Objectives: Many athletes struggle in managing the end of their career, often gaining weight and adopting unhealthy lifestyles. Lifestyle programmes targeting former athletes who have gained substantial fat mass (FM) postsports career are lacking. We studied the effects of the Champ4Life programme on body composition and other health-related outcomes in former elite athletes with overweight or obesity.Methods: Ninety-four former athletes(42.4±7.3 y, 34.0% female) were recruited and randomly assigned to either an intervention group (IG; n=49) or a control group (CG; n=45). The IG attended 12 educational sessions addressing physical activity, weight management and nutrition. They also had a nutrition appointment aimed to prescribe a moderate caloric deficit(~300-500 kcal/day). Dual-energy X-ray absorptiometry was used to assess body composition. The Short-Form Health Survey-36 questionnaire was used to measure general health-related quality of life. Blood samples were collected to assess cardiometabolic health parameters.Results: At 12 months, the IG lost more weight (estimated difference (ED)=-5.3 kg; -6.9 to -3.8), total FM (ED=-4.1 kg; -5.4 to -2.8) and abdominal FM (ED=-0.49 kg; -0.64 to -0.33) than did the CG (p's<0.001). Cardiometabolic health markers also improved significantly (p<0.05) more in the IG at 12 months (insulin (ED=-4.9 μU/mL;-8.0 to -1.8); homoeostatic model assessment (ED=-1.2; -2.1 to -0.4); total cholesterol (ED=-21.8 mg/dL; -35.4 to -8.2); low-density lipoprotein (ED=18.2 mg/dL;-29.2 to -7.1)), as did quality-of-life dimensions (physical functioning (ED=11.7; 6.5 to 16.9); physical role (ED=17.6; 2.1 to 33.0); general health (ED=19.4; 11.4 to 27.4); vitality (ED=13.3; 5.3 to 21.3) and mental health (ED=12.3; 4.1 to 20.6)).Conclusions: The Champ4Life programme was effective in substantially reducing total and abdominal FM while preserving fat-free mass and improving health-related markers. These findings will enable evidence-based decisions when implementing lifestyle interventions targeting retired elite athletes.Trial Registeration Number: NCT03031951.

Background: Sleep, sedentary behaviour and physical activity are constituent parts of a 24h period and there are several questionnaires to measure these movement behaviours, the objective was to systematically review the literature on content and measurement properties of self- and proxy-reported questionnaires measuring movement behaviours in adults and older adults. Methods: The databases PubMed, CINAHL, PsycINFO and SPORTDiscus were systematically searched until April 2021. Articles were included if: the questionnaires were design for adults and older adults; the sample size for validity studies had at least 50 participants; at least, both validity and test-retest reliability results of questionnaire that were developed specifically to measure the amount of sleep, sedentary behaviour or physical activity, or their combination were reported; and articles had to be written in English, Spanish, French, Portuguese, German, Italian or Chinese. Findings and conclusions: Data extraction, results, studies' quality, and risk of bias were evaluated using the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. Fifty-five articles were included in this review, describing 60 questionnaires. None of the questionnaires showed adequate criterion validity and adequate reliability, simultaneously; 68.3% showed adequate content validity. The risk of bias for criterion validity and reliability were very low in 72.2% and 23.6% of the studies, respectively. Existing questionnaires have insufficient measurement properties and frequent methodologic limitations, and none was developed considering the 24h movement behaviour paradigm. The lack of valid and reliable questionnaires assessing 24h movement behaviours in an integrated way, precludes accurate monitoring and surveillance systems of 24h movement behaviours.

