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.

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. Source

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 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. Source

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.
