Maximal oxygen consumption in Mexican university studenst: Correlation between five predictive tests

El objetivo de este estudio fue determinar si existen diferencias en los valores de VO2max indirecto obtenido con cinco pruebas físicas: UTMM, VAM-EVAL, Ida- Vuelta, 1000 m y Ramsbottom. Los sujetos fueron hombres mexicanos en edad universitaria sin entrenamiento previo y sin experiencia en deportes, con los siguientes parámetros: edad 19,33 ± 1,09 años (media ± 1 desviación estándar), peso 68,47 ± 9,93 kg, estatura 1,71 ± 0,06 m e IMC 23,62 ± 2,82. El VO2max indirecto (ml/kg/min, media ± 1 error estándar) por prueba fue de: 44,26 ± 3,74 para UMTT, 44,14 ± 3,01 para VAM-EVAL, 42,78 ± 2,80 para Ida y vuelta, 44,92 ± 2,33 para 1000 m y 42,67 ± 2,96 para Ramsbotton. No se encontraron diferencias significativas entre el VO2max indirecto obtenido por los sujetos de estudio en las cinco pruebas. Concluimos que las cinco pruebas son equivalentes y pueden ser usadas indistintamente para evaluar el VO2max indirectoThe objetive of this study was determining if there are differences in the measurement of indirect VO2max among five different physical tests: UMTT, VAMEVAL, 20 MST, 1000 m and Ramsbottom. The subjects were Mexican college-age men without previous training and without sport experience with the following parameters: years 19,33±1,09 (mean ± 1 standard deviation), weight 68,47 ± 9,93 kg, height 1,71 ± 0,06 m and body mass index 23,62 ± 2,82. VO2max indirect (ml/kg/min, average ± 1 standard error) by test were: 44,26 ± 3,74 for UMTT, 44,14 ± 3,01 for VAM-EVAL, 42,78 ± 2,80 for 20 MST, 44,92 ± 2,33 for 1000 m and 42,67 ± 2,96 for Ramsbotton. We do not detect significant differences between the indirect VO2max obtained in the five tests. We concluded that the five tests are equivalent and can be used interchangeably to assess the indirect VO2ma

Watching the games: Critical media literacy and students’ abilities to identify and critique the politics of sports

Sport can be the source of fitter, healthier and better lifestyles. However, sport can also be a vehicle for the reproduction of problematic notions of gender, race, nationality, industry, et cetera. If people who consume and participate in sport are unequipped to identify and question these issues, they will continue reproducing these conceptions uncritically. As a proponent of Critical Media Literacy (CML), through this dissertation I encourage educators to teach students the skills and knowledge to recognize and critically assess these and other problematic discourses in sports media. In this dissertation, I set out to discover if adolescents possess these skills and knowledge. Two main questions drive this research: First, what type of knowledge do the participants have about the socio-cultural, political and economic implications of sport in our societies? And second, can the participants identify socio-political issues (e.g. gender, race, nationality, political economy) in sports media texts as they consume them? To answer these questions, I first attempted a study with youth and later I recruited 20 first year university students to participate in a 90 minute session where I showed them three sports clips and asked them to complete a short qualitative questionnaire and partake in a focus group discussion. Using Qualitative Content Analysis (QCA), I examined both the questionnaires and the transcripts from the discussions leading to a critical analysis. I found that the participants had a limited knowledge of the general and critical media issues we discussed. Though the students demonstrated some understanding of the way the sports media operates, they consistently drew from stereotypes and common sense tropes when analyzing issues of race, nationality and gender in sports. I also found that students were generally unable to identify and/or critique problematic representations present in the videos. There were only 5.6% of instances where the participants questioned these problems in the clips. Most of the time (86.23%) the participants were either unaware of the issues or saw them as normal and saw no need to resist or critique. These findings support the idea that students would benefit from receiving a critical media literacy education that teaches them to identify and question hegemonic discourses in sports media

Anàlisi de les diferències quantitatives de la tècnica entre els alumnes d’una escola d’ensenyament de la natació

L’estudi es va centrar en l’avaluació quantitativa de la tècnica natatòria dels alumnes d’una escola de natació on es va portar a terme un programa d’aprenentatge per nivells d’execució, els alumnes de la qual tenien una mitjana d’edat de 7 anys. Van ser recollides diferents variables tècniques quantitatives i antropomètriques, i es va diferenciar entre gènere i grup, segons el nivell d’execució. Es va fer una anàlisi quantitativa de les variables tècniques dependents: velocitat (V), freqüència de cicle (F), i longitud de cicle (L) dels diferents estils: crol (C), esquena(E) i batuda de crol amb planxa (bC) junt amb característiques antropomètriques com el pes, la talla i l’envergadura, segons el gènere i l’edat. Els resultats mostren que en aquestes edats no s’obtenen diferències significatives entre gèneres ni entre nivells d’execució en moltes de les variables. No es va observar relació entre els resultats quantitatius obtinguts i la distribució qualitativa, segons el nivell d’execució, de cada un dels nedadors