Doutoramento em Motricidade Humana, especialidade em Saúde e Condição Física The present Thesis was set within a longitudinal randomized controlled trial, consisting of a 1-year theory-based behavior change intervention and a 2-year follow-up period with no intervention. This trial included 239 overweight or obese women (age: 37.6±7 y; BMI: 31.5±4.1 kg/m2) who were premenopausal and free from identified disease. The main intervention was designed to increase physical activity and internal motivation, following self-determination theory (SDT). While tested before for other health behaviors with promising results, SDT had never been previously applied to weight management in longterm, controlled designs. Thus, the four studies comprising this Thesis were designed to provide a comprehensive analysis of how a theory-based intervention, implemented to affect specific theory-based mediators, would impact exercise adherence and body weight change both in short and long-term, from a SDT perspective. After a complete description of the study protocol, theoretical framework, and main intervention strategies (study 1), study 2 showed that the intervention was successful in affecting theory-driven mediators, physical activity, and weight change at 12 months (intervention’s end), demonstrating that the socio-contextual characteristics advanced by SDT Abstract -2- are amenable to manipulation, and revealing the potential utility of SDT to shape behavioral interventions targeting the promotion of physically active lifestyles and weight-change. Studies 3 and 4 searched for a more in-depth understanding of the dynamics of exercise motivation by exploring and testing mediational models aimed at outlining theory-based mechanisms and their impact on different types of physical activity at intervention’s end (study 3), and on long-term behavioral exercise regulations and physical activity (24-month) and 36-month weight change (study 4). Convergent with previous research, but extending it into the context of a randomized controlled trial, these studies indicated that perceived needsupportive health care climate, psychological needs for autonomy and competence, and intrinsic motivation mediate the effects of the experimental treatment climate on structured exercise behavior. Furthermore, these variables rested within the causal path of long-term weight loss, providing evidence from a link between experimentally-increased autonomous motivation, long-term physical activity adoption, and 3-year weight management. This application of SDT to physical activity and weight management provides experimental evidence that an autonomy-supportive context facilitates the internalization of regulatory processes, particularly through its effect on exercise-related constructs, which in turn promote long-term positive behavioral and clinical outcomes in overweight/obese women. A presente tese foi desenvolvida no contexto de um estudo longitudinal, controlado e com distribuição aleatória, configurando uma intervenção comportamental teoricamente sustentada, com a duração de um ano, seguida de dois anos de follow-up (sem qualquer intervenção). Este estudo envolveu 239 mulheres com excesso de peso ou obesidade, prémenopausicas e sem patologia diagnosticada. O programa de intervenção foi desenhado de acordo com os princípios base da teoria da auto-determinação (TAD), visando sobretudo o aumento da motivação intrínseca para a actividade física, procurando-se promover a sua adesão a longo prazo. Apesar de este enquadramento conceptual já ter sido testado com resultados promissores na promoção de vários comportamentos de saúde, não há relato de um teste experimental, com avaliações no longo prazo, da TAD no âmbito do controlo do peso. Os 4 artigos que constituem esta tese, no seu conjunto, foram desenhados para permitir a análise do modo como uma intervenção teoricamente sustentada, desenhada e implementada para ter efeito em variáveis-alvo mediadoras poderá influenciar a adesão ao exercício e a alteração do peso corporal, tanto no curto como no longo prazo. Partindo de uma descrição pormenorizada do protocolo experimental, das principais estratégias de intervenção e do racional teórico que as sustenta (estudo 1), o estudo 2 veio demonstrar que, 1 ano após o seu inicio, a intervenção parece ter sido bem sucedida na promoção de actividade física e perda de peso, tendo exercido influência positiva ao nível das principais variáveis-alvo mediadoras (por comparação com o grupo de controlo). Este estudo evidenciou a possibilidade de manipulação experimental das principais características sóciocontextuais identificadas pela TAD como fundamentais na promoção de estilos de vida activos, compatíveis com a eficaz gestão do peso. Os estudos 3 e 4 representam a passagem do estudo do impacto da intervenção para a procura de entendimento dos principais mecanismos motivacionais envolvidos. Com recurso ao teste de modelos mediacionais, procurou-se estudar o efeito diferenciado das variáveis-alvo identificadas pela TAD na adopção de diferentes tipos de actividade física um ano após o inicio da intervenção (estudo 3), bem como o papel das referidas variáveis na adesão continuada à actividade física (follow-up 2º ano), e alteração do peso a longo prazo (follow-up 3º ano). De forma congruente com investigações anteriores, mas estendendo-as a um enquadramento experimental e controlado, os resultados encontrados sustentam a percepção de um clima de suporte à satisfação das necessidades psicológicas básicas (autonomia e competência), e a motivação intrínseca, como mediadoras dos efeitos produzidos pela intervenção na adesão à actividade física estruturada. Estas variáveis funcionaram também como mecanismos associados ao envolvimento continuado em actividades físicas (dois anos após o início da intervenção) e controlo do peso a longo prazo (3 anos após o início da intervenção). Com base nos resultados encontrados, esta aplicação da TAD à promoção da actividade física e do controlo do peso fornece evidência experimental de que um clima de suporte ao desenvolvimento de autonomia e competência pode facilitar a internalização de regulações motivacionais mais autónomas para a actividade física, as quais se constituem como facilitadoras de mudanças comportamentais importantes e com relevância clínica, em mulheres com excesso de peso ou obesidade.

