Abstract: several self-report questionnaires have been used to evaluate various determiners of sports practice in young people, but very few have been applied to mexicans. in this analysis, the questionnaire was administered to 222 subjects (13-25 years). we determined its internal consistency (cronbach α), content validity (document analysis), construct (exploratory factor analysis, efa) as well as that of the criterion. the latter, by its correlation (spearman) with anthropometric variables: body mass index (bmi) and waist circumference (wc) and physiological (vo2max). the results showed that the internal consistency is acceptable (cronbach's α = 0.68 to 0.85). moreover, this questionnaire similarly responds to queries posed in surveys already reported (to find out the physical, educational, psychological and socio-demographic characteristics of physical/sports practice). the efa showed 1, 2 and 3 factor structures with adequate cronbach's α (~0.70) and kaiser-meyer-olkin (~0.72) values. the practice of physical activity was associated with a lower bmi and higher vo2max. the questionnaire proved to be a valid instrument for investigating physical/sports habits and behavior in young people from northern mexico.
The Respiratory Exchange Ratio is Associated with Fitness Indicators Both in Trained and Untrained Men: A Possible Application for People with Reduced Exercise Tolerance

Clinical Medicine : Circulatory, Respiratory and Pulmonary Medicine , 2008,
Abstract: Background: The respiratory exchange ratio (RER) indirectly shows the muscle′s oxidative capacity to get energy. Sedentarism, exercise and physically active lifestyles modify it. For that reason, this study evaluates the associations between RER during sub-maximum exercise and other well established fitness indicators (body fat, maximum heart rate, maximum O2 uptake, workload, and lactate threshold), in physically active trained and untrained men.Methods: The RER, O2 uptake and blood lactate were measured in eight endurance trained and eight untrained men (age, 22.9 ± 4.5 vs. 21.9 ± 2.8 years; body mass, 67.1 ± 5.4 vs. 72.2 ± 7.7 kg; body fat, 10.6 ± 2.4% vs. 16.6 ± 3.8% and maximum O2 uptake, 68.9 ± 6.3 vs. 51.6 ± 5.8 ml kg 1 min 1), during maximum exercise test and during three different sub-maximum exercises at fixed workload: below, within or above the lactate threshold.Results: Endurance trained men presented higher O2 uptake, lower blood lactate concentrations and lower RER values than those in untrained men at the three similar relative workloads. Even though with these differences in RER, a strong association (p < 0.05) of RER during sub-maximum exercise with the other well established fitness indicators was observed, and both maximum O2 uptake and lactate threshold determined more than 57% of its variance (p < 0.05).Conclusions: These data demonstrate that RER measurement under sub-maximum exercise conditions was well correlated with other established physical fitness indicators, despite training condition. Furthermore, the results suggest that RER could help obtain an easy approach of fitness status under low exercise intensity and could be utilized in subjects with reduced exercise tolerance.

Abstract: Introducción: Estudios sobre el estado de salud y nutrición de Mexicanos con discapacidad intelectual (DI) incluyendo aquellos con Síndrome de Down (SD), son escasos. Objetivo: Analizar algunos factores fisiológicos y sociales asociados a la masa corporal de jóvenes con DI del norte de México. Métodos: A 57 jóvenes con DI (17 ± 5 a os, SD = 16%) y al menos uno de sus tutores, se les midió su peso, talla, y otras variables antropométricas. Se determinó su IMC (kg/m2), somatotipo y estado nutricio mediante 3 criterios internacionales y glucosa, colesterol total y triacilglicéridos plasmáticos. Al tutor se le aplicó un cuestionario socioeconómico, de inseguridad alimentaria y conocimientos de nutrición. Resultados: Los participantes con SD eran 12 cm más peque os y median 6 mm más de pliegue subscapular (PSECP) que aquellos con otra DI (p < 0,05). El sobrepeso-obesidad estuvo presente en 70 y 44%, respectivamente. Los parámetros bioquímicos fueron similares entre grupos, pero 25% tenía alguna dislipidemia. El IMC del participante correlacionó (p < 0,01) con varios indicadores antropométricos y de adiposidad (r = 0,40 a 0,88), plasmáticos [triacilglicéridos (r = 0,48), colesterol total (r = 0,44)] y edad del participante y tutor (r = 0,35). El gasto en alimentos correlaciono con PSECP del participante (r = -0,33, p < 0,05). La circunferencia de cadera, cintura, pantorrilla y PSECP, explicaron el 89% de la varianza del IMC. Conclusión: La masa corporal de jóvenes con DI del norte de México se relaciona fuertemente con el grado de adiposidad corporal, con dislipidemias y con factores socioeconómicos de su entorno familiar. Introduction: Studies on the state of health and nutrition of Mexicans with intellectual disability (ID) including those with Down syndrome (DS), are scarce. Objective: To analyze some physiological and social factors associated with the body mass of young people with ID from northern México. Methods: Body weight, height and other anthropometric values were measured in fifty seven young (17 ± 5 years) participants with ID (DS,16%) and at least one guardian. BMI (kg/m2), somatotype and nutritional status were established by three international standards and total blood glucose, cholesterol & triacylglycerides, were also analyzed. Guardian's socio-economic, household food insecurity and nutrition literacy status were estimated with validated questionnaires by direct interview. Results: Participants with SD were 12 cm smaller but subscapular skinfold (SECPS) was 6 mm thicker than that from other ID participants (p < 0.05). Prevalence of overwe

