Introduction. The main objective of our study was to establish comparisons in the prediction of the maximum consumption of oxygen (VO2max in 3 field test; Universite de Montreal Track Test (UMTT), VAM-EVAL test and the 20m Shuttle Run Test (20m-SRT). As secondary objective it was to compare the speeds, the running distances and the duration among the test. Material and methods: 41 individuals (24 men and 17 women), students of physical education participated voluntarily. They were evaluated in 4 occasions; in the first place he was carried out the evaluation anthropometric in laboratory. In the following three opportunities they were evaluated aleatorily in field with the UMTT, VAM-EVAL and 20m-SRT.The differences and relationships between the VO2max predictive and other quantitative characteristics among the test were analyzed applying ANOVA respectively to 1 factor and the coefficient of correlation of Pearson. Results: In both groups differences were not observed in the VO 2max predictive between the VAM-EVAL and the UMTT, being for the group of the men 48,5±4,7 versus 49,1 ±4,6 ml·kg -1min-1 (p<0,05), and for the women 41,8±3,4 versus 42,3±3,2 ml·kg-1min-1. The VO 2max predictive the 20m-SRT, was inferior significantly with regard to the other test, being for the men 43,8±5,3 and for the women 34,2±4,5 ml-kg-1·min-1 (p <0,05). Conclusion: In students of physical education the VO2max predictive obtained from the 20m-SRT was inferior significantly with regard to the UMTT and to the VAM-EVAL, in both sexes. They were not difference statistically significant in the VO2max predictive between the UMTT and the VAM-EVAL. In both sexes, one observes a tendency to reach high speeds in the VAM-EVAL.

Objetive: The main objective of our study was to establish comparisons in the final speeds reached in two incremental and maximal tests; Universite de Montreal Track Test (UMTT) and VAM-EVAL Test. A secondary objective was to compare maximal oxygen consumption (VO2máx) predictions, running distances and the duration among both test. Method: Forty five physical education students (26 men and 19 women) participated voluntarily. They were evaluated in 3 sessions; first session, they were evaluated in anthropometry at the laboratory. In the two following evaluation sessions they were carried out aleatorily the field test UMTT and VAM-EVAL. The differences between maximal speeds and other quantitative characteristics for both tests were analyzed applying a Student t test for paired groups and between both tests were analyzed by the Pearson's coefficient of correlation. Results: The difference average in the VFA between the VAM-EVAL and UMTT was of 0,46 km·h-1. They were not significant differences in the VFA neither in none of the variables analyzed in both test: men 13,9 ± 1,3 versus 13,4 ± 1,4 km·h-1 and women 11,7 ± 1,0 versus 11,3 ± 1,0 km·h-1 (p > 0,05). The individual differences in the VFA between both test was inside the limits of agreement of 95% (-0,63-1,54 km·h-1). Conclusion: In students of physical education they were not differences statistically significant in the final speeds reached between the UMTT and VAM-EVAL. In a same way, they were not differences in the reached distances, the duration of the test and in the predictive VO2máx. © 2014 Revista Andaluza de Medicina del Deporte.

Introduction. A high level of physical fitness is associated with cardiovascular health in children and adolescents. At present, there is no systematic implementation of a test battery to assess physical fitness at schools in Argentina. The main objective of this study was to implement the ALPHA test battery to determine the physical fitness of a sample made up of Argentine children and adolescents and to establish the proportion of subjects whose aerobic capacity is indicative of future cardiovascular risk. Population and methods. A sample of 1867 participants (967 girls) aged 6 to 19.5 years old assessed using the ALPHA test battery. Four components of physical fitness were measured: 1) morphological component: height, body weight, and waist circumference; 2) musculoskeletal component: standing long jump test; 3) motor component: speed/agility test (4x10 m shuttle run); 4) cardiorespiratory component: coursenavette 20 m, shuttle run test and estimation of maximal oxygen consumption. The 5th, 25th, 50th, 75 th, and 95th percentiles were estimated for the main tests. Results. The mean body mass index was 20.8 kg/ m2, and 7.8% of participants were classified as obese. In addition, male participants had a better performance in all physical fitness tests when compared to girls (p< 0.001). An aerobic capacity indicative of cardiovascular risk was observed in 31.6% of all participants. Conclusions . Argentine male children and adolescents included in the sample showed higher levels of physical fitness. Such differences increase with age. Approximately one every three participants had an aerobic capacity indicative of future cardiovascular risk.

