Transcontextual model application in the prediction of veteran judo athletes’ life satisfaction

Background and Study Aim: Despite recognised benefits of regular physical activity for health, the percentage of individuals linking with a physical activity practice sufficient to confer health benefits is low. The aim of current work is knowledge about effects of an extension of the motivation trans-contextual model application, specifically in the prediction of life satisfaction by veteran judo athletes. Material and Methods: It was used a sample of 99 Portuguese veteran judo athletes of both genders, aged between 30 and 76 years (M = 42.61 ±9.75), where through questionnaires were measured: basic psychological needs satisfaction, motivation, planned behaviour variables and life satisfaction. Results: The structural equations model showed that autonomy perception positively and significantly predicts autonomous motivation. In its turn it positively and significantly predicts intentions. Conclusions: Life satisfaction is positively and significantly predicted by intentions. Results authorise to emphasise the importance of fostering autonomy, since this will favour autonomous motivation, promoting a higher behavioural control over the practitioners’ intentions, thus generating a higher life satisfaction.info:eu-repo/semantics/publishedVersio

Application of two intervention programs in order to optimize motivation and to improve eating habits in adult and elderly women

The objective of this study was to analyse the effectiveness of two intervention programs: a physical exercise program with strategies to support the three basic psychological needs (autonomy, competence and relatedness); and a physical exercise program with nutritional education in order to improve the lifestyles of adult and elderly women who practiced functional maintenance. The Self-Determination Theory was applied as the theoretical framework. A sample of 135 women aged between 40 and 88 years (59.66 ± 10.76) who enrolled in a 12-week functional maintenance program and attended 24 exercise classes took part in the study. A quasi-experimental study was performed where strategies to support the three basic psychological needs were applied to one group and strategies for the improvement of eating habits were applied to the other group. No strategy was applied to the control group. The main results showed na improvement in experimental groups I and II when compared to the control group regarding the variables of autonomy, competence, intrinsic regulation, identified regulation, introjected regulation, external regulation and eating habits, after the application of the intervention programs. The conclusion is that both intervention programs were successful with this project's participants and that it is crucial to promote such intervention programs in functional maintenance classes, as they foster healthy lifestyles among participants.info:eu-repo/semantics/publishedVersio

Adaptation and validation of the portuguese version of the healthy life styles questionnaire

The aim of this study was the adaptation and validation of Healthy Lifestyle Questionnaire (EVS), of Jimenez Castuera (2004) adapted of Wold (1995), using an exploratory and confirmatory factor analysis of the measurement model, with a sample of sports veterans. In the exploratory and confirmatory factor analysis part 684 Portuguese veteran athletes of both genders, aged between 30 and 90 years (M=43.78 SD=8.61), of which 547 male subjects and 137 subjects were female, which are competitors of various sports. The main results showed that the psychometric qualities of both the exploratory factor analysis, and confirmatory factor analysis, proved the adequacy of adaptation performed, demonstrating that the factor structure (Adaptation to Sports Questionnaire EVS: 3 factors/20 items) It has quite acceptable levels of validity (?2 = 172.117, df=41, p = .000, ?2/g.l. = 4.190, CFI = .966, IFI = .966, MFI = .909, GFI = .955, AGFI = .927, RMR = .049, SRMR = .043, RMSEA = .068), with reasonable levels of internal consistency of the three primary factors (eating habits =.80; tobacco consumption =.91; resting habits =.84). This led us to conclude that the adaptation to the Sports of the Portuguese version of the EVS can be used with high confidence in the assessment of healthy lifestyles in the sports context.info:eu-repo/semantics/publishedVersio