Abstract: Introducción. En el marco de un nuevo modelo educativo formativo, la Universidad San Sebastián apunta al desarrollo de estrategias pedagógicas que sitúan al estudiante en el centro de las acciones. Es así como surge la necesidad de incrementar la motivación en los jóvenes que ingresan a la carrera de medicina, profesión desde siempre ligada a los valores sociales y el altruismo. Este trabajo explora la relevancia del contacto temprano con el paciente y el hospital como fuentes de motivación en primer a o. Sujetos y métodos. Todos los estudiantes de primer a o de medicina (n = 115) fueron invitados a visitar voluntariamente un hospital. Allí, los estudiantes recorrieron el establecimiento y sostuvieron una conversación libre con un paciente. Las opiniones se recogieron a través de un escrito libre. Resultados. Se inscribieron 95 estudiantes, de los cuales 68 concurrieron a la visita. Al consultar sobre la vivencia con el paciente, los estudiantes se refirieron positivamente a ésta. La ansiedad al inicio de la conversación fue uno de los aspectos más mencionados, al igual que la importancia de conocer el futuro lugar de trabajo. Conclusiones. La experiencia evidenció un alto interés en participar. Asimismo reveló elementos de la vida afectiva de los estudiantes, pilar fundamental de la educación médica. Finalmente, se aconseja la temprana relación con el paciente y con el hospital como agentes motivacionales en primer a o. Se sugiere incorporar tareas y complementar la evaluación con herramientas que permitan obtener información objetiva sobre los aprendizajes adquiridos. Introduction.

Abstract: under charismatic and populist leadership, chavez?s and chavismo bolivarian experiment in the government move between misgovernment and authoritarianism. the relevance of this political formula, in venezuela?s experience during the last years, has been observed, if not adopted, by other recent experiences in the andean democracy, as a successful alternative facing the announced failure of representative democracy. through the flag and symbols of a rhetorical bolivarism, combined with a sort of "socialism of the 21st century," they aim to encourage what they call "the bolivarian revolution." my purpose in this article is to analyze such phenomenon based on the election and referendum results after chavez?s reelection in december 2006.

Alfredo RAMOS JIMéNEZ
América Latina Hoy , 2009,
Abstract: RESUMEN: El autor se propone en este ensayo destacar ciertos aspectos del funcionamiento de los partidos que resultan claves para entender el proyecto más general de la democratización del Estado en América Latina. Como conclusión final se se ala la necesidad de ampliar el espacio de los partidos políticos en una doble dirección: en el de la proyección de la cultura democrática con fines de socialización del poder económico y político y en el de la promoción de una nueva clase política, dispuesta a la ampliación de la participación de los ciudadanos en la toma de decisiones. ABSTRACT: The author marks several keys issues about political parties and the process of state democratization in Latin America. The final conclusion is to nide the political parties espace in two ways: first, the rise of a civic and democracit political culture; second, the rise of a new political class who allow the popular participation in the decission taking process.
La "revolución" que no fue. Desgobierno y autoritarismo en la Venezuela de Chávez The Revolution that Never Took Place. Misgovernment and Authoritarianism in Chavez’s Venezuela
Alfredo Ramos Jiménez
Estudios Políticos , 2011,
Abstract: Bajo el liderazgo carismático y plebiscitario, el experimento bolivariano de Chávez y del chavismo en el poder se mueve entre el desgobierno y el autoritarismo. La relevancia de esta fórmula política, en la experiencia de Venezuela en los a os recientes, ha sido observada, si no adoptada, en otras experiencias recientes en las democracias andinas, como una alternativa exitosa frente al denunciado fracaso de la democracia representativa. Con las banderas y símbolos de un bolivarianismo retórico, que se combina con un indeterminado "socialismo del siglo xxi", se ha pretendido impulsar lo que se ha convenido en llamar "revolución bolivariana". En este artículo me propongo como objetivo interpretar tal fenómeno a partir de los resultados de las elecciones y referendos después de la reelección de Chávez en diciembre de 2006. Under charismatic and populist leadership, Chavez’s and Chavismo Bolivarian experiment in the government move between misgovernment and authoritarianism. The relevance of this political formula, in Venezuela’s experience during the last years, has been observed, if not adopted, by other recent experiences in the Andean democracy, as a successful alternative facing the announced failure of representative democracy. Through the flag and symbols of a rhetorical Bolivarism, combined with a sort of "socialism of the 21st century," they aim to encourage what they call "the Bolivarian revolution." My purpose in this article is to analyze such phenomenon based on the election and referendum results after Chavez’s reelection in December 2006.
