- Adaptation and validation of the Portuguese version of Basic Psychological Needs Exercise Scale (BPNESp) to the sport domain and invariance across football and swimmingPublication . Monteiro, Diogo; Marinho, Daniel Almeida; MOUTÃO, JOÃO; Couto, Nuno; Antunes, Raúl; Cid, LuisThe purpose of this study was to adapt and validate the Basic Psychological Needs Exercise Scale (BPNESp) to the sport domain, and to measure model invariance across football and swimming. Athletes (n=1382; 623 football, 759 swimming) with an average age of 18.77±SD 7.04 years participated in this study. Results supported the suitability of both the first and second order models, showing that the model was well adjusted to the data. In addition, the model showed the discriminant and convergent validity and composite reliability of the factors, and was invariant between football and swimming (ΔCFI≤.01).
- 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.
- Basic psychological needs and subjective well-being in portuguese older peoplePublication . Couto, Nuno; Antunes, Raul; Monteiro, Diogo; MOUTÃO, JOÃO; Marinho, Daniel; Cid, LuisThe 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 significante ffect 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.
- 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.
- Effect of different types of exercise in adult subjects with fibromyalgia: a systematic review and meta-analysis of randomised clinical trialsPublication . Couto, Nuno; Monteiro, Diogo; Cid, Luis; Bento, TeresaExercise has been recommended for fibromyalgia treatment. However, doubts related to exercise benefits remain unclear. The objective of this study was to summarise, through a systematic review with meta-analysis, the available evidence on the effects of aerobic, resistance and stretching exercise on pain, depression, and quality of life. Search was performed using electronic databases Pubmed and Cochrane Library. Studies with interventions based on aerobic exercise, resistance exercise and stretching exercise published until July 2020 and updated in December 2021, were identified. Randomized controlled trials and meta-analyses involving adults with fibromyalgia were also included. Eighteen studies were selected, including a total of 1184 subjects. The effects were summarised using standardised mean differences (95% confidence intervals) by random effect models. In general, aerobic exercise seems to reduce pain perception, depression and improves quality of life; it also improves mental and physical health-related quality of life. Resistance exercise decreases pain perception and improves quality of life and moreover improves the physical dimension of health-related quality of life. It was also observed that resistance exercise appears to have a non-significant positive effect on depression and the mental dimension of health-related quality of life. Studies revealed that stretching exercise reduces the perception and additionally improves quality of life and health-related quality of life. However, a non-significant effect was observed on depression. We conclude that exercise may be a way to reduce depression, and pain and improve the quality of life in adult subjects with fibromyalgia and should be part of the treatment for this pathology.
- 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.
- Goal Content for the practice of physical activity and the impact on subjective well-being in older adultsPublication . Antunes, Raul; Couto, Nuno; Monteiro, Diogo; Moutão, João; Marinho, Daniel; Cid, LuisThe main goal of this study consisted in an analysis of the impact that the goal content that leads to the practice of physical activity in the elderly population can play on the variables that constitute subjective well-being, as well as to analyze the differences in these variables’ levels according to the amount of physical activity practiced. A total of 300 individuals participated in this study (n=300), including 238 females and 62 males, aged between 60 and 90 years old (M = 68.59; DP = 6.54), who practice differing levels of physical activity. The results enable us to conclude that the goal content for the practice of physical activity has positive effects on the perception of satisfaction with life and on affect. To the same extent, they verify that health is the motivation that has the greatest weight on the practice of physical activity. We also concluded that elderly people who practice more physical activity perceive higher levels of satisfaction with life and positive affect, and lower levels of negative affect
