Effects of Brisk Walking on Physical Performance and Muscle Function in Community Dwelling Elderly Women

AbstractIntroduction The isokinetic dynamometer enables accurate assessment of muscle function. In Brazil, few studies have assessed the isokinetic muscle performance in older adults making interpretation and comparison of results with other studies.Objectives To conduct a descriptive analysis of the performance of the muscle flexor and extensor muscles of the knee joint in elderly community and compare the performance between the age groups 65-74 years and 75 years or more.Methods This is a cross sectional observational study with a convenience sample of 229 elderly community. For the analysis of muscle performance was used isokinetic dynamometer (Biodex System 3 Pro™) in the angular velocities of 60 °/s and 180 °/s. The variables evaluated were peak torque, peak torque normalized by body weight, total work normalized by body mass, total work, average power and agonist/antagonist ratio. Descriptive analysis was used to characterize the sample. For comparison between age groups was used Student's t-test with α = 0.05.Results The elderly women with older age showed a statistically significant decrease in most of the variables (p < 0.05) except for the agonist and antagonist knee (p = 0.398).Conclusions The isokinetic was a sensitive tool to characterize the modifications caused by aging on muscle function. Elderly with results below the lower limits of the confidence intervals for all variables certainly has a decreased strength for the age group evaluated and must be addressed therapeutically. The results can be used as a benchmark in clinical practice and future research.

AbstractThyroid hormones (THs) play a crucial role in the homeostasis of muscle function, such as myogenesis and energy metabolism, suggesting that the thyroid may be also involved in the entropic processes of muscle aging. The aim of the present study is to evaluate the effect of TH signaling on physical performance, muscle mass, and strength in a cohort of community-dwelling oldest-old subjects (> 90 years). The study population was selected in a rural area of central Italy (Mugello, Tuscany), and the design was cross-sectional. Four hundred seventy-five subjects (130 males and 345 females) were enrolled, representing about 65% of all the nonagenarians living in the Mugello area. After adjusting for multiple confounding factors (sex, age, diabetes, and levothyroxine administration), the lowest quartile of FT3/FT4 ratio distribution showed lower physical performance compared to the other quartiles (β ± SE: − 0.49 ± 0.12; p < 0.001), whereas the highest quartile of FT3/FT4 ratio was associated with higher skeletal muscle index (β ± SE: 1.11 ± 0.42; p = 0.009). In addition, the lowest quartile of FT4 showed a statistically significant higher handgrip strength (β ± SE: 1.78 ± 0.68; p = 0.009) compared to all other quartiles. This study demonstrates that nonagenarians with higher FT3/FT4 ratios had better preserved muscle function, therefore successfully overcoming the imbalance of homeostatic and entropic processes involved in muscle aging. However, we could not establish a cause-effect relationship due to the cross-sectional design of the study.

ABSTRACTBackground:This study investigates discrepancies between the confidence expressed by Korean elders in their balance and their actual physical performances according to sex and age. It also attempts to identify the factors responsible for such gaps or discrepancies.Methods:The Korean Longitudinal Study on Health and Aging (KLoSHA) was designed as a population-based prospective cohort study on the health and aging of Korean adults aged 65 years and over. We evaluated 1000 of 1118 randomly selected subjects in terms of activities-specific balance confidence (ABC) and performance in regard to balance and gait (POMA). Activities of daily living (ADL) and instrumental activities of daily living (IADL) were assessed to measure disability. Pain-related dysfunctions, depression and cognitive functions were assessed. Next, we assessed the relationship between balance confidence and physical performance and functioning by sex and age.Results:The balance confidence of elderly women was lower than that of elderly men, although the physical performances of men and women under the age of 80 were similar. Women showed increased functional disability related to lower extremity pain and closely associated with balance confidence. However, psychological variables such as depression and cognitive functioning did not affect balance confidence.Conclusion:We found a discrepancy between balance confidence and physical performance according to sex and age among Koreans elders. Low balance confidence among women elders was correlated with pain-related dysfunctions other than those reflected in POMA scores. Therefore, enhancing confidence and controlling pain as a means of preventing disability should be emphasized when developing models for maintaining and promoting health in elders.

Before And After

Background Aging is an irreversible process by which all living humans will pass, and the percentage of older population growth significantly in the last decades. There are an increasing evidence showing that independently older people, with autonomy and physical capacity, has better quality of life in comparison with others without self-sufficiency. Objective: Verify the changes on Quality-of-Life (QoL), body composition and physical performance (PF) of elderly women submitted to resistance training (RT). Methods: 16 elderly women participated in the study, that consisted in 12 weeks of Resistance training. The QoL with SF-36, the blood pressure (BP), hand-grip strength, anthropometry and physical performance to senior, was measured before and after of resistance training. Results: The main findings of this study were that the RT for 12 weeks are able to changes the self-perception of QoL of elderly women, simultaneously with decrease in percent of fat and increase in strength and PF. In addition, a maintenance of BP levels, flexibility and self-perception of pain and global health (QoL domains), were observed after this period. Conclusion: The study suggest that the 12 weeks of RT, twice a week, is able to ameliorate several physical fitness components and QoL domains, in community-dwelling elderly women.