Subsidios y Estrategias de Producción Campesina : el caso de Casas Blancas, México

El análisis del metabolismo social brinda los elementos para comprender las interacciones que mantiene la sociedad con la naturaleza. Bajo esta perspectiva este artículo analiza a diferentes las relaciones sociales y económicas de tres sistemas de manejo de recursos naturales (SMRN) en una comunidad rural de México. Se construyó una tipología de sistemas basada en los componentes productivos y las instituciones locales asociadas a estos. Cada sistema se analizó considerando tres tipos de flujos: i) flujos monetarios provenientes de los subsidios; ii) flujos materiales de la producción agrícola y pecuaria y iii) flujos de mano de obra. Se hizo una caracterización a tres escalas: componente productivo, sistema y comunidad. Los resultados obtenidos muestran que existe una interacción negativa entre los subsidios y la diversificación productiva y una interacción positiva entre el número de componentes y la demanda de mano de obra. Se asocian los subsidios de plantaciones comerciales y las formas de organización social con la disminución de superficie agrícola y aumento de la superficie forestal. Estos resultados permiten conocer los factores internos y externos del sistema que afectan las estrategias campesinas de manejo de recursos naturales vinculadas con la autosuficiencia alimentaria.Social metabolism analysis gives the conceptual basis to understand interactions between society and nature. Beyond this perspective and the systems theory, this article analyzes at different scales social and economic relations of three natural resources management systems in a rural community from Mexico. A system typology was constructed based on the productive components and local institutions. Each system was studied considering three types of fluxes: i) monetary fluxes from subsidies; ii) material fluxes from agricultural and livestock production and iii) labour fluxes. A characterization of these fluxes was made at three scales: i) productive component (maize, livestock and forest); ii) parcels (system) and iii) community. The results showed that there is a negative interaction between subsidies and productive diversification and a positive interaction between number of components and labour demand. Subsidies for commercial forest plantations and social organization are associated with the diminution of agricultural area and an increase of forest cultivated surface. These results had shown some of the internal and external factors that affect peasant strategies of natural resources management and its implications with self sufficiency

Comparative Study of Optimal Multivariable LQR and MPC Controllers for Unmanned Combat Air Systems in Trajectory Tracking

[EN] Guidance, navigation, and control system design is, undoubtedly, one of the most relevant issues in any type of unmanned aerial vehicle, especially in the case of military missions. This task needs to be performed in the most efficient way possible, which involves trying to satisfy a set of requirements that are sometimes in opposition. The purpose of this article was to compare two different control strategies in conjunction with a path-planning and guidance system with the objective of completing military missions in the most satisfactory way. For this purpose, a novel dynamic trajectory-planning algorithm is employed, which can obtain an appropriate trajectory by analyzing the environment as a discrete 3D adaptive mesh and performs a softening process a posteriori. Moreover, two multivariable control techniques are proposed, i.e., the linear quadratic regulator and the model predictive control, which were designed to offer optimal responses in terms of stability and robustness.This work was partially funded by project RTI2018-096904-B-I00 from the Spanish Ministry of Economy and by project AICO/2019/055 from Generalitat Valenciana.Ortiz, A.; Garcia-Nieto, S.; Simarro Fernández, R.

Referral pattern and co-management of keratoconus patients in primary eye care: A survey of three European countries

Producción CientíficaPurpose: To explore current primary care practices in keratoconus management in Portugal and compare with previous reported results in two European countries (the UK and Spain), with a special focus on interdisciplinary collaboration and referral practice patterns. Methods: An online survey adapted to European professional practice was distributed (via newsletters) by the Portuguese Optometrist Association to explore keratoconus patient management and referral practice patterns among Portuguese practitioners. Results: Responses of 119 optometrists were compared with previous reported of 464 eye-care practitioners (126 in the UK and 338 in Spain). Most respondents (79% in Portugal, 71% in the UK and 76% in Spain; p = 0.31) had < 5 new keratoconus patients each year. No accepted referral criterion was found (p < 0.01) because small number of the respondents (14%) in Portugal referred out at initial diagnosis (50% in the UK and Spain); 32% referred out when progression was detected (17% in the UK and 30% in Spain); and a minority (10% in Portugal, 9% in the UK, and 6% in Spain) referred out when visual acuity was affected. A majority of respondents (83%) in Portugal reported no co-management with ophthalmologists (60% in the UK and 73% in Spain; p < 0.01). Conclusion: The results of this study suggest that it is necessary to encourage interdisciplinary collaboration between practitioners to improve referral of patients with suspected keratoconus to an ophthalmology specialist to change the course of this disease, to reduce keratoconus progression and visual acuity impairment and to minimize the impact of this disease on patients’ quality of life
