Sacrificio y sociabilidad en el entrenamiento de nadadores master

El presente artículo analiza la manera en que la participación en los entrenamientos de un conjunto de nadadores master (adultos) expresa tanto una disposición hacia la actividad corporal como hacia la sociabilidad con los pares. Asimismo, se muestra el modo en que tiene lugar el proceso de aprendizaje de una técnica corporal de una manera práctica y colectiva durante el entrenamiento y los sentidos específicos que adquieren las nociones de sufrimiento y sacrificio en dicho proceso. Para ello se utiliza una estrategia de abordaje empírico basado en técnicas cualitativas de producción y análisis de datos, realizando entrevistas y a la vez trabajo de campo etnográfico

La enseñanza de una técnica del cuerpo mezcla permanentemente el gesto y la palabra, el ejemplo y su explicación : Entrevista a David Le Breton

En la presente entrevista a David Le Breton, Doctor en Sociología de la Universidad París VII y Profesor en la Facultad de Ciencias Sociales de la Universidad 'Marc Bloch' de Estrasburgo (Francia), se desarrolla un diálogo con Eduardo Galak en el que se discuten las problemáticas del cuerpo y de la enseñanza de las técnicas corporales según la mirada de este autor. Más aún, resultan relevantes los análisis realizados por Le Breton sobre la Educación Física, desarrollando su pensamiento sobre los juegos, las gimnasias y los deportes. A su vez, a través de un contrapunto entre el entrevistador y el entrevistado sobre la potencialidad del concepto habitus para la investigación de las prácticas corporales, se puede observar el posicionamiento teórico de uno de los principales referentes bibliográficos en materia de estudios sociales sobre el cuerpo. Entonces, en este escrito se encuentra no sólo un recorrido por la obra del autor sino que además se profundizan algunos puntos ciegos de su bibliografía sobre el cuerpo y las prácticas corporales

Propuestas desde la antropología para el abordaje de las dimensiones socio-culturales del cuerpo : Un aporte al debate Educación Física / Educación Corporal

El objetivo de este artículo es realizar un aporte desde la Antropología socio-cultural al debate que se está dando entre Educación Física y Educación Corporal. Dado el énfasis de esta última perspectiva por incluir en sus prácticas la consideración de que el cuerpo no es asimilable al organismo biológico y que es indisoluble de los contextos socio-culturales, haré referencia a la noción contemporánea de cultura y a los debates que se han dado en la Antropología acerca de la distinción entre naturaleza y cultura. Junto con este problema, y haciéndome eco del interés actual en el campo de la Educación Corporal por analizar las diferencias entre las nociones de organismo y de cuerpo, y sus implicancias en las prácticas de las profesoras y los profesores del área, revisaré las conceptualizaciones socio-antropológicas sobre el cuerpo, distinguiendo diferentes líneas de abordaje sobre lo corporal. Para ejemplificar esta problemática, haré referencia a la concepción pionera de Marcel Mauss de "técnicas corporales"

PRÁTICAS RELIGIOSAS, CORPO E ESTILOS DE VIDA: UMA ANÁLISE COMPARATIVA ENTRE EVANGÉLICOS NO BAIRRO RUDGE RAMOS EM SÃO BERNARDO DO CAMPO

A presente pesquisa analisa o corpo como parte de um processo de construção social e busca compreender as implicações da relação entre essa construção social do corpo e práticas religiosas evangélicas. Elege as Igrejas Congregação Cristã, Presbiteriana e Renascer em Cristo no bairro de Rudge Ramos, em São Bernardo do Campo, como objeto de investigação dessa questão. Essa relação está envolta em intenções e manifestações corporais que implicam práticas religiosas e os estilos de vida das pessoas que freqüentam as referidas denominações no bairro em questão. O estudo desenvolve um mapeamento das técnicas corporais que significam a maneira como as pessoas se valem dos seus corpos. Na apreciação dos aspectos sociais, culturais e econômicos relacionados ao bairro em questão e às igrejas nele inseridas, procuramos compreender a maneira como essas três tradições evangélicas desenvolvem técnicas corporais diferenciadas. Também, se as pessoas que freqüentam essas igrejas sofrem alguma influência do modelo de corporeidade da sociedade atual que tem como pretensão a busca pela ascensão social e por condições de consumo vinculadas ao corpo.(AU)

A experiência no Tai Chi: possibilidades para pensar o corpo sem órgãos e a preparação do ator

