Validation of the Portuguese Version of the Healthy Lifestyle Questionnaire

The main objective of this study was the validation of the Healthy Lifestyle Questionnaire (EVS II), using a confirmatory factorial analysis of the measurement model, with veteran athletes. A total of 348 veteran Portuguese athletes of both genders, aged between 30 and 60 years (M = 41.64, SD = 9.83), of whom 200 were males and 148 were females, from several sports. The results of the confirmatory factor analysis demonstrate the adequacy of the adapted version of the EVS II, as the factorial structure (6 factors/24 items) has acceptable validity indexes: χ2 = 305.925, p = 0.000, df = 120.017, χ2/df = 2.549, NFI (Normed Fit Index) = 0.909, TLI (Tucker Lewis Index) = 0.918, CFI (Comparative Fit Index) = 0.944, GFI (Goodness of Fit Index) = 0.944, AGFI (Adjusted Goodness of Fit Index) = 0.909, SRMR (Standardized Root Mean Square Residual) = 0.048, RMSEA (Root Mean Square of Approximation) = 0.060, allowing evaluation of the dimensions of balanced diet, respect for mealtime, tobacco and alcohol consumption, other drugs consumption and resting habits. The adaptation to sport of the Portuguese version of EVS II can be used with reasonable confidence in the evaluation of healthy lifestyles in the context of sportinfo:eu-repo/semantics/publishedVersio

Validity and Reliability of the Portuguese Version of the Healthy Lifestyle Questionnaire—EVS III

The main objective of this study was to validate the Healthy Lifestyle Questionnaire—EVS III, using confirmatory factor analysis of the measurement model. A total of 822 Portuguese individuals of both genders, aged between 18 and 66 years old (M = 28.43 SD = 12.07), participated in this study, of which 382 were male (46.5%) and 440 were female (53.5%). The main results obtained revealed that the psychometric qualities prove the adequacy of the factor structure of the Healthy Lifestyles Questionnaire—EVS III (7 factors/32 items) and that it has acceptable validity indices: χ2 = 644.6828, p = 0.000, df = 168, χ2 = 3.84, NFI = 0.901, TLI = 0.902, CFI = 0.921, IFI = 0.922, MFI = 0.900, GFI = 0.909, AGFI = 0.901, RMR = 0.073, SRMR = 0.059 and RMSEA = 0.059, enabling the assessment of factors related to a balanced diet, respect for mealtimes, tobacco consumption, alcohol consumption, consumption of other drugs, resting habits and physical activity habits. The Portuguese version of the Healthy Lifestyles Questionnaire—EVS III can be used with reasonable confidence for the assessment of healthy lifestyles.info:eu-repo/semantics/publishedVersio

Monitorización de las cargas de entrenamiento en corredores de fondo y medio fondo de alto nivel

El principal objetivo del entrenamiento consiste en mejorar el rendimiento y, por ende, reducir lesiones. Para ello, la monitorización de dicha carga (interna, externa y su relación) se ha constatado como vital. Sin embargo, muchos entrenadores siguen sin controlar (o etéreamente) las cargas en sus deportistas, pues, además, no existe un sistema etiquetado como el ideal. Consecuentemente, teniendo en cuenta el contexto y lo que la literatura dice al respecto, se realizó una propuesta personal con corredores de resistencia de alto nivel, contabilizando, en cuanto a carga externa, volumen mediante los kilómetros recorridos semanalmente, intensidad mediante la velocidad de carrera con zonas de entrenamiento en función del perfil individual de lactato, y frecuencia registrando el número de entrenamientos y de los contenidos trabajados. Respecto al estrés interno, la Escala de Esfuerzo Percibido y la medición de la altura del salto vertical con contramovimiento, en pos de determinar la fatiga neuromuscular subaguda. Los resultados mostraron relación significativa en la mayoría de variables, haciendo que el objetivo e hipótesis que perseguía la intervención se cumplan en mayor o menor medida, por lo que el sistema de monitorización escogido y/o los diferentes ítems que lo componen podrían ser válidos para su utilización en otros contextos.The main objective of training is to improve performance and, therefore, reduce injuries. For that reason, the monitoring of this load (internal, external and their relationship) has been verified as vital. However, many trainers still do not control (or ethereally) the loads on their athletes. In addition, there is not system labeled as the ideal. Consequently, taking into account the context and what the literature says about it, a personal research was made with high-level resistance runners, accounting, in terms of external load, volume through the kilometers traveled weekly, intensity through the running speed with training zones depending on the individual lactate profile, and frequency recording the number of training sessions and the contents worked. Regarding internal stress, the Rating of Perceived Exertion and a measurement of countermovement jump height, in order to determine subacute neuromuscular fatigue. The results showed a significant relationship in most variables, making the objective and hypothesis of the intervention have been met to a greater or lesser extent, so that the chosen monitoring system and / or the different items that comprise it could be valid for its use in other contexts.info:eu-repo/semantics/publishedVersio

