    The results from an experimental analysis of the jump in basketball female and male players are presented. Coordination of seventeen lower limb is analyzed in a high risk movement frequently performed by athletes during jump It is showed that on the sample studied several differences on relative phase are found entailing particularly transverse movement plane of knee. These results show that during some core moments of the jump, gender can influence the lower limb joint coordination. The comparison of relative phase shows a female propensity for moving in less synergy on jump reception. Such findings highlight the need for including on preparation program of athletes a prevention plan that is not necessarily identical on both genders

    A 2-D π–π dimer model system to investigate structure-charge transfer relationships in rubrene

    © The Royal Society of Chemistry 2019Rubrene (5,6,11,12-tetraphenyltetracene) is undoubtedly one of the best performing organic charge transfer mediating materials, with experimentally determined mobilities up to 40 cm2 V−1 s−1. Consequently, there has been increasing interest by means of crystal engineering in trying to generate rubrene-based materials with analogous or even superior conducting properties. Often, experimental measurements are carried out in thin film architectures of these materials, where measured properties can be detrimentally impacted by device manufacture rather than intrinsic charge transfer properties of the material. The latter results in discarding potential good performers. To address these concerns, we report a two-dimensional model system that will allow researchers to predict charge transfer properties of their materials solely requiring the coordinates of the π–π stacking motifs. We envisaged this study to be of significant interest to the increasingly large community of materials scientists devoted to the realisation of improved organic charge mediating materials and particularly to those engaged in exploiting rubrene-based architectures.Peer reviewedFinal Accepted Versio

    Yoga has proven to be an effective exercise to prevent physical and mental illnesses from the early stages of growth, thus improving the health of children and adolescents, and, therefore, the health of adults. This study aimed to find out the degree of judgment and understanding by adolescent students about the practice of yoga, as well as their perspective on the inclusion of yoga in education. An anonymous survey was conducted on 269 participants in different institutes in Andalusia (Spain). The knowledge on the part of the adolescent student students about yoga is very limited. However, the students considered the practice of yoga to be relevant, either as an optional or curricular subject, so that, despite the lack of knowledge of the adolescent students about yoga in general, there was a degree of awareness in favor of this activity in improving education.El yoga ha demostrado ser un ejercicio efectivo para evitar enfermedades físicas y mentales desde las primeras etapas del crecimiento, mejorando, por tanto, la salud de los niños y adolescentes, y, por ende, la salud del adulto. Este estudio tuvo como objetivo conocer el grado de juicio y comprensión por parte de alumnado adolescente sobre la práctica del yoga, así como la perspectiva de estos, sobre la inclusión del yoga en la educación. Se realizó una encuesta anónima a 269 participantes en diferentes institutos de Andalucía (España). El conocimiento por parte de los alumnos adolescentes estudiantes sobre el yoga es muy limitado. Sin embargo, el alumnado consideró relevante la práctica del yoga bien como asignatura optativa o curricular, por lo que, aún el desconocimiento del alumnado adolescente sobre el yoga en general, existió un grado de consciencia en favor de esta actividad en la mejora de la educació