Although research in the field of performing arts has substantially advanced over the last century, the actor, in general, still needs a repertoire of specific references to guide or support his practice. But how the actor must work the material foundation of his art that is his own body? Starting from a prerogative of a idiosyncrasy that is part of theater, this study intend, from the description and reflection about one physical experience with the Tai Chi, to weave relations between this experience and the possible developments of acting preparation. This research is also aimed to highlight the elements of connection between the principles that rules Tai Chi and the body without organs, idealized by Artaud, with the perspective of pointing possible contributions for actors work. The work presented here refers to a qualitative study that considers the body experience in practice of Tai Chi as a reference to dialogue and reflect about the acting preparation. The process of acting preparation presupposes a constant redoing of the body by certain practices. My experience with Tai Chi within this research allowed me verify that the work from established body techniques could be a way of technical preparation for the actor. As the body conscience expands, Tai Chi promotes a greater freedom of creation and expression, giving the actor the possibility of experience the body without organs, the artistic equivalent of the daily body, present, conscious, the organic foundation of emotions, in wich it is possible the materiality of ideas

Comparative In vitro Mechanical Evaluation Of Techniques Using A 2.0 mm Locking Fixation System For Simulated Fractures Of The Mandibular Body.

To perform a comparative evaluation of the mechanical resistance of simulated fractures of the mandibular body which were repaired using different fixation techniques with two different brands of 2.0 mm locking fixation systems. Four aluminum hemimandibles with linear sectioning simulating a mandibular body fracture were used as the substrates and were fixed using the two techniques and two different brands of fixation plate. These were divided into four groups: groups I and II were fixed with one four-hole plate, with four 6 mm screws in the tension zone and one four-hole plate, with four 10 mm screws in the compression zone; and groups III and IV were fixed with one four-hole plate with four 6 mm screws in the neutral zone. Fixation plates manufactured by Tóride were used for groups I and III, and by Traumec for groups II and IV. The hemimandibles were submitted to vertical, linear load testing in an Instron 4411 servohydraulic mechanical testing unit, and the load/displacement (3 mm, 5 mm and 7 mm) and the peak loads were measured. Means and standard deviations were evaluated applying variance analysis with a significance level of 5%. The only significant difference between the brands was seen at displacements of 7 mm. Comparing the techniques, groups I and II showed higher mechanical strength than groups III and IV, as expected. For the treatment of mandibular linear body fracture, two locking plates, one in the tension zone and another in the compression zone, have a greater mechanical strength than a single locking plate in the neutral zone.

New techniques in nutritional assessment: body composition methods

New techniques in air-displacement plethysmography seem to have overcome many of the previous problems of poor reproducibility and validity. These have made body-density measurements available to a larger range of individuals, including children, elderly and sick patients who often have difficulties in being submerged underwater in hydrodensitometry systems. The BOD POD air-displacement system (BOD POD body composition system; Life Measurement Instruments, Concord, CA, USA) is more precise than hydrodensitometry, is simple and rapid to operate (approximately 1 min measurements) and the results agree closely with those of hydrodensitometry (e.g. +/-3.4% for estimation of body fat). Body line scanners employing the principles of three-dimensional photography are potentially able to measure the surface area and volume of the body and its segments even more rapidly (approximately 10 s), but the validity of the measurements needs to be established. Advances in i.r. spectroscopy and mathematical modelling for calculating the area under the curve have improved precision for measuring enrichment of (H2O)-H-2 in studies of water dilution (CV 0.1-0.9% within the range of 400-1000 mu l/l) in saliva, plasma and urine. The technique is rapid and compares closely with mass spectrometry (bias 1 (SD 2) %). Advances in bedside bioelectrical-impedance techniques are making possible potential measurements of skinfold thicknesses and limb muscle mass electronically. Preliminary results suggest that the electronic method is more reproducible (intra-and inter-individual reproducibility for measuring skinfold thicknesses) and associated with less bias (+ 12%), than anthropometry (+ 40%). In addition to these selected examples, the 'mobility' or transfer of reference methods between centres has made the distinction between reference and bedside or field techniques less distinct than in the past.

[health Protection For Rural Workers: The Need To Standardize Techniques For Quantifying Dermal Exposure To Pesticides].

Quantification of dermal exposure to pesticides in rural workers, used in risk assessment, can be performed with different techniques such as patches or whole body evaluation. However, the wide variety of methods can jeopardize the process by producing disparate results, depending on the principles in sample collection. A critical review was thus performed on the main techniques for quantifying dermal exposure, calling attention to this issue and the need to establish a single methodology for quantification of dermal exposure in rural workers. Such harmonization of different techniques should help achieve safer and healthier working conditions. Techniques that can provide reliable exposure data are an essential first step towards avoiding harm to workers' health.

Analysis Of The Fluorescence Of Body Fluids On Different Surfaces And Times.