Análisis del golpeo y la preparación psicológica para retornar a la práctica en futbolistas tras una lesión isquiosural

Las lesiones de la musculatura isquiosural son las más comunes en fútbol, y pueden presentar efectos residuales que cambien el patrón de un gesto técnico. El presente estudio analizó las diferencias en la técnica de golpeo entre jugadores anteriormente lesionados y jugadores no lesionados, así como las correlaciones entre la capacidad psicológica para retornar a la práctica y las características del gesto. Tres futbolistas que habían padecido una lesión de isquiosurales conformaron el grupo de jugadores anteriormente lesionados, y tres futbolistas que no habían padecido ninguna lesión en el miembro inferior en los últimos dos años, formaron el grupo de jugadores no lesionados. Se analizaron los gestos de golpeo a balón parado y de golpeo en carrera a través del programa Kinovea. Asimismo, se evaluó la capacidad psicológica para retornar a la práctica mediante el Injury Psychological Readiness to Return to Sport (I-PRRS). Únicamente la velocidad del balón en el golpeo en carrera presentó diferencias significativas entre grupos (p<0,05). Además, se obtuvieron correlaciones positivas entre la preparación psicológica para retornar y la flexión de rodilla en el golpeo en carrera, y entre la flexión de rodilla en el golpeo a balón parado y los ítems 3 y 4 del I-PRRS. Asimismo, se hallaron correlaciones negativas entre la extensión de cadera en el golpeo a balón parado y el ítem 6 del I-PRRS. Los resultados permiten concluir que variables cinemáticas y variables psicológicas se encuentran interrelacionadas tras una lesión en la musculatura isquiosural.info:eu-repo/semantics/publishedVersio

Predictive Model for Amotivation and Discipline in Physical Education Students Based on Teaching–Learning Styles

One of the purposes of teachers is to ensure the motivation of the students in their classes and to maintain disciplined behaviours. However, the teaching styles and methodologies used do not always have a positive effect on student’s motivation and discipline. This study analysed the relationship between student’s perceptions of the controlling behaviours of their physical education teacher, together with amotivation and discipline styles from Self-Determination Theory. The sample comprised 922 students, aged between 14 and 18 years (M = 14.95; SD = 0.98). Students’ perceptions of less controlling discipline styles (control of the use of rewards) negatively predicted the thwarting of autonomy need. Conversely, a more controlling discipline style (judging and devaluing) positively predicted the thwarting of autonomy need, and this, positively predicted amotivation, which nega- tively predicted disciplinary behaviours and positively predicted undisciplined behaviours. Teachers must avoid using controlling behaviours like judging and devaluing, as this reinforces amotivation towards physical education and undisciplined student behaviours. The importance of designing classes where the student has responsibilities to make decisions and to be part of their own learning is pointed out.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

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

Brain serotonin synthesis capacity in obsessive-compulsive disorder: effects of cognitive behavioral therapy and sertraline.

Cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs) are both effective treatments for some patients with obsessive-compulsive disorder (OCD), yet little is known about the neurochemical changes related to these treatment modalities. Here, we used positron emission tomography and the α-[11C]methyl-L-tryptophan tracer to examine the changes in brain regional serotonin synthesis capacity in OCD patients following treatment with CBT or SSRI treatment. Sixteen medication-free OCD patients were randomly assigned to 12 weeks of either CBT or sertraline treatment. Pre-to-post treatment changes in the α-[11C]methyl-L-tryptophan brain trapping constant, K* (ml/g/min), were assessed as a function of symptom response, and correlations with symptom improvement were examined. Responders/partial responders to treatment did not show significant changes in relative regional tracer uptake; rather, in responders/partial responders, 12 weeks of treatment led to serotonin synthesis capacity increases that were brain-wide. Irrespective of treatment modality, baseline serotonin synthesis capacity in the raphe nuclei correlated positively with clinical improvement. These observations suggest that, for some patients, successful remediation of OCD symptoms might be associated with greater serotonergic tone
