- Age and sex differences in physical activity of portuguese adults and older adultsPublication . Bento, Teresa; Mota, Maria P.; Vitorino, Anabela; Monteiro, Diogo; Cid, Luis; Couto, NunoThis study aims to explore data on objectively measured physical activity from a sample of adults and older adults and to investigate the achievement of the minimum physical activity required for health benefits. Participants, 257 women (age 58.99 ± 18.93 years, BMI 26.75 ± 4.57 kg·m−2 ) and 178 men (age 49.22 ± 20.39 years, BMI 26.81 ± 3.51 kg·m−2 ), wore an accelerometer for 4 to 7 days. Approximately 40% of the time was spent daily in sedentary behaviors during waking hours. Our results do not sustain the suggestion that adult men are more physically active than women. The results indicated a decrease in intensity of physical activity with age, in men and women, but not in successive age groups. Around 75% of adults and 30% of older adults accumulated the minimum daily physical activity for health benefits, in periods shorter than 10 min, above moderate intensity. The number of steps taken per day revealed that most men and women (except the oldest) attained or exceeded the lower threshold for deriving health benefits. To obtain relevant health benefits, future physical activity interventions should aim at reversing the amount of sedentary behaviors, emphasizing increments in, at least, the lower levels of PA, and maintaining walking habits.
- Analysis of the Effect of Different Physical Exercise Protocols on Depression in Adults: systematic Review and Meta-analysis of Randomized Controlled TrialsPublication . Correia, Érica M.; Monteiro, Diogo; Bento, Teresa; Rodrigues, Filipe; Cid, Luis; Vitorino, Anabela; Figueiredo, Nuno; Teixeira, Diogo S.; Couto, NunoContext: Physical exercise (PE) is an effective treatment for depression, alone or as an adjunct. Objective: There is a lack of indicators regarding the frequency, intensity, duration, and type of physical exercise (PE). This study aims to synthesize and analyze the dose-effect of different PE protocols in adult subjects in the treatment of depression, based on the analysis of randomized controlled trials (RCTs). Data Sources: The search was conducted using Web of Science, PubMed, and Cochrane Library electronic databases. Study Selection: Studies with an exercise-based intervention published by December 31, 2021 were identified. RCTs and meta-analyses involving adults with depression were also included; 10 studies were selected, including a total of 956 subjects. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 1. Results: Effect sizes were summarized using standardized mean differences (95% confidence interval) by effected randomized models. The results reinforce that exercise appears to be beneficial in improving depression among adults aged 18 to 65 years. Interventions lasting above 150 minutes per week of moderate intensity and group interventions seem to have a more significant effect on reducing depression. Studies have revealed that aerobic exercise, compared with resistance or flexibility, has a more positive effect on depression. Conclusion: PE can be a way to reduce depression and can be used as a possible adjunctive tool for pharmacological and/or alternative treatments. Considering the findings of this study, it is important that health professionals (eg, exercise physiologists, physicians, nurses, psychologists) promote the practice of PE as a complementary alternative and act early to prevent the worsening of depression.
- Aptidão física e qualidade de vida em indivíduos com deficiência intelectual e de desenvolvimentoPublication . Jacinto, Miguel; Brito, João; Oliveira, Rafael; Martins, Alexandre; Francisco, Ruben; Vitorino, AnabelaA maioria dos indivíduos com Deficiência Intelectual e de Desenvolvimento (DID) adota um estilo de vida sedentária e inativa, tendo consequentemente fraca capacidade funcional e de composição corporal, apresentando uma relação com o seu estado de saúde. Avaliar a composição corporal e averiguar a sua influência com a capacidade funcional/aptidão física, numa população com DID. 16 indivíduos com DID avaliados na composição corporal por bio impedância multifrequência, capacidade funcional e força dos membros inferiores, com recurso a dinamómetro isocinético. Não se verificaram diferenças, na capacidade funcional e nas variáveis da composição corporal, entre grupos com diferentes gras de deficiência. Verificou-se correlações entre o género diferenças significativas, na capacidade funcional e nas variáveis da composição corporal, entre grupos com diferentes graus de deficiência. Verificaram-se correlações entre o género e as variáveis da composição corporal, apresentando o género masculino valores mais favoráveis nas variáveis percentagem de massa gorda (%MG) (r= -0,758; p=0,001), gordura visceral (GV) (r= -0,589; p=0,016), massa celular corporal (MCC) (r= 0,625; p=0,010), água extra celular (AEC) / água corporal total (ACT) (r= -0,607; p=0,013) e no ângulo de fase (AF) a 50khz (r= 0,529; p=0,035). O rácio ACT/massa isenta de gordura (MIG) e o rácio AEC/ACT apresentam valores de indivíduo saudável, respetivamente, 73,26±0,36% e 0.36-0.39%. O AF foi menor no género feminino e nas idades mais avançadas, bem como com o aumento da %MG. O grau de deficiência parece não influenciar a capacidade funcional e as variáveis da composição corporal, nesta amostra. De salientar, o AF que reflete a boa integridade celular relacionado à proporção de AEC e de água intracelular, apresenta valores dentro dos parâmetros normais, ainda que baixos.
