- Basic psychological needs and subjective well-being in Portuguese older peoplePublication . Couto, Nuno; Antunes, Raul; Monteiro, Diogo; Moutão, João; Marinho, Daniel A.; Cid, LuísThe aim of this study is the validation of the Portuguese version of the Basic Need Satisfaction General Scale (BNSG-S) in a sample of Portuguese elderly, and analyze through a structural equations model the effect of the Portuguese elderly individuals’ global perception about the satisfaction of basic psychological needs on subjective well-being. Two samples of Portuguese elderly people aged between 60 and 90 years old were considered in this study. Results revealed that they Model 3 of the BNSG-S (three factors, 11 items) adjusted to the data a (Χ2 = 103.16, df = 41, SRMR =. 05, TLI =. 90, CFI =. 93, RMSEA =. 07, 90% CI =. 05-.08). Additionally, structural model analysis, showed a positive and significant effect between satisfaction of basic psychological needs and subjective well-being. In sum we concluded that the Portuguese version of the BNSG-S can be used as a means to evaluate the satisfaction of the basic psychological needs of the older population and, their satisfaction, has a positive effect on subjective well-being in the Portuguese older population.
- Conceptual Framework for the Research on Quality of LifePublication . Rodrigues, José; Borrego, Carla Chicau; Ruivo, Paula; Sobreiro, Pedro; Catela, David; Amendoeira, José; Matos, RuiThe article presents the reference framework for multidisciplinary research at the Life Quality Research Centre (LQRC). The research paradigm about the citizens' quality of life in society imposes a multifaceted and complex analysis. At the LQRC we address this as thematically divided into six scientific areas: education and training; physical activity and healthy lifestyles; food production and technology on food behaviors; organizational dynamics; motor behavior; and individual and community health. These areas are clearly related to the concept of quality of life. They fit the goals and dynamics of the research center. In each section, the authors develop the themes of research projects and the challenges that characterize research in the area of quality of life. It is clear that there is an agreement and understanding that ensures that quality of life research is on the agenda of the world organizations related to scientific research and human development. This is a real challenge for scientific research centers, since multidisciplinary paradigms are the foundation of our collective organization, and the evolution of research on quality of life could fulfil current needs and lead to the improvement of citizen lives.
- Estimation of an Elite Road Cyclist Performance in Different Positions Based on Numerical Simulations and Analytical ProceduresPublication . Forte, Pedro; Marinho, Daniel A.; Barbosa, Tiago M.; Morouço, Pedro; Morais, Jorge E.The aim of this study was to use numerical simulations and analytical procedures to compare a cyclist's performance in three different cycling positions. An elite level road cyclist competing at a national level was recruited for this research. The bicycle was 7 kg and the cyclist 55 kg. A 3D scan was taken of the subject on the competition bicycle, wearing race gear and helmet in the upright position, in the handlebar drops (dropped position) and leaning on the elbows (elbows position). Numerical simulations by computer fluid dynamics in Fluent CFD code assessed the coefficient of drag at 11.11 m/s. Following that, a set of assumptions were employed to assess cycling performance from 1 to 22 m/s. Drag values ranged between 0.16 and 99.51 N across the different speeds and positions. The cyclist mechanical power in the elbows position differed from the upright position between 0 and 23% and from the dropped position from 0 to 21%. The cyclist's energy cost in the upright position differed 2 to 16% in comparison to the elbows position and the elbows position had less 2 to 14% energy cost in comparison to the dropped position. The estimated time of arrival was computed for a 220,000 m distance and it varied between 7,715.03 s (2 h:8 min:24 s) and 220,000 s (61 h:6 min:40 s) across the different speeds and positions. In the elbows position, is expected that a cyclist may improve the winning time up to 23% in comparison to he upright and dropped position across the studied speeds.
