgently needed, but no licensed treatments or vaccines currently exist. Of the 100 identified serotypes, ∼90% bind domain 1 of human intercellular adhesion molecule-1 (ICAM-1) as their cellular receptor, making this an attractive target for development of therapies; however, ICAM-1 domain 1 is also required for host defence and regulation of cell trafficking, principally via its major ligand LFA-1. Using a mouse anti-human ICAM-1 antibody (14C11) that specifically binds domain 1 of human ICAM-1, we show that 14C11 administered topically or systemically prevented entry of two major groups of rhinoviruses, HRV16 and HRV14, and reduced cellular inflammation, pro-inflammatory cytokine induction and virus load in vivo. 14C11 also reduced cellular inflammation and Th2 cytokine/chemokine production in a model of major group HRV-induced asthma exacerbation. Interestingly, 14C11 did not prevent cell adhesion via human ICAM-1/LFA-1 interactions in vitro, suggesting the epitope targeted by 14C11 was specific for viral entry. Thus a human ICAM-1 domain-1-specific antibody can prevent major group HRV entry and induction of airway inflammation in vivo

    Implementing the European Sports Leadership Programme: A vehicle to help development graduate workplace competencies

    This research was part of a large intervention study implementing the European Sports Leadership Programme (ESLP). This paper reports the outcomes of the qualitative study that employed focus groups to assess the students’ perceptions of the 15 competencies determined according to the Framework for qualifications of the European Higher Education Area, before and after the ESLP. Focus groups were carried out at each of the five universities. The ESLP involved university students working as a sports leader for 24 months with the aim to engage more students in university sport, whilst they took part in a graduate employability programme. Each university recruited five sports leaders in their second year at university, to deliver 10 new sport and recreational activities targeting the wider inactive or semi-active student population. Findings highlighted that Organization and planning, Oral and written communication, Development of planning and decision making, and Teamworking, followed closely by Emotional control and Adapting to new situations, were the most commonly reported competencies. They affirmed that this programme had helped to develop these competencies. Use of information, communication and technology, Communication in a foreign language, Research and Emotional control were the most common competencies that students stated they needed to improve further. This research found that implementing the ESLP helped to develop students’ perceptions of their workplace and career competencies. The ESLP is therefore, recommended as one approach to helping universities to develop student’s workplace and career competencies

    Effects of a sport leadership programme on the perceptions of university students about their leadership competencies (Efectos de un programa de liderazgo deportivo sobre las percepciones de alumnado universitario)

    The main purpose of this study was to evaluate the effects of a sport leadership programme (ESLP) on variables related to the leaders’ perception regarding instrumental, personal, and systemic skills in university students. In doing so, the second purpose was to analyse the trans-cultural validity of the Cuestionario de Evaluación de Competencias Transversales de Grado (CECTGRA). Participated 61 students as leaders, 25 mentors and 25 employers, from five European countries. The design was pre-test-post-test, following a longitudinal approach of 24 months to evaluate the effects of the ESLP on variables related to the leader’s perception. An adaptation of the CECTGRA was administered. The questionnaire was valid and reliable to know the effects of the ESLP on the students’ perceptions. However, the sports leaders did not improve their perceptions of competence regarding development, mastery and relevance after the application of the programme. From the finding of this study it is recommended to improve the programme based on the leadership competencies to develop, the teaching-learning methodologies to follow, the activities to implement, and the roles to determine

Una adaptación del CECTGRA fue contestado en las evaluaciones pre-test-post-test. El cuestionario fue válido y fiable para saber los efectos del ESLP sobre las percepciones de los estudiantes. Sin embargo, los líderes deportivos no mejoraron sus percepciones de competencia respecto a desarrollo, dominio y relevancia tras la aplicación del programa. A partir de estos resultados, se recomienda mejorar el programa a partir de las competencias de liderazgo a desarrollar, las metodologías de enseñanza-aprendizaje a seguir, las actividades a implementar y los roles a determinarActividad Física y Deport
