The current study investigated whether a single bout of concurrent exercise (Ex Rx) at Third Age Academies (TAAs) in Rio de Janeiro City meets the American College of Sports Medicine (ACSM) guidelines for energy cost and metabolic intensity in older adults. Nine subjects (5 males and 4 females, 63–80 years of age) visited the laboratory for clinical screening and for anthropometrical, resting, and maximal oxygen uptake assessments. Thereafter, subjects performed an Ex Rx circuit consisting of a single circuit alternating aerobic and resistance exercises with outdoor exercise equipment using body mass as the load (total of 9 exercises, 1–2 sets of 15 repetitions). Expired gases were collected via a metabolic cart during exercise bouts. The mean observed energy cost value of 169.1 kcal was slightly greater than the minimum value of 150 kcal reported in the ACSM guidelines (p = 0.018). Like energy cost, all the intensity markers adopted to analyze the physiological strain induced by the Ex Rx circuit significantly exceeded their reference values for moderate intensity (reference values: 3.2 METs (mean observed value = 4.6 METs, p = 0.002); 40% of oxygen uptake reserve (mean observed value = 51.5%, p = 0.040); 40% of heart rate reserve (mean observed value = 64.1%, p < 0.001)), according to the ACSM guidelines. In conclusion, a single bout of Ex Rx circuit performed at TAAs in Rio de Janeiro City was able to induce a physiological strain (i.e., energy cost and intensity) compatible with ACSM recommendations for eliciting health benefits among older adults.

This paper aims to show and to discuss some results of a large-time resarch upon the ergonomics problems of fishing in Cabo Frio, 200 km north far from Rio de Janeiro city. By working in a combined Ergonomic Action, Research-Action and Design Methodology perspective, we've looked for establishing the requisites and restraints concerning fishing boat projects, focusing the aspect of habitableness in a sea ambience, because the fishing boat is the workplace in this environment, and that makes it different from boats related to charge or people sea transport.

Background: The purpose of this study was to investigate the accuracy of the published prediction equations for determining level overground walking energy cost in young adults. Methods: In total, 148 healthy young adults volunteered to participate in this study. Resting metabolic rate and energy expenditure variables at speeds of 4, 5, and 6 km/h were measured by indirect calorimetry, walking energy expenditure was estimated by 3 published equations. Results: The gross and net metabolic rate per mile of level overground walking increased with increased speed (all P < .01). Females were less economical than males. The present findings revealed that the American College of Sports Medicine and Pandolf et al equations significantly underestimated the energy cost of overground walking at all speeds (all P < .01) in young adults. The percentage mean bias for American College of Sports Medicine, Pandolf et al, and Weyand et al was 12.4%, 16.8%, 1.4% (4 km/h); 21.6%, 15.8%, 7.1% (5 km/h); and 27.6%, 12%, 6.6% (6 km/h). Bland–Altman plots and prediction error analysis showed that the Weyand et al was the most accurate in 3 existing equations. Conclusions: The Weyand et al equation appears to be the most suitable for the prediction of overground walking energy expenditure in young adults.

OBJECTIVE To analyze the temporal evolution of the hospitalization of older adults due to ambulatory care sensitive conditions according to their structure, magnitude and causes. METHODS Cross-sectional study based on data from the Hospital Information System of the Brazilian Unified Health System and from the Primary Care Information System, referring to people aged 60 to 74 years living in the state of Rio de Janeiro, Souhteastern Brazil. The proportion and rate of hospitalizations due to ambulatory care sensitive conditions were calculated, both the global rate and, according to diagnoses, the most prevalent ones. The coverage of the Family Health Strategy and the number of medical consultations attended by older adults in primary care were estimated. To analyze the indicators’ impact on hospitalizations, a linear correlation test was used. RESULTS We found an intense reduction in hospitalizations due to ambulatory care sensitive conditions for all causes and age groups. Heart failure, cerebrovascular diseases and chronic obstructive pulmonary diseases concentrated 50.0% of the hospitalizations. Adults older than 69 years had a higher risk of hospitalization due to one of these causes. We observed a higher risk of hospitalization among men. A negative correlation was found between the hospitalizations and the indicators of access to primary care. CONCLUSIONS Primary healthcare in the state of Rio de Janeiro has been significantly impacting the hospital morbidity of the older population. Studies of hospitalizations due to ambulatory care sensitive conditions can aid the identification of the main causes that are sensitive to the intervention of the health services, in order to indicate which actions are more effective to reduce hospitalizations and to increase the population’s quality of life.

