- A associação entre o estilo de vida e a atitude de alunos do ensino básico e secundário em relação à disciplina de educação físicaPublication . Gouveia, Élvio Rúbio; Ihle, Andreas; Rodrigues, Ana; Correia, Ana Luisa; Alves, Ricardo; Simões, Joana; Gouveia, Bruna; Kliegel, Matthias; Freitas, Duarte; Lopes, HelderEste estudo teve por objetivo o seguinte: investigar a associação entre o estilo de vida e a atitude positiva (EñgEFD) ou negativa (EgEFD) dos alunos sobre a Educação Física (EF). Um estudo de natureza transversal foi conduzido em 243 estudantes (15.6 ±2.5 anos). A informação demográfica, a opinião sobre a EF, e a auto perceção foram avaliados através de questionários. A aptidão física foi determinada a partir da FITNESSGRAM e da EUROFIT. A percentagem de gordura foi estimada a partir das equações de Slaughter et al., (1988). Análises descritivas e o t-test de medidas independentes foram conduzidas nas análises. Nesta amostra, 74.5% dos estudantes afirmam gostar de EDF. Os EgEFD apresentam scores significativamente mais elevados comparativamente aos EñgEFD na força, velocidade/agilidade, força resistência do tronco e resistência aeróbia (p<.007). Os EgEFD têm uma melhor percepção das suas capacidades físicas, assim como referem ter uma boa saúde e adotarem estilos de vida mais saudáveis (p<.001). Os EgEFD apresentam um perfil funcional e psicológico mais saudável, auto percecionam um melhor estado de saúde e preferem envolver-se em atividades físicas em detrimento das atividades sedentárias no seu dia-a-dia.
- Balance and mobility relationships in older adults: A representative population-based cross-sectional study in Madeira, PortugalPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Ihle, Andreas; Kliegel, Matthias; Marques, Adilson; Freitas, Duarte L.Background: Balance and mobility impairments are important modifiable risk factors associated with falls in older people. Purpose: To investigate how different functional fitness components relate to balance and mobility, after controlling for age, sex, body mass index (BMI), and different physical activity (PA) domains. Methods: This representative cross-sectional study included 802 individuals, 401 males and 401 females (69.8 ± 5.6 years) from Madeira, Portugal. The Fullerton Advance Balance (FAB) scale was used to assess balance. Mobility in terms of gait velocity, cadence, stride length, and gait stability ratio (GSR) were assessed using the 50-foot Walk test. PA was assessed through a face-to-face interview using the Baecke questionnaire, and functional fitness was assessed with Senior Fitness tests (strength, flexibility, and aerobic endurance). Results: Balance and mobility were negatively associated with age and BMI, and positively related to PA and functional fitness. Moreover, male presented better performance in balance and mobility. Hierarchical multiple regression analyses showed that functional fitness explained the highest amount of variance in balance and all mobility parameters(over andaboveage,sex,BMI,and PA).Specifically, entering functional fitnesscomponents significantly increased explained variance in FAB (+19%), gait velocity (+25%), cadence (+15%), stride length (+9%), and GSR (+ 31%). In these models, aerobic endurance consistently had the strongest contribution. Conclusion: Strength, flexibility, and especially aerobic endurance, over and above non-modifiable variables like age and sex, are crucial for maintaining or improving balance and mobility and, thereby, prevent falls in older people.
- Bidirectional Association between Physical Activity and Dopamine Across Adulthood—A Systematic ReviewPublication . Marques, Adilson; Marconcin, Priscila; Werneck, André O.; Ferrari, Gerson; Gouveia, Élvio R.; Kliegel, Matthias; Peralta, Miguel; Ihle, AndreasPhysical activity (PA) may influence the secretion of neurotransmitters and thereby have positive consequences for an individual’s vulnerability (i.e., reducing anxiety and depressive symp toms). This systematic review aims to analyse the potential bidirectional effects of exercise on dopamine from young adulthood to old age. The article search was conducted in PubMed, Scopus, and Web of Science in December 2020. The inclusion criteria were longitudinal and experimental study design; outcomes included dopamine and exercise; effect of exercise on dopamine and vice versa; adults; and articles published in English, Portuguese, or Spanish. Fifteen articles were included in the review. We observed robust findings concerning the potential effects of PA on dopamine, which notably seem to be observable across a wide range of participants characteristics (including age and sex), a variety of PA characteristics, and a broad set of methods to analyse dopamine. By contrast, regarding the potential effects of dopamine on PA, findings were mixed across studies. Thus, there are robust effects of physical exercise on dopamine. These findings further strengthen the idea that innovative approaches could include PA interventions for treating and preventing mental disorders. Therefore, it seems that PA is a potential alternative to deal with mental health issues.
