Introduction Institutionalization in a nursing home restricts autonomy, most notably free will, free choice, and free action. Decreased physical activity and fitness are predictive of disability and dependence (Rikli & Jones, 2013; Tak, Kuiper, Chorus, & Hopman-Rock, 2014); however little is known about the impact of these factors on institutionalization. Thus, this study aimed to analyze the impact of physical activity and fitness and on the risk of elderly people without cognitive impairment become institutionalized. Methods This cross-sectional study involved 195 non-institutionalized (80.14.4yrs) and 186 institutionalized (83.85.2yrs) participants. Cognitive impairment was assessed using Mini-Mental State Examination, physical activity was assessed using the International Physical Activity Questionnaire, and measures of physical fitness were determined by the Senior Fitness Test. Results: Multivariate binary logistic analysis selected 4 main predictors of institutionalization in both genders. The likelihood of becoming institutionalized increased by +18.6% for each additional year of age, while it decreased by -24.8% by each fewer kg/m2 in BMI, by -0.9% for each additional meter performed in the aerobic endurance test and by -2.0% for each additional 100MET-min/wk of physical activity expenditure (p<0.05). Values ≤50th percentile (age ≥81yrs, BMI≥26.7kg/m2, aerobic endurance ≤367.6m, and physical activity ≤693MET-min/wk) were computed using Receiver Operating Characteristics analysis as cut-offs discriminating institutionalized from non-institutionalized elderly people. Conclusion The performance of physical activity, allied to an improvement in physical fitness (mainly BMI and aerobic endurance) may prevent the institutionalization of elderly people without cognitive impairment only if they are above the 50th percentile; the following is highly recommend: expending ≥693MET-min/wk on physical activity, being ≤26.7kg/m2 on BMI, and being able to walk ≥367.6m in the aerobic endurance test, especially above the age of 80 years. The discovery of this trigger justifies the development of physical activity programs targeting the pointed cut-offs in old, and very old people. References Rikli, R., & Jones, C. (2013).

Aim: to evaluate the effects of a 12-weeks combined aerobic-resistance exercise therapy on fatigue and isokinetic muscle strength, glycemic control and health-related quality of life (HRQoL) in moderately affected type 2 diabetes (T2DM) patients. Methods: a randomized controlled trial design was employed. Forty-three T2DM patients were assigned to an exercise group (n = 22), performing 3 weekly sessions of 60 minutes of combined aerobic-resistance exercise for 12-weeks; or a no exercise control group (n = 21). Both groups were evaluated at a baseline and after 12-weeks of exercise therapy for: 1) muscle strength and fatigue by isokinetic dynamometry; 2) plasma glycated hemoglobin A1C (HbA1C); and 3) HRQoL utilizing the SF-36 questionnaire. Results: the exercise therapy led to improvements in muscle fatigue in knee extensors (-55%) and increased muscle strength in knee flexors and extensors (+15 to +30%), while HbA1C decreased (-18%). In addition, the exercising patients showed sizeable improvements in HRQoL: physical function (+53%), vitality (+21%) and mental health (+40%). Conclusion: 12-weeks of combined aerobic-resistance exercise was highly effective to improve muscle strength and fatigue, glycemic control and several aspects of HRQoL in T2DM patients. These data encourage the use of aerobic and resistance exercise in the good clinical care of T2DM.