Levels of persistent organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in the blood serum of people living and working in the urban area of greater Rio de Janeiro city. Blood samples from 33 volunteers (16 males, 17 females, 19-63 years old) were taken in January 1999. OCP residues (op'DDT, pp'DDT, pp'DDD, pp'DDE, Aldrin, Dieldrin, Endrin, Heptachlor, Heptachlor-epoxide, alpha-, beta- and gamma-Hexachlorocyclo-hexane, Hexachlorobenzene) and PCBs (congeners: 28, 52, 101, 138, 153, 180) were extracted with n-hexane and analyzed by gas chromatography with electron capture detection. Except for pp'DDE (detection limit = 1.4µg/L) no other OCP residue was found in the samples. No PCB congener (detection limit = 2.0µg/L) was detected either. pp'DDE was found in 17 out of 33 samples in concentrations that ranged from 1.4 to 8.4 µg/L of serum or, on a fat basis, from 0.200 to 3.452 µg/g of serum lipids. Percentage of positive samples (%) and levels of pp'DDE (range of positive samples) increased from the youngest to the oldest group (<=29 yrs: 10%, 0.278µg/g; 30-39 yrs: 60%, 0.200-0.765µg/g; > or = 40 yrs: 77%, 0.257-3.452µg/g).

Na perspectiva da Psicologia Social (no enfoque, moscoviciano, da representação), foram investigados conceitos e imagens do cotidiano popidar na cidade do Rio de Janeiro, conforme se apresentam em cartilhas adotadas em escolas públicas. Procurou-se, então, notar a possível influência da literatura citico-social da alfabetização (acentuada desde o final dos anos 70) que, entre outras questões, discute a dissociação entre conhecimento (escolar) e realidade, enfatizando o princípio de aprendizagens significativas e contextualizadas. Nas análises, confrontaram-se as representações com "indicadores sociais" do cotidiano, levantados em estudos sociológicos. Os resultados demonstraram a predominância de conceitos e imagens de situações que, não só se distanciam, como invertem as que se apresentam nos "indicadores ". Desse modo, permanece a constatação de que o mundo das crianças não encontra significado no mundo das cartilhas. Abstract In the perspective of Social Psychology (in the Moscovite focal point of the representation), concepts and images of the popular quotidian in Rio de Janeiro city have been investigated, as they present themselves in the spelling books adopted in public schools. One endeavoured, then, to note the possible influence of the critical-social literature of the first year of schooling (accentuated since the end of the 70s), which, among other matters, discusses the dissociation between knowledge (scholar) and reality, enphasizing the principle of significative and contextualized apprendticeships. In the analysis, the representations confront themselves with "social indicators" of the quotidian, raised up in sociologie studies. The results demonstrated the predominance of concepts and images of situations which not only keep away from, as well as invert the ones which present themselves in the "indicators ". Thus, endures the evidence that the world of the children does not find significance in the world of the spelling books. Résumé Sous la perspective de la Psychologie Sociale, d 'après Moscovici (1978), ont été analises concepts et images du quotidien populaire dans la ville de Rio de Janeiro, selon ils se présentent dans les abécédaires adoptés dans les écoles publiques. Nous avons cherché, alors, observer la possible influence de la littérature critique-sociale (accentuée dès le final des années 70) sur l'alphabétisation. Cette littérature, parmi d 'autres questions, discute la dissociation entre savoir (scolaire) et réalité, en emphatisant le principe des apprentissages significatifs et contextualisés. Dans les analyses se confrontent les représentations avec les "indicateurs " sociaux du quotidien, relevés dans les études sociologiques. Les résultats ont démontré la prédominance des concepts et des images de situations que, non seulement s'éloignent comme inversent celles qui se présentent dans les "indicateurs". Ainsi, il nous reste la constatation que le monde des enfants ne recontre pas de signification dans le motide des abécédaires. Resumen En la perspectiva de la Psicoligia Social (en el enfoque moscoviciano de la representación), se investigaron conceptos y imágenes de lo cotidiano popular en la ciudad de Rio de Janeiro, según se presentan en cartillas adoptadas en escuelas públicas. Se procuró observar la posible influencia de la literatura crítico-social de la alfabetización, incrementada desde finales de los años setenta, que, entre otros temas, discute la disociación entre conocimiento (escolar) y realidad, enfatizando el principio de aprendizajes significativos y contextuados. En los análisis se confrontali las representaciones con "indicadores sociales" de lo cotidiano, obtenidos en estudios sociológicos. Los resultados han demostrado la predominancia de conceptos e imágenes de situaciones que no sólo se alejan, sino que invierten las presentadas en los "indicadores ". De esta manera, permanece la constatación de que el mundo de los niños no encuentra sifnificado en el mundo de las cartillas.