Self-determined motivation and life satisfaction in portuguese veterans athletes

The aims of this work were to determine correlations and predictive variables, between the levels of motivation, basic psychological needs and life satisfaction of Portuguese veteran athletes. The sample consisted in 684 Portuguese veteran athletes of both genders, aged between 30 and 90 years (M = 43.78 DP = 8.61), competitors of various modalities. As instruments we used the Behavioral Regulation in Sport Questionnaire (BRSQ), the Basic Psychological Needs Scale Exercise (BPNES), the Satisfaction with Life Scale (SWLS) and Positives and Negatives Affections Scale (PANAS). It was applied the bivariate Pearson correlation test and multiple linear regression. The results showed that the veteran athletes present a good selfdetermination for the sport practice, being their welfare levels in life satisfaction related to the same self-determination, but rather dependent on the affections produced by sports. This study is presented as a contribution to understanding the role of sport in promoting wellness in veteran sports population.El objetivo de este estudio fue determinar las correlaciones y variables predictivas entre los niveles de motivación, las necesidades psicológicas básicas y la satisfacción con la vida de atletas veteranos portugueses. La muestra se compuso de 684 atletas veteranos portugueses de ambos géneros, con edades comprendidas entre los 30 y los 90 años (M = 43.78; DP = 8.61),, competidores de varias modalidades. Los instrumentos utilizados fueran el Cuestionario de la Regulación Conductual en el Deporte (BRSQ), la Escala de Satisfacción de Necesidades Psicológicas Básicas (BPNES), la Escala de Satisfacción con la Vida (SWLS) y la Escala de Afectos Positivos y Negativos (PANAS). Se aplicó la prueba de correlación bivariada de Pearson y una regresión lineal múltiple.Los resultados mostraron una motivación autodeterminada de los atletas veteranos hacia la práctica deportiva, estando sus niveles de bienestar en la satisfacción con la vida relacionados con esta motivación autodeterminada, aunque también depende de los afectos producidos por la práctica deportiva. Este estudio supone una contribución hacia la comprensión de la función del deporte en la promoción del bienestar en la población de deportistas veteranos.info:eu-repo/semantics/publishedVersio

In vitro inhibition of Phytophthora capsici, Fusarium oxisporum and Verticillium dalhiae by native plant growth promotion rhizobacteria strains from Mendoza

The rapid growth of the human population and their need of food has impulse to extensive use of chemical fertilizers and pesticides to increase yield crop. These practices are costs and increase environmental pollution. In the last years, appear needs for novel agricultural practices that do not harm natural ecosystems. Different plant growth promotion Rhizobacteria (PGPR) have been studied and incorporated into agricultural practices and biocontrol has emerged in recent years as an alternative to pesticides. PGPR antagonize orprevent the effects of phytopathogens or deleterious microorganisms. PGPR produce substances that protect them against variousdiseases. Metabolites include hydrogen cyanide and antibiotics. Some strain PGPRs produce lytic enzymes as β-1,3-glucanase,chitinase, protease and cellulase that degrade the cell wall of fungi and produce a direct inhibitory effect on the growth of hyphae.Another important mechanism of biocontrol of PGPRs is related to the production of siderophores that chelate iron, making itunavailable to pathogens. In this study four native PGPR strains of Mendoza against pathogenic fungi of pepper crops were evaluated.The test was carried out by fourfold and repeated two times using independent Petri dishes for the growth of each bacterial strain andeach pathogens. On Luria Broth (LB) and potato dextrose agar (PDA) plates, one disc of a 5 mm plug carrying mycelia fungi (P.capsici, F. oxisporum or V. dalhiae) previously grown for 3 days in PDA was placed and each individual bacterium (60I1, 53F, 64S1,42P4) was plated as line. Bacterial strains were cultivated in LB medium for 24 h at 30 °C with orbital shaking (120 rpm). The bacterialcultures were adjusted to a final concentration of 108cells mL−1. The assay was performed incubated at 30 °C for 7 days. The myceliumgrowth was digitally determined every day. A control plate was included growing with the fungi. The percentage of inhibition was calculated comparing to the control. The strains 53F, 64S1 y 42P4 inhibited F. oxisporum and V. dalhiae in vitro mycelium growth.The 42P4 strain inhibited the P. capsici growth in APG plates. Also, we observed the production pyoverdine by 42P4 strain under UV in APG medium.Fil: Lobato Ureche, Miguel Andres. Consejo Nacional de Investigaciones Científicas y Técnicas.

Trabalho em ambientes refrigerados: estudo de caso com a realização de monitorização ambiental e electrocardiográfica

