Physical Exercise Program for Elderly Subjects in the “Club Nueva Vida”, in Tunja City

A descriptive, case series intervention study was performed to identify changes in physical qualities, aerobic power, flexibility, strength and body composition amongst 20 elderly subjects belonging to the “Club Nueva Vida” in Tunja City, during the second period of 2005. A PRE and POST assessment of their physical qualities was applied after a 16 week physical exercise program.Results showed an increase in the average of the static muscle streneth from 0.27 to 0.30 Newtons. Standard deviation diminished in 0.1. The dynamic strength measure by the push up test improved in 10% a 35% improved in 10% a 35% improved their. Cardiovascular capability until to high levels of 80% there were not significant changes in the body weight between measures taken before and after the program application. The results obtained with the sit and reach test did not show statistically significant differences. Hower in other flexibility tests the results changed from bad ranges to middle and good ones. The enrolled population was stable during the development of the exercise program. This study concludes that elderly adults acquire changes in their physical quality features after exercise intervention. Physical exercise programs in elderly adults must involve strength activities for upper limbs, trunk and aerobic power activities. The “Beliefs Health Model” is a adherence to reach compliance and maintenance in physical exercise.

Scandalous Subjects

This essay explores the problems and possibilities of the postcolonial as word and orientation, as category and entity. It sieves postcolonial expressions through critical filters to make two tasks palpable. On the one hand, faced forthwith are the scandals of the nation and the West as well as the outrage of the postcolonial itself. On the other hand, brought to the front are protocols of probing that do not merely lead to an undoing of “foundations” but point to procedures of critical affirmation embedded within a history without guarantee. Here are to be found dispositions that carefully question and prudently elaborate issues of power and difference, authority and alterity, including through critical considerations of modernity and its philosophical and historical discussions in the West.-----Este artículo explora los problemas y posibilidades de lo postcolonial en tanto que concepto y orientación, categoría y entidad. Tamiza las expresiones postcoloniales a través de los filtros de la crítica para lograr que dos tareas devengan palpables. Por una parte, a lo primero que nos enfrentamos es a los escándalos de la nación y de Occidente, así como al ultraje de lo postcolonial en sí mismo. Por otra parte, se destacan protocolos de investigación que no conducen simplemente a un menoscabo de los ‘fundamentos’ sino que apuntan a procedimientos de afirmación crítica enraizados en lo que yo llamo una historia sin garantía. Aquí se encuentran disposiciones que cuestionan de manera juiciosa y elaboran con prudencia asuntos de poder y diferencia, autoridad y alteridad y que incluyen consideraciones críticas de la modernidad y sus discusiones filosóficas e históricas en Occidente.

Science : teaching school subjects 11-19.

Este libro se centra en la enseñanza de las ciencias en la escuela a alumnos con edades comprendidas entre los once y diecinueve años. Desarrolla como tema principal la idea de que la ciencia en la escuela es una entidad con su propia identidad, con pocos elementos en común con la ciencia misma. Es decir, es una materia de enseñanza impartida por miembros de la profesión docente en instituciones educativas. En este contexto escolar, se examinan tanto la evolución de la ciencia en el futuro, las competencias profesionales de los profesores como, en su aprendizaje se refleja la investigación educativa.

The perception of vowels in hearing and hearing-impaired subjects

This paper examines the relationship between speech discrimination ability and vowel map accuracy and vowel map size.

Frequency responses of hearing aids and their effects on the speech perception of eight hard-of-hearing subjects

This dissertation examines the relationship between frequency response and word-discrimination performance of hearing-impaired persons. Three questions are addressed: does the restoration of the normal field-to-eardrum transfer function improve word discrimination; is the restoration of the normal shape of the audibility curve (uniform hearing level at all frequencies) beneficial to hearing-impaired listeners; and can speech discrimination be improved by an extension of the present narrow-band response in hearing aids.

Dietary glycated protein modulates the colonic microbiota towards a more detrimental composition in ulcerative colitis patients and non-ulcerative colitis subjects

AIM: To investigate the effect of native, heated and glycated bovine serum albumin (BSA) on the ulcerative colitis (UC) and non-UC colonic microbiota in vitro. METHODS AND RESULTS: Continuous flow culture (CFC) models of the human colonic microbiota inoculated with faeces from UC and non-UC volunteers were maintained on BSA as growth substrate. Changes in bacterial populations and short-chain fatty acids were determined. UC and non-UC microbiota differed significantly in microbial populations, with elevated numbers of sulfate-reducing bacteria (SRB) and clostridia in the microbiota from UC patients. Compared with native BSA, glycated BSA modulated the gut microbiota of UC patients in vitro towards a more detrimental community structure with significant increases in putatively harmful bacteria (clostridia, bacteroides and SRB; P < 0.009) and decreases in dominant and putatively beneficial bacterial groups (eubacteria and bifidobacteria; P < 0.0004). The levels of beneficial short-chain fatty acids were significantly decreased by heated or glycated BSA, but were increased significantly by native BSA. CONCLUSION: The UC colonic microbiota maintained in CFC was significantly modified by glycated BSA. SIGNIFICANCE AND IMPACT OF THE STUDY: Results suggest that dietary glycated protein may impact upon the composition and activity of the colonic microbiota, an important environmental variable in UC.

Long-term monounsaturated fatty acid diets reduce platelet aggregation in healthy young subjects

The aim of the present study was to compare the response of a range of atherogenic and thrombogenic risk markers to two dietary levels of saturated fatty acid (SFA) substitution with monounsaturated fatty acids (MUFA) in students living in a university hall of residence. Although the benefits of such diets have been reported for plasma lipoproteins in high-risk groups, more needs to be known about effects of more modest SFA-MUFA substitutions over the long term and in young healthy adults. In a parallel design over 16 weeks, fifty-one healthy young subjects were randomised to one of two diets: (1) a moderate-MUFA diet in which 16 g dietary SFA/100 g total fatty acids were substituted with MUFA (n 25); (2) a high-MUFA diet in which 33 g dietary SFA/100 g total fatty acids were substituted with MUFA (n 26). All subjects followed an 8-week run-in diet (reference diet), with a fatty acid composition close to the UK average values. There were no differences in plasma lipid responses between the two diets over 16 weeks of the study with similar reductions in total cholesterol (P<0.001) and LDL-cholesterol (P<0.01) in both groups; a small but significant reduction in HDL-cholesterol was also observed in both groups (P<0.01). Platelet responses to ADP (P<0.01) and arachidonic acid (P<0.05) differed with time on the two diets; at 16 weeks, platelet aggregatory response to ADP was significantly lower on the high-MUFA than the moderate-MUFA (P<0.01) diet; ADP responses were also significantly lower within this group at 8 (P< 0.05) and 16 (P< 0.01) weeks compared with baseline. There were no differences in fasting factor VII activity (factors VIII and VIIag), fibrinogen concentration or tissue-type plasminogen activator activity between the diets. There were no differences in postprandial factor VIII responses to a standard meal (area under the curve) between the diets after 16 weeks, but postprandial factor VIII response was lower than on the high-MUFA diet compared with baseline (P<0.01). In conclusion, a high-MUFA diet sustains potentially beneficial effects on platelet aggregation and postprandial activation of factor VII. Moderate or high substitution of MUFA for SFA achieves similar reductions in fasting blood lipids in young healthy subjects.