The use of screening techniques, such as an alternative light source (ALS), is important for finding biological evidence at a crime scene. The objective of this study was to evaluate whether biological fluid (blood, semen, saliva, and urine) deposited on different surfaces changes as a function of the age of the sample. Stains were illuminated with a Megamaxx™ ALS System and photographed with a Canon EOS Utility™ camera. Adobe Photoshop™ was utilized to prepare photographs for analysis, and then ImageJ™ was used to record the brightness values of pixels in the images. Data were submitted to analysis of variance using a generalized linear mixed model with two fixed effects (surface and fluid). Time was treated as a random effect (through repeated measures) with a first-order autoregressive covariance structure. Means of significant effects were compared by the Tukey test. The fluorescence of the analyzed biological material varied depending on the age of the sample. Fluorescence was lower when the samples were moist. Fluorescence remained constant when the sample was dry, up to the maximum period analyzed (60 days), independent of the substrate on which the fluid was deposited, showing the novelty of this study. Therefore, the forensic expert can detect biological fluids at the crime scene using an ALS even several days after a crime has occurred.

Spontaneous transitions in the coordination of a whole body task

This paper describes an example of spontaneous transitions between qualitatively different coordination patterns during a cyclic lifting and lowering task. Eleven participants performed 12 trials of repetitive lifting and lowering in a ramp protocol in which the height of the lower shelf was raised or lowered 1 cm per cycle between 10 and 50 cm. Two distinct patterns of coordination were evident: a squat technique in which moderate range of hip, knee and ankle movement was utilised and ankle plantar-flexion occurred simultaneously with knee and hip extension; and a stoop technique in which the range of knee movement was reduced and knee and hip extension was accompanied by simultaneous ankle dorsi-flexion. Abrupt transitions from stoop to squat techniques were observed during descending trials, and from squat to stoop during ascending trials. Indications of hysteresis was observed in that transitions were more frequently observed during descending trials, and the average shelf height at the transition was 5 cm higher during ascending trials. The transitions may be a consequence of a trade-off between the biomechanical advantages of each technique and the influence of the lift height on this trade-off.

Velocimetry and thermometry of supersonic flow around a cylindrical body

The supersonic flow around a cylindrical body has been studied using two optical techniques. For both sets of measurements, the cylinder was mounted from the side of the tunnel, allowing investigation of the bow shock region as well as in the wake. A new technique, laser-enhanced ionization flow tagging, was used for streamwise velocity determinations behind the body. From these measurements, it was found that the downstream velocity outside the wake was (1.90 +/- 0.06) km/s, whereas inside the wake the velocity was about 0-500 m/s in the upstream direction. Planar laser induced fluorescence of nitric oxide was employed for temperature determinations. It was established that the freestream temperature was (2120 +/- 100) K, decreasing to around (1550 +/- 400) K in the wake.

Laparoscopic treatment of type 2 diabetes mellitus for patients with a body mass index less than 35

Background Type 2 diabetes mellitus (T2DM) is a common disease with numerous complications. Bariatric surgery is an efficient procedure for controlling T2DM in morbidly obese patients. In T2DM, the incretin effect is either greatly impaired or absent. This study aimed to evaluate the preliminary results from interposing a segment of ileum into the proximal jejunum associated with a sleeve or diverted sleeve gastrectomy to control T2DM in patients with a body mass index (BMI) less than 35 kg/m(2). Methods For this study, 39 patients (16 women and 23 men) underwent two laparoscopic procedures comprising different combinations of ileal interposition into the proximal jejunum via a sleeve or diverted sleeve gastrectomy. The mean age of these patients was 50.3 years (range, 36-66 years). The mean BMI was 30.1 kg/m(2) (range, 23.4-34.9 kg/m(2)). All the patients had a diagnosis of T2DM that had persisted for at least 3 years and evidence of stable treatment with oral hypoglycemic agents or insulin for at least 12 months. The mean duration of T2DM was 9.3 years (range, 3-22 years). Results The mean operative time was 185 min, and the median hospital stay was 4.3 days. Four major complications occurred in the short term (30-days), and the mortality rate was 2.6%. The mean postoperative follow-up period was 7 months (range, 4-16 months), and the mean percentage of weight loss was 22%. The mean postoperative BMI was 24.9 kg/m(2) (range, 18.9-31.7 kg/m2). An adequate glycemic control was achieved for 86.9% of the patients, and 13.1% had important improvement. The patients whose glycemia was not normalized were using a single oral hypoglycemic agent. No patient needed insulin therapy postoperatively. All the patients except experienced normalization of their cholesterol levels. Targeted triglycerides levels were achieved by 71% of the patients, and hypertension was controlled for 95.8%. Conclusions The laparoscopic ileal interposition via either a sleeve gastrectomy or diverted sleeve gastrectomy seems to be a promising procedure for the control of T2DM and the metabolic syndrome. A longer follow-up period is needed.