Introdução - Em ambientes laborais de baixa temperatura ocorrem reacções fisiológicas destinadas a ajustar o equilíbrio térmico que podem conduzir a sobrecarga cardiovascular. Contudo, em várias áreas de actividade o frio é um factor essencial para a produção, o que torna a exposição ocupacional uma realidade incontornável. Este estudo teve como objectivo identificar alterações electrocardiográficas em trabalhadores de uma Indústria de Processamento de Carnes (IPC), em condições laborais de baixa temperatura (<8ºC) e caracterizar o ambiente térmico. Metodologia - Foram medidos por equipamento específico os parâmetros ambientais (temperatura, humidade relativa e velocidade do ar). Foram calculados o índice IREQ (isolamento requerido pelo vestuário) e o nível de actividade metabólica por posto de trabalho. A monitorização electrocardiográfica foi efectuada através de electrocardiografia ambulatória de Holter (EcgAH). Para recolha de dados complementares ao EcgAH, foram também utilizados um diário de EcgAH, um questionário e um termómetro digital. Resultados/Discussão - A amostra em estudo estava sujeita a um grau hipotérmico ligeiro, podendo dever-se à ausência de exposição a stress térmico e à confluência de factores como: a elevada percentagem de trabalhadores que utiliza vestuário adicional além do protector cedido pela IPC e a elevada taxa metabólica inferida pela análise da frequência cardíaca. Os resultados deste estudo divergiram dos da literatura consultada, não se identificando qualquer expressão electrocardiográfica comum na hipotermia. Considerações finais - Sugere-se a implementação de algumas medidas de carácter organizacional uma vez que, por questões produtivas, é impossível alterar as condições térmicas. Apesar de não se terem identificado alterações electrocardiográficas, considera-se pertinente integrar exames do foro cardiovascular (para além do electrocardiograma, também o electrocardiograma ambulatório de Holter, a medição ambulatória da pressão arterial e ecocardiograma) nos exames realizados no âmbito da medicina do trabalho, pois ambientes refrigerados podem promover alterações a nível cardíaco

Validación del cuestionario de estilo de vida saludable (evs) en una población española

Para evaluar el estilo de vida de las personas es importante el desarrollo de un cuestionario que se pueda aplicar a cualquier población. El objetivo principal fue adaptar y validar al contexto español el cuestionario de Estilos de Vida Saludables (EVS), y posteriormente dotar al cuestionario de validez concurrente por medio de un análisis de correlación con las variables de los niveles de motivación autodeterminada hacia la práctica deportiva. La muestra total del estudio estuvo compuesta por 812 personas entre los 14 y los 88 años (29.5±21.7). Cinco ítems evaluaron cada uno de los factores relacionados con un EVS: consumo de tabaco, hábitos de descanso, respeto al horario de las comidas, y mantener una alimentación equilibrada. Los resultados globales del modelo indicaron un ajuste óptimo, así como una buena validez concurrente. Este estudio ha proporcionado una escala válida y fiable para evaluar el estilo de vida saludable de la población española. Esta escala se considera de gran utilidad para su aplicación en diferentes centros, tanto escolares como deportivos, para, una vez aplicados, orientar a la población hacia un estilo de vida saludable.info:eu-repo/semantics/publishedVersio

Relationship between motivational variables and pre-competitive anxiety in handball players

Los deportistas, cuando se están preparando para la competición, a veces tienen que enfrentarse a muchas tensiones, por lo tanto, el ob- jetivo de nuestra investigación fue analizar la relación entre los tipos de motivación, necesidades psicológicas básicas y el ansiedad precom- petitiva en jugadores de balonmano. Los instrumentos utilizados fueron: el Cuestionario de Evaluación del Regulación de Conducta en Contexto del Ejercicio (BREQ-3), la Escala de Satisfacción de Necesidades Psicológicas Básicas (PNSE) y la Escala de Ansiedad CSAI-2R. La muestra consistió en 45 jugadores de balonmano, todos de sexo masculino (M= 23.16; DT= 7.05). Los resultados muestran que la mo- tivación autónoma se relaciona positiva y significativamente con la motivación controlada, podemos ver que la motivación controlada se relaciona positiva y significativamente con la desmotivación y que la desmotivación no está relacionada de manera positiva y significativa con ninguna variable de este estudio, sin embargo, se relaciona nega- 89 Abordagens Académicas de Investigação 90 tivamente y de forma significativa con la necesidad psicológica básica de competición, con la ansiedad precompetitiva somática y cognitivo en función de su dirección. Algunas de las limitaciones que se encon- traron fueran: no encontrar una muestra de mujeres, la mayoría de los jugadores que deseen participar eran clase base y la edad de los participantes.When competing, the players are exposed to many pressures. Thus, the objective of our research was to analyse the relationships between the motivation types, the basic psychological needs and the pre-com- petitive anxiety of the athlete in handball players. In order to do so, we used the Behavioural Regulation in Exercise Questionnaire (BREQ-3), the Basic Psychological Needs in Exercise Scale (PNSE) and the Compe- titive State Anxiety Inventory (CSAI-2R). The sample was composed by 45 handball players, all male (M: 23.16; DT: 7.05). Results have shown that the self motivation is positively and significantly related to the controlled motivation, which we can observe to be positively ans sig- nificantly related with poor motivation, which is not positively nor sig- nificantly related to any variable of this study, however, it is negatively and significantly related to the competition basic psychological need, with the somatic and cognitive pre-competitive anxiety according to its direction. Some of the limitations we encountered were: not finding a female sample, most of the players willing to participate were of a basic category and, therefore, the age of these participants.info:eu-repo/semantics/publishedVersio