Envelhecer bem e de forma bem sucedida é o que todas as pessoas aspiram.O desejo humano em acrescentar anos de vida saudável no decorrer da sua velhice tem ganhado cada vez mais reconhecimento à luz dos olhos da comunidade científica, médica e sociedade civil. Este despertar da motricidade humana para o campo da gerontologia enquadra-se num paradigma desenvolvimental salutogénico em que bem estar e qualidade de vida na idade mais avançada é multifatorial capaz de interagir com as pessoas no seu todo a nível bio-psico-social. Permitindo segurança, participação, oportunidades e independência. As últimas décadas de investigação em que o interesse esteve voltado para a recuperação, manutenção e prevenção de capacidades físicas e cognitivas suportaram com elevada qualidade a diversidade de formas de programar intervenções práticas de exercício para pessoas idosas enaltecendo a pertinência dos programas integrarem simultaneamente a exploração destas capacidades. Este livro com caráter didático pretende criar uma ponte entre o que a ciência tem alcançado permitindo aos profissionais das ciências do desporto e técnicos de Gerontomotricidade um instrumento orientador e mediador no apoio técnico-pedagógico para organização, planeamento e implementação de boas práticas na atuação com pessoas idosas. Adicionalmente é do senso comum dos autores que carece literatura didática prática neste âmbito. Este livro tenciona nortear o leitor para propostas que tornem a concretização de um programa de exercício físico completo e qualificado em asegurar o trato das necessidades e adequabilidade aos idosos. Está composto por uma estrutura quem envolve 6 capítulos. O Capítulo 1. A gerontomotricidade como área de conhecimento e de intervençãoem que traduz ao leitor o campo desta sub-área da motricidade humana dando a conhecer as suas raízes, os seus princípios, principais objetivos de trabalho bem como recemendações para prática de atividade física; OCapitulo 2 - O Envelhecimento e Adaptabilidade Funcionalcontribuindo com uma informação rica no contexto das alterações fisiológicas inerentes ao processo de envelhecimento junto a uma paralelismo a adaptabilidade funcional; O Capítulo 3 - Funcionamento Cognitivo e Gerontomotricidadetransmite o conhecimento de habilidades cognitivas que parecem beneficiar da atividade física como a atenção, funções executivas e velocidade de processamento informacional, explica sobre os mecanismos que suportam a relação entre atividade física e funcionamento cognitivo e sobre a importância dada na otimização das práticas em dupla tarefa.OCapitulo 4 - Avaliação da aptidão física funcional na pessoa idosaapresenta uma seleção de testes físicos extremamente adequados às características e necessidades das pessoas idosas. Além de serem propostas convencionais são válidas frente aos parâmetros físicos que são sugeridos a serem explorados assim como fiáveis quanto aplicabilidade. O Capítulo 5 - Uma proposta de programa de Gerontomotricidadepropõe uma organização de programa com um forte caráter pedagógico sugerindo uma calendarização anual que respeita uma progressão sequencial e contínua das atividades práticas a serem desenvolvidas. Por fim o Capítulo 6 - Implementação de programa de exercício físico sénior em autarquia. Uma realidade em Portugaltrata-se de um capítulo ambicioso em que promove a prática empoderada de propostas de Envelhecimento Ativo focado a orientar a implementação de programa de exercício físico especializado à idosos em autarquias. No seu todo, o livro Gerontomotricidade em Prática. Uma proposta atual de programa de exercício físico para pessoas idosas não se limita em instruir o leitor a uma abordagem única de atividades práticas. Vai-se mais além procura apoiar em todo o processo com reforço ao conhecimento técnico e organização de prática que não se tornem utópicas e sim uma emergente realidade.