- Cognitive function and its associations in older adults from Amazonas, BrazilPublication . Freitas, Duarte Luís; Gouveia, Bruna Raquel; Ribeiro, Euler Esteves; Muniz, Bárbara Régia; Odim, Angeany Pinto; Machado, Floramara Teles; Jurema, Jefferson; Kliegel, Matthias; Ihle, Andreas; Gouveia, Élvio Rúbio; Tinôco, Maria Antonieta de CamposThe objectives of this study were: (1) to investigate the age-related differences in cognitive function (CF), nutritional status (MNA), physical activity (AF), quality of life (QoL), depression, social satisfaction (SS) and socioeconomic status (SES), and (2) to explore the relationships between CF and the previous variables. This cross sectional study included 268 men and 433 women (aged 71.4 ± 7.0 years). CF was determined with the Cognitive Telephone Screening Instrument (COGTEL) and the Mini-Mental State Examination (MMSE). Correlates were as follows: Mini Nutritional Assessment (MNA), PA (Baecke questionnaire modified for older adults), Quality of life (QoL SF12), Geriatrics Depression Scale (GDS), Satisfaction and Social Support Scale, and Socioeconomic status (SES). All instruments were applied in a face to face interview. An independent t-test identified significantly higher scores in young-old adults (≤ 69 years) for CF (p < 0.001), PA (p = 0.046) and SES (p = 0.007), compared to old-old adults (≥ 70 years). The results of multiple linear regression analysis indicated that the most significant CF correlates were SES (β = 0.45; p < 0.001), age (β = -0.12; p < 0.001), SS (β = 0.12; p = 0.001), GDS (β = -0.11; p = 0.003) and QoL (β = 0.08; p = 0.017). The overall regression model explained 36% of the total variance in the COGTEL. The oldest and the more depressed adults obtained lower scores for FC. The present study suggests that, between the correlates studied, SES was the strongest predictor in the explanation of CF in older adults.
- Cognitive Functioning Mediates the Association of Cognitive Reserve with Health-Related Quality of LifePublication . Ihle, Andreas; Gouveia, Élvio R.; Gouveia, Bruna R.; Marques, Adilson; Marconcin, Priscila; Nascimento, Marcelo de Maio; Jurema, Jefferson; Tinôco, Maria A.; Kliegel, MatthiasWe investigated whether the relations of the cognitive reserve markers education and cogni tive level of work to the physical and the mental component of health-related quality of life (HRQoL) were mediated via cognitive functioning in a large sample of 701 older adults (mean age = 70.36 years, SD = 6.87). HRQoL was measured with the 12-item Short-Form Health Survey. To measure cog nitive functioning, we used the COGTEL, which is a cognitive test battery assessing prospective memory, verbal short-term memory, verbal long-term memory, working memory, verbal fluency, and inductive reasoning, combined into a composite score. Individuals reported information on their education and their main profession during their working life. Mediation analyses showed that better cognitive functioning mediated the association of higher values in the cognitive reserve markers (longer education and a high cognitive level of work) with higher HRQoL. In conclusion, the present study suggests that the sustainability of cognitive functioning in old age with the help of cognitive reserve is fundamental for the sustainability of quality of life, presumably particularly for the mental HRQoL component.
- Cognitive reserve attenuates 6-year decline in executive functioning after strokePublication . Ihle, Andreas; Gouveia, Élvio R.; Gouveia, Bruna R.; Cheval, Boris; Sieber, Stefan; Cullati, Stéphane; Kliegel, MatthiasAims: We investigated whether the longitudinal relationship between history of stroke and subsequent decline in executive functioning over 6 years differed by cognitive reserve. Methods: We analyzed longitudinal data from 897 older adults (mean age, 74.33 years) tested on the Trail Making Test (TMT) in two waves 6 years apart. Participants reported information on key frequently used proxies of lifelong cognitive reserve accumulation (i.e., education, occupation, and leisure activity engagement), and history of stroke. Results: There was a significant interaction of stroke with leisure activity engagement on latent change in executive functioning. Specifically, only for individuals with low (but not those with high) leisure activity engagement, history of stroke significantly predicted a steeper subsequent decline in executive functioning across 6 years (i.e., increases in TMT completion time). Conclusion: The detrimental aftereffects of stroke on subsequent decline in executive functioning may be attenuated in individuals who have accumulated greater cognitive reserve through leisure activity engagement across their life.
- Cognitive Reserve Mediates the Relation between Neighborhood Socio-Economic Position and Cognitive DeclinePublication . Ihle, Andreas; Gabriel, Rainer; Oris, Michel; Gouveia, Élvio R.; Gouveia, Bruna R.; Marques, Adilson; Marconcin, Priscila; Kliegel, MatthiasWe investigated the mediating role of leisure activity engagement as marker of cognitive reserve in the relation between neighborhood socio-economic position (SEP) and cognitive decline over 6 years. Methods: The study analyzed longitudinal data from 897 older adults who par ticipated in the two waves (2011 and 2017) of the Vivre-Leb en-Vivere (VLV) survey in Switzerland (M = 74.33 years in the first wave). Trail Making Test parts A and B were adminis tered in both waves. Leisure activity engagement was as sessed during interviews. Neighborhood SEP was derived from the Swiss Neighborhood Index of Socio-Economic Position (Swiss-SEP), provided by the Swiss National Cohort (SNC). Results: Latent change score modeling revealed that 42.5% of the relationship between higher neighborhood SEP and smaller cognitive decline was mediated via a higher frequency of leisure activities in the first wave. Conclusion: Neighborhood SEP constitutes an important contextual fac tor potentially influencing the pathways of cognitive reserve accumulation and, therefore, should be taken into account to better understand their effects on cognitive decline in old age.
