Influência da música preferida no desempenho e estados afetivos de idosos durante exercício de intensidade auto-selecionada

Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term

Indicadores de desempenho e percepção subjetiva de esforço entre técnico e atletas de voleibol

The present study has for objective been to know the answers of performance indicators between different positions of volleyball and check for possible relationship between subjective perception referred by coach effort of volleyball athletes during training. Eleven athlete of the feminine sex, during eight weeks, 23 carried through sessions of training and eleven games, inferior members (Vertical Jump) and superiors had been evaluated by means of measures of explosive power in (Throw Medicine Ball), at the beginning and end of each week. For the verification of the subjective perceived of exertion it was used scales proposal for Foster (1998), to the end of each session of training. The collected data had been kept in computer file, producing information in the descriptive plan (measured central and dispersion) and the inferencial for the analysis of variance for the model with a factor complemented with the test of multiple comparisons of Tukey and linear correlation of Pearson. The results present as it has detached: i) the exercises specifics as content of bigger frequency in the training; ii) the test of vertical jump presented difference between the positions and, finally, iii) the subjective perceived of exertion between coach and athlete, he points that the trainer overestimates in 9,76% the perceived of the athletes. Such data are argued how much to the contents of the training as well as the load used in the interior of the process of preparation and monitoring of the training.

Copépodes (Crustacea, Calanoida, Cyclopoida) planctônicos em reservatórios profundos e dendríticos: efeitos do tempo de residência e da idade de formação

Some ecological attributes of planktonic copepods (composition, diversity, abundance and its relations with limnological variables) were compared in two deep and dendritic reservoirs, 470km from each other, with contrasting water retention time (WRT) and ages of construction. Data were grouped from two different studies: samples were collected monthly between March/00 to February/01, on the Salto Caxias Reservoir (Iguaçu River), and tri-monthly between January/00 to October/01, on the Chavantes Reservoir (Paranapanema River). Eight species of Calanoida and six of Cyclopoida were identified in both reservoirs. The highest richness was observed in Salto Caxias (12 taxa) when compared with Chavantes (8 taxa), and six species were exclusive to Salto Caxias and two from Chavantes. Salto Caxias was studied one year after the construction, consequently with higher nutrients values in this period and showed generally high mean values of Copepoda (nauplius, copepodits and adults) than Chavantes, which is 38 years old. Some parameters as transparency, conductivity, turbidity and total nitrogen were significantly related with copepod abundance. New formation and sufficient long WRT could be an important cause for the highest richness of Calanoida and total abundance of individuals in Salto Caxias Reservoir.

Desenvolvimento da linguagem oral em crianças afastadas da família de origem

For a complete development of oral language it's necessary the development of genetic roots of thought and utterance postulates by Vygotsky, yet the meditation of adult and the influence social and cultural that is around the child. In cases of children moved away from their birth family by judicial ways because of neglect there, is a new modality of refuge in Brazil, that is the home refuge, which is the object of our research. The present study shows an investigation about the development of speech in a child that was moved away from his birth family and forwarded to Foster Family to comprehend the contributions and activities that help in child development. The research was performed through an approach of qualitative interpretation of bibliographic type and area type. The data analysis allowed us conclude the new social and cultural way that the watched child was inserted helps in his development in a significant way enabling a qualitative jump in speech and psychic functions phase

O uso da atividade guia (brincar) como catalisadora do desenvolvimento do pensamento e da linguagem

To select pedagogical practices that allow the development of psychic function thinking and psychic function language. It's necessary understanding the whole psyche human, postulated by Vygotsky. The action of playing, the main activity of the children in the childhood education, can enhance the resilience of the psychic functions, once it provides stimulus and may include teacher's intervention during its deployment. For a better intervention, this planning in light of a theory is primordial, as well as the reflection on this practice. This research aimed to find the moment of the activities that took place the development of these functions, language and thought, in children who are in the early years of the childhood education. The survey was conducted through a qualitative interpretation approach, as action research. Data analysis allowed us to observe planned teaching practices in which enabled the development of language and thought and consequently a qualitative leap in the other psychic functions

Co-occurrence of microcystin and microginin congeners in Brazilian strains of Microcystis sp.

Species of Microcystis are the most common bloom-forming cyanobacteria in several countries. Despite extensive studies regarding the production of bioactive cyanopeptides in this genus, there are limited data on isolated strains from Brazil. Three Microcystis sp. strains were isolated from the Salto Grande Reservoir (LTPNA01, 08 and 09) and investigated for the presence of mcy genes, microcystins and other cyanopeptides. Microcystin and microginin production was confirmed in two isolates using high-resolution tandem mass spectrometry after electrospray ionization (ESI-Q-TOF), and the structures of two new microginin congeners were proposed (MG756 Ahda-Val-Leu-Hty-Tyr and MG770 MeAhda-Val-Leu-Hty-Tyr). The biosynthesis profile of the identified cyanopeptides was evaluated at different growth phases via a newly developed HPLC-UV method. Results demonstrated no substantial differences in the production of microcystins and microginins after data normalization to cell quota, suggesting a constitutive biosynthesis. This study represents the first confirmed co-production of microginins and microcystins in Brazilian strains of Microcystis sp. and highlights the potential of Brazilian cyanobacteria as a source of natural compounds with pharmaceutical interest.

The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River

The composition and abundance of the fish assemblage were evaluated in the fish ladder of Ourinhos Dam, the newest dam (closed in 2005) in the cascade of dams constructed on the Paranapanema River. Samplings were carried out three times on a diel cycle, in three sampling periods, two in the warm season and one in the cold season of 2008 - 2009. The ladder was closed and emptied and the entire fish assemblage was sampled and identified. Most individuals were released alive downstream of the dam. The assemblage found in the ladder was compared with the fish fauna sampled in the reservoir and in downstream sites, in the same period. Twenty seven species and a total of 4682 individuals were caught in the ladder. Pimelodus maculatus was the only migratory species, which was caught in low number in the ladder (0.04% of the total captured), where small sedentary species predominated. The most abundant species were the non-migratory Apareiodon affinis, Bryconamericus stramineus, Astyanax fasciatus and Parodon nasus. Individuals observed in the ladder's window were moving up-and down the passage. The fish ladder is a microhabitat inhabited by an abundant association of benthic organisms that is probably used as a food resource for the fish assemblage in the ladder. The similarity between the fish fauna in the ladder and that of the Ourinhos Reservoir was low (26%). The species richness of migrants in the stretch between the uspstream reservoir (Chavantes) and the downstream one (Salto Grande), before the Ourinhos dam closure (23 species) was reduced to 16 and 12 species in Salto Grande and Ourinhos reservoirs, respectively, after the dam closure, and to a single species in the ladder.
