- 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.
- Analysing the Effects of Different Types of Exercise on Dyspnoea and Fatigue in Adults through COPD-Systematic Review and Meta-Analysis of Randomised Clinical TrialsPublication . Couto, Nuno; Cid, Luis; Alves, Susana; Brito, João; Pimenta, Nuno; Bento, TeresaBackground: Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition, the main symptoms of which are dyspnoea and fatigue. Though exercise has been recommended for subjects with COPD, its benefits remain unclear. The aim of this study was to summarise, through a systematic review and meta-analysis, the available evidence on the effects of aerobic, resistance, stretching, and combined exercise on the main symptoms of COPD. Methods: Search was performed using the electronic databases PubMed and Web of Science. Randomised controlled trials (RCTs) with interventions based on aerobic, resistance and/or combined exercise published until July 2022 were identified. The effects were summarised based on standardised mean differences (95% confidence intervals) using random and fixed effect models. Results: Eight studies were selected, including a total of 375 subjects. The results obtained showed that resistance exercise, aerobic exercise and combined exercise seem to improve dyspnoea and fatigue symptoms in COPD subjects. Conclusions: In general, we can conclude that exercise-based interventions appear to improve the main COPD symptoms and may benefit quality of life in this population.
- 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.
- 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.
- Atividade física e saúde mental. Efeitos de um programa de exercício físico em sujeitos com diagnóstico clínico de perturbações do humor e psicóticasPublication . Jesus, Alexandra; Mendes, Ana; Ferreira, Carla; Massano, Teresa; MOUTÃO, JOÃO; Brito, João; Cid, Luis; Bento, TeresaAtravés da realização desta investigação objetivamos estudar a influência que o programa de exercício tem na saúde física e mental de sujeitos com diagnóstico de perturbações de humor e psicóticas, nomeadamente, em indicadores antropométricos, na função cardiorrespiratória, no grau de satisfação com a vida, na vitalidade, na autoestima global, no fator positivo dos estados de humor (vigor) e num dos fatores negativos dos estados de humor (depressão). Desta forma, equacionamos a seguinte hipótese: a atividade física melhora a saúde dos sujeitos, existindo diferenças significativas nas variáveis antropométricas, fisiológicas e psicológicas em estudo entre o início e o fim do programa, bem como, entre os sujeitos do grupo experimental e do grupo placebo.
- Can group exercise programs improve health outcomes in pregnant women? A systematic reviewPublication . Jorge, Cristina; Santos-Rocha, Rita; Bento, TeresaCurrent scientific evidence supports the recommendation to initiate or continue the practice of physical exercise in healthy pregnant women. Group exercise programs have positive effects in improving health and well-being, as well as social support. In order to understand the scientific evidence in this field, and the outcomes in maternal health, it has generated wide interest in exploring the studies carried out with more relevant group exercise programs. The aim of this systematic review was to evaluate the available evidence on the effectiveness of group exercise programs in improving women’s and newborns health outcomes during pregnancy. Three databases were used to conduct literature searches and strict inclusion and exclusion criteria were employed. Seventeen studies were selected for analysis. All studies were randomized control trials conducted with pregnant women that evaluated the effect of group exercise programs on the health outcomes of mother and newborn. Most studies followed a supervised structured exercise program including a main aerobic part, resistance training, pelvic floor training and stretching and relaxation sections. The significant effects of the programs are related with improved maternal perception of health status, lower maternal weight gain, improved levels of maternal glucose tolerance, improved aerobic fitness and muscular strength, lower frequency of urinary incontinence, improved sick leave due to lumbopelvic pain, fewer cesarean and instrumental deliveries, higher newborn Apgar score and faster postpartum recovery. Exercise and health professionals should advise pregnant women that aerobic group exercise during pregnancy improves a wide range of health outcomes for the women and newborn
- Can Interpersonal Behavior Influence the Persistence and Adherence to Physical Exercise Practice in Adults? A Systematic ReviewPublication . Rodrigues, Filipe; Bento, Teresa; Cid, Luis; Neiva, Henrique Pereira; Teixeira, Diogo; Moutão, João; Marinho, Daniel; Monteiro, DiogoObjective: Motivation seems to be a fundamental indicator of long-term physical exercise adherence. Self-Determination Theory (SDT) argues that social environment plays a central role in the satisfaction of basic psychological needs, which might directly affect the quality of one’s motivation. Individuals who appear to be more self-determined tend to persist longer at certain behaviors. Therefore, this body of work intends to analyze the relationship between motivational variables and behavioral outcomes in the exercise context, having as theoretical background the Self-Determination Theory. Methods: This systematic review was conducted through an electronic search on Web of Science, PubMed, SPORTDiscus, and PsycINFO. Data such as instruments, main predictors and results were collected from studies published between 1985 and 2018. A total of 35 empirical studies were considered for a detailed analysis. Results: Results showed the relevance of autonomy support performed by exercise professionals, as well as the major contribution that these behaviors have toward the satisfaction of basic psychological needs, besides the inherent benefits of developing more autonomous regulations. According to the literature, few studies have analyzed interpersonal thwarting behavior and the way this relates to basic psychological needs’ frustration. Nether less, there seems to be a negative relationship between less self-determined regulations and exercise practice. Conclusion: Despite the existence of numerous cross-sectional studies that demonstrate positive correlations between SDT and behavioral outcomes in the exercise context, longitudinal research that analyzes all six dimensions of interpersonal behaviors and their relationship with persistence and adherence to exercise proves to be crucial. However, according to this review, interventions based on SDT appear to be fundamental when it comes to promote the maintenance of a long-term exercise practice.
- Crioterapia como tratamento de entorses de tornozelos de atletas: revisão sistemáticaPublication . Figueiredo, Rosa; Bento, Teresa; Mota, Paula; Fernandes, Cleonice; Leitão, JoséA crioterapia é prática comum na medicina esportiva, pela praticidade, facilidade de acesso e baixo custo, possuindo vantajoso uso na Saúde Pública. No entanto, os efeitos analgésicos do gelo tem pouca base objetiva e sistematizada em termos de técnicas, duração e frequência. O objetivo deste estudo foi sintetizar através da revisão sistemática (RS) as evidências relativas à efetividade da crioterapia para o tratamento das entorses de tornozelo de atletas. A RS é um método de pesquisa observacional e retrospectivo, pelo qual se tratam artigos, preferencialmente Ensaios Clínicos Aleatórios – ECA, como sujeitos da investigação, com rigorosos critérios de inclusão e exclusão e, quando possível, realiza-se uma macro estatística dos resultados – metaanálise. No presente RS, foram consultados cinco bancos de dados - Medline, Embase, Cochrane, Lilacs e PEDro para buscar ECA sobre crioterapia com os desfechos dor, edema, rigidez e função. Resultados: 289 estudos foram identificados inicialmente, dos quais nove com tratamentos isolados ou associados à crioterapia, porém apenas um preencheu aos critérios de inclusão, cujo N era 121 atletas, dos quais 64 receberam a crioterapia (funcional) e 57 no grupo controle (imobilização). Maior probabilidade para o evento dor foi observada no grupo controle, após 3 e 12 meses. A RS revelou uma lacuna em ECA dentro do tema, mas não encontrou efeito adverso na prática da crioterapia, sendo um princípio analgésico importante, sobretudo em lesões de tecidos moles.
- 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.
