A vueltas de los enfoques en la escuela. ¿Puede la recreación sustituir el aprendizaje?

En la actualidad se vienen manifestando rápidos y continuos cambios que repercuten directamente en la educación de las personas y sus conductas. Es importante realizar consideraciones sobre como incidir en las mismas, y como consecuencia, adaptar el sistema educativo a las necesidades de las personas y la sociedad. Este estudio pretende reflexionar sobre la recreación dentro de este continuo marco de reforma. Para ello hay que entender la recreación en toda su plenitud, no solo en su aspecto lúdico y como método para sustituir determinadas necesidades, sino como medio para favorecer la aparición de las conductas educativas deseadas y el bienestar del individuo. En esta línea se solapan educación física y recreación, al utilizarse la primera para la obtención de los objetivos y fines planteados en la segunda, pretendiendo conseguir un equilibrio en las dimensiones físicas, mentales, emocionales, espirituales y sociales del individuo. Es por ello que en el proceso educacional de enseñanza-aprendizaje del individuo, la recreación no debe ser utilizada para sustituir al aprendizaje, ya que la recreación es una de las muchas formas o metodologías para conseguir determinados aprendizajes

Relação dos indicadores de habilidade e experiência do paraquedismo esportivo militar com o estado psicológico e desempenho em competição de saltadores de elite

Se deben considerar múltiples variables cuando se habla de rendimiento deportivo. Entre ellas, la literatura establece la importancia de la psicología y las técnicas indicadoras de la experiencia adquirida en la disciplina. Este estudio pretende establecer la relación entre determinados constructos que definen el perfil psicológico del deportista con indicadores de habilidad en paracaidismo militar. Para ello, se encuestó a 42 saltadores de 40,86 años (±7,35) pertenecientes al ejército español y a la guardia civil durante la celebración del Campeonato Nacional Militar de paracaidismo que se celebra anualmente, para conocer su nivel de optimismo, resiliencia, bienestar psicológico yburnout. Se concluye que los años de experiencia en paracaidismo y el número de saltos, como indicadores de habilidad, deben ser tomados en cuenta con un mayor nivel de concreción y especificidad, ya que ciertas variables psicológicas pueden aumentar o disminuir dependiendo de ellas. Conviene estudiar cada caso en particular para comprender qué puede ocurrir en el estado del paracaidista y desarrollar estrategias para optimizar el rendimiento deportivoMultiple variables must be considered when talking about sports performance.

Can performance indicators and skydiving experience prognosticate competitive state anxiety in elite paratroopers?

Competition has characteristics that position sport as a fruitful field for the study of human affective processes of interest for psychology, such as anxiety, especially in disciplines such as military parachuting due to its uniqueness. This study aimed to analyse the validity of the Spanish version of the CSAI-2R inventory through a reliable model and to determine the interrelation, both among themselves and with anxiety, of certain specific technical variables related to sports performance in parachuting. The questionnaire was supplied to 42 jumpers in the Spanish National Military Championship. The results indicate that a reliable model has been established, but it is necessary to realise a multivariate relationship between components of competitive anxiety and specific variables of military skydiver's sporting experience in competition. It would be appropriate to reflect on what other psychological and technical variables may influence the sporting performance achieved, because it is a modality that has very particular conditions compared to the rest, not only because of the space, environment and form where and how the activity itself is carried out but also because of the context in which it is framed, as a result of the peculiarities that define the group to which the competitors belong

Influencia de la condición física en el autoconcepto de un conjunto de adolescentes del municipio de Alcantarilla

Un estilo de vida activo es una de las principales conductas potenciales para evitar la aparición de problemas derivados del aspecto físico y de enfermedades que puedan ocasionar alteraciones del autoconcepto de los seres humanos. Por ello es importante prevenir los estilos de vida en edades tempranas, ya que una correcta valoración del nivel de actividad y forma física bajo una perspectiva clínica, puede permitir conocer valores de referencia actualizados de la población objeto de estudio que sirvan para definir objetivos de salud alcanzables. El objeto del presente trabajo es precisamente establecer los valores normativos de condición física de los adolescentes españoles y relacionarlos con el concepto de sí mismo

Effects of a program of vigorous-to-intense physical activity in triglycerides and glucose in 3-to 16-year-old schoolchildren