Fibromyalgia (FM) is a chronic, rheumatic disease characterized by widespread myofascial pain, of unknown aetiology, having a major impact on quality of life (QOL). Available pharmacotherapy for FM is marginally effective. FM is associated with co-morbidities of gastrointestinal (GI) disorders and Irritable Bowel Syndrome (IBS). There is growing evidence that diets low in FODMAPs, “fermentable oligo-, di- or mono-saccharides and polyols” [Low FODMAP Diet (LFD)], are effective in treating IBS. The aim of this pilot study was to examine the effects of LFDs on symptoms of FM, especially with regard to pain, QOL and GI disorders. Methods A longitudinal study using LFD intervention was performed on 38, 51 ± 10 year-old, female patients diagnosed with FM for an average of 10 years, based on ACR (American College of Rheumatology) 2010 criteria. The study was conducted from January through May, 2015, using a four-week, repeated-assessment model, as follows: Moment 0 – introduction of the protocol to participants; Moment 1 – first assessment and delivery of individual LFD dietary plans; Moment 2 – second assessment and reintroduction of FODMAPs; Moment 3 – last assessment and final nutritional counselling. Assessment tools used were the following: RFIQ (Revised Fibromyalgia Impact Questionnaire), FSQ (Fibromyalgia Survey Questionnaire), IBS-SSS (Severity Score System), EQ-5D (Euro-QOL quality of life instrument), and VAS (Visual Analogue Scale). Daily consumption of FODMAPs was quantified based on published food content analyses. Statistical analyses included ANOVA, non-parametric Friedman, t-student and Chi-square tests, using SPSS 22 software. Results The mean scores of the 38 participants at the beginning of the study were: FSQ (severity of FM, 0–31) – 22 ± 4.4; RFIQ (0–100) – 65 ± 17; IBS-SSS (0–500) – 275 ± 101; and EQ-5D (0–100) – 48 ± 19. Mean adherence to dietary regimens was 86%, confirmed by significant difference in FODMAP intakes (25 g/day vs. 2.5 g/day; p < 0.01). Comparisons between the three moments of assessment showed significant (p < 0.01) declines in scores in VAS, FSQ, and RFIQ scores, in all domains measured. An important improvement was observed with a reduction in the severity of GI symptoms, with 50% reduction in IBS scores to 138 ± 117, following LFD therapy. A significant correlation (r = 0.36; p < 0.05) was found between improvements in FM impact (declined scores) and gastrointestinal scores. There was also a significant correlation (r = 0.65; p < 0.01) between “satisfaction with improvement” after introduction of LFDs and “diet adherence”, with satisfaction of the diet achieving 77% among participants. A significant difference was observed between patients who improved as compared to those that did not improve (Chi-square χ2 = 6.16; p < .05), showing that the probability of improvement, depends on the severity of the RFIQ score. Conclusions Implementation of diet therapy involving FODMAP restrictions, in this cohort of FM patients, resulted in a significant reduction in GI disorders and FM symptoms, including pain scores. These results need to be extended in future larger studies on dietary therapy for treatment of FM. Implications According to current scientific knowledge, these are the first relevant results found in an intervention with LFD therapy in FM and must be reproduced looking for a future dietetic approach in FM.

Aims: To compare the physical activity, sedentary activity and health-related quality of life (HRQoL) in institutionalized vs. non-institutionalized elderly, and to establish a pattern of relationship and prediction of physical and sedentary activity with physical and mental components of HRQoL. Methods: The sample consisted of 383 elderly with ≥ 75 years old (n=187 institutionalized and n=196 non-institutionalized). Were administered the International Physical Activity Questionnaire (IPAQ) and Short Form 36 Health Survey (SF-36) for evaluated the physical and sedentary activity and HRQoL. Also was used the Mini Mental State Examination (MMSE) as exclusion criteria for cognitive problems in the elderly. Results: Differences between institutionalized and non-institutionalized elderly were found in moderate-intensity activities and walking, a favour of non-institutionalized. The institutionalized elderly remain more minutes in sedentary activity. Also, were observed differences between both groups in physical component of HRQoL, a favour of non-institutionalized elderly. The mental component remained unchanged. The multivariate regression analyses showed that physical activity predicted the physical (8 to 12%) and mental (5 to 8%) components of HRQoL for institutionalized and non-institutionalized elderly. Conclusions: Non-institutionalized elderly were more physically active, spent less time in sedentary activity and showed better perception physical component of HRQoL that institutionalized elderly. An important and encouraging result of this study was that physical activity is a predictor of improved physical and mental component of HRQoL for institutionalized and non-institutionalized elderly.