- Abstract
Rapid worldwide decreases in physical activity (PA), an increase in sedentary behaviour (SB) and poorer dietary patterns have been reported during COVID-19 confinement periods. However, as national variability has been observed, this study sought to describe PA, SB and eating patterns, and to explore their gender as well as other socio-demographic correlates and how they interrelate in a representative sample of Portuguese adults during the COVID-19 first mandatory social confinement. The survey was applied online and by telephone to 5856 adults (mean age = 45.8 years; 42.6% women). The majority reported high (46.0%) or moderate (20.5%) PA levels. Men, younger participants, those with higher education levels and a favourable perception of their financial situation reported higher PA levels, with the opposite pattern for SB. Physical fitness activities and household chores were more reported by women, with more strength training and running activities reported by men. Regarding eating behaviours, 45.1% reported changes, positive (58%) and negative (42%), with 18.2% reporting increases in consumption of fruit, vegetables, and fish and other seafood consumption, while 10.8% (most with lower educational level and less comfortable with their income) reported an increase in consumption of ready-to-eat meals, soft drinks, savoury snacks, and take-away and delivered meals. Two clusters—a health-enhancing vs. risky pattern—emerged through multiple correspondence analysis characterized by co-occurrence of high vs. low PA levels, positive vs. negative eating changes, awareness or not of the COVID-19 PA and dietary recommendations, perceived financial situation, higher vs. lower educational level and time in social confinement. In conclusion, while in social confinement, both positive and negative PA and eating behaviours and trends were displayed, highlighting the role of key sociodemographic correlates contributing to healthy vs. risky patterns. Results may inform future health interventions and policies to be more targeted to those at risk, and also advocate the promotion of PA and healthy eating in an integrated fashion.

- Abstract
Introduction: The majority of adolescents do not meet guidelines for healthy behaviours, posing major risks for developing multiple non-communicable diseases. Unhealthy lifestyles seem more prevalent in urban than rural areas, with the neighbourhood environment as a mediating pathway. How to develop and implement sustainable and effective interventions focused on adolescent health and well-being in urban vulnerable life situations is a key challenge. This paper describes the protocol of a Youth-centred Participatory Action (YoPA) project aiming to tailor, implement, and evaluate social and physical environmental interventions., Methods and Analysis: In diverse urban environments in Denmark, the Netherlands, Nigeria and South Africa, we will engage a dynamic group of 15-20 adolescents (12-19 years) growing up in vulnerable life situations and other key stakeholders (eg, policy makers, urban planners, community leaders) in local co-creation communities. Together with academic researchers and local stakeholders, adolescents will take a leading role in mapping the local system; tailoring; implementing and evaluating interventions during participatory meetings over the course of 3 years. YoPA applies a participatory mixed methods design guided by a novel Systems, User perspectives, Participatory co-creation process, Effects, Reach, Adoption, Implementation and Maintenance framework assessing: (i) the local systems, (ii) user perspectives, (iii) the participatory co-creation process, (iv) effects, (v) reach, (vi) adoption, (vii) implementation and (viii) maintenance of interventions. Through a realist evaluation, YoPA will explore why and how specific outcomes were reached (or not) in each setting (n=800-1000 adolescents in total)., Ethics and Dissemination: This study received approval from the ethics committees in Denmark, the Netherlands, Nigeria and South Africa and will be disseminated via various collaborative dissemination activities targeting multiple audiences. We will obtain informed consent from all participants. We envision that our YoPA co-creation approach will serve as a guide for participation of adolescents in vulnerable life situations in implementation of health promotion and urban planning in Europe, Africa and globally., Trial Registration Number: NCT06181162., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