- Assessment in sport and exercise psychology: considerations and recommendations for translation and validation of questionnairesPublication . Cid, Luis; Monteiro, Diogo; Teixeira, Diogo Santos; Evmenenko, Anastasiia; Andrade, Ana; Bento, Teresa; Vitorino, Anabela; Couto, Nuno; Rodrigues, FilipeTranslating and validating measurement instruments in sport and exercise psychology is not an easy task. Rather, it is a task that requires effort and time, for the process is not limited to a simple translation to translate words from one language to another, just in order to make valid and reliable measure. All researchers should be aware that the only proper way is to adopt rigorous and robust methodologies to conduct the process from the preliminary stage of translation to reaching the validation stage of the psychological variable. Only so is it possible to avoid creating fragile and inadequate psychological assessment instruments that can jeopardize the entire investigation to be held with its use. Thus, the main objective of this work is to promote reflection and discussion on the subject by presenting some considerations and recommendations about translation and validation of questionnaires for psychological assessment applied to sport and exercise domain.
- Atividade física adaptada na população com necessidades especiaisPublication . Vitorino, Anabela; Monteiro, Diogo; MOUTÃO, JOÃO; Morgado, Sónia; Bento, Teresa; Cid, LuisNa área da deficiência exige-se a intervenção de técnicos de diversas especialidades, atuando de forma articulada e concertada para responder às necessidades das pessoas com necessidades especiais. Neste contexto, o papel da atividade física, quando inserida em estilos de vida saudáveis, merece particular destaque, enquanto instrumento essencial para a melhoria da condição física, da qualidade de vida e do bem-estar das pessoas com deficiência. O conceito de atividade física na população com deficiência está igualmente associado a vertentes como a reabilitação, educação, competição e recreação, sendo cada vez mais evidente a ênfase colocada nos seus benefícios físicos, sociais e psicológicos. Em suma: a atividade física adaptada parece poder contribuir para desencadear efeitos positivos na sua saúde. O objetivo principal foi consolidar a visão estrutural e teórica do conceito de deficiência, necessidades especiais, atividade física adaptada e estilos de vida saudáveis.
- Behavioral Regulation Sport Questionnaire: Gender and Sport Invariance in Portuguese AthletesPublication . Monteiro, Diogo; Teixeira, Diogo; Vitorino, Anabela; Moutão, João; Rodrigues, Filipe; Machado, Sérgio; Cid, LuisThis study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across the gender and four different sports. In addition, we examined nomological validity via basic psychological needs satisfaction. Participants totaled 1,812 Portuguese athletes (1,220 males and 592 females; aged 15–59 years, Mage ¼ 17.72, SD ¼ 5.51) from football (n ¼ 596), basketball (n ¼ 273), swimming (n ¼ 800), and parasport (n ¼ 143). The BRSQ measurement model was invariant across the gender and these four sports. The scale confirmed nomological validity in that satisfaction of the basic psychological needs positively predicted autonomous forms of motivation and negatively predicted more controlled motivation and amotivation as suggested by self-determination theory. In light of this evidence for BRSQ construct validity, composite reliability, nomological validity, and invariance across the gender and four different sports, this scale is a useful tool for the coaches of the aforementioned sports in their efforts to evaluate their athletes’ motivation.
- Conteúdo dos objetivos para a prática de exercício físico e vitalidade subjetiva na população idosa - Análise de medição das necessidades psicológicas básicasPublication . Couto, Nuno; Antunes, Raúl; Monteiro, Diogo; Vitorino, Anabela; Cid, LuisEste estudo teve como objetivo compreender a associação entre os conteúdos dos objetivos para a prática de atividade física e a vitalidade subjetiva numa população idosa portuguesa, bem como analisar o efeito de medição das necessidades psicológicas básicas (NPB). Recorreu-se a uma amostra de 299 idosos (234 femininos, 65 masculinos), residentes em Portugal continental, com idades compreendidas entre os 60 e os 90 anos (M=68.43; SD=6.48) e procedeu-se a uma análise de medição simples através do modelo quatro do Process Macro para o SPSS versão 3.5. Através dos resultados obtidos verificou-se que todos os objetivos apresentam uma associação significativa com a satisfação global das NPB e com a vitalidade subjetiva (neste caso, com exceção do objetivo reconhecimento social). Verificou-se ainda que as NPB medeiam a relação entre o conteúdo dos objetivos para a prática de atividade física, saúde, desenvolvimento de capacidades, imagem e a vitalidade subjetiva.