The Eocene Green River Formation in Fossil Basin, Wyoming provides a detailed record of the paleoecology and depositional history of ancient Fossil Lake. Fossil Lake was one of three Eocene lakes that formed an extensive lake system in Wyoming, Utah, and Colorado. It began as a flood-plain lake in the southern part of Fossil Basin and expanded northward as the lake evolved. Fossil Lake went through the major stages of lake evolution, including the overfilled (Road Hollow Member), balanced-fill (Fossil Butte Member), and underfilled (Angelo Member) stages. These stages are represented in the sedimentary record by a complete suite of lake-margin to lake-center facies. This study establishes the Road Hollow Member of the Green River Formation as representing the earliest stage of lake evolution in Fossil Lake. We also revise the boundaries for the Fossil Butte and Angelo Members of the Green River Formation, which clearly delineate the latest two stages of lake evolution. These revisions not only describe and add a previously unrecognized and thick sequence of lacustrine rocks in Fossil Basin, but help us to better understand the depositional systems that existed during each stage of lake evolution.

Introduction: The purpose of the study was to propose a correction chart for the prediction of the maximal speed aerobic (MAS) in the Course Navette of 20. metre test (CN-20. m) in both sexes. Material and methods: A total of 77 subjects (46 men and 31 women), physical education students, participated voluntarily. They were evaluated on 3 occasions, the first of which was an anthropometric assessment in the laboratory. On the following two occasions they were randomly assessed in the field using the CN-20. m test and the MAS-EVAL (T-MAS) test. The differences and relationships between the speeds and other quantitative characteristics of both tests were analysed by applying the Student t test for related samples, and the Pearson correlation coefficient. A linear regression analysis was performed to prepare the correction chart for prediction of the MAS. Results: The results showed that the speeds reached in the T-MAS (14.0 ± 1.4. km/h in men and 11.6 ± 1.0. km/h in women) were significantly higher than those obtained in the CN-20 m (12.0 ± 0,8. km/h in men and 10.3 ± 0,6. km/h in women) (PR .0001). There was a high correlation between the speeds for the males (r = 0,87) and moderate to high for the women (r = 0,77). The linear regression equation to predict the MAS starting from the speed reached in the CN-20. m was (1.468 · Vmax) - 3.597 in men, and (1.2 · Vmax) - 0,7 in women. Conclusions: Men and women reached significantly higher speeds in the T-MAS in comparison with the CN-20 m test. © 2011 Consell Català de l'Esport. Generalitat de Catalunya.

Background: The assessment of VO2max allow classify subjects according to the health risk. However the factors that may affect the classifications have been little studied. The main purpose was to determine whether the type of VO2max prediction equation and the Fitnessgram® criterion-referenced standards modified the proportion of young adults classified with a level of aerobic capacity cardiometabolic risk indicative. Methods: The study design was observational, cross-sectional and relational. Young adults (n= 240) participated voluntarily. The VO2max was estimated by 20-m shuttle run test applying 9 predictive equations. The differences in the classifications were analyzed with the Cochran Q and McNemar tests. Results: The level of aerobic capacity indicative of cardiometabolic risk ranged between 7.1% and 70.4% depending on the criterion-referenced standards and predictive equation used (p<0.001). A higher percentage of women were classified with an unhealthy level in all equations (women: 29.4% to 85.3% vs 4.8% to 51% in men), regardless of the criterion-referenced standards (p<0.001). Both sexes and irrespective of the equation applied the old criterion-referenced standards classified a lower proportion of subjects (men: 4.8% to 48.1% and women: 39.4% a 68.4%) with unhealthy aerobic capacity (p≤ 0.004). Conclusions: The type of VO 2max prediction equation and Fitnessgram® criterion-referenced standards changed classifications young adults with a level of aerobic capacity of cardiometabolic risk indicative.