The aim of this study was to determine if there is a direct association between an intervention program through vigorous-to-intense physical activity and the improvement of certain values of the lipid profile through a fasting analysis of triglycerides and glucose. The sample was composed of 116 schoolchildren between the ages of 3 and 16 (52 boys and 64 girls). A biochemical analysis was used to evaluate the health parameters through a blood draw carried out by the medical staff of the Murcian Health Department. The intervention was carried out 3 times per week during 12 weeks. Through games, rule modification and variations of these, it was favored the use of short repetitions of vigorous and high intensity in races, throws and jumps. The statistical analysis was carried out with the statistical package SPSS 15.0.1 for Windows 8 Pro. It was found an association between the program and the improvement in glucose levels, but not in triglycerides. Furthermore, the improvements were equally significant in males and females of Primary and Secondary Education, but not in Pre-School Education

Design and validation of a psychomotor profile evaluation scale in early childhood education

The lack of evaluation scales of psychomotricity in Early Childhood Education that need in the motor development by evolutionary stage and present a reduced extension of items raises the need to stress on this aspect. The objective of the present study was to design and validate a psychomotor profile evaluation scale in preschool children aged from 3 to 5 years old. The evaluation scale is based on 17 items grouped in 7 dimensions. The content of the scale was validated through the considerations of 6 expert judges, as well as the validity of understanding through 10 preschool teachers. In the same way, a pilot study was carried out, in which the scale of evaluation was applied to 77 participants who were 3, 4 and 5 years old of Early Childhood Education of the "Primary and Secondary Education School Jacinto Benavente" and “Private Center of Education Monteazahar” located in Murcia. The Aiken V values in the content assessment reflected an average score of 0.777 for most items on the three scales, which had to be revised and modified. The students of the school "Jacinto Benavente" showed better ratings than in the "Monteazahar" school. Besides, it was observed that the results among 4-year-old students were the highest versus 3 and 5 years old respectively. As the first phase of the validation process, this evaluation scale must carry on developing until it obtains values that guarantee its purpose

Effects of a 12-week-long program of vigorous-intensity physical activity on the body composition of 6-and 7-year-old children

The purpose was to study the effects of a program of vigorous-intensity physical activity (PA) on the body composition of children. This investigation involved 32 school children from 6 to 7 years old (14 males 6.57 ± 0.51 yr., and 18 females 6.33 ± 0.49 yr.). The variables measured were: body weight, fat-free mass (FFM), fat mass (FM), total body water (TBW), basal metabolic rate (BMR), body mass index (BMI), fat-free mass index (FFMI) and fat mass index (FMI). The body composition analysis was performed using bioelectrical impedance through the body fat monitor Tanita BC 418-MA Segmental. Stadiometer HM - 250P Leicester was also used to obtain the height. The procedure was as follows: pre-test, intervention and post-test. The intervention consisted of 3 days per week of vigorous-intensity physical activity, 15 minutes per day, during 12 weeks. Data analysis was performed through SPSS 23 and significant improvements (Sig<0.05) were obtained in all the variables except for BMI. The physical activity program used in this study may be useful to improve body composition in 6-and 7-year-old children.This work was supported by the Seneca Foundation-Agency for Science and Technology of the Region of Murcia (Spain)

Human IgMhiCD300a+ B cells are circulating marginal zone memory B cells that respond to pneumococcal polysaccharides and their frequency is decreased in people living with HIV

CD300a is differentially expressed among B cell subsets, although its expression on IgM+ B cells is not well known. We have identified a B cell subset expressing CD300a and high levels of IgM (IgMhiCD300a+). Results showed that IgMhiCD300a+ B cells were CD10-CD27+CD25+IgDloCD21hiCD23-CD38loCD1chi, suggesting that they are circulating marginal zone IgM memory B cells. Regarding the immunoglobulin repertoire, IgMhiCD300a+ B cells exhibited a higher mutation rate and usage of the IgH-VDJ genes than the IgM+CD300a- counterpart. Moreover, the shorter CDR3 AA length from IgMhiCD300a+ B cells together with the predicted antigen experience repertoire, indicates that this B cell subset has a memory phenotype. IgM memory B cells are important in T cell-independent responses. Accordingly, we demonstrate that this particular subset secretes higher amounts of IgM after stimulation with pneumococcal polysaccharides or a TLR9 agonist than IgM+CD300a- cells. Finally, the frequency of IgMhiCD300a+ B cells was lower in people living with HIV-1 (PLWH) and it was inversely correlated to the years with HIV infection. Altogether, these data help to identify a memory B cell subset that contributes to T cell-independent responses to pneumococcal infections and may explain the increase in severe pneumococcal infections and the impaired responses to pneumococcal vaccination in PLWH.This work was supported by the following grants to F.B.: Agencia Estatal de Investigación (PID2019-109583RB-I00/AEI/10.13039/501100011033) and Gilead Fellowship Program (GLD15/00303).