- Desenvolvimento e validação de um questionário de avaliação da satisfação dos alunos com os docentes e a unidade curricular (SADUC)Publication . Cid, Luis; Vitorino, Anabela; Borrego, Carla Chicau; MOUTÃO, JOÃO; Bento, TeresaO objetivo principal deste trabalho foi a validação de um questionário de avaliação da Satisfação dos Alunos com o Docente e a Unidade Curricular, desenvolvido como alternativa de medida de um dos parâmetros da avaliação de desempenho docente, determinando as suas qualidades psicométricas iniciais, com recurso a uma análise fatorial exploratória e confirmatória. Participaram neste estudo, de forma anónima, 216 alunos dos cursos da ESDRM-IPS e o instrumento utilizado, desenvolvido especificamente para o efeito, é constituído por 3 fatores e 15 itens, aos quais se responde numa escala de Likert de 7 níveis. Os resultados principais revelaram qualidades psicométricas iniciais bastante promissoras, quer de validade do construto, quer de fiabilidade, embora a análise dos parâmetros individuais nos indique alguma redundância subjacente a determinados itens, o que nos sugere a hipótese de aglomeração dos mesmos. No entanto, podemos concluir que este questionário poderá ser utilizado com um elevado grau de confiança, na avaliação da satisfação dos alunos com os docentes e as unidades curriculares.- The main purpose of this study was to validate a questionnaire that evaluates students´ satisfaction with their teacher and with the curricular unit. This questionnaire was developed as an alternative measurement method of the teacher´s performance, determining his initial psychometric qualities, and using an exploratory and confirmatory factor analysis. 216 students of the ESDRM-IPS participated in this study, anonymously. The questionnaire, developed specifically for this purpose, included three factors and 15 items, where answers were given in a seven level Likert scale. The main results showed a very promising initial psychometric qualities, whether considering the construct validity or reliability scores, however the analysis of the individual parameters indicated some redundancy underlying certain items, which suggests the possibility of clustering. Nevertheless, we conclude that this questionnaire can be used with a high degree of confidence to measure students´ satisfaction with teachers and with the curricular units.
- Determinants and reasons for dropout in swimming – systematic reviewPublication . Monteiro, Diogo; Cid, Luis; Marinho, Daniel; Moutão, João; Vitorino, Anabela; Bento, TeresaThe present research aims to systematically review the determinants and reasons for swimming dropout. The systematic review was conducted through electronic searches on the Web of Knowledge and PsycInfo databases from 2 February to 29 July 2015, using the keywords dropout, withdrawal, motives, reasons, sport, framework-theories, motivation, swim*, review, attrition and compliance. Fifteen studies were found and six were fully reviewed and its data extracted and analysed. Most studies were undertaken in Canada and in the United States of America (USA), and one study was conducted in Spain. Most participants were female (65.74%), and the main reasons for dropout were ‘conflicts with their trainers’, ‘other things to do’, ‘competence improvements’ failure’, ‘parents, couples or trainers’ pressure’, ‘lack of enjoyment’ and ‘get bored’. This review contributes to the present knowledge on the understanding of dropout in swimming. However, it is necessary to continue researching on this topic, validating measurement instruments and studying the motivational processes related to dropout and persistence.
- Effects of exercise on quality of life in subjects with Alzheimer’s disease: systematic review with meta-analysis of randomized clinical trialsPublication . Mendes, Mariana; Correia, Érica; Vitorino, Anabela; Rodrigues, José; Cid, Luis; Bento, Teresa; Antunes, Raul; Monteiro, Diogo; Couto, NunoAlzheimer’s disease is a type of dementia that progressively affects memory, thinking, and behavior. It can interfere with daily activities and lead to a decline in cognitive abilities over time. Exercise-based interventions can complement Alzheimer’s disease treatment. Exercise is a valuable tool in all healthcare settings and has shown promise as an effective cognitive improvement intervention for people with cognitive impairments. This systematic review and meta-analysis aimed to analyze the effect of physical exercise on the QoL of subjects with Alzheimer’s disease. A search was performed with the help of the electronic databases PubMed and Web of Science. Randomized controlled trials with exercise-based interventions were selected. Four studies met the inclusion criteria, which included interventions based on exercise. The effects were summarized using standardized mean differences (95% confidence intervals) using random-effect models. The results showed that exercise had no significant effect on the QoL of subjects with Alzheimer. Thus, the effect of exercise interventions on the QoL of patients with Alzheimer’s disease is not conclusive. More research is needed about this topic and the way in which the QoL is assessed; the necessity to conduct an objective way to assess the QoL in this population is mandatory.