- Correlações da qualidade de vida relacionada à saúde em pessoas Idosas da Região Autónoma da MadeiraPublication . Gouveia, Élvio R.; Gouveia, Bruna R.; Ihle, Andreas; Marques, Adilson; Kliegel, Matthias; Freitas, Duarte L.O objetivo deste estudo foi investigar o papel dos preditores da qualidade de vida relacionada com a saúde (QVRS) em pessoas idosas, e analisar se essas relações diferem em função da componente da QVRS (física vs. mental) e/ou intervalo etário (jovem-idoso vs. idoso-idoso). Este estudo incluiu 802 idosos com idade entre 60 e os 79 anos. A QVRS foi avaliada através do questionário SF-36. A aptidão funcional foi avaliada usando a bateria de testes Senior Fitness Test. A atividade física, as informações demográficas e de saúde foram obtidas via questionário. Uma análise de regressão múltipla mostrou que o índice de massa corporal (β=−0,15, p=0,001), a força muscular (β=0,21, p<0,001), a resistência aeróbia (β=0,29, p<0,001), a atividade física (β=0,11, p=0,007), os sintomas depressivos (β=−0,19, p<0,001), as quedas (β=−0,19, p<0,001) e viver sozinho (β=−0,16, p<0,001) foram preditores significativos do score total do SF-36. Verificou-se ainda uma relação positiva entre a componente física com a resistência aeróbia, e uma relação negativa entre o viver sozinho componente mental da QVRS. A relação positiva entre a atividade física e a QVRS foi verificada apenas nos idosos-idosos. Estes dados sugerem que a composição corporal, a aptidão funcional, os fatores psicossociais e as quedas são preditores importantes da QVRS. Existem diferenças nas relações entre as componentes da QVRS e os preditores em função do intervalo etário, o que sugere a necessidade de planear estratégias específicas no nível da comunidade para promover a QVRS em pessoas idosas mais velhas.
- Correlates of health-related quality of life in young-old and old–old community-dwelling older adultsPublication . Gouveia, Élvio R. Quintal; Gouveia, Bruna R.; Ihle, Andreas; Kliegel, Matthias; Maia, José A.; Bermúdez i Badia, Sergi; Freitas, Duarte L.Purpose This study aimed (1) to examine the role of potential correlates of HRQoL in a large representative sample of older adults, and (2) to investigate whether the relationships between HRQoL and potential factors differ as a function of HRQoL component (physical vs. mental) and/or age cohort (young-old vs. old–old). Methods This cross-sectional study included 802 older adults aged 60–79 years old. HRQoL was assessed using the SF-36 questionnaire. Functional fitness was assessed using the Senior Fitness Test. Physical activity was measured via the Baecke questionnaire. Demographic information, mental and health features were obtained through questionnaires. Results A multiple regression analysis showed that BMI (β = −0.15, p = 0.001), body strength (β = 0.21, p < 0.001), aerobic endurance (β = 0.29, p < 0.001), physical activity (β = 0.11, p = 0.007), depressive symptoms (β = −0.19, p < 0.001), falls (β = −0.19, p < 0.001), and living alone (β = −0.16, p < 0.001) were all significantly related to HRQoL-SF-36 total score. The positive relation with aerobic endurance was significantly higher for the physical component of HRQoL, while the negative relation with living alone was significantly higher for the mental component. The positive relation of HRQoL with physical activity was significantly higher in old–old compared to young-old adults. Conclusion This data suggest that body composition, functional fitness, psycho-social factors, and falls are important correlates of HRQoL in old age. There are HRQoL-component and age-cohort differences regarding these correlates, underlying the need for specific strategies at the community level to promote HRQoL in older adults.
- O ensino da educação física: contributos da investigação sobre os modelos de ensino centrados no alunoPublication . Gouveia, Elvio Rúbio; Lopes, Helder; Rodrigues, Ana; Gouveia, Bruna; Caldeira, Romualdo; Freitas, Rúben; Alves, Ricardo; Correia, Ana; Antunes, Hélio; Marques, Adilson; Kliegel, Matthias; Ihle, AndreasA literacia científica em Educação Física tem proporcionado um aumento signi ficativo do conhecimento sobre as estratégias de ensino-aprendizagem mais apro priadas ao desenvolvimento de competências do aluno, em particular no contexto dos jogos desportivos coletivos. Um exemplo da importância da Educação na pro moção da literacia científica no contexto dos jogos desportivos coletivos é o projeto de investigação “Educação Física nas Escolas da RAM – Compreender, Intervir, Transformar”. Esta investigação tem discutido o efeito da utilização de modelos de ensino centrados no aluno, influenciados por ideias construtivistas e cognitivistas. A utilização destas novas abordagens no ensino dos jogos desportivos coletivos é a resposta da Escola à forma como deve preparar os seus alunos para se envolverem de forma positiva em atividades desportivas ao longo da vida.