- Physical activity and affect of the elderly: Contribution to the validation of the Positive and Negative Affect Shedule (PANAS) in the Portuguese populationPublication . Antunes, Raul; Couto, Nuno; Vitorino, Anabela; Monteiro, Diogo; Marinho, Daniel A.; Cid, LuísThe concept of affect corresponds to the emotional dimension of subjective well-being (Diener, Emmons, Larsen, & Griffin, 1985). It is represented by two dimensions (negative affect and positive affect), which were the basis of the development of the Positive and Negative Affect Schedule - PANAS (Watson, Clark, & Tellegen, 1988). It was translated and validated for the Portuguese population by Galinha and Pais-Ribeiro (2005b). Nevertheless, because the Portuguese version was not validated in a sample of Portuguese elderly, the goals of this study consisted in the translation of the scale (PANAS) from the original version of 20 items and the validation of its measurement model (including a shortened version) for a sample of Portuguese elderly (n = 311), aged 60 years or older (M = 68.53; DP = 6.69); it was then tested by a confirmatory factorial analysis. The results demonstrated that the measurement model (two factors and 10 items) of the shortened Portuguese version of the PANAS presented acceptable psychometric qualities, which adjusted to the data in a satisfactory way (factorial weights ranging between .57 and .70 in positive affect and between .52 and .68 in negative affect). We also concluded that older adults who practice more physical activity perceive higher levels of positive affect F(2, 297) = 3,78, p < .05; η2 = .025, and lower levels of negative affect F (2, 297) = 6.24, p < .001; η2 = .040).
- The relationship between coaches’ interpersonal behaviors, basic psychological needs, behavioral regulation, and intentions towards sport persistencePublication . Monteiro, Diogo; Teixeira, Diogo S.; Morales-Sanchéz, Veronica; Chica-Merino, Encarnación; Matos, Rui; Amaro, Nuno; Antunes, Raul; Jacinto, MiguelThis study investigates the relationships between coaches’ need-supportive and need-thwarting behaviors, satisfaction of basic psychological needs, motivation, intentions to continue, and athletes sport persistence. A total of 518 athletes (212 male, 306 female), 18 to 32 years (M = 23.18, SD = 4.19), participated in the study, with participants from football (n = 179), basketball (n = 166), and swimming (n = 173). A structural equation model and a mediation model were performed to understand the associations between motivational factors based on self-determination theory and a 2-year sport persistence assessment. Intentions to continue sport practice accounted for 12% of the variance related to sport persistence in the structural equation model. The mediation model did not reveal any direct effects for need-supportive or need-thwarting behaviors towards sport persistence. However, significant indirect paths were identified in the bright side of the model. Total indirect effect of the need-supportive behaviors in the model was β = .14 (CI95% = .26, .37) while for need-thwarting behaviors was β = −.05 (CI95% = −.11, −.01) towards sport persistence, indicating a positive mediation process. Coaches by being perceived as need-supportive may increase athletes’ intention to continue participating in sport, and consequently sport persistence.
- Relationship Between Mental Health and the Education Level in Elderly People: Mediation of Leisure AttitudePublication . Belo, Pedro; Navarro-Pardo, Esperanza; Pocinho, Ricardo; Carrana, Pedro; Margarido, CristóvãoPurpose: The present study intends to explore the influence of education on the mental health of retired people and the mediating role of a leisure attitude in this relationship. Design/Methodology: The sample was simple random, and a confidentiality agreement was established. The sample was composed of 403 Portuguese participants (37.2% male; 62.8% female). The participants completed the MHI and the LAS. Findings: The hypothesized mediation model showed that a leisure attitude mediated the association between education and well-being. In addition, higher levels of distress were found in participants with higher levels of education. Scientific Contribution: Our results suggest that old-aged people with high education and a more positive leisure attitude have a better psychological adjustment concerning well-being. Also, a higher level of education can lead to a better perception of aging changes (physical, life, profession).
- Significant bivariate correlations: to be or not to be?Publication . Morouço, PedroJust like in many other fields of research, sport sciences use statistics to infer about the associations between variables. For example, aiming to examine the relationship between squat jump with sprint running velocity has brought several experiments, demonstrating a strong to very strong association between variables (e.g., Sleivert & Taingahue, 2004; Wisløff et al., 2004). From there on, there have been researchers proposing training programs for improving the squat jump, and consequently, the sprint running (e.g., Chelly et al., 2009). While this example seems unanimous, other emerging ideas may be questionable.
