- 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.
- 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.
- 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.
- 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.
