Older people's adherence to exercise programs is most commonly measured with dropout and attendance rates and is associated with a range of program and personal factors.
Impact of resistance exercise program on functional capacity and muscular strength of knee extensor in pre-frail community-dwelling older women: a randomized crossover trialEfeito de um programa de resistência muscular na capacidade funcional e na força muscular dos extensores do joelho em idosas pré-frágeis da comunidade: ensaio clínico aleatorizado do tipo crossover
AbstractBackground: Frailty syndrome in elderly people is characterized by a reduction of energy reserves and also by a decreased of resistance to stressors, resulting in an increase of vulnerability. Objective: The aim of this study was to verify the effect of a muscle-strengthening program with load in pre-frail elder women with regards to the functional capacity, knee extensor muscle strength and their correlation.Methods: Thrity-two pre-frail community-dwelling women participated in this study. Potential participants with cognitive impairment (MEEM), lower extremities orthopedic surgery, fractures, inability to walk unaided, neurological diseases, acute inflammatory disease, tumor growth, regular physical activity and current use of immunomodulators were excluded. All partcipants were evaluated by a
BackgroundParticipation of older people in a program of regular exercise is an effective strategy to minimize the physical decline associated with age. The purpose of this study was to assess adherence rates in older women enrolled in two different exercise programs (one aerobic exercise and one strength training) and identify any associated clinical or functional factors.MethodsThis was an exploratory observational study in a sample of 231 elderly women of mean age 70.5 years. We used a structured questionnaire with standardized tests to evaluate the relevant clinical and functional measures. A specific adherence questionnaire was developed by the researchers to determine motivators and barriers to exercise adherence.ResultsThe adherence rate was 49.70% in the aerobic exercise group and 56.20% in the strength training group. Multiple logistic regression models for motivation were significant (P=0.003) for the muscle strengthening group (R2=0.310) and also significant (P=0.008) for the aerobic exercise group (R2=0.154). A third regression model for barriers to exercise was significant (P=0.003) only for the muscle strengthening group (R2=0.236). The present study shows no direct relationship between worsening health status and poor adherence.ConclusionFactors related to adherence with exercise in the elderly are multifactorial.
The majority of analyses did not show any correlation between variables assessed by isokinetic dynamometer and handgrip dynamometer. Caution is required when generalizing handgrip strength as a predictor of global muscle strength in community-dwelling elderly women.
Objective: To compare the performance of elderly people with different levels of severity of dementia using questionnaires on basic activities of daily living (BADLs) and instrumental activities of daily living (IADLs). Also, to verify whether there were any association between the IADL questionnaires applied. Method: Ninety elderly people, aged 75.46 ± 7.66 years with a clinical diagnosis of dementia (DSM-IV/APA) who were seen at the Minas Gerais Reference Center for the Elderly, were randomized selected and classified according to the level of severity of their dementia (Clinical Dementia Rating). Their BADLs were assessed using the Katz Index and their IADLs by the Lawton-Brody and Pfeffer indexes. The Kruskal-Wallis and Mann-Whitney tests were used in order to investigate the elderly people's performance regarding BADLs, while the Spearman correlation was used to investigate the relationships among the IADL (α< 0.05). Results: Statistically significant differences in performance were found between the elderly people with different levels of severity of dementia, as assessed by the BADL and IADL questionnaires (p< 0.001). The IADL questionnaires presented significant correlation for the total sample (p< 0.0001; r = -0.818) as well as for the groups with mild dementia (p= 0.007; r = -0.530) and severe dementia (p< 0.0001; r = -0.723). Conclusion: The severity of the dementia process interfered with the elderly people's performance of the elderly in BADLs and IADLs. The IADLs were more affected in the early stages of dementia whereas the BADLs were more affected in the more advanced stages. Despite structural particularities, the IADL questionnaires utilized seemed to be measuring a common construct. The variability in the clinical condition of the individuals with moderate dementia may be an explanation for the lack of correlation between the questionnaires in this specific group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