The role of dietary fatty acids on cancer is still controversial. To examine the current literature on the protective role of conjugated linoleic acid (CLA) and marine long-chain fatty acids [eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] and the risk of breast and prostate cancer, data from 41 case-control and cohort studies and relevant in vitro and animal experiments were included in this 20002010 revision. Epidemiological studies on CLA intake or its tissue concentration related to breast and prostate tumorigenesis are not conclusive; EPA and DHA intake have shown important inverse associations just in some studies. Additional research on the analysed association is required. © 2011 Informa UK, Ltd.

This study aims at assessing the influence of the theoretical-technical orientation in the personal style of the therapist. 60 psychotherapists from psychoanalytic, cognitive and integrative orientation were studied. The Assessment of Personal Style of the Therapist Questionnaire (PST-Q) of Fernández-Álvarez & García (1998) and an exploratory interview about orientation and performance created for this study were administered. To assess the influence of the theoretical-technical orientation over the personal styles of the therapist, the multivariate analysis of variance (MANOVA) was used. The obtained results show statistically significant differences in the personal styles of the therapist according to theoretical-technical orientation, showing a characteristic profile if the orientation is psychoanalytic, cognitive or integrative. The results are especially relevant for the psychotherapist professional practice. © 2015 Fundación AIGLÉ.

The main objective of this study is providing information on the influence of emotional intelligence as a protective factor against compassion fatigue in therapists. The sample was composed of 158 Argentine psychologists and psychiatrists, working in the clinical area. The participants completed a sociodemographic characteristics test, Trait Meta- Mood Scale (TMMS-24), the Empathy Exhaustion Scale (ESAPE) and dimensions of perspective taking and empathic concern of the Interpersonal Reactivity Index (IRI). The data found by multiple linear regression analysis reveals that emotional intelligence is related to compassion fatigue, the dimensions of attention, and emotional repair proving to be especially important in the explained proportion of variance in vulnerability and professional involvement. © 2015 Fundación AIGLÉ.

The integrity of the thymus during early life is necessary for a proper maturation of the neuroendocrine system, including the adrenal axis. The thymic metallopeptide thymulin seems to be a central physiologic mediator of thymus-pituitary communication. Furthermore, neonatal thymulin gene therapy has been shown to prevent the typical alterations of gonadotrophic cell number and morphology and serum gonadotropin levels in nude female mice. In the present study we assessed the impact of athymia and the effect of neonatal thymulin gene therapy on the corticotropic cell population in nude mice. The effect of thymulin administration to adult nudes on their hypothalamic content of corticotropin-releasing hormone (CRH) and the adrenal content of corticosterone was also determined. We used an adenoviral vector expressing a synthetic gene for the thymic peptide thymulin (metFTS) termed RAd-FTS. On postnatal day 1 or 2, heterozygous (nu/+) and homozygous (nu/nu) pups of both sexes received a single bilateral i.m. injection of RAd-FTS or RAd-GFP, a control vector. On postnatal day 71, mice were bled and sacrificed, and their pituitaries were immediately dissected, fixed and immunostained for corticotropin. Morphometry was performed by means of an image-analysis system. The following parameters were calculated: Volume density (VD: σ cell area/reference area), cell density (CD: Number of cells/reference area), and cell surface (CS: Expressed in μm2). Serum thymulin levels were measured by a bioassay, and CRH as well as corticosterone were determined by IRMA and RIA, respectively. Neonatal thymulin gene therapy in the athymic mice restored their serum thymulin levels and increased corticotrope CD, VD and CS in both control and athymic mice. Athymic mice showed only a marginal reduction in corticotrope CD, VD and CS. In these mutants hypothalamic CRH content was slightly increased, whereas adrenal corticosterone tended to be lower. Thymulin administration to adult mice tended to reverse these changes. Our results suggest a possible modulating effect of thymulin on the corticotrope population and the adrenal gland, confirming the existence of a bidirectional thymus-pituitary-adrenal axis.
