    Analysis of mediation and reciprocal effects of changes in weight, self-esteem, and exercise in a behavioral weight loss treatment
    (2008) Palmeira, António Labisa; Teixeira, Pedro J.; Silva, Marlene N.; Markland, David; Branco, Teresa; Martins, Sandra; Minderico, C. S.; Serpa, Sidónio O.; Sardinha, Luís B.; Faculdade de Educação Física e Desporto
    Improving the treatment of obesity remains a critical challenge. Several health behaviour change models, often based on a social-cognitive framework, have been used to design weight management interventions (Baranowski et al., 2003). However, most interventions have only produced modest weight reductions (Wadden et al., 2002) and socialcognitive variables have shown limited power to predict weight outcomes (Palmeira et al., 2007). Other predictors, and possibl alte nati e e planatory models, are needed to better understand the mechanisms by which weight loss and other obesity treatment-outcomes are brought about (Baranowski, 2006). Self-esteem is one of these possible mechanisms, because is commonly reported to change during the treatment, although these changes are not necessarily associated with weight loss (Blaine et al., 2007; Maciejewski et al., 2005). This possibility should be more evident if the program integrates regular exercise, as it promotes improvements in subjective well-being (Biddle & Mutrie, 2001), with possible influences on long-term behavioral adherence (e.g. diet, exercise). Following the reciprocal effects model tenets (Marsh & Craven, 2006), we expect that the influences between changes in weight, selfesteem and exercise to be reciprocal and might present one of the mechanisms by which obesity treatments can be improved.

    Ball Recovery in the Handball Tournament of the 2008 Beijing Olympic Games: Sequential Analysis of Positional Play as Used by the Spanish Team’s Defence
    (ACM New York, NY, USA, 2010) Lopes, António; Camerino, Oleguer; Anguera, Maria Teresa; Jonsson, Gudberg K.; Faculdade de Educação Física e Desporto
    In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.

    Characterization and Evaluation of young ring hockey team
    (Universidade Lusófona de Humanidades e Tecnologias, 2008) Madeira, Raquel Maria Santos Barreto Sajara; Faculdade de Educação Física e Desporto
    Ring hockey is a complex team sport with physical tecnical and tactical high demans (Manaças, 1988; Rodriguez, 1991). In teh absence of a battery of specific tests we proceed to the aplication of the 20 meters shuttle run test (Luc Leger, 1982) in youthfuk athletes of the juveniles.

    Confirmatory Factor Analysis of the Behavioural Regulation in Exercise Questionnaire – Portuguese Version
    (2007) Palmeira, António Labisa; Teixeira, P.; Silva, M. N.; Markland, David; Faculdade de Educação Física e Desporto
    Exercise constitutes one of the pillars of a healthy lifestyle (USDHHS, 1996). Paradoxically, more than 40% of Europeans are sedentary (Eurobarometer 213, 2004), although some interventions, at both community and individual levels, have been established to improve this situation. Some of these interventions are based on Self-Determination Theory (SDT: Deci & Ryan, 1985), which state that more internalized types of behaviour regulation lead to feelings of selfdetermination in one’s chosen activities and, consequently, to greater likelihood of behavioural adherence. Today, SDT is one of the most popular approaches to the study of exercise, thus the cross-cultural validation of instruments that can measure its constructs is a necessary step to further advance in the study of exercise motivation.

    Predictors of Successful Weight Control: Cross-Cultural Moderators of Treatment Outcomes
    (2007) Sardinha, Luís B.; Teixeira, Pedro J.; Going, Scott B.; Tomás, Rita; Carraça, Eliana Cristina Veiga, orient.; Silva, Marlene N.; Palmeira, António Labisa; Lohman, Timothy G.; Faculdade de Educação Física e Desporto
    Given the heterogeneity of effect sizes within the population for any treatment, identifying moderators of outcomes is critical [1]. In weight management programs, there is a high individual variability in terms of weight loss and an overall modest success [2]. Some people will adopt and sustain attitudes and behaviors associated with weight loss, while others won’t [3]. To predict weight loss outcome just from the subject’s baseline information would be very valuable [4,5]. It would allow to: - Better match between treatments and individuals - Identify the participants with less probability of success (or potential dropouts) in a given treatment and direct them to alternative therapies - Target limited resources to those most likely to succeed - Increase cost-effectiveness and improve success rates of the programs Few studies have been dedicated to describe baseline predictors of treatment success. The Healthy Weight for Life (USA) study is one of the few. Its findings are now being cross-validated in Portuguese samples. This paper describes these cross-cultural comparisons.

    Preliminary Validation of the Portuguese Version of the Eating Inventory for Athletes
    (2008) Palmeira, António Labisa; Veloso, S.; Falcão, M. J.; Dosil, J.; Faculdade de Educação Física e Desporto
    The field of eating disorders among athletes has recently been Preliminary Validation of the Portuguese Version of the Eating Inventory for Athletes Palmeira, A.L.(1); Veloso, S.(1); Falcão, M.J.(1); and Dosil, J.(2) Table 2. Exploratory Factor Analysis and Cronbach’s Alpha the focus of several publications, reflecting a growing field of interest and research (Dosil, 2008). Some sports demand a strict compliance to restrictive diets at different times of the competitive season, while others like, some types of gymnastics emphasize the thinness of the athletes. Hence there is a need to develop sound measures to evaluate the athletes eating habits and possible eating disorders. The Cuestionario de Hábitos Alimentarios del Deportista (CHAD), is one of these measures. It comprises 5 dimensions: i) Weight Gain Anxiety (e.g. If I eat too much I regret it afterwards; 12 items); ii) Body Image Worries (e.g., I’m always thinking about my body; 6 items,); iii) Irritability (e.g., If the coach speaks about weight matters, I feel anxious; 7 items); iv) Satisfaction/Dissatisfaction with Body Image (e.g., I’m satisfied with my appearance; 5 items); and v) Dieting (e.g., When the season ends, I keep practicing so that I don’t gain weight, 4 items).

    Relationship between antropometric, corporal composition and performance in young swimmers, boys and girls
    (Edições Universitárias Lusófonas, 2008) Madeira, Raquel Maria Santos Barreto Sajara; Conceição, Ana Teresa; Faculdade de Educação Física e Desporto
    The young athlete is physiologically unique from the adult and must be considered differently. The growth and development of their bones, muscles, nerves, and organs largely dictate their physiological and performance capacities (Bar–Or, 1983; Costill & Wilmore, 1994; Stager et al., 2008). Swimming performance, and the required times to reach a competition (TAC), shoud look for those diferences and should be compatibles with them.