Differences between high performance and base handball players in motivational variables and pre-competitive anxiety.

Los deportistas, cuando se están preparando para la competición, a veces tienen que enfrentarse a diferentes tensiones que pueden pro- vocar que el deportista no sea capaz de alcanzar las metas que se ha fijado. Por lo tanto, nuestro objetivo fue determinar las diferencias en- tre jugadores de balonmano de alto rendimiento y categorías de base, en función de los tipos de motivación, las necesidades psicológicas bá- sicas y de ansiedad precompetitiva. Para ello, contamos con una muestra de 45 atletas de diferentes cate- gorías y edades comprendidas entre 14 y 37 años (M= 23.16, DT= 7.5). Los instrumentos utilizados fueron: el Cuestionario de Evaluación del Regulación de Conducta en Contexto del Ejercicio (BREQ-3), la Escala de Satisfacción de Necesidades Psicológicas Básicas (PNSE) y la Escala de Ansiedad CSAI-2R. Los resultados muestran que los atletas de clase de base muestran una mayor desmotivación y la necesidad psicológica básica para la competición es mayor en los atletas de alto rendimiento. Se obser- Abordagens Académicas de Investigação 56 vó que en la variable autoconfianza es menor en los atletas de clase base, la variable ansiedad somática y variable de ansiedad cognitiva son menores en los atletas de clase base que en los atletas de alto ren- dimiento. Por lo tanto, como máximas de trabajo, hay que aumentar la autoconfianza y la motivación autónoma y disminuir la ansiedad.When preparing for competition, sometimes the players have to face different pressures which may cause the athlete not to be able to achieve the goals established. Thus, our objective was to determine the differences between high performance and base handball players regarding the motivation types, the basic psychological needs and the pre-competitive anxiety. In order to do so, we had a sample of 45 players from different categories from 14 to 37 years old (M: 23.16, DT: 7.5). The instruments used were: the Behavioural Regulation in Exer- cise Questionnaire (BREQ-3), the Basic Psychological Needs in Exercise Scale (PNSE) and the Competitive State Anxiety Inventory (CSAI-2R). Results show that the base category players evidence poorer moti- vation, the basic psychological need is greater in high performance athletes, we observed the self-confidence variable to be inferior in base category athletes, the somatic anxiety variable and the cogniti- ve anxiety variable are inferior in base category athletes than in high performance athletes. Therefore, we should work towards the goal of increasing self-confidence and self-motivation and to decrease anxiety.info:eu-repo/semantics/publishedVersio

Diferenças em função do género do comportamento planeado para a prática desportiva, estilos de vida saudáveis e satisfação com a vida de atletas veteranos

The aim was to analyze gender differences of planned behavior for sports practice, healthy lifestyles and satisfaction with the lives of veteran athletes. The sample consisted of 320 Portuguese veterans of both sexes, aged between 30-60 years (M = 44 SD = 8.6), competitors of various modalities. The Measurement Questionnaire for Planned Behavior, the Life Satisfaction Questionnaire and the Healthy Lifestyle Questionnaire were used as instruments of measurement. Data revealed that veteran Portuguese athletes differ in planned behavior when compared between genders. Female athletes revealed significantly higher levels of satisfaction with life and healthy eating habits as well as rest when compared to male athletes, cognitive and behavioral indicators of superior well-being by the action of sports. This study contributes to the understanding of the role of sport in promoting well-being in the veteran population, and it is of interest to foster the perception of behavioral control in both genders as a way of strengthening intentions and consequently maintenance in adherence to sports practice.O objetivo foi analisar as diferenças em função do género do comportamento planeado para a prática desportiva, estilos de vida saudáveis e satisfação com a vida de atletas veteranos.
